An Analytical Chemist's View of

Lignocellulosic Biomass

Lignocellulosic biomass comprises wood and agricultural residues, which are sources of

cellulose, hemicellulose, and lignin (the lignocellulosic fractions), and represents the major

biomass source. Each of these types of lignocellulosic fractions has its own particular

structural characteristics and chemistry, which can be exploited in chemical analyses. For

a general approach, the quality of the biomass used determines the product quality.

Therefore, reliable information is required about the chemical composition of the biomass

to establish the best use (e.g., most suitable conversion process and its conditions), which

will influence harvest and preparation steps. Then, analytical chemistry is required to

understand and control these processes, their raw materials, products, and residues.

Lignocellulosic Biomass and Its Usages

The estimated worldwide production of renewable biomass for use in biofuels, fibres, and

agriculture is currently 210.7 x 106 tons per year. An exact value is difficult to obtain

because there is a large variation in production between countries. However, the

importance of biomass to the modern economy is clear. Lignocellulosic biomass

comprises wood and agricultural residues, which are sources of cellulose, hemicellulose,

and lignin (the lignocellulosic fractions), and represents the major biomass source; since

plants can contain high amounts of lignin (18% to 35% w/w), cellulose (40% to 50% w/w),

and hemicellulose (10% to 35% w/w), lignocellulosic biomass are considered as one of the

most promising sources of industrial raw material. Each of these types of lignocellulosic

fractions has its own particular structural characteristics and chemistry, which can be

exploited in chemical analyses.

The biorefinery concept is an important strategy in the development of biomass usage and

is based on the concept of a productive biomass chain similar to the petrochemical chain:

fuels, energy, materials, bulk chemicals, and fine chemicals. Biorefineries use a large

number of conversion processes (chemical, biochemical, and thermochemical) as a result

of the chemical diversity of biomass and the high content of oxygen and water; analytical

chemistry is required to understand and control these processes, their raw materials,

products, and residues. The increase in the demand for bio-derived chemicals not only

offers a great number of opportunities for green technologies and processes which use

lignocellulosic biomass in biorefineries, based on the green chemistry principles, but it also

presents several challenges related to market prices and replacement of non-renewable

products (e.g., petrochemicals) for a renewable chemistry.

Analytical Techniques and their Application

For a general approach, the quality of the biomass used determines the product quality.

Therefore, reliable information is required about the chemical composition of the biomass

to establish the best use (e.g., most suitable conversion process and its conditions), which

will influence harvest and preparation steps. Conversion processes should be monitored

for their yield, integrity, safety, and environmental impact. Effluent or residues should be

monitored and analysed for environmental control. Co-products need to be monitored to

avoid interference with the product yield and product purity; however, co-products are also

a good opportunity to add value to the biomass chain. Finally, products need to be

monitored and analysed to determine their yields and purity and to ensure their quality. A

recent review summarises the main techniques and their application for the analysis of

biomass and its products (Vaz Jr. 2014). The most widely used analytical techniques for

lignocellulosic biomass and products are briefly described below:

Gravimetry - determination of water content, by means of drying and weighing the

material. Gravimetry can be applied for feedstock and product quality control;

Thermal analysis - determining the water content and ash, loss of mass for

constituents versus temperature, thermal stability, among other parameters

associated with temperature effects on the material: thermal gravimetric analysis

PAPERmaking!




(TGA) and differential scanning calorimetry (DSC) can be applied for processes,

feedstock, and products;

Chromatography (liquid and gas) - identification and quantification of organic

compounds (volatile, semi-volatile, and non-volatile) and inorganic, polar, and

nonpolar, such as sugars from cellulose and hemicellulose, and their products of

conversion processes: high performance liquid chromatography (HPLC) or ultrahigh

performance liquid chromatography (UPLC) with refractive index, ultraviolet–visible,

diode array, fluorescence, mass spectrometry, and light scattering detectors; gas

chromatography (CG) with flame ionisation, thermal conductivity, electron

conductivity, and mass spectrometry detectors can be applied for feedstock,

processes monitoring, and quality control of products;

Spectroscopy and spectrometry - identification and quantification of organic and

inorganic compounds or materials, polar and nonpolar, such as metals and by-

products, by means of radiation interaction or radiation production: nuclear

magnetic resonance, Fourier transform infrared, X-ray diffractometry and

fluorescence, ultraviolet and visible spectrophotometry, atomic absorption

spectrometry (AAS), optical emission spectrometry can be applied for feedstock,

process monitoring, and quality control of products;

Mass spectrometry - identification and quantification of organic compounds, by

means of molecular fragmentation - can be applied for process monitoring, to verify

the product purity, and for metabolic engineering approaches of plants to improve

fractions content (e.g., cellulose);

Microscopy (e.g., scanning electron microscopy, transmission electron microscopy,

and atomic force microscopy) - observation of surface atomic composition and

disposition of biomass components (morphology) – are frequently used for

lignocellulosic polymers (e.g., cellulose).

Conclusion

From the viewpoint of an analytical chemist, chemical analyses of lignocellulosic biomass

can provide information about its constitution for feedstock usage in conversion processes,

and information about its products, by-products (or co-products), and residues. Then,

analytical chemistry as part of chemical sciences can contribute to a bioeconomy based on

biomass use instead of non-renewable raw sources, as the oil, and an advance in biomass

knowledge to develop the best uses of each source material.

The disposal of industrial paper mill sludge waste is a big issue and has a great

importance all over the world. A study was conducted to determine the chemical properties

of recycled paper mill sludge (RPMS) and assess its possibilities for land application.

RPMS samples were collected from six different paper mills in Malaysia and analysed for

physical and chemical properties, heavy metals, polycyclic aromatic hydrocarbons, 13C-

NMR spectra and for the presence of dioxins/furans. Data show the RPMS therefore

contains significant amount of nutrients with safe levels of heavy metals and PAHs for

environment and can be used as a fertiliser and soil amendment for land application.

1. Introduction

The industrial sector plays a significant role in the growth of the world economy. The paper

recycling process produces a considerable amount of organic waste, which is not suitable

for the production of new paper. A huge quantity of the sludge produced by paper mills

with large usage of paper is considered as one of the most serious environmental

problems [1]. The increasing amount of sludge and its consequent treatments are very

sensitive environmental problems [2]. In Malaysia, the amount of mill solid waste produced

increased from 16,200 tons per day in 2001 to 19,100 tons in 2005 or an average of 0.8

kilogram per capita per day. The industrial sector in Malaysia produced about 30% of solid

wastes and this amount is increasing by about 4% annually [3]. The waste is also known

as recycled paper mill sludge (RPMS). Recycled paper mill sludges are complex mixtures

of fibrous recycled paper, inorganic solids and chemical additives used in the paper

manufacturing. This sludge is the final processed waste from the pulp and paper industries

which are generated from different stages of the paper making process, including the

sorting, pulping, screening, cleaning, deinking, refining, colour stripping and bleaching

processes. Paper mill sludges are composed of organic matter (mainly cellulose fibre from

wood or recycled paper) in which organic compounds are added to the paper or pulp while

inorganic compounds (mainly calcium carbonate, kaolinite and talc) are also utilised [4].

The disposal of RPMS is an inevitable problem for these industries. It has also been

reported that the main contributors to the escalating costs of waste disposal include

transportation and tipping fees and the process has a negative impact on the environment,

especially concerning odour and leachate. The present disposal practice is via landfill,

which might not be viable in the long run as land is getting scarce with escalating cost, and

this industry also faces increasingly stringent environmental regulations [5]. However,

several industries take irresponsible actions to decrease the cost of disposal by illicitly

dumping their waste. This situation will cause the negative pollution effect to the soil, water

and air.

The utilisation of waste material in a suitable manner of application will balance the

increasing demands of limited natural resources [6]. The high capital cost that is beyond

the ability of small capacity mills and even then, the surplus amount of sludge is still large

and has to be disposed as landfill [7]. Furthermore, direct applications on land are the

preferred method of utilising paper mill sludge which is also cost effective.

Paper mill sludge is an active organic material that has potential benefits as a source of

nutrients for crops, but potentially can pose significant environmental and public health

hazards. There is also limitation for spreading paper mill sludge on agricultural land. In

order to appropriately manage organic residues, it is important to thoroughly characterise

their chemical and physical properties and accurately assess the impacts of these

properties on soil fertility and site quality. Hence, this study was undertaken to determine

the chemical properties of recycled paper mill sludges (nutrients, heavy metals content

and organic contaminants) and to assess the possibilities of recycling this waste for

agricultural land application in a safer manner.

2. Experimental Section

2.1. Recycled Paper Mill Sludge Sampling

Recycled paper mill sludge (RPMS) was collected from six different paper mills from

Malaysia (Figure 1) in sufficient amount for the purposes of characterisation. The six

samples were assigned as PM1, PM2, PM3, PM4, PM5 and PM6. Recycled paper mill

sludge which was collected from the waste treatment plants of each mills was analysed for

physical and chemical characteristics. During the collection, the RPMS were in wet solid

form. They were brought to the laboratory, air dried and ground to pass through a 2mm

sieve for the analyses of the chemical properties.

Figure 1. Map of the sampling locations in Peninsular Malaysia for the paper mill sludges

used in this study.

2.2. Physical and Chemical Characteristics of Paper Mill Sludges

The dried paper mill sludges were analysed for moisture content, pH, organic carbon, total

N and total heavy metals. The laboratory analyses were performed on the sub-samples,

each in five replicates. The pH of the sludge was determined from the supernatant of the

mixed sample and distilled water ratio of 1:2.5 using a Beckman Digital pH meter

(Beckman Instruments Inc., CA, USA). EC was measured from a solution collected from

the saturated paste using the EC meter. Total carbon was measured by the combustion

technique [8] using a CR-412 carbon analyser (LECO Corporation, St. Joseph, MI, USA).

Organic matter (OM) content was calculated from loss on ignition (correction factor of

1.78) by using following formula:

OM = 1000 × (mass of oven dry soil – mass of ignited soil) / mass of oven dry soil.

Total nitrogen was determined using the modified Kjeldahl method [9]. Soil CEC was

determined by the NH4OAc (pH 7.0) method [10].

2.3. Determination of Total Heavy Metals in Recycled Paper Mill Sludge

The aqua regia method was used to extract total heavy metals in the sludge and soil [11].

Aqua regia is a mixture of concentrated hydrochloric acid (HCl) and nitric acid (HNO3) in

the ratio of 3:1. Evidently, aqua regia is the only extractant that can release most of the

components bound in the silicate matrix (residual fraction) [12]. Total metal concentrations

were determined using a PE5100 atomic absorption spectrophotometer (Perkin Elmer,

Wellesley, MA, USA) except for phosphorus (P) concentration in the extract which was

determined using the Quikchem FIA 8000 auto-analyser (Lachat Instruments, Loveland,

CO, USA).

2.4. Analytical Procedure for Polycyclic Aromatic Hydrocarbons

Determination of PAHs was carried out at the Centre of Excellence for Environmental

Forensics, Faculty of Environmental Studies, Universiti Putra Malaysia (UPM). The

samples were purified and fractionated according to the method for polycyclic aromatic

hydrocarbons (PAHs) [13]. Glassware for the experiment were rinsed sequentially with

methanol, acetone and hexane to remove any organic contaminants and kept in an oven

at 60°C. About 20g dry weights of the sludge samples were homogenised with anhydrous

sodium sulphate (Na2SO4) to remove excess water. Cellulose thimbles were filled with the

samples and then transferred into the glass chamber. Round-bottom flasks were filled with

300mL dichloromethane (DCM) and then set up together with the glass chamber and

heater in the extraction unit. The samples were then extracted using dichloromethane for

8h. The extracts were transferred into a pear-shape vial from the round-bottom flask after

volume of the extract was reduced to dryness by a rotary evaporator. Extracted samples

were purified and fractioned into aromatic fraction through silica gel column

chromatography. About 50μL of the PAH surrogate internal injection standard mixture

(10ppm each component; anthracene-d10 and chrysene-d12) were added to the extracts.

The extracts were transferred onto the top of 5% H2O deactivated silica gel column. The

flasks with reduced sample were rinsed with 20mL hexane: DCM (3:1v/v). The volume of

sample extracts was reduced to 2mL using a rotary evaporator for the next step which was

injection into the column chromatography. In the second step of sample introduction into

the column chromatography, fully activated silica gel was used to pack the column. The

PAHs fractions were eluted with 16mL of dichloromethane/hexane (1:3v/v). Each PAH

fraction was evaporated to approximately 1mL, transferred to a 1.5mL amber ampule, and

evaporated to dryness under a gentle stream of nitrogen, then re-dissolved in 50μL of

isooctane containing p-terphenyl-d14 which was used as an internal injection standard

(IISTD) for PAHs analysis for quantification and to eliminate errors due to variation in

sample injection. PAHs analyses were performed using an Agilent Technologies 5973A

quadrupole mass spectrometer integrated with an Agilent 6890 gas chromatograph

(Agilent Technologies, Santa Clara, CA, USA). A 30 m fused silica capillary column of

0.25mm i.d. and 0.25μm film thickness using helium as carrier gas was carried in the

analysis. GC-MS operating conditions were set at 70eV ionization potential with the source

at 200°C and electron multiplier voltage at ~2000eV. The injection port was maintained at

310 °C and the sample was injected with splitless mode followed by purging for 1min after

the injection. Column temperature was held at 70°C for 2min, then programmed at

30°C/min to 150°C, and then 4°C/min to 310°C and held for 10min. A selected ion

monitoring method was employed after a delay of 4min. PAHs were monitored at:

m/z = 178 (phenanthrene anthracene),

m/z = 192 (3-methylphenanthrene, 2-methylphenanthrene, 2-methyl-anthracene, 9-

methylphenanthrene, 1-methylphenanthrene),

m/z = 202 (fluoranthene, pyrene),

m/z = 216 (1-methylpyrene),

m/z = 228 (chrysene, benzo[a]anthracene),

m/z = 252 (benzo[k]fluoranthene, benzo[e]acephenanthrylene, benzo[e]pyrene,

benzo[a]pyrene),

m/z = 278 (dibenzo[a,h]anthracene).

