1. Abstract
Deze masterproef beschrijft de vrijwillige milieurapportering van bedrijven op hun website.
Specifieke afvalrapportering werd hierbij onderzocht. Er werd bestudeerd of bedrijven
vrijwillig rapporteren over hun afvalbeleid en welke de redenen zijn wanneer ze dit doen. Voor
deze studie werd er gebruik gemaakt van een steekproef van Vlaamse bedrijven uit de
bouw -en voedingssector. Van deze bedrijven werden de gegevens bekomen die zij verplicht
moesten doorgeven aan de Openbare Vlaamse Afvalstoffenmaatschappij. Bijkomende
analyses werden verricht om de mate van de afvalrapportering te achterhalen. Ook de
verschillen tussen de twee sectoren werden geanalyseerd. Resultaten wijzen er op dat het
type afval (gevaarlijk - ongevaarlijk) dat een bedrijf produceert, de sector waarin een bedrijf
actief is en de grootte van een bedrijf de meest doorslaggevende factoren zijn wanneer een
bedrijf moet beslissen om vrijwillig te rapporteren over haar afvalbeleid.

2. Introduction
Over the last decade, environmental reporting has been the subject of much research.
Environmental reporting can be defined as ‘the preparation and provision of information, by
management, for the use of multiple stakeholder groups (internal and external), on the
environmental status and performance of their company or organisation.’ (FEE, 2000, p. 3) Its
objective is to be ‘the provision of information about the environmental impact and
performance of an entity that is useful to stakeholders in assessing their relationship with the
reporting entity.’ (FEE, 2000, p. 9)
Even though, in some countries, companies are required to provide environmental reports to
the country’s authorities, they are never required to make these reports publicly available. In
the last decade, however, the public’s demand for and interest in environmental information
has risen (Bebbington, Gray, and Larranniga, 2000). This rising demand is due to, among others,
environmental disasters caused by companies (Deegan, Rankin, and Vought, 2000). A recent
example of such a disaster is the BP oil spill in the Gulf of Mexico in 2010. Other reasons are
the expansion in environmental regulations, pressure groups’ right to know about social and
environmental effects of a firm’s activities, the increase of environmental risk, the raising
awareness of companies that marketing benefits and reputation advantages can be obtained
by telling the world about beneficial environmental actions… (Dixon, Mousa and Woodhead,
2005). Globalisation is also a factor not to be ignored. Due to globalisation, many companies
expanded, and their impact on the environment in which they operate haven’t remained
unnoticed (White, 1999).
Two main stages can be identified in the ‘corporate environmental movement’ (Jose and Lee,
2007). The early stage can be described as the stage where advantageous environmental
actions of organisations can be explained by the fact that they merely wanted to comply with
legal and regulatory requirements (Li, 2001). In the second stage, companies started to realise
which advantages they could obtain by having a superior environmental performance
(Rosen, 2001).
Since the beginning of the 21st century (Raiborn, Butler and Massoud, 2011), an increasing
number of firms started displaying environmental disclosure in their annual reports on a
voluntary basis, to show their concern with environmental issues. It has been reported that
this is a common phenomenon in non-industrial sectors and in various regions in the world
(KPMG, 2002).
3
This paper will focus on one specific area of environmental reporting by companies, namely
reporting on waste management. The association between mandatory reporting, addressed to
the government, and voluntary reporting, addressed to the public through a corporate website,
of Belgian firms will be analysed.
In this study, the following research question can be formulated: “Do firms make their waste
policy publicly available on their corporate website?” Or stated differently: Do firms make
waste information publicly available, and if they do so, what are the factors influencing the
decision to publicise this information. Different predictors can be identified, such as companies’
environmental performance, the industry in which a company operates and the type of waste
a company is producing. In addition, an analysis on the extent of voluntary waste disclosure is
relevant.

3. Contribution of this Study
Today, the environment is a hotter topic than ever and environmental issues are
much-discussed. Stakeholders ask for more information and transparency on companies’
activities. People want to know if there are any risks in living near factories and they want
companies to communicate about their impact on the environment and public health.
Through the years, firms have begun to understand the need and advantages of
communicating about environmental responsibility. Besides the general public’s demand, it
happens more and more that financial organisations partially base their decisions to grant
credits on a company’s environmental performance. Furthermore, governments sometimes
need environmental information when giving out grants (FEE, 2000). Therefore, all this
information needs to be easily accessible.