2.5. Analytical Procedure for Dioxin/Furan

Determination of Dioxin/Furan was carried out by the Doping Control Centre (DCC),

Universiti Sains Malaysia (USM), Pulau Pinang, Malaysia. MA modified method was

developed according to USEPA 8290 and 1613. The dioxin/furan analyses were carried

out using gas chromatography-high resolution mass spectrometry (GC-HRMS). Only one

paper mill sample was used to determine the dioxin/furan levels, which was then used to

represent the dioxin/furan content for sludge produced in Malaysia. Paper Mill 2 (PM2)

was selected because this sludge was also used for further studies (laboratory,

glasshouse and field conditions).

3. Results and Discussion

3.1. Physico-Chemical Characteristics of Paper Mill Sludges

The paper mill sludges produced by the paper industries in Malaysia were wet, sticky and

had a strong odour (Figure 2). Almost all mill sludges which were collected from the

various mills has similar characteristics, except for the contents of nutrients and heavy

metals which varied from each other. The moisture content in the sludge ranged from

45.78%–78.32% with an average of 65.08%. Pulp and paper mill sludges were generally

dewatered mechanically to increase the solids content, reduce the volume and weight and

improve their handling properties (Table 1). The composting of paper mill is recognised as

the most adequate pre-treatment in order to obtain a material which may respond more

efficiently with reduced odour and can help sanitise the material [14].

The mean pH value of the paper mill sludges was 7.09 (Table 1). The alkalinity of paper

mill sludges typically arises from causticising materials used in the pulping process and/or

PAPERmaking!




CaCO3 used in the paper finishing process. Most of the agricultural soils in Malaysia are

acidic in nature with low soil pH. Hence, in the sludge contains CaCO3 that could be

helpful for the soil improvement. In addition, paper sludge is suitable for land application

because CaCO3 can help neutralise soil acidity due to the cellulosic fibre content that can

hold moisture in the soil system. The electrical conductivity values of the six paper mill

sludges ranged from 0.51–3.08mS·cm−1. An EC level of < 2mS·cm−1 in soil and irrigation

water is generally considered a safe level for plants. However, most of the plants can

tolerate soils with an EC of 3–4mS·cm−1.

Figure 2. Physical appearances of different paper mill (PM) sludges from Peninsular

Malaysia.

The CEC values of paper mill sludges ranged from 3.33–28.07cmol (+) kg–1. Average CEC

content is 14.43cmol (+) kg–1 (Table 1). Reported CEC values of paper mill sludges from

earlier studies varied widely from 5.3 to 297cmol (+) kg–1 [15–19]. Differences in CEC may

reflect differences in sludge composition, organic matter fraction and/or clay content [20].

The N content of the paper mill sludges ranged from 0.31% to 4.05%. Average N content

was 1.45% (Table 1). In this study, the P content of paper mill sludges ranged from 0.02 to

0.78% with an average P content is 0.18%. Nitrogen and P, which are essential for

microbial metabolism, are typically added to wastewater during the secondary treatment

process which increases the N and P concentrations of the paper mill sludges [21] with N

contents ranging from 0.6% to 8.8% with a median value of 2.3% [22]. Industrial

wastewaters from operations like detergent manufacturing and metal coating processes

may present P levels higher than 10mg·L−1 [23]. The carbon content of the paper mill

sludges ranged from 18.92% to 33.67% with an average value of 25.61%. The C:N ratios

of the paper mill sludges were calculated to be 8.31–75.48. The National Council for Air

PAPERmaking!




and Stream Improvement [24] reported that the C:N ratios for paper mill sludge can range

from 6 to 115:1. The organic matter content of paper mill sludges ranged from 32.54% to

57.91% with an average value of 44.04%. The high organic matter content is an extra

benefit for the soils that will improve soil fertility and enhance the soils’ physical properties.

* PM = Paper mill, # Classifications were followed for land spreading of pulp and paper mill

sludge by the British Columbia Pulp and paper Association [25],

** Investigation Level for Malaysian soils which the level is taken at the 95th percentile of

the heavy metals data for agricultural soils [26].

The K content of the paper mill sludges ranged from 0.02% to 0.42% with an average K

content of 0.12% (Table 1) that shows its lower quantity. Generally, pulp and paper mill

sludges do not provide significant quantities of K [27].

The Ca and Mg contents ranged from 0.36%–1.28% and 0.41%–1.06%, respectively

(Table 1). Pulp and paper mill sludges, often contain significant quantities of Ca, and

sometimes Mg, in the form of carbonates and hydroxides, and have been proven to

effectively neutralise soil acidity. In projects where pulp and paper mill sludges were used

to reclaim mine tailings, the liming effect of the pulp and paper mill sludges have proven to

be one of the primary benefits to soil fertility [28].

PAPERmaking!




In the paper mill sludge, Na content ranged from 0.64% to 0.88%. Meanwhile, the Al

content ranged from 1.09%–1.68% (Table 1). Sodium and Al can occur in pulp and paper

mill sludges at levels higher than would typically be found in non-amended soils. However,

some studies to monitor these higher contents of Na and Al have been carried out for land

application with these residuals [29]. Sodium is used in the pulping process as sodium

hydroxide and Al is associated with the use of clays in the paper making process and the

use of Al salts (e.g., aluminium sulphate) in the wastewater treatment process [30].

3.2. Heavy Metals Concentrations of Recycled Paper Mill Sludges

The heavy metals concentrations in the paper mill sludge is one of the major issues as it

needs to be proven that either heavy metals are above the critical limits or not, which may

increase the concentration in the soil. After the analysis it was found that the concentration

of heavy metals in the paper mill sludge varied among different paper mills (Table 2). In

this study, guidelines for land spreading of pulp and paper mill sludge which were followed

by the British Columbia Pulp and paper Association, Lands and Parks [25] were used.

From the regulation, only paper mill sludges of Class 1 and Class 2 can be allowed for

application on agricultural lands.

Total concentrations of heavy metals in the six paper mills, with the exception of Cr, were

above the Investigation Level for Malaysian soils [26], which is the level taken at the 95th

percentile of the heavy metals data for agricultural soils of Malaysia. Camberato et al. [21]

surveyed several organic residues, including pulp and paper mill sludges and biosolids,

and reported that the levels of the regulated heavy metals in pulp and paper mill sludges

were lower than those found in biosolids, but slightly higher than the “background” levels

of these metals in soils.

The Cu content of paper mill sludges ranged from 83 to 199mg·kg−1 with an average of

130.38 mg·kg−1 which is above the Class 1 limit of 100mg·kg−1. Beauchamp et al. [31]

reported that concentration of Cu in paper mill sludge varied between 84 and 118mg·kg−1.

Copper was determined in different chemical additives in the paper making process, and

the analyses of the inks (cyan ink) showed a concentration of 10,685μg·g−1 of Cu.

Therefore, the source of Cu content in the paper mill sludge is likely due to the presence of

cyan ink.

The lead (Pb) content of paper mill sludges ranged from 43 to 328 mg·kg−1 with an

average of 126.5mg·kg−1 which is also above the Class 1 limit of 150mg·kg−1. In this study,

the Cd content of paper mill sludges ranged from 1.3 to 4.09mg·kg−1 (which is above the

Class 1 limit of 3mg·kg−1) with an average Cd content of 2.34%. Concentrations of Cr, Zn

and Ni in the paper mill sludge of the six mills were well below the standard concentration

of Class 1.

The average total concentration of Mn and Fe in six paper mill sludges analysed were

203mg·kg−1 and 0.34%, respectively. No standard was available for concentrations of Mn

PAPERmaking!




and Fe. However, these metals are valuable micronutrients, therefore, the agronomic

application rates were taken into consideration. According to Murray [32], the presence of

Fe is more likely linked to the addition of kaolin, the clay used to coat paper which contains

1% Fe2O3. Furthermore, Fe content in paper mill sludge is negligible compared to the level

found in soil, that is lesser than 50,000μg·g−1 [33].

Heavy metal levels in pulp and paper mill sludges are generally low enough that the

application rates to soil will not be limited by the heavy metals content [34,35]. According

to Camberato et al. [21], paper mill sludges generally have lesser metal concentrations

than municipal waste biosolids and well within regulatory limits.

Similar results were reported by Li et al. [36] and Lu et al. [37] in that the metals of

prepared paper mill sludges the major toxic metal was Ba, followed by Cu, Zn, Pb and Cr,

which were lower than the thresholds prescribed in GB 5085.3-2007. The use of these

types of sludges is not harmful for the soil and plants due to have less concentrations of

the heavy metals and could be useful as soil amendments.

3.3. Organic Contaminants of Polycyclic Aromatic Hydrocarbons

Seventeen polycyclic aromatic hydrocarbons (PAHs) were analysed in this study (Table 3).

The PAHs have received special attention since they have long been recognised as

hazardous environmental chemicals. The total concentrations of the 17 PAHs found in the

six paper mill sludges were within the range of 218.04 to 3646.67ng·g−1. The highest

concentration of total PAHs were recorded for sludge from Paper Mill 3 and the lowest was

recorded for Paper Mill 2. The total PAHs in raw paper mill sludge was less than 6ng·g−1

(the value recommended by the draft directive of the European Union for the land disposal

of sludges) [31]. Seventeen PAHs were detected at concentrations below the standard of

Class 2 followed by the British Columbia Pulp and paper Association, Lands and Parks

[25]. In addition, the paper mill sludges showed lower PAHs concentration than some

Canadian sewage sludges (traced to 100ng·g−1) that were used in agriculture [38].

3.4. Dioxins and Furans

The presence of trace organic components in pulp and paper solid residues either as

contaminants or by-products of the particular process has been an area of concern for

regulatory agencies and the general public. A primary concern in the land application of

pulp and paper mill residues is due to the presence of trace amounts of chlorinated dioxins

and furans. The concentration of dioxins and furans in the Paper Mill 2 sludge was

4.32pg·g−1, which is well below the Class 1 standard (10pg·g−1). The low dioxin content

makes paper mill sludge a potential organic material for land application in Malaysia. The

presence of total dioxin equivalents varied from 1 to 48ng·TEQ·kg−1 in Ontario (39) and

from 2 to 14ng·TEQ·kg−1 in Quebec. Meanwhile, the Maine Department of Environmental

Protection (USA) has stated that sludges containing 27pg·g−1 or lower are approved for

agricultural applications, while levels of 28–250pg·g−1 are restricted to non-agricultural

uses [39]. The RPMS has good potential to manage industrial wastes as a resource

through waste recovery that will create alternative resources for landfilling [40] and will

minimise the negative impact of waste on the environment and human health.

compounds in recycled paper mill sludges of different Malaysian paper mills.

* PAHs = polycyclic aromatic hydrocarbons (PAHs), # PM = paper mill, n.d. the value of

the PAHs were not detected in the analysis. Classifications were followed for land

spreading of pulp and paper mill sludge by the British Columbia Pulp and paper

Association [25].

3.5. 13C-NMR Spectra of Paper Mill Sludge

Among the various paper mills it was found that PM2 was the better sludge compared to

the other as it has high in moisture content, pH, EC, C, OM, CEC, lower in heavy metals,

PAHs, and dioxins and furans. With these all properties it can be utilised for the

improvement of acidic soils (most of the agricultural soils in Malaysia) and can be selected

for further use in laboratory, glasshouse and field studies. Hence, only PM2 was chosen to

record the 13C-NMR spectra due to its better suitability for land application (Figure 3). The

spectrum of raw RPMS showed the presence of peaks at 20, 23, 31, 56, 63, 65, 72, 75,

83, 89, 102, 106 and 174ppm. Jackson and Line [41] reported a similar 13C-NMR

spectrum for paper mill sludge in their study. The peaks at 20, 23 and 31ppm are

attributable to non-substituted alkyl carbons. The most prominent peak was centred at

31ppm, which suggests the presence of methylene (-CH2) groups in long aliphatic chains,

with a possible contribution from lipids and proteins too. Since no phenolic signals were

present in the spectrum (145–160), the RPMS could be assumed to contain little or no

lignin. The only signal that may indicate the presence of lignin was at 56ppm which is

usually assigned to methoxyl groups (OCH3) associated to lignin and lignin-like products

[41].

Figure 3. The 13C-NMR spectra of raw RPMS.

The presence of N alkyl C may also contributed to this resonance region. The large

doublet between 72 and 75ppm was due to the C-2, C-3 and C-5 carbons of cellulose and

the peak at 63 and 65ppm was due to the cellulose C-6 carbon. The signal at 89ppm and

highly shielded shoulder at 83ppm were due to presence of cellulose carbon C-4. Usually

the peaks at 72 and 106ppm are thought to correspond to resonance of carbons in

polysaccharides rings and to anomeric carbons in polysaccharides [42]. Furthermore,

Schmidt et al. [43] observed the signal at 72 and 106ppm together with a shoulder around

65 to 90ppm, most likely due to polysaccharides. The peak at 103ppm was due to

hemicellulose. The high resonance at 174ppm may arise from phenolate, carboxylic and

amide groups [44]. The 13C NMR obtained in this study suggested that the RPMS

consisted of chemically isolated cellulose and contains little lignin plus hemicellulose-like

material. The high cellulose content in the paper mill sludge may be accounted for in part

by mechanical and chemical degradation occurring during paper manufacture and

bleaching. The lack and comparatively low level of lignin was due to the bleaching

process. The mechanical degradation of polysaccharides during paper manufacturing may

thus be responsible for the production of paper mill sludge with a high cellulose and low

lignin content.

3.6. FTIR Spectra of Paper Mill Sludge

The FTIR spectrum complemented the structural information obtained in the 13C-NMR

spectrum. Infrared spectroscopy is a technique used to identify various functional groups

in unknown substances via the identification of bond vibrations at designated wavelengths.

The FTIR spectrum for the raw RPMS of Paper Mill 2 (PM2) (Figure 4) showed a broad

band around 3389cm−1 corresponding to OH stretching of phenolic OH groups. The band

attributed to the hydroxyl group and water at 3700–4000cm−1 was also detected in the raw

and RPMS compost. The moisture of raw and RPMS compost was found to be higher than

the mineral soil. However, the intensity was too weak and considered insignificant. A

distinct peak at 2924cm−1 corresponding to C-H stretching of the CH2 groups, indicates

PAPERmaking!




the presence of various amino acids. This band may also be the characteristic for the

presence of aliphatic methylene groups in these compounds. The weak C≡C stretching

band of alkyne molecules normally occurs in the region of 2231cm−1. The C=O stretching

at peak 1642cm−1 was protein of amide I’s origin. Giovanela et al. [45] suggested that

nitrogen bands in the IR spectrum are mostly due to the presence of amide groups.

Aliphatic C-H bending was observed with the peak at 1420cm−1. The band at 1260cm−1

can be assigned to the C-O stretch of carboxylic acids and to the C-N stretch of amides

amide III). According to the findings of Matias et al. [46], the peaks detected around

1260cm−1 were typical of lignin. A very strong peak detected near 1014cm−1 was assigned

to C-O stretching of polysaccharide-like substances. A sharp band at 875cm−1 was

assigned to the C-O out of plane bend of carbonates [47]. The stretching vibration

assigned to the C-S linkage occurred in the region at 700–600cm−1. Meanwhile,

brominated compounds appeared in the 600–500cm−1 infrared band region [48].

4. Conclusions

The study demonstrated that recycled paper mill sludge has potential and can be used as

a fertiliser applied for soil amendment. The application of recycled paper mill sludge to

tropical acidic soils can provide substantial benefits such as neutralisation of soil acidity,

increased organic matter and other essential nutrients. Composting may be a viable option

for recycled paper mill sludge as it can enhance its quality, since the physical properties of

paper mill sludge are practical. However, the uptake of heavy metals by crops and the fate

of these heavy metals in soils should be monitored to avoid the potential for soil and water

pollution.

Banknotes have been an integral part of buying and selling for many years. There are

about 7 billion Banknote leaves in Iran that have been in circulation in a 5-year period.

This amount of Banknotes and the frequency with which they are touched can promote

transmission of many pathogenic factors, especially bacteria. Based on scientific research

results, Banknotes are seriously contaminated and must be considered a potential danger

to society. In this study, for antibacterial Banknote paper production, 100ppm of Nanosilver

was used as an antibacterial agent accompanied by cationic polyacrylamide as retention

aid. The results showed that handsheets strengths decreased with increasing of

Nanosilver absorption, but antibacterial properties of handsheets increased by increasing

of Nanosilver absorption so that the most antibacterial properties for handsheets were

achieved at the 1% level of retention aid addition.

INTRODUCTION

Banknotes have been a part of commercial exchanges from the long past. Perhaps no

other object has been in such frequent daily use within societies. But there has been an

unfortunate lack of proper maintenance of Banknotes, which are a likely cause of many

hygienic problems (Pinner and Teutsch 1996). Studies concerned with the recognition of

pathogenic factors affecting Banknotes have shown that there are Gram-positive

Staphylococcus aureus and Gram-negative Escherichia coli on 13% of coins and 42% of

Banknotes in the US (Abrams and Waterman 1972). Also, investigations in China and

Germany have shown that most microbes can remain viable on Banknotes for long periods

and feed on the fatty materials that have accumulated on them (Zhang 1984). On the other

hand, studies of Banknote contamination in Egypt have shown that 65% of the Banknotes

were contaminated with intestinal bacteria (Dave 2005). Escherichia coli bacteria belong to

a big and various family of bacteria, some species of which cause diseases such as

diarrhoea, urinary channel infections, and respiratory conditions. This type of bacteria is

one of the important factors of traveller’s diarrhoea. It has been reported that Escherichia

coli bacteria was observed on 60% of Banknotes in butcheries, 10% in poultry shops, and

5% in fish food shops and confectioneries (Zarei et al. 2008). The other pathologic factor is

the Staphylococcus aureus family. The toxin of this bacteria causes vertigo, diarrhoea,

vomiting, skin infection, marrow infection, and blood infection (Leyinson et al. 2000). It was

further reported that 55% of Banknotes in butcheries, 40% in ice-cream shops, 30% in

bakeries, 25% in fast food establishments, and 10% in confectioneries were polluted with

Staphylococcus aureus bacteria (Zarei et al. 2008). Due to pathogenic factors resistant

against medications and antibiotics, it is difficult to effectively inhibit infectious diseases.

Development of tolerance by bacteria against the available antibiotics is a serious problem

affecting the general health. In this regard, nanotechnology opens new ways to fight and

prevent diseases by confronting the problem at an atomic scale (Kermanshahi 2008).

Among the best nanomaterials with antimicrobial properties, nano-metals that show high

chemical activities by surface crystallographic structure are especially significant. Among

these materials are products incorporating silver ions and silver-based compounds.

Nanosilver particles have antibacterial, antifungal, and antiviral properties, and

antibacterial surfaces can be created by adding small amounts of this material; even a

small quantity equates to many particles per unit area (Kermanshahi 2008). It has been

found that a Nanosilver suspension was able to eliminate many of the recognised bacteria

and even HIV viruses (Csreen et al. 2007). Nanosilver particles elliminate bacteria by

closing up respiratory tracts and by affecting the metabolism and reproduction of the

microorganism (Kelasen 2000).

An investigation was performed on two materials, chitosan and Nanosilver particles to

produce filter paper (Imani et al. 2011). Nanosilver particles were applied as negatively

charged layers over the fibres (LBL). It was found that with increasing numbers of the

layers, there were increases antibacterial properties, so that bacteria growth at eight layers

of the mentioned materials, as measured by a turbidity test, reached to zero. Also, the

antibacterial property of papers was assessed against five types of bacteria. The effects of

different antibacterial materials were different. Chitosan showed a better effect on Basibs

Sobtilitis bacteria. By contrast, Nanosilver particles were more efficacious against

Staphylococcus aureus and Escherichia coli (Imani et al. 2011). In another investigation to

achieve better performance of silver particles, CFGI compound was produced on fibres

pretreated with the chelating monomer glycidyl methacrylate-iminodi acetic acid (Gma-

ida), and this treatment caused more bonding of Nanosilver particles to the fibres.

Antibacterial performance was improved. With increasing concentration of Gma-ida

solution, more silver was absorbed to fibres. Nanosilver with a particle size of 75nm was

said to have better performance (Chen and Chiang 2008). Also, Nanosilver particles with

size of 25nm and concentration of 25 and 50ppm on the basis of ethanol were used for

making antibacterial cloth fibres that were added to cloth before and after dyeing. When

cloth was examined with an antibacterial test after dyeing, it showed more efficacy. The

suitable concentration of Nanosilver suspension to cloth treatment was reported as 50ppm

(Lee and Yeo, 2003).

Despite the fact that most infectious diseases can be transferred by touching biotic objects

such as Banknotes (Pinner and Teutsch 1996), no research has been reported about

making antibacterial Banknote paper. So the present study may be unique in its

consideration of Nanosilver particles due to antibacterial properties, non-toxicity, and

environmental friendly character as an antibacterial agent in Banknote paper production.

EXPERIMENTAL

Materials

Industrial cotton pulp was provided with a Schopper-Riegeler (oSR) value of 51, a

consistency of 3.1%, and a pH of 7.2. Also, Nanosilver (with 4000ppm concentration and

50nm particle size made by Rangdane Sharif company) and cationic polyacrylamide (with

medium cationic charge with Farinret K325 trademark made by Degussa Co.) were used

as antibacterial agent and retention aid, respectively. For antibacterial test of papers, the

two bacteria including Gram-negative Escherichia coli ATCC: 25922 and Gram-positive

Staphylococcus aureus, ATCC, which were provided by Dr. Ghahari of the medical

diagnosis laboratory in Babolsar city, were used. Brain Heart Infusion Broth (BHIB) and

Nutrient agar both made by Biolife company were used as liquid and solid culture medium,

respectively.

Methods

The pulp consistency was decreased to 0.3% and stirred to homogenise it for 15 minutes.

Cationic polyacrylamide (CPAM) with 1% concentration was added at the levels of 0, 0.3,

0.5, 0.7, and 1%, and then a constant level of 100ppm Nanosilver was added to the pulp.

Standard handsheets were made according to ISO 5269/1 and tested to evaluate physical

and mechanical properties (Table 1). Surface fibres in Banknote paper must have good

bonding so that they will not separate from the paper when the metal surface bearing the

tacky ink is separated from it during printing. Hence, a wax test was carried out, in which

the end part of a series of wax pieces is softened over a flame and put over the paper. The

wax pieces are separated from the paper surface rapidly, after 15 minutes. So the most

highest number of wax (representing higher strength) that doesn’t result in damage to the

paper is accepted as wax test.

Table 1. Tests and Standards

Antibacterial properties of handsheets were also assessed with a turbidity test, using a

Spectrophotometer 6300. Culture medium (BHIB) was placed in an autoclave (15min at

121°C), and treated and untreated handsheets were sterilised in an oven (0.5g, 2h and

150°C). Sterilised papers were inserted into a tube containing sterilised culture; then

0.05mL with 0.05% concentration of Escherichia coli and Staphylococcus aureus were

added separately and put into a shaker incubator (160rpm and 37°C) over one night.

Controls were also run in parallel. All experiments were conducted in triplicate. Also, some

pieces of paper were exposed on the solid cultures for evaluation of bacterial growth on

papers by optical microscope.

Statistical Analysis

All results were analysed by analysis of variance, and the Duncan test was used to

compare of averages. SPSS software was used for all analyses.

RESULTS AND DISCUSSION

Ash Content

As can be seen in Figure 1, ash content was increased with increasing CPAM level at a

95% confidence level. This can be due to amine groups on cationic polyacrylamide that

join well to fibre, leading to some fine flocks of the fibres and also trapping and retaining

the Nanosilver particles. This finding confirmed the results of Mokhtari (2011).

Figure 1. Effect of CPAM and Nanosilver on ash content of Banknote paper

Bulk Density

PAPERmaking!




Effects of CPAM and Nanosilver addition on the bulk density of handsheets are shown in

Figure 2. It is clear that by increasing the CPAM level, the bulk density was decreased.

This is probably due to fines retention between fibres. When dry strength agents such as

polyacrylamide adheres to fibres, it forms bridges between fibres and increases bonding

among the fibres (Scott 2006). The polyacrylamide, due to its cationic charge, adsorbs

fines and Nanosilver. Filling of empty space between fibres with Nanosilver may help

account for the observed decline in caliper. Also, cationic polyacrylamide causes hydrogen

bonding between fibres and prevents fines from being removed.

Figure 2. Effect of CPAM and Nanosilver on bulk of Banknote paper

Due to Interactions of CPAM and Nanosilver, fines absorb more and by forming of hard

and tiny flocks, caliper and subsequently bulk density of paper decrease. These results

also confirmed the finding of Ebrahimi (2011).

Smoothness

Smoothness of paper surface is an important property for printed paper such as

Banknotes, which need more smoothness compared to other grades of paper (Scott

2006). As Banknote paper is printed on both sides, there should be little difference

between the two sides.

Figure 3 shows that by adding CPAM and Nanosilver particles, smoothness of the paper

was increased compared to the control. It is worth noting that by adding of CPAM,

smoothness appeared to be decreased, but the apparent effect was not statistically

significant. Also, the difference between the two sides of paper is decreased by adding

CPAM level that it might be related to more absorption of fines (Miyanishi, 1998).

Smoothness difference between two sides of paper is decreased with an increasing

addition of retention aid.

Wax Test for the Surface Strength of Paper

Surface fibres should be firmly bonded to the sheet when detaching steel printing plates

and offset blankets from the surface, not separated or removed. One of the most common

methods of determining of paper strength in the Z-direction is the wax test. The wax

standards are numbered from 2A to 26A based on their adhesion power. In this study, the

wax index was 10A for all samples and without meaningful difference between all by

increasing in CPAM and Nanosilver levels (Figure 4).

Figure 3. Effect of CPAM and Nanosilver on smoothness of Banknote paper

In evaluation of raw material efficacy in banknote paper production, Erfani (2011) reported

a wax index of 16A. Due to use of a trimming refiner and also surface sizing in the final

step of a paper machine during Banknote production, a value of 10A could be accepted for

surface strength of handsheets.

Breaking Length

The most important factors affecting the breaking length of paper are the number and

quality of bondings between fibres (Testova 2006). Tensile strength directly shows a key

aspect of the durability and final functionality of many products such as Banknote.

According to the Figure 5, the breaking length decreased with the increase of CPAM level.