The data about mandatory waste reporting used in this study, were obtained from a
government institution. This institution collected the information from Flemish companies. As
the companies needed to gather the information to hand it on to the government anyway, it is
interesting to see if they will make the small step to communicate this information to the
public in an attempt to increase their transparency.
There have been many studies about general environmental reporting. However, specific
studies on waste management disclosure have, to our knowledge, never been done. Studying
one specific area of environmental reporting is relevant to find out to which extent companies
will report about their environmental impact. Will they give a condensed overview about
environmental management in general or will they go into detail about every existing aspect,
such as waste management, which will be analysed in this paper, water management, energy
management ...

4. Background and Literature Review
4.1. Mandatory and Voluntary Environmental Disclosure in Belgium
In Belgium, Flanders in particular, companies have many information obligations towards the
government with regard to environmental performance. Through the ‘Integraal
Milieujaarverslag’1 (IMJV) companies have to report about their environmental performance.
The IMJV consists of five forms. Each form treats a different subject such as air pollution,
energy, water and waste. Different authorities are responsible for each form. This study will
focus on the mandatory reporting of waste. It is the ‘Openbare Afvalstoffenmaatschappij’2
(OVAM) which attends to this specific form. Every year, selected companies need to report on
the amounts of every kind of waste they have produced. After collecting all waste data, OVAM
processes all this information and can tune Flanders’ waste policy in on the results (OVAM,
2011). The information collected by OVAM is not publicly available. Hence, stakeholders can’t
use these reports to analyse the environmental performance of companies.
Public environmental disclosure is entirely voluntary in Belgium. Companies can disclose
environmental information via their annual report, CSR 3 reports or a stand-alone
environmental report. Companies can publicise a hard copy version and/or add an online
version to their corporate website. Reasons to decide to disclose environmental information
on a voluntary basis are various. Section 4.3.2. will give a detailed account on this matter.
4.2 Fundamental Theories
In this study, an attempt is made to clarify the presence of voluntary environmental reporting
on waste management with the use of 2 opposing theories, namely the voluntary disclosure
theory (Dye, 2001) and the legitimacy theory (e.g., Patten, 2002). The voluntary disclosure
theory states that there is a positive association between environmental performance and the
level of voluntary environmental disclosure (VED). The statement is based on the fact that
superior environmental performers might want to inform their stakeholders of their valuable
performance to differentiate themselves from poorly-performing firms. Although many studies
1 The ‘Integraal Milieujaarverslag’ (IMJV) is an integrated annual report which combines all the
environmental obligations firms are subjected to. <http://milieujaarverslag.milieuinfo.be/> 2 The ‘Openbare Afvalstoffenmaatschappij’ (OVAM) is a Flemish public corporation that works on issues
of waste management and soil remediation. <http://www.ovam.be/jahia/Jahia/pid/973> 3 Corporate Social Responsiblity
6
have proven this theory to be true (e.g., Clarkson, Li, Richardson and Vasvari, 2008), studies on
the legitimacy theory (e.g., Cho, Patten and Roberts, 2006) have contradicted these results.
The legitimacy theory claims a negative association exists between environmental
performance and the level of voluntary environmental disclosure. This conclusion is based on
the increasing attention to environmental performance results and, consequently, the
pressure inferior performers are experiencing. As a reaction, firms performing below standards
may disclose even more than is requested to try to soothe their stakeholders’ worries (Raiborn
et al., 2011). This way, stakeholders will focus on the company’s positive actions and their
attention will be diverted from the bad news. This can be an attempt to improve the
company’s reputation and change the stakeholders’ expectations (Clarkson et al., 2008).
Clarkson et al. (2008) claim that these mixed results are due to the different utility of both
theories: ‘The legitimacy theory is useful in predicting what is disclosed, but inaccurate in
predicting how much is disclosed’ (Dawkins and Fraas, 2011, p.385)). In this study, it will be
investigated whether the voluntary disclosure theory and the legitimacy theory can be applied
on waste reporting and if so, which theory of the two is applicable on this research.