Reduction of breaking length due to retention aids addition can be attributed, at least in

part, to more absorption of Nanosilver and also increasing porosity or flocculated character

of Banknote paper (Roberts et al 1986). By increasing of bonding involving the fibre-

CPAM-silver combination, fibre-fibre bonding decreased, resulting in a considerable

decline in breaking length. Also, weak formation and flock formation decreases the

breaking length. As tensile strength decreased even without retention aids, much of the

decrease can be attributed to Nanosilver as a major factor (Imani 2011).

Figure 5. Effect of CPAM and Nanosilver on breaking length of Banknote paper

Tear Strength

Tear index depends on fibre length, individual fibre strength, and Relative Bonding Area

(RBA). In the case of a sheet having low RBA, tear strength is more dependent on fibre-

fibre bondings, whereas by increasing of bonding, individual fibre strength becomes crucial

in tear index (Testova 2006). Tear index is one of the paper quality parameter that affects

the runnability of a paper machine.

As can be seen in Figure 6, tear index was decreased with increasing consumption of

retention aid. This can be related to increased retention of fines as well as decreasing in

average fibre length. On the other hand, the presence of Nanosilver between fibres will

tend to reduce fibre bonding, leading to a decrease in tear strength. These results

confirmed Ebrahimi’s report (2011), which indicated that by increasing filler retention on

CMP fibre, tear strength was reduced.

Folding Endurance

This test involves a combination of tensile strength, elongation, flexibility, compatibility,

shear stresses, and relative fibre length change (Erfani 2011). According to Figure 7, by

PAPERmaking!




adding CPAM to the furnish, along with the addition of Nanosilver, the folding endurance

declined. This probably can be attributed to a lack of hydrogen bonding between cotton

fibres. Addition of filler in paper results in a weakening of the fibre network, lack of long

fibre in pulp suspension, and a higher level of fines in the paper; such changes are

consistent with a decrease in folding endurance (Erfani 2011). As can be seen in Figure 7,

folding strength of handsheets was very low and there was considerable difference

between the values obtained in the present work compared to the common level of

Banknote paper folds (about 5000). This difference probably can be attributed to the

properties of the pulp that was provided before the trimming refiner. A trimming refiner

causes fibre fibrillation and increases hydrogen bonds in paper machine before

papermaking.

Biological Test of Banknote paper

According to Figure 8, for both types of bacteria Staphylococcus aureus and Escherichia

coli, by increasing the amount of CPAM, the UV adsorption was reduced and the greatest

reduction was obtained when using retention aid at the 1% level. This shows that higher

PAPERmaking!




adsorption of Nanosilver led to higher anti-microbial effects in handsheets. Also, turbidity in

samples including Staphylococcus aureus was lower. As a rule, Gram-positive bacteria are

more sensitive to Nanosilver particles than Gram-negative bacteria due to a difference in

the cell walls. In Gram-positive bacteria, the cell wall is rich in mucopeptide component,

while in Gram-negative ones the cell wall just contains a thin layer of mucopeptide and is

primarily composed of lipoproteins and lipoprotein polysaccharides. Therefore, Escherichia

coli shows more resistance to antibacterial materials (Tassou and Nychas 1995). The

present findings confirmed the other results reported by Sondi et al. (2004) and Giange et

al. (2004). It is clear in Figure 8 that treated paper showed higher resistance to bacteria

than the reference samples.

Figure 8. Effect of CPAM and Nanosilver in Banknote paper on turbidity of bacterial

medium

Microscopic Investigation

Figure 9 shows the optical microscope images of papers on the solid culture in the vicinity

of bacteria. As can be seen, Esherichia coli was able to grow more abundantly and closer

to paper due to greater resistance to Nanosilver than Staphylococcus aureus. Therefore,

the inhibition zone in S. aureus was larger. These images confirm the results of the

previous section. The present findings are consistent with the results of Haji Mirza Baba et

al. (2011). The results provide evidence of the reaction mechanism of Nanosilver with

biological macromolecules, inhibition zone formation, and also the transformation of

microorganism by conversion of SH bond of proteins that are present on the bacterial

surfaces. These proteins give rise to a bulge in the outside of cell membranes and allow

passage of nutrients through the cell wall (Baumgartner and Cooper 1996; Sung Kaworn

et al. 2007). In this mechanism, Nanosilver particles release silver ions over time. These

ions convert SH bonds to SA-g bonds in the microorganism membrane during the

substitution reaction. In this way, Nanosilver particles deactivate protein, reduce

PAPERmaking!




permeability of membrane, and finally cause the cell death (Tahan et al. 2006; Fengetal

2000; Stoimenovetal 2002).

CONCLUSIONS

At present, much attention is being given to the addition of nanoparticles to achieve

essential interactions during the formation process of paper. Although usage of

nanoparticles can provide a lot of advantages, it is very important to determine how best to

use such products and how much of the nanoparticle is appropriate for the system. In fact,

due to the change in pulp composition and even in the nanoparticles themselves (in terms

of size and type), there are different interactions and changes in wet end chemistry. For

this reason in spite of positive effect of nano-particles, there is still a need for plenty of

research in order to achieve better and different utilisation of this system.

The present research was done to investigate the effect of poly-acrylamide and Nanosilver

on physical and mechanical properties of paper pulp. Five levels of cationic poly-acryl-

amide (0, 0.3, 0.5, 0.7, and 1%) were applied. Results showed that the best retention of

Nanosilver as well as paper properties were obtained in at the 0.3% level of CPAM

consumption.

Preservative properties of Nanosilver in recent decade have attracted much attention. In

this research, Nanosilver used in paper pulp as an additive led to decreasing physical and

mechanical properties of Banknote paper, but in terms of biological resistance to bacteria,

it was very effective. Anti-bacterial properties of paper were increased by applying of 1%

Nanosilver. By adding of low levels of Nanosilver in pulp suspension and then applying

supplemental refining of the fibre furnish, both anti-bacterial and mechanical properties of

Banknote paper likely will be increased.

5 Obstacles Guaranteed to Slow You

Down

Keith Johnston, www.truleadership.com

Many start-ups invest time, energy and money in setting the stage for rapid growth. They

develop elaborate marketing plans and hire a sales team to get the message out. They

also ensure that they will have the production capacity to deliver their solution to all the

customers who are going to rush to buy their products and services. With all this planning

and preparation 80% of them will not make it past the first 18 months, and 80% of those

that remain will be gone before they celebrate their 5th anniversary. There are many

reasons companies fail to reach the acceleration speed required to launch themselves into

the small elite group of companies that are successful. Most of those companies that fail in

the first 18 months had good plans, were well funded and had a promising value

proposition. So why do they lose momentum and fall back? What keeps them from

growing? In my experience with technology and IT service organisations, there are five

reasons start-ups fail to develop and maintain the momentum required to be successful.

This short item, aimed predominantly at entrepreneurs and start-up businesses, contains

much general ‘management’ information that can be translated to any type of business.

1. Ability to attract and retain high quality people: A company may start with a strong core

team when they launch their business, but to grow they need to be able to attract and retain a

steady stream of talented professionals. To attract top talent they need a compelling vision of

where the company is going and how the company’s growth will generate opportunities for

people to grow. Unfortunately the vision of and by itself will not retain top talent if the founders

do not have the leadership skills to keep their people engaged and motivated. Those

companies who find it difficult to retain top talent will frequently attribute this to an inability to

meet the compensation demands of the market. This is rarely the problem. People who are

engaged, learning new skills, empowered to make decisions, and are recognised for their

contribution will rarely seek greener pastures. It is incumbent upon the company’s leadership

team to ensure that the people they recruit see the company as a place where they can build a

career and have some fun doing it.

2. Communication Skills: The best vision and the best business plan are worthless if they

cannot be communicated in a compelling way. Customers will not agree to buy, and talented

people will not agree to work for you if you are unable to communicate your vision and the

value you offer. I recently received a phone call from the CEO of a start-up technology

company in Vancouver. He was in need of an immediate cash infusion to keep his company

alive and was asking my help in finding investors. As I listened to his plea for help, I did not

hear one compelling reason I could provide potential investors as to why they should part with

their money to bail this company out. He kept repeating that his technology would revolutionise

the industry, but he could not articulate how his technology was any different from what was

already in the market or what would cause his technology to develop a market share which

would generate the kind of cash flow that would provide investors with a satisfactory return on

their investment. He was not exciting or even confident. He sounded desperate and I could not

help but wonder if his communication skills were the reason he was finding himself in the

position he was in.

3. People Not Prepared for Rapid Acceleration: All too often I have been caught in rapidly

growing businesses where the business was growing faster than the people who were running

it. New staff were being hired and supervised by people with very little experience in managing

people. Young bright but inexperienced people were being thrown into situations where their

interpersonal skills were not adequate to deal with demanding customers or hard charging

staff. I saw a major consulting firm lose millions of dollars in fees during a period of rapid

growth as a result of promoting people into positions they were not prepared to handle.

Companies are quick to provide technical training but are slow to provide training in critical

interpersonal skills like communications, conflict management, negotiations etc. The result is

that their staff are not prepared to deal with people. They were unable to establish

relationships with the people who report to them or the customers who are looking to them to

solve their problems. In my experience, spanning more than thirty years, the biggest problems,

and in some cases biggest setbacks, came as a result of promoting people into positions of

responsibility without providing them with the skills needed to deal effectively with other

people.

4. Living in the weeds: I once worked for an executive who was constantly reminding me to

“get out of the weeds”. He was concerned with the amount of time I was spending managing

the people who reported to me. He told me that I should be spending more time with him

discussing strategy than I was dealing with tactical issues. I needed to do a better job of

empowering my staff and focus my attention on bigger longer term issues. I have noticed this

problem a lot with the clients I have worked with. In particular, I have seen entrepreneurs and

corporate executives who micro manage and take their eye off the vision they have for their

company. Living in the weeds results in missed opportunities, missed deadlines and a loss of

focus which results in arriving at your destination later than you thought or getting off track and

wasting time and resources recovering from setbacks which could have been avoided.

5. Strangling Innovation: It goes without saying that innovation is the fuel which drives the

success of any start-up company. Customers will not be attracted to new products and

services unless they have a compelling reason to do so. The companies that succeed are not

only innovative in their product and services, they have a culture of innovation and employ

innovative approaches to marketing, sales, production and how they treat employees. Given

the importance of innovation it is surprising how many companies strangle innovation by

placing weak or inexperienced leaders in positions of responsibility. Among the key factors

which strangle innovation are: micro management, tight control, inflexible processes, and

failure to empower the members of your team.

How prepared are you and your people to handle rapid growth? Do your people understand

the skills required to engage and motivate new staff? Do they know how to address the

interpersonal needs of customers, recruits, investors and other stake holders? In my recent

book, A Garage Full of Ferraris, I highlight the successes of 15 people who were able to

achieve their success by addressing the obstacles outlined above.

Customer Desertion: A Soaring Down

Impact on Business World

Harvinder Singh, Assistant Professor School of Business, Lovely Professional University, Punjab, India. E-mail: [email protected] The study of desertion provides insight into how to improve products and services offered to the targeted market by developing effective retention programs and consequently creating long-term relationships. But why is retention so important? It is not only because retaining a customer is cheaper than acquiring a new one, or because of the necessity of retaining customers until they are profitable. Rather, client retention is important because it is a value generation strategy for the business firm. Customer desertion is a major area of concern for today’s business world. As more and more customers are absconding, it affects the soaring down of business. This article focuses mainly on telecoms and financial services sectors, but contains much that is applicable to general business environments, including paper manufacture and merchanting.

Research problem The following study relates to customer desertion & retention. The major problem is that, the customer’s switchover to other companies and brands due to some factors, this affects the organisation’s sales and profitability. So, an attempt has been made to deeply examine the problem, factors and causes of customer desertion. Objectives of the study 1. To analyse the customer desertion factors and causes. 2. To recommend benchmarks for retention measurement and monitoring. Scope of the study This study will be helpful to the business organisations to analyse the causes of desertion. It will be very helpful to the entrepreneurs, organisations and management students to know the hidden facts of customer retention strategies and desertion and also reveal why customers leave a particular organisation. Literature Review Jacqueline Urquizo has emphasised that monitoring only desertion and retention index is not enough to improve the retention rate; comprehensive monitoring of the causes (internal and external) that provoke desertion is needed in order to track an effective change. Retention depends on the creation of a solid market by helping the customer to grow. The success of the customers is the success of the organisation. Ahmed et al. [1] studied the best strategies for retaining the customer and the practices one should follow to keep customers active and attached with the organisation for the profitability. Bob Thompson CEO, Customer Think Corporation [2], examined the secrets of retaining a customer and increasing profits. He suggested some strategies to retain customers in this modern era of competition. Janelle [3] studied the direct effect of perceived value dimensions (monetary, convenience, social emotional, conditional and epistemic value) on attitudinal and behavioural component of loyalty: commitment and behavioural intentions to use location based mobile services. This study revealed that the behavioural intentions were most influenced by conditional value, the context in which the service is used, followed closely by commitment and to some extent monetary value. Churchill et al. [4] investigated the choice criteria for a mobile phone operator in the Malaysian mobile Telecom market by the customers. Structural equation models were applied to test the propositions by means of a survey of a random sample of 400 mobile telecom customers from major cities in Malaysia. It was found that the price and service (quality hypothesis) are more important than the brand image hypothesis. Network quality is one of the important factors of overall service quality. Churchill et al. [5] explored the strategies that have been employed by the cell phone companies in South Africa in order to retain subscribers. This study evaluated the retention strategies that have been adopted by the cellular industry, where players are battling to retain customers or recruit new ones. The evaluation is based on the perceptions of the customers of the five cell phone network providers that operate in South Africa.

Doyle [6] conducted a study to investigate the variables which can help retain existing customers. The study identified price reasonability and call clarity as the strongest determinants of customer retention for the cellular industry of Pakistan. This study reveals that customer support services, value added services, user friendliness and customer complaints all had effects on customer satisfaction [7-9]. Causes of Desertion The causes of desertion are numerous and sometimes inter-related. To study them in greater detail and see their relative importance, this article analyses them separately. Figure 1 shows the general framework to analyse the causes of customer desertion. Desertion due to industry structure Growing competition: As a result of low entry barriers create a fragmented market with

numerous and diverse competitors. In general, the industry operates in fragmented markets, in which diverse participants in nature and size compete; as a result, the market share of each industry is diluted. A small business organisation may compete with a larger one, since they may not have significant cost disadvantages considering;

➢ The high level of personalised service

that is, in general, used throughout the industry which is difficult to automate or scale up.

➢ The very local clients.

Product and market adequacy: The basic model assumes a market that has to be developed, i.e. potential customers do not know the benefits of product company offers and that they have to be trained through an almost missionary activity where the representative visits nearby small towns. The implication of these conditions is that the customer is not profitable after the first visit but from subsequent ones, to recover expenses incurred in their product education. However, in the mature markets studied, customers have learned rapidly about the operation, convenience, advantages, and disadvantages of product and services. Many potential and current customers are well informed about the existence of the product offer, also having established an attitude towards it. Accordingly, business houses looking for new markets turn to segments with lower income or higher risk, where there is not necessarily the most adequate product, resulting in high attrition levels due to the lack of sustainability that incompatible product produces, or due the vulnerability of customers being approached. Regional economic factors: The micro entrepreneur’s regional economy also commonly influences desertion; this factor is related to the intuitive projection that the micro-entrepreneur makes on his or her future sales. The regional economy is an essential consideration in the decision to renew credit, regardless of the quality of the product offer. Although micro-entrepreneurs are capable of overcoming unemployment and managing

PAPERmaking!




economic fluctuations, not all of them have the same proclivity towards risk, which is related to their self-perception of capacity to handle these challenges. Desertion generated by business performance The reasons for desertion resulting from business performance are related to the value proposition it offers its customers. The satisfaction components show results of quantitative studies on the customer level of satisfaction. The graph (Figure 2) shows the components of customer satisfaction. The lowest satisfaction level was related to product features.

Satisfaction with product features: The market research uncovered the following issues related to dissatisfaction with the product features.

➢ Model centred on a single product: The single-product approach results in processes

and a culture that make the offer inflexible and limited in reach. Considering the nature of the micro-entrepreneur’s activity, flexibility is one key element to promoting client retention.

➢ Product perceived as standard: Customers perceive that price, amounts, and the

methodology (accessibility) are more or less the same among the operating organisations. The new product developments have limited innovations and add little value to the customer, however complicated the business control and operation.

➢ Changing product features: The customers are very much concerned about the new

product in the market and new features. So, the customer does not stick with one company for long; instead they shift most often for the use and desire of new features. In the case of mobiles and banking service we have found the major shift by the consumers.

➢ Company policies and norms: There are companies which change their policies very

quickly; in return the customers feel cheated. So, the customers like to change and their desertion is likely.

➢ Competitive prices by the companies: When companies, in an effort to increase

profitability, increase the price of the product, so, customers switch from one company to another as an advantage to buy product from other company. Satisfaction with customer service: Though the industry still has a lot of ground to cover with respect to improving customer service, since customers have lower expectations

PAPERmaking!




about service this makes it a less important cause for desertion. In addition, the personalisation and emotional involvement of the customer frequently replaces the service weaknesses. Substantial improvement in customer service in most cases requires significant investments in infrastructure, such as speedy IT systems, alternative channels for more convenience, bigger branches, which the companies often do not have the resources to build in the short term. Desertion caused by institution image Brand strategy is a factor that receives minimal attention in the industry given that a strong or renowned brand is not a key element for offering credit. It becomes relevant once the institution tries to enter into other markets such as the savings or insurance market or when faced with retention problems in some market segments. Desertion due to the characteristics of micro-entrepreneurs Many institutions take for granted their customers need to grow or to be successful. However, given the customer’s nature and business characteristics, this is not always true. Micro entrepreneurs have a variety of financial needs such as insurance or savings, or others such as training, networking, business advisory services and related micro business services. It is frequently overlooked that, for the customer is a means and not an end in and of itself. Customers do not seek product as such: rather they are looking for solutions to their needs. For example, an appliance store that helps the client finance the purchase through interest-bearing instalment payments is selling solutions. Customers have diverse attitudes towards credit, different personal and family goals, different entrepreneurial capacity, etc., so understanding the segments being served is important in order to know who the customer of the current value proposition would match better, so that there will be fewer desertions. Considering that goals drive peoples’ behaviour, fully understanding them as well as existing segments and their decision making process, is a basic element for developing an effective retention strategy. Which customer to retain Most business organisations wish to retain all their customers, without discrimination. However, considering that they must efficiently use their resources, focus is required to retain better customers who are at risk of leaving. In choosing who to focus its efforts upon, the organisation faces the dilemma of identifying who the most “valuable customers” are - the most profitable customers or the needy customer. The risk/value matrix shown illustrates a segmentation combining these variables (Figure 3). As per the above matrix, out of approximately 14865 customers, 47% are having low value/risk, 28% having medium value/risk. 24% having high value/risk, which developed with the purpose of focusing retention efforts on valuable customers who are at risk of leaving. Probability of leaving: The probability of leaving was established using the Arbitrary Variables Method, which is a mixture of qualitative and quantitative analysis combining numerical desertion data with appropriate weighting. The main quantitative information

was the time the customer was working with the organisation, the accumulated delinquency days, and his business activity. This axis can also be statistically determined with a desertion score whereby key variables are input into a statistical model that estimates the probability of desertion of other customers with similar characteristics. Below are some considerations that should be factored in when deciding whom to retain as a priority: Strategic importance: Opinion leaders, those belonging to the segment that fits well with the competencies of the business organisation or other potential growth segments. Profitability: Customer relevance often follows the “Pareto” rule, whereby 20% of the customers provide for 80% of profitability. It is important to differentiate whom to retain versus whom to reward. Retention and rewarding strategies are not equal; one could be necessary, the other being optional. Loyalty: Some customers are inherently more loyal than others, for reasons having to do with their profiles rather than something attributable to the organisation. Life time value (LTV): The discounted present value of future revenues that the customer would give to the organisation should he decide to stay, i.e. since the customer value is measured with respect to its future sale potential and not the current potential. It should be noted that not all organisations have information on customer related costs, so that proxies could be obtained while adequate information is captured on issues such as desertion. Desertion due to service dissatisfaction by customers Many customers are dissatisfied with the services offered by the organisation or company. The customers are very much service conscious and if the quality of service is poor then the customers will not opt for that company; neither will they refer somebody to visit the company, due to the poor service. Therefore the customer desertion will be high. Monitoring the Desertion In measuring performance with respect to client desertion, it is important to distinguish between monitoring (continuous measurement) and other basic forms of information gathering related to market research (undertaken at a specific point in time). In both cases, more important than the method of measurement is to define what is going to be done with the results. Collecting information on consumer behaviour and/or reasons for desertion causes from exit interviews or suggestion boxes, for example, are useless if these are not supported by a market intelligence system that would permit it to flow through and analyse at a strategic decision level. Moreover, the reasons for desertion do not substantially vary over time because customers’ behaviour and attitudes develop over time and therefore do not change quickly; market research efforts are a good alternative to analyse issues relating to desertion instead of regular monitoring of data which will not provide new information. Some business houses should have considered investing in sophisticated information systems – like customer relationship management (CRM) programs, which use data warehouses to mine information about clients (Figure 4).

Market Research versus Desertion Monitoring What is researched? Reasons for exit including external causes outside the organisational control, such as: competition market penetration, customer profile, organisational image, and the decision making process pertaining to leaving, among others. The purpose of the investigation is diagnosis. What is monitored? The effects of modifying a root cause. The idea of monitoring is to measure the impact and effectiveness of addressing a desertion driver. Monitoring ensures that retention measures are targeted at root causes. Desertion rate calculation The calculation of desertion rate and adjusting the desertion rate is done through a formula mentioned below.

where: DR = Desertion Rate.

EDR = Effective desertion rate (Customer Rate). N = New customers joined in period of analysis. CAb = Active customer at the beginning of the analysis period. CAe = Active customer at the end of the analysis period. CR = Customer left during the analysis period.

Considerations in the Measurement Process The following considerations are recommended to establish benchmarks and baselines for retention measurement. 1. Set a target What is the number you wish to reach? If you do not have a goal, then why monitor? 2. Observe the curve and not the measurement itself The curve indicates trends; an isolated number shows only one piece of information that could be contingent on other factors or temporary.

3. Apply the Pareto principle as a general rule Recognise that 20% of the customers contribute to 80% of the profits, or which 20% of the causes are resulting in 80% of the complaints or desertion, etc. 4. Use absolute numbers as well as percentages The percentage, being relative, must be supplemented with the factual value in numbers (e.g., indicate that a 15% desertion is the equivalent 3,500 customers). 5. Shortening the measurement period lowers the desertion index To avoid underestimating the amount of desertion, make the measurement period equivalent to the longest credit term of the MFI (e.g. 18 months). 6. Use moving averages to eliminate temporality and see the tendencies The average of the previous 12 months has to be measured on a monthly basis, thereby removing the seasonal desertion and considering that most customers had at least the chance not to renew during the last 12 months. 7. Define desertion in terms of customers and not products If you have more than one product or service such, as insurance, savings, or training, include the use of all products in the desertion index and not just credit products. 8. Make measurements in the same time To allow valid comparisons, use the same time period (be it day, week, month, or quarter). For instance, make measurements in the first week of May, and then the first week of June. Conclusions Desertion is endemic throughout industry and is a forewarning about the mismatch between the value offer delivered by the companies and the objectives of the entrepreneurs. The majority of former clients are not going to the competition nor are they resting, which suggests the causes have to do with industry weaknesses that will not be fixed by just letting all the players compete. Rather, dual measures are necessary: adjustments in market target as well as the value offer delivered. It is important to keep in mind that successful micro entrepreneurs are people who choose financing options based on the relative cost/benefit of any offer. Their intuitive rationale takes into consideration the convenience of credit renewal. References 1. Ahmad R, Buttle F (2002) International Journal of Bank Marketing 20: 5-16. 2.

Crepe Structure Measurement - Model Q4224-50

Honeywell’s Crepe Structure measurement analyses tissue quality by capturing high

resolution images of a moving sheet to identify important variables on creping process.

These allow optimisation of creping blade life while maintaining consistent quality. Longer

blade running time means less blade changes and more quality production without

process upsets. The sensor allows mill personnel to monitor tissue structure

characteristics online throughout the entire production process, facilitating immediate

corrective action if the quality deviates from targeted. Crepe Structure Measurement

provides an excellent tool for tissue process optimisation, troubleshooting and test runs for

selecting optimal chemicals and process operating points in real-time.

The image control unit inside the sensor controls both the camera and the illumination unit

for optimal image quality with varying machine speeds. Single-sided construction houses

camera and illumination on same side of the sheet. The captured image is analysed with

proprietary algorithms, producing numeric indicators characterising tissue crepe structure.

Imaging and analysis computation are done by sensor processor unit in real-time. Numeric

values of the measurements are then transferred to the system server for display, profiling

and trending. Captured images are periodically transferred to the Experion MX system

server for display.

Features & Benefits

The sensor measures the following crepe structure characteristics:

o Folds/length

o Macro Crepe

o Micro Crepe

o Impurity

o Caliper (this is an application dependent additional measurement)

Sensor module camera and illumination automatically adapts to different machine

speeds for the optimal image quality

Standard sensor modular design allows installation in any slot inside the measuring

head

There are no moving parts in the sensor module, which minimises maintenance

needs and ensures a long lifetime

Up to four images per scan are available in Experion MX from operator-defined

cross direction locations for visual analysis and trouble-shooting

An “Image Gallery” display shows 8 images each representing reel average crepe

structure characteristics. These are displayed around grade dependent reference

image for comparison

In single point operation, images are transferred periodically at a fixed rate for

operator observation

PAPERmaking!




Description

The measurement is designed for online use in the challenging tissue machine

environment. Fast image capture allows reel speeds up to 2600 m/min (8530 ft/min)

without reduction of image quality. The measurement automatically adjusts illumination

and imaging parameters for varying speeds. An intelligent operating algorithm mitigates

the effect of uneven illumination, ambient light, and dirt/dust build-up. Images are captured

and analysed at the rate of 10 Hz.

Folds/length reports crepe folding per length unit (typically inches or centimetres). This

correlates with creping blade wear: new blade produces high folds/length and worn blade

low values. Macro and Micro Crepe indicate folding types categorised as in long and short

wavelengths. Caliper indicates crepe dominant sheet thickness. With new blade macro

and caliper are typically low and micro high. As the blade wears, macro and caliper will

increase and micro decreases.

The system displays the latest captured surface image to operator for visual analysis.