4.3. Prior Research on Voluntary Environmental Reporting
4.3.1. Voluntary Environmental Disclosure on the Internet
Over time, most companies included environmental information with the firm’s annual report
(Sumiani, Halsinda and Lehman, 2007) or they publicised a separate environmental report
(Morhardt, 2010). Over the last few years, however, there has been an increasing trend in
environmental disclosure on the firms’ corporate website. Between 2000 and 2008, there was
a rise of more than 15% of firms that disclosed environmental information on their website.
The internet has become an important tool to companies to inform their stakeholders about
their activities to improve their impact on the environment (Razeed, 2010). The use of
websites for environmental disclosure may imply some disadvantages (occurrence of technical
problems, uncertainties about the information being up to date …), but these don’t weigh up
against the many advantages the internet provides. Some examples are the lower costs that
are needed to report on the internet, the ability to reach a large group of stakeholders, the
ease of use … (Scott and Jackson, 2002). Companies report on their environmental policies in
many different ways. Some give a short and simple overview, others give a much more
detailed and lengthy statement (Jose et al., 2007). The subjects of these reports are
widespread. The most common topics are the company’s environmental policy, which
environmental targets the company has reached and the follow-up of objectives that are still
7
in place, the activities the company has established to improve its environmental behaviour,
whether (internal or external) environmental audits have been undertook … (Stray, 2008; Jose
et al., 2006; Tagesson, Blank, Broberg, and Collin, 2009)
4.3.2. Reasons for Voluntary Environmental Disclosure
In contrast with mandatory reporting, that is referred to as something annoying companies
must do, voluntary reporting is perceived to be much more acceptable (Gilges, 1991). Unless
companies are participating with the EMAS4 regulation, which requires companies to publicly
provide environmental information to their stakeholders5, firms can disclose environmental
information to the public on an entirely voluntary basis. In this respect, it has been found that
Western European countries and Japan are providing more voluntary environmental disclosure
than the United States. Moreover, besides the expansion in quantity, VED in European
countries has also increased in quality. This is due to the fact that European firms experience,
more than in the U.S., VED to be a value-added tool (KPMG, 1999). Another finding is that
industries that are identified to be more environmentally sensitive, such as manufacturing
industries, deliver more environmental disclosure than less environmentally sensitive
industries, such as the finance or media sector (Jose et al., 2007). This is the result of
companies from environmentally sensitive industries wanting to appease their stakeholders
and show them that, although they’re perceived to be big polluters, they’re doing everything
to minimise the pollution as much as possible. This can also have a positive outcome with
regard to their reputation (Jenkins and Yakovleva, 2006).
Hence, the reasons to supply environmental disclosure are clearly scattered. To many
companies, environmental disclosure is a way to show that they take their stakeholders’
concerns into account and that they take considerate actions to preserve the environment.
Furthermore, public disclosure is a mean to indicate which targets they have been able to
achieve and to give the opportunity to stakeholders to make a reliable analysis of companies
after which they can be ranked (KPMG, 1999). This shows that, when being environmentally
responsible, companies are not only driven by laws and regulations, but also by non-legal
factors, such as ethical values (Jose et al., 2007).
4 Eco-Management and Audit Scheme: an EU management tool for companies and other organisations
to evaluate, report and improve their environmental performance. Companies take part in this scheme on an entirely voluntary basis. <http://ec.europa.eu/environment/emas/index_en.htm> 5 Regulation (EC) No 1221/2009 of the European Parliament and of the Council of 25 November 2009 on
the voluntary participation by organisations in a Community eco-management and audit scheme (EMAS), repealing Regulation (EC) No 761/2001 and Commission Decisions 2001/681/EC and 2006/193/EC
8
On the other hand, environmental reports that are voluntarily disclosed need to be analysed
with some caution. Some reports may not be that accurate. Companies could report about
activities they are not executing in reality or it could be possible that companies only report
positive information while having a lot of negative affairs going on as well. It is clear that
companies would be reluctant to disclose information that could jeopardise their reputation
(Dixon et al., 2005). In the literature, this phenomenon is called ‘greenwash’. Lyon and
Maxwell (2011) define greenwash as the ‘selective disclosure of positive information about a
company’s environmental or social performance, without full disclosure of negative
information on these dimensions, so as to create an overly positive corporate image.’ (Lyon
and Maxwell, 2011, p. 9)
4.4.3. Voluntary Environmental Disclosure Frameworks
Even though voluntary environmental disclosure has grown, there is no consensus on how
companies should report about environmental reporting. One globally accepted framework
that guides companies in doing so, doesn’t exist. However, over the years, several
organisations have taken initiatives in an attempt to elucidate the matter. Some examples are
The British Standard, The International Organisation for Standardisation (ISO), The
Copenhagen Charter, The Global Reporting Initiative Guidelines (GRI)… Nevertheless, these
initiatives don’t offer generally accepted rules concerning the abundance of issues, such as the
content of environmental reports, how environmental data should be collected and analysed,
how the verification should be done… (Dixon et al., 2005). In August 2000, ‘De Tijd’ reported
that the FEE6 concluded that voluntary environmental reports needed much improvement and
that because of the lack of globally accepted guidelines, there was a gap between ideal
reporting and reality. As a reaction, the FEE had publicised a paper (‘Towards a generally
accepted framework for environmental reporting’) in July 2000 (Barrezeele, 2000). This paper
proposed a general framework that could be applied by every company. Yet, to this day,
companies can still choose their own method of reporting. Nevertheless, reporting
environmental information in accordance with praised initiatives as mentioned above, will
increase the report’s credibility (Tagesson et al., 2009). This explains the growing popularity of
external certifications such as ISO 14001 and EMAS. What’s more, when companies follow a
clear and understandable pattern, it will be easier for stakeholders to consult the reports.