Folds per inch. Upward peaks occur after creping blade change

AGILON LIFTING EQUIPMENT SYSTEM SOLUTION Ahead of Konecranes' official launch of its latest service innovation, Agilon, next month, the world’s leading lifting equipment manufacturer has announced that is has installed and commissioned the system solution within its own parts operation here in the UK. In addition to accommodating some 70% of Konecranes’ existing parts inventory, utilisation of Agilon has also served deliver a key benefit that the materials management solution has the capability of providing, a significant footprint gain. As Paul Nagy, General Manager for Agilon, comments: “Whilst Agilon has the capability of delivering many operational benefits, the fact that it utilises height is set to be one of its prime drivers. Indeed the situation within our own parts operation is a perfect example. Using a 22m x 6m, two-piece system with connecting tunnel that has a height of 5.6m has helped free up more than 30% additional floor space.” The same sentiments are also shared by Konecranes’ head of its UK parts operation, Pamela Severn-Dabbs. “Agilon is helping transform our parts operation, and in many ways; however, the additional floor space that it has freed up is already proving a real benefit. We have a progressive and forward thinking strategy in place for the parts operation, which represents an increasingly significant aspect of Konecranes’ operation here in the UK, and Agilon is set play an instrumental part in this,” she said. Despite the fact that the decision to launch Agilon was only announced at the end of May, it has already attracted significant attention from a number of leading single and multi-site organisations across many industry sectors. As Paul Nagy adds: “Interest in the system has more than exceeded our expectations, and what is particularly pleasing is that this has emanated from a variety of sources, and not just across our existing customer base. Not surprisingly, since the Agilon system was installed at Castle Donington, we have used this opportunity to showcase its real potential in totally transforming the materials management process to a number of potential customers with whom we are now in the advanced stages of negotiation.” Serving to embrace the era of the emerging industrial Internet, Agilon is a patented, fully–automated and modular intelligent solution that is designed to deliver added value to the materials management process. This is achieved by the revolutionary way in which components are managed, stored, picked and replenished, irrespective of end-use application. The Agilon materials management solution consists of a net portal, user access point, a shelving system and one or several robots that travel within the system to pick parts and deliver them quickly and efficiently to one or more service points. The user interface shows the availability of parts or components, whilst also displaying an image of the specific part’s package that is needed. A fully modular system, Agilon can also be supplied with transportation tubes that can be used to connect multiple modular shelf systems, even when located on different floors.

In addition to being able to accommodate parts in original packaging and capable of handling goods or components from matchbox size to 60cm x 40cm x 45cm and weighing up to 25 kilogrammes, Agilon is supplied under a service lease contract that not only includes the modular, upgradeable system, but maintenance and spare parts. “Whilst supplying the system within a service lease contract not only negates significant initial capital or large-scale investment, it ensures that the customer is guaranteed to receive Agilon system updates on a real-time basis, which future proofs their ability to ensure that ongoing production efficiencies are realised,” concludes Paul Nagy. Each Agilon system is designed to meet the specific needs and objectives of each individual customer, the only requirements being suitable premises, internet connectivity and power supply. All Agilon system components are delivered to site in a fully enclosed container, with installation time of a typical 22m x 5.6m primary structure taking just 3 – 5 days. Not surprisingly, Agilon is truly universal in that it can be deployed across the fields of warehousing of production parts, production assembly, internal logistics, e-commerce and retailing. In terms of system robustness, Konecranes claims that over a two-year test period Agilon delivered 99% uptime. Being built around self-aware operating software, the system not only has the capability to monitor its own operating performance, but a Konecranes Global Technical Support (GTS) Team is in place to provide remote back up.

Ceramics in Paper Manufacturing including Advanced and Nano Materials Author- Dr. Mahendra Patel, 420 pages; 32 chapters, ISBN No: 978-81-923542- 4-8. Use of ceramic materials in pulp and paper manufacturing has augmented enormously in the last two decades mainly because of their intrinsic abilities to combat the harsh environments. Advanced and nano ceramics, included in this book, are the new-generation innovative materials to help enhancing energy saving, environmental benefits and material protection. Some of the ceramic materials available now have strength as high as that of metals and the conventional metals and alloys are slowly being replaced by ceramics wherever possible. For example, the overall enhancement brought out in the paper machine, is essentially because of possibility of substitution of the ductile metallic parts by ceramics. The paper machine former, press and dryer are presently provided with special ceramic substances. The paper machinery manufacturers find now the ceramic parts and components to be the appropriate materials to address the harsh environments. Subject of ceramics in paper manufacturing also encompasses the vital issue of recycling the solid wastes, generated from the mills to ceramic products. Pulp and paper mills generate considerable amount of solid waste products namely fibrous sludge, lime sludge, plastic wastes and coal ash. The developments as well as case studies on production of common ceramic materials such as bricks, tiles and cement also form part of the books as these are subject of vital issues for the mills. One of the chapters is specifically devoted to the production of silicon carbide whiskers and other advanced ceramic materials using agro-residues. This book provides valuable imperatives in commissioning of new plant and in selection of materials for machineries. While the maintenance and instrumentation engineers will be most benefitted on reading this book, it will help in bringing down the cost of maintenance and enhance the quality, productivity and efficiency of the mill, thus going to be very important for the papermakers also. Moreover, the techno-commercial information provided in this book on some of the products of the different machinery manufacturers are likely to help promoting their business and improvising their product profile. Among the ceramic products, alumina, silicon carbide, silicon nitride, sialon, zircon, ceramic composites and coatings as well as ceramic tiles, bricks, cement, glass and refractory with thermal spray coating and future of ceramics in pulp and paper manufacturing, make the book quite useful and interesting for both paper mills and machine manufacturers as well ceramics industries.

Materials for Better Productivity in Pulp and Paper Mills: Metals and Polymers Author: Dr. Mahendra Patel; 616 pages; 36 pages; Publ in 2015; ISBN No.978-81-923542-5-5 Foreword by Mr N. Gopalarantam, Chairman, Seshasayee Paper and Boards Ltd, India Words of Congratulation by: Prof. (Dr.) Pradeep Rohatgi; State of Wisconsin and UWM Distinguished Professor and Director of UWM Centre of Composites and Advanced Materials manufacture, University of Wisconsin Milwaukee, U.S.A. The total annual corrosion costs for the pulp, paper and paperboard industry, determined as a fraction of the maintenance cost, is about 6 billion dollars per year. All pulp and paper mills are confronted with corrosion, incurring huge financial losses and productivity. This book provides solutions to the persistent problem of corrosion and help enhancing productivity and profitability of the pulp and paper mills. Selecting machineries etc with appropriate materials is a baffling issue today because the number and quality of materials have increased enormously, for example, there are more than 3000 grades of steels produced today unlike earlier days. This increase has been due to incorporation of iron scraps, which have quite different compositions from one another. Moreover, lot of developments has taken place in technology and material quality by changing the compositions and microstructure. This book presents the compositions and designations of most of these iron and steel grades, employed in construction of machineries etc in pulp and paper as well as in other industries. Similar is the case with the polymer products such as plastic pipes and other parts, rubber, Teflon and fabrics, used in the pulp and paper mills. Polymer, metal and ceramic composites exhibit exceptional qualities and are now used commonly in many parts of the pulp and paper manufacturing, which are discussed extensively in this book. This book reviews the use of conventional materials such as cast iron, carbon and mild steels, alloy steels like 304,304L, 316, 316L, 309 and 310 etc, which are used still in large quantities by the mills and at the same time presents the new and innovative products such as duplex steel, super duplex steel, super steel, super alloys containing Ni, Cu, Co, Mo etc with examples of applications made in some of the mills. New FRP (Fibre reinforced plastic) and Teflon materials, developed recently can replace metals in many areas. This book has been written to provide these multi-disciplinary science and technologies having commercial applications. No earlier book was devoted to such multidisciplinary fields. This book is going to serve for reference to the paper technologists as well as metallurgists in industries, teaching and research organisations. Machinery manufacturers, on reading this book, are certain to come out with better products by replacing the corrosion-prone materials with products without suffering from corrosion. The book is a must for the maintenance department and those interested for starting new pulp and paper industries. Price- US $240+ Cost of dispatch.

C✩iFilm® coating starch: Customer

focussed development of nature-derived binder for coating of Paper and Board The papermaking industry and especially the coated graphical papers have to face various challenges. Europe is an aging society in a mature market showing quite limited growth rates. People’s life style is changing rapidly especially regarding work environment (e.g. home offices and flexibility of people), communication and electronic media as well as social networking and on-line shopping to name a few. For the paper industry these trends led to an increasing consolidation combined with rationalism of companies, their production processes and product portfolio. During the crises in 2008/9 the graphical paper industry was hit heavily and a further decline of about 3% on year’s average is expected for the future. As a result the paper industry in Europe is focusing nowadays on cost optimisation at maintained quality. The trend towards greener and more environmentally sustainable paper making process led to an increased use of starches in coating during the recent years. Papermakers realised that by using classical coating starches, further cost optimisation has reached its boundaries. Some further developments of nature-derived cost effective coating binders remain today possible thanks to a close cooperation between papermaker and starch supplier fully aware of its specific requirements and needs. Technical optimisation We know paper coating requires fine-tuning of multiple parameters to optimise runnability and performance e.g. coating colour rheology, water retention, coater adjustment. It is about taking a holistic view, rather than looking at the effect of starch in isolation. Advanced instrumentation techniques allow us to understand the rheological behaviour of starch, its interactions with other coating colour components and interactions between the coating colours and the base paper. The positive effects seen for the new products were revealed in coating colour formulations by measuring water retention, high shear viscosity as well as intrinsic coating structure.

The full article about the newly developed C*iFilm coating starch will be published in the PITA Annual Review.

Disc Couplings enhance service in high torque applications SKF has launched a range of disc couplings that offer cost-effective, lubrication-free service in medium to high torque applications that require torsional rigidity. The SKF Disc Coupling has a capacity range up to 178kNm in a variety of configurations – including single disc, double disc and spacer for both horizontal and vertical mounting – bringing its benefits to a wide range of applications. “In many applications, the challenge posed by exposure to the elements requires quality parts that continue to operate smoothly,” says David Beggs, SKF Power Transmission Global Technical Manager. “The SKF Disc Coupling offers robust performance, with all-steel machined components that allow for high-speed applications to be handled with ease. With two-plane dynamic balancing, higher speeds are often permissible.” The couplings consist of two hubs and a laminated stainless steel disc pack secured by a series of fitted bolts retained by nylon insert lock nuts. The couplings minimise the need for maintenance because they offer some allowance for misalignment and do not require lubrication. Single disc couplings accommodate angular offset, while double disc pack units with a spacer will allow for angular, parallel or combined offset. The disc pack, or spacer may be removed and re-installed radially, meaning the prime mover and driven machine need not be moved at all. With hub pilot bores to simplify boring to requirements SKF Disc Couplings bring cost-effective high performance to a range of applications and industries, including petro-chemical (direct drive fan drives, pumps and compressors), printing and paper (positioning), plastics, power generation (high speed turbine type drives, alternators, pumps), refrigeration (compressors) and marine. www.skf.co.uk

Industry 4.0 - The future of intelligent paper

production

The total digitisation of production, already called the “fourth industrial revolution” by experts,

is now also making its appearance in Austria. Röchling Leripa Papertech – leading innovator

of wear parts made of plastic for paper machines – was the first company to address the

forward-looking theme of Industry 4.0, and developed a new “smart” product line called

ROBASMART.

Most people are now already familiar with the common term “smart” from mobile phones

(smartphone) and home automation systems (smart living). But even the working world of the

future in Austria, or indeed worldwide, will be defined by the total digitisation of production.

“Smart” machines that are equipped with processors, sensors and wireless connections and

can thus communicate independently with one another will support production and

manufacturing in future. They will organise themselves independently and optimise the flows

and the manufacturing of the products. Thus, stock levels and production levels will be

checked by the smart technology and the production machines will independently re-order

and re-tool themselves. In addition, the reaction to faults or failures can be fast, flexible and

autonomous.

ROBASMART also works according to the “smart” principle. Individual values are read by

means of a mini-server specially developed for the purpose from the wireless devices and

sensors with which the wear parts are equipped, and passed on to the control cabin of the

paper machine. Any corrections that are found to be necessary can then be carried out

manually or fully automatically with the SMART system, which can be switched on and off.

The familiar surface design is retained and is expanded with additional information. The

individual components of the paper machine can be fitted separately and also retrofitted at

any time.

Röchling Leripa has its own in-house centre of excellence equipped with testing machines,

so that the latest findings from research and development can be immediately tested in

realistic conditions that are close to what is encountered in actual practice. The

ROBASMART products were also tested and inspected in this manner before the market

launch.

Apart from the user-friendliness of the system, above all, the safety and economy of the

smart products are very important. Preventive maintenance is not required any more, since

the corresponding notification and warning systems allow action to be taken only when

required, which in turn ensures longer production uptimes. Wear parts are replaced when

necessary, maintenance intervals are controlled exactly and the order planning improved as

a result. The smart products can be employed as decision aids and have a positive effect on

the economic viability of the entire production process. In addition, they contribute

significantly to increasing the paper quality and significantly reduce the consumption of water,

energy and fibre.

PAPERmaking!




A start is being made with the two product lines SMARTROLL and SMARTTABLE. In the

area of the forming section, sealing strips are fitted with sensors that measure the

temperature, wear and noise (SMARTROLL). As regards the press section, dewatering

elements - which can be adjusted horizontally and vertically - are digitised. This facilitates

customised and qualitatively even better production of individual paper grades. All the

information on the new smart product line can be found at www.robasmart.com.

“It is our vision to make many wear parts in the paper machine ‘smart’ in the coming five

years”, says Peter Eckerstorfer, CEO of Röchling Leripa Papertech, about the future of

Industry 4.0 and ROBASMART.

Robasmart – the future of intelligent paper production

The relevant values are acquired from the wear parts, which are

fitted with a large number of sensors, and passed on to the

control cabin of the paper machine. Then, using ROBASMART,

the machine settings can be matched and optimised manually or

fully automatically.

Smartroll – intelligent suction roll system

In the zone of the suction rolls, wear parts with sensors that measure

the temperature, wear, water flow quantity and noise are controlled

through software.

Smarttable – intelligent forming section

In the area of the forming section, dewatering elements are

controlled; they are adjusted manually or automated, horizontally or

vertically, to enhance the paper quality.

Market Research – Hygiene Products Population Growth Drives Demand for Disposable Paper Products Demand for disposable paper products — including toilet tissue, facial tissue, kitchen towels, disposable nappies, baby wipes, sanitary towels, etc. — has been increasing in recent years as the UK’s population has grown in size. Figures from National Statistics reveal that the UK resident population has grown by 14.1% since 1985, to reach 64.6 million in 2014. According to a new Market Report entitled Disposable Paper Products, published by market intelligence provider Key Note, retail sales of disposable paper products in the UK witnessed moderate increases over the past 5 years, rising by 1.5% overall between 2010 and 2014. The recent economic downturn forced hard-pressed consumers to seek better deals on household products and buy items in bulk. This has restricted growth in the disposable paper product market. The disposable tissue products sector — comprising toilet tissues, facial tissues, kitchen towels and baby wipes — accounted for the largest share of disposable paper product sales, at almost three-fifths of the market in 2014, followed by disposable nappies and trainer pants (a quarter) and then sanitary products. Rising awareness among consumers about climate change and environmental degradation has forced more companies to adopt sustainable ethics in their operations. In recent years, an increasing number of disposable paper products made using recycled paper or eco-friendly materials have been launched into the market. For the future, Key Note forecasts the UK market for disposable paper products will grow by a moderate 0.4% in 2015. Key Note’s 2015 Market Report, Disposable Paper Products, analyses the market for disposable tissue products, disposable nappies and sanitary protection products in the UK.

ProTect ensures safe press felt measurement

In the last 24 month Voith has already installed 37 of its

ProTect systems that enable press felt measurements to be taken safely while the machine is

running. Another 32 such systems have been ordered by various customers in Europe and

overseas.

Measurements of the

running press fabrics are

absolutely indispensable

for efficient paper

production. They monitor

the condition of the felts

and from the data

conclusion about

irregularities are drawn, so

that age-related wear or

variations in the felt can be

reliably identified during

operation. Previously,

these measurements could

only be done manually. For

safety reasons, various

paper manufacturers and

governments have recently

started to prohibit these

kinds of manual

measurements.

With ProTect, Voith has developed a solution to replace the manual measuring work

conducted by service personnel. It consists of a stand-alone self-propelled carriage on fixed

cross beams that can accommodate conventional manual measuring devices for safe use

outside the felt run. ProTect can be mounted even in very confined spaces. The system

features a battery and integrated water tank, so it does not have to be connected to a power

or water supply.

In combination with Voith’s OnV FeltView measuring system, ProTect covers the entire

spectrum of felt measurement requirements. OnV FeltView can also be integrated into the

OnView information system.

Protect Your Employees to Protect Your Business New personal protection equipment (PPE) from Crescendo, the PPE 20 and PPE 25, in-ear protection plugs can dramatically reduce employee health problems caused by working in very noisy environments. Twenty percent of the UK population will be affected by hearing problems by 2031, which heralds a multi-billion pound loss to the economy in economic output* and for businesses increased compensation claims. The PPE 20 and PPE 225, reusable and washable, triple flange earplugs, have been developed by Crescendo for industrial, construction and other noisy environments. The design offers the highest level of sound protection normally associated with expensive custom-made in-ear hearing protection. The sound filter technology used ensures a natural sound balance to the wearer, through uniform attenuation. This results in a reduction of sound levels equally across all frequencies, ensuring clear speech and sound recognition is maintained, an essential safety requirement in noisy work places. Designed to be reusable, manufactured in environmentally friendly – 100% organic thermoplastic elastomer (TPE), the earplugs are safe and comfortable for continuous shift working. The replaceable filter design, with its air channel, allows air to circulate in the ear eliminating ‘hot ear’, which can cause irritation and infection. These products are the ideal long term replacement for the millions of disposable one-use foam earplugs sent to landfill each year. The PPE range provides the ultimate universal fit hearing protection product. • The Crescendo PPE 20 reduces sound levels by 20dB (decibel), providing 8 hours

continuous use in any environment up to 105dB – approximately the sound of a jet engine at 1000ft.

• The PPE 25 reduces sound levels by 25dB, making it safe for up to 8 hours continuous use in environments up to 110dB – approximately the sound of a live rock band.

Ready to wear out of the box, with no forming required, Crescendo PPE 20 and PPE 25 are available in two sizes (medium and large). The design helps position the plug correctly within the ear and provides stability and increased retention during extended periods of wear and physical exertion.

No interference with headgear, eyewear or headsets. Compatible with earmuff as dual layer protection in extreme noise environments.

Water resistant carry case

Maintains hygiene and protection when stored.

Passive Operation

No batteries required.

Reusable

Easy to clean, reducing the potential for ear infections.

With its energy savings potential of 50% lower applied energy and lower reject rates than conventional Hydrocyclones, our Celleco Twister Hydrocyclone technology can be a true money saver. TamPulper™ Rotor Upgrade TamPulper™ Rotor Upgrades will improve the operation and capacity of existing pulpers. Most pulper installations have been pushed for additional capacity over time. Upgrades to a more efficient rotor design can improve performance and insure reliable operation. Designed around the principal configuration of pump impeller with vanes on a central rotor core, the TamPulper™ impeller provides high circulation in a pulper vat. Taller vanes at the inner diameter reduce bridging of material on the rotor and provide fluid volume movement to feed the outer portion of the vanes to help generate maximum circulation. The fabricate design allows for custom design for a specific application along with fit on most standard pulpers. TamPulper rotors can supplied as part of a rotor retrofit or as a complete pulping unit upgrade. The upgrades can be combined with other improvements such as high capacity extraction grates and directional vanes to maximize the pulper production. WellDrain® Sector The WellDrain® disc sector covering provides a substantial increase in drainage surface area through its unique corrugated shape. The increased surface area enables both a smaller disc filter for new applications and in many cases a considerable increase in capacity for an existing installation. Retrofitting Welldrain® segments onto an existing disc filter is a cost effective way to increase capacity. In many cases this will provide the increased performance or capacity required with the existing filter, eliminating the need for larger capital investments WellBag™ Sector The WellBag™ disc sector covering provides a substantial increase in drainage surface area through its unique corrugated shape.

Ultrasonic measurement predicts paper performance

ABB, the leading power and automation technology group, is

providing a unique tool using ultrasonic technology that allows

early prediction of paper and board materials performance, while facilitating the optimisation

of key production processes.

The L&W TSO Tester measures Tensile Stiffness Index (TSI) and Tensile Stiffness

Orientation (TSO) properties on machine- or cross-machine profile paper samples cut out

from the jumbo reel. The device works by sending an ultrasonic pulse across the paper and

measuring velocity in eight different directions. The results predict the performance of paper

used in a sheeting process, in a multi-colour printing process, in laser copying machines and

when manufacturing corrugated board. A paper machine using the tester can easily achieve

specifications for compressive, tensile and bursting strength.

Typical trouble-shooting and prevention facilitated by the tool relate to the headbox, press

and drying sections of the manufacturing process. In the headbox, for example, the device

can help manufacturers to identify quickly whether action is required to manage pressure

pulsations or deviating pressure profiles.

The device can also be used to predict runnability in a range of applications. When making

corrugated board, for example, the device enables manufacturers to avoid warping by

ensuring the TSI/TSO measurement of the single face liner matches that of the double

backer. Or, in multicolour printing where the hygro-expansion orientation needs to be

carefully managed, the instrument’s TSO-angle measurement capabilities can help.

“By providing manufacturers timely access to key measurements,” notes Thomas Fürst,

Product Manager, ABB/Lorentzen & Wettre, “papermakers can save on time and raw

materials by catching potential issues early in the production cycle.”

PAPERmaking!




A typical cross-directional measurement is performed within five minutes, and provides

complete information on the full web width, including edges. The TSI and TSO profiles can be

determined at every reel change. Early action can be taken against possible deviations in the

following reel, keeping the TSI and TSO values, as well as any calculated strength

properties, within pre-determined limits.

To use the instrument, a test strip of paper is cut from the reel, using the profile sample cutter

from Lorentzen & Wettre. The strip is attached to the instrument’s feeder and the

measurement sequence is automatically performed by pressing the start button. The

measurement speed is about six seconds per measuring point. Thus, the total time required

for a complete profiling sequence depends on the length of the sample and the distance

between measuring points.

L&W TSO Tester consists of a table-top ultrasonic measuring unit with feeder attachment

and PC software for logging of test results. The colour touchscreen has intuitive menus, user-

friendly interface, and a protective surface for easy cleaning and durability. TSI- and TSO-

values are presented on the touchscreen, either in tabular or graphic form. Results can also

be printed on the built-in printer, on a network printer or exported via Ethernet. The

instrument acts as an FTP-server and test results can be retrieved by an FTP-client. The

complete measuring station can be placed either in the machine control room or in the

laboratory. All results can be stored for further analysis or for transfer to other computers.

UniFilm and UniSize roll covers

The market launch of Voith’s UniFilm and UniSize, two rubber

roll covers for film and size presses, is the start of a new product series. The wish to offer

economic benefits to papermakers played an important role in the development of the Uni

series. For example, the development goal for the UniFilm roll cover was to substantially

extend the metering rod service life.

Voith developed the UniFilm rubber roll cover for use in film presses, while UniSize was

specially optimised for the requirements of puddle size presses. Both roll covers feature a

new polymer matrix and new base layer

structure that ensures maximum bonding

to the roll core. Another new feature is the

integration of an innovative filler system

that creates the very uniform and stable

surface roughness that is crucial to

achieving a high-quality coating.

The UniSize roll cover has better

mechanical properties than standard roll

covers and therefore offers greater

resistance in the event of web breaks. The

new UniFilm cover for applicator rolls impresses with its high abrasion resistance and longer

metering rod service life thanks to micro-lubrication. Extensive trials and test series in

European paper mills have provided proof that metering rod service life is actually extended

thanks to UniFilm. Savings can be up

to EUR 50,000 per year.

CARBOHYDRATE SCIENCE Hydrated fractions of cellulosics probed by infrared spectroscopy coupled with dynamics of deuterium exchange, C. Driemeier et al, Carbohydrate Polymers, 127. A novel method to selectively probe the non-crystalline, hydrated fractions of cellulosic biomass, using time-resolved infrared spectroscopy. The results provide new insights on molecular and group orientation and on hydrogen bonding in hydrated fractions of cellulosic biomass. A morpholinium ionic liquid for cellulose dissolution, D.G. Raut et al, Carbohydrate Polymers, 130. A new ionic solvent, N-allyl-N-methylmorpholinium acetate, was found to dissolve cellulose readily without any pre-processing of native raw material, and without changing the degree of polymerization of the different celluloses after regeneration. COATING Optimization of synthesis and characterization of oxidized starch-graft-poly(styrene-butyl acrylate) latex for paper coating, S. Cheng et al, Starch – Stärke, 67 (5-6). A three-level, four-variable Box-Behnken design was employed to investigate the effects of the concentration of OS, initiator, monomers, and temperature on the graft copolymerization. Application of the OS-g-P(ST-BA) latex as a binder in paper coating improved the gloss, print gloss, and picking resistance of coated paper. NOVEL PRODUCTS Properties of cellulose/Thespesia lampas short fibers bio-composite films, B. Ashok et al, Carbohydrate Polymers, 127. Cellulose was dissolved in pre cooled environment friendly solvent (aq.7% sodium hydroxide+12% urea) and regenerated with 5%H2SO4 as coagulation bath. Using cellulose as matrix and alkali treated short natural fibers extracted from the newly identified Thespesia lampas plant as fillers the green composite films were prepared. The films were found to be non-toxic. The effect of fibre loading on the tensile properties and thermal stability was studied. Enhanced electromechanical performance of bio-based gelatin/glycerin dielectric elastomer by cellulose nanocrystals, N. Ning et al, Carbohydrate Polymers, 130. In this study, a bio-based gelatine/glycerin (GG) elastomer was used as the DE matrix, and Cellulose nanocrystals (CNCs) were used to improve the mechanical strength of GG elastomer. The results showed that CNCs with a large number of hydroxyl groups disrupted the hydrogen bonds between gelatine molecules and formed new stronger hydrogen bonds with gelatine molecules. Hydrophobic cellulose: a material that expands upon drying, W.C. Chen et al, Cellulose, online. Most known materials shrink upon drying and swell upon wetting, a phenomenon known as dry-shrinkage; and thus are characterised by a dry-shrinkage coefficient either equal or greater than zero. Different from conventional materials, sheets of hydrophobic cellulose fibres expand upon drying, which implies that they exhibit dry-expansion. A mechanism for the dry-expansion of this material is proposed.

PACKAGING TECHNOLOGY Preparation and characterization of sodium carboxymethyl cellulose/cotton linter cellulose nanofibril composite films, A.A. Oun & J-W Rhim, Carbohydrate Polymers, 127. Crystalline cellulose nanofibril was used as a filler to reinforce sodium carboxymethyl cellulose film. The composite films have a high potential to be used as an edible coating or packaging films for the extension of shelf life of fresh and minimally processed fruits and vegetables. Effect of the addition order and amylose content on mechanical, barrier and structural properties of films made with starch and montmorillonite, C.A. Romero-Bastida et al, Carbohydrate Polymers, 127. This study considered the effect of amylose content (30% and 70%), montmorillonite fraction (5 and 15%) and preparation method on mechanical and barrier properties of starch/clay nanocomposites prepared by casting. Antimicrobial nanostructured starch based films for packaging, A.S. Abreu et al, Carbohydrate Polymers, 129. Montmorillonite modified with a quaternary ammonium salt C30B/starch nanocomposite (C30B/ST-NC), silver nanoparticles/starch nanocomposite (Ag-NPs/ST-NC) and both silver nanoparticles/C30B/starch nanocomposites (Ag-NPs/C30B/ST-NC) films were produced. Results indicated that the starch films incorporated with C30B and Ag-NPs have potential to be used as packaging nanostructured material. Bio-nanocomposite films reinforced with cellulose nanocrystals: Rheology of film-forming solutions, transparency, water vapor barrier and tensile properties of films, N. El Miri et al, Carbohydrate Polymers, 129. This study was aimed to develop bio-nanocomposite films of carboxymethyl cellulose (CMC)/starch (ST) polysaccharide matrix reinforced with cellulose nanocrystals (CNC) using the solution casting method. The as-produced films exhibited good optical transparency, reduced WVP and enhanced tensile properties, which are the main properties required for packaging applications. Antimicrobial polyethylene wax emulsion and its application on active paper-based packaging material, X. Xu et al, Journal of Applied Polymer Science, 132 (27). Antimicrobial polyethylene wax (PEW) emulsions, prepared by emulsifying polyethylene wax grafted with polyhexamethylene guanidine hydrochloride (PEW-g-PHGH), were used as wet-end additives or coating materials for making hydrophobic and anti-mould paper. Modelling of Migration from Printing Inks on Paper Packaging, Z.-W. Wang et al, Packaging Technology and Science, 28 (4). The migration model of contaminants from inks on paper packaging to food is developed based on the penetration of ink in paper and Fick's diffusion. The printed paper is divided as ink layer and paper layer. The model equation is solved, and the migration expression is obtained by using the method of separation of variables. The Potential of NanoCellulose in the Packaging Field: A Review, F. Li et al, Packaging Technology and Science, 28 (6). Nanocellulose particles can be utilised as fillers, in composites manufacture, as coating and as self-standing thin films. Very few of the several reviews that recently appeared on this topic in the scientific literature, however, summarised the potential of cellulose in nanoform specifically for the packaging field. In the present review, the remarkable chemical and physical properties of nanocellulose are introduced and discussed with specific reference to packaging needs.

PAPERMAKING CHEMISTRY A preparation method of cellulose fiber networks reinforced by glutaraldehyde-treated chitosan, T. Wu & R. Farnood, Cellulose, 22 (3). An eco-friendly polymeric additive was developed to increase the dry and wet strengths of cellulose fibre networks. The surface morphology of cellulose fibres deposited with GA-treated chitosan was examined by scanning electron microscopy. The effects of glutaraldehyde-chitosan treatment on tear resistance and colour properties were also investigated. Biobased polymers and cationic microfibrillated cellulose as retention and drainage aids in papermaking: Comparison between softwood and bagasse pulps, M. Diab et al, Industrial Crops and Products, 72. Water soluble cationic chitosan and surface-modified microfibrillated cellulose were prepared and characterised; both were used with bentonite in order to improve drainage and filler retention in paper handsheets made from softwood and bagasse pulps. Performance was compared with a commercially available cationic polyacrylamide. Preparation and property of waterborne UV-curable chain-extended polyurethane surface sizing agent: Strengthening and waterproofing mechanism for cellulose fiber paper, H. Wang et al, Journal of Applied Polymer Science, 132 (31). Waterborne UV-curable polyurethane (UWPU) dispersions with different hydrophilicity and functionalities were prepared by varying the content of dimethylol butanoic acid and pentaerythritol triacrylate. The obtained UWPU could be directly used as an effective and fast drying surface sizing agent for cellulose fibre paper. Elasto-capillary collapse of circular tubes as a model for cellulosic wood fibres, M. Soleimani et al, Journal of Materials Science, 50 (15). Wood-fibre conformation affects paper properties in various paper-product categories, such as packaging, printing, and absorbents. To quantify this process, the authors theoretically and experimentally investigate deformation of a circular tube under capillary pressure. This elasto-capillary model elucidates the influences of wetting angle, tube-wall flexibility, and hole size on the tube deformation. The results prove that capillarity can collapse the fibre lumen, either partially or completely, depending principally on the fibre-wall flexibility. Preparation and characterization of calcium carbonate–titanium dioxide core–shell (CaCO3@TiO2) nanoparticles and application in the papermaking industry, H. Tao et al, Powder Technology, 283. Carbonization was selected to prepare calcium carbonate, titanium sulphate was the titanium source, and urea was the precipitant to synthesise the target product with the direct precipitation method. The whiteness of the CaCO3@TiO2 filler-containing paper sheet was 73.8%, which is similar to TiO2-incorporated paper (73.16%), and higher by about 3% than pure fibre paper (70.35%). PIGMENTS Fabrication of TiO2/EP super-hydrophobic thin film on filter paper surface, Z. Gao et al, Carbohydrate Polymers, 128. A composite filter paper with super-hydrophobicity was obtained by adhering micro/nano structure of amorphous titanium dioxide on the filter paper surface with modifying low surface energy material. By virtue of the coupling agent, which plays an important part in bonding amorphous titanium dioxide and epoxy resin, the structure of super-hydrophobic thin film on the filter paper surface is extremely stable. This method offers an opportunity to the practical applications of the super-hydrophobic filter paper.

Click chemistry route to covalently link cellulose and clay, P. Yadav et al, Cellulose, 22 (3). An efficient method for covalently linking of cellulose and clay using a click chemistry based strategy is reported. Azide and alkynyl derivatives of silane were synthesized and used for silanization of cellulose and clay respectively. Functionalised cellulose and clay were then coupled using Cu(I) catalyzed azide–alkyne cycloaddition reaction, resulting in a covalent linkage between them. Modification of wollastonite by acid treatment and alkali-induced redeposition for use as papermaking filler, H. Xue et al, Powder Technology, 276. After acid treatment then alkaline deposition, the wollastonite particles were larger, had a higher zeta potential, and were brighter than were those of the original sample. The properties of paper sheets, especially bulk and brightness, in which a Na2SiO3-induced redeposited wollastonite sample was used as the filler were superior to those in which the original wollastonite sample or other alkali-induced redeposited wollastonite samples were used. POWER & ENERGY The changing nature of life cycle assessment, M.C. McManus & C.M. Taylor, Biomass and Bioenergy, online. LCA has evolved from its origins in energy analysis in the 1960s and 70s into a wide ranging tool used to determine impacts of products or systems over several environmental and resource issues. This paper examines LCA's on-going evolution and its use within bioenergy deployment. Changes seen in bioenergy LCA will bleed into other LCA arenas, especially where it is important that a sustainable solution is chosen. Recycling of Paper Mill Biosolids: A Review on Current Practices and Emerging Biorefinery Initiatives, M. Pervaiz & M. Sain, CLEAN – Soil, Air, Water, 43 (6). This review presents an holistic overview on current practices in dealing with paper sludge and their environmental and economic implications. Also presented is a comprehensive discussion on emerging biorefinery trends leading to value-added utilisation of primary, secondary and mixed biosolids originating from effluent treatments plants, especially from paper mill operations. PULP Biochemical evaluation of xylanases from various filamentous fungi and their application for the deinking of ozone treated newspaper pulp, P. Chutani & K.K. Sharma, Carbohydrate Polymers, 127. Filamentous fungi, Aspergillus oryzae MDU-4 was selected for xylanase production. The implementation of ozone treatment in the deinking of newspaper pulp resulted in high crystallinity index (72.1%) and more fibrillar surface. Furthermore, the xylanase treated pulp showed significant improvement in optical properties such as brightness (57.9% ISO) and effective residual ink concentration (211ppm). Production of recycled cellulose fibers from waste paper via ultrasonic wave processing, X. Guo et al, Journal of Applied Polymer Science, 132 (19). The objective of this article was to study the production of recycled cellulose fibres from waste paper using ultrasonic wave processing. The physical and chemical properties of recycled cellulose fibres, such as water absorption, specific surface area and pore characteristics, etc., were investigated with various testing methods. The results indicated that the ultrasonic cavitation effect was feasible for the preparation of the secondary fibres.

TESTING 3D analysis of paper microstructures at the scale of fibres and bonds, C. Marulier et al, Cellulose, 22 (3). The evolution of paper microstructure parameters, such as porosity and fibre orientation, as a function of papermaking conditions, is most often studied at a macroscopic scale. However, modelling the physical and mechanical properties of papers using upscaling approaches requires understanding the deformation micro-mechanisms that are induced by papermaking operations within the structure of paper fibrous networks for individual fibres and fibre-to-fibre bonds. This is addressed here by analysing three-dimensional images of model papers obtained using X-ray microtomography. Microrobotic system for multi-rate measurement of bio-based fibres Z-directional bond strength, S.K. Latifi et al, Journal of Micro-Bio Robotics, online. The core content of this study was micro-testing of microscale objects - an emerging application area for microrobotics. This article reports an in-depth study of a measurement method for experimental evaluation of Z-directional individual fibre-fibre bond strength in multiple loading rates using microrobotics and a Polyvinylidene fluoride film microforce sensor. WASTE & ENVIRONMENT Refractory organic pollutants and toxicity in pulp and paper mill wastewaters, P.C. Lindholm-Lehto et al, Environmental Science and Pollution Research, 22 (9). This review describes medium and high molecular weight organic material found in wastewaters from pulp and paper industry; the aim being to review the pollutants and the analysis methods for their determination, including toxicity testing. Evaluation of metals in the residue of paper sludge after recovery of pulp components using an ionic liquid, J.-H. Jeong et al, Journal of Material Cycles and Waste Management, online. The quantity of sludge produced by the paper industry in Japan in 2011 was estimated to be 27.91 million tons wet weight. This amount is the third largest among all industrial wastes. To explore ways of reusing recovered paper pulp and safely disposing of the residue, the authors investigated the distribution of metals in the process of recovery of pulp from two types of paper sludge using an ionic liquid. Development of green nanocomposites reinforced by cellulose nanofibers extracted from paper sludge, H. Takagi et al, Modern Physics Letters B, Condensed Matter Physics; Statistical Physics; Atomic, Molecular and Optical Physics, 29 (06n07). The purpose of this study was to extract the cellulose nanofibers from waste bio-resources; such as waste newspaper and paper sludge. Furthermore, in order to examine the reinforcing effect of the extracted cellulose nanofibers, fully biodegradable green nanocomposites were fabricated by composing polyvinyl alcohol (PVA) resin with the extracted cellulose nanofibers, which were then subjected to tensile tests. Water Reuse Within the Paper Industry, A. Blanco et al, chapter in The Handbook of Environmental Chemistry, Springer, 2015. Pulp and paper industry is still an intensive water consumer, although fresh water use by this sector has decreased by 90% along the last three decades. This review looks at how sustainable water management has been achieved by following the principle of water fit for use, which has mainly been developed through the optimisation of water circuits, the cascade use of water, the implementation of internal water treatments, the optimal treatment of effluents to be reused, and the use of alternative water sources, such as reclaimed water from municipal wastewater treatment plants.

WOOD PANEL Optimization of Admixture and Three-Layer Particleboard Made from Oil Palm Empty Fruit Bunch and Rubberwood Clones, S.O.Al-E.S. Azry et al, Agricultural Biomass Based Potential Materials, 2015. Two types of particleboards (admixture and three-layer) with different ratios of the fibrous raw materials, were produced. It was found that admixture particleboards showed superior properties compared to three-layer particleboards, and that the optimum ratios of EFB and both rubberwood clones are found to be 1:1 (50 % EFB: 50 % rubberwood). Use of almond shell powder in modification of the physical and mechanical properties of medium density fiberboard, M. Nazerian et al, BioResources Journal, 10 (1). This study evaluated the effects of almond shell powder content as an extender, as well as the effects of varying paraffin contents, temperature, and press time on the properties of medium-density fibreboard. Manufacture of particleboard based on cement bag and castor oil polyurethane resin, J.C.M. Cravo et al, Construction and Building Materials, 87. This study assessed the potential of cement packaging residues from building site wastes to produce particleboards. The results revealed that the packages have a high cement content and low lignin pulp; thus, the packaging of cement becomes an option for the manufacture of particle board. Optimization of press temperature and time for binderless particleboard manufactured from oil palm trunk biomass at different thickness levels, M. Baskarana et al, Materials Today Communications, 3. A set of experiments was designed with two numerical factors including press temperature and time ranging from 160 to 200 °C and from 20 to 30 min, respectively at three target thicknesses, namely 5, 10 and 15 mm. Based on the findings in this work internal bond strength, thickness swelling and water absorption of the panels improved with reduction of the panel thickness. Influence of technological factors on properties of chipboards based on a cardanol-containing polyurethane binder, S.A. Dozhdikov et al, Polymer Science Series D, 8 (2). To study the influence of technological factors upon physico-mechanical characteristics of chipboards containing a cardanol-containing polyurethane adhesive as a binder, a five-factor experiment was carried out twice in accordance with the Box-Wilson central composite design. The calculated optimal conditions for the chipboard pressing process were proven by experimental data.