Never-ending and elaborate texts are often perceived as irrelevant and will hardly ever be

9
analysed (Raiborn et al., 2011). To be efficient an environmental report should meet a certain
number of characteristics: ‘First and foremost, the information must be understandable to
‘reasonable astute’ readers such that they may use it in making decisions regarding desired
outcome objectives. The information must also be relevant, reported in a timely manner, and
provide users with information that will help them confirm past decisions or make decisions
about the future. Simultaneously, the information must be reliable by truthfully representing
occurrences in an unbiased and verifiable manner. Information should be reported
consistently from period to period, so that users may make comparisons between periods for
the reporting entity.’ (Raiborn et al., 2011, p. 429)
4.5. Hypotheses
After extensive literature research, it is now clear that there are quite a lot of motives why
companies decide to disclose environmental information publicly. To our knowledge, research
on reasons to disclose voluntarily about a company’s waste policy in particular, has never been
done. In line with this paper’s research question, the intent of the study is to seek the factors
that influence the voluntary disclosure of waste information and management. To this end
four hypotheses are formulated, based on the general environmental reporting literature.
4.5.1. Hypothesis 1
Razeed (2010) notes that, even though companies use the internet for environmental
disclosure, the level of disclosure stays quite low. CSR reporting is done extensively, but
companies won’t include more detailed information about the different aspects. Therefore, it
can be assumed that companies will often make a general statement about their
environmental position and maybe mention certificates they have obtained as a result of good
environmental performance. However, the corporate websites are not used to provide a more
thorough covering of the matter. For this reason, it can be supposed that a separate section
about waste won’t be presented a lot. This was already confirmed after a first, brief
observation of the data which revealed a very small number of firms disclosing about waste on
their corporate website.
Hypothesis 1: In general, firms do not voluntarily report about waste policy on their corporate
website.
10
4.5.2. Hypothesis 2
Based on the legitimacy theory, that states that companies with an unfavourable
environmental performance disclose more than superior performers, it can be deduced that
companies with a high level of waste production are disclosing more environmental
information (Patten, 2002). Those companies are scrutinised with much more attention by
their stakeholders and through environmental disclosure, firms could attenuate stakeholders’
concerns and change their perception about the company’s performance
(Clarckson et al., 2008).
Hypothesis 2: Companies that are disclosing have a worse environmental performance than
companies which are not disclosing.
Or stated differently, the chance of disclosure on waste policy on the corporate website is
linked with a company’s environmental performance.
4.5.3. Hypothesis 3
In general, people want to know if companies in their neighbourhood could be responsible for
any negative consequences to their health. Examples of dangerous waste are asbestos, acids,
oil… Companies could react to this, by ensuring their neighbours they have a well-developed
waste policy to make sure that none of these materials can harm them. Hence, waste policy
reporting can depend on the level of dangerous and safe waste a company produces.
Hypothesis 3: Waste reporting on corporate websites depends on the type of waste firms
produce.
4.5.4. Hypothesis 4
The development of one extra hypothesis is relevant to this study. As this research clearly
analyses the behaviour of two different industries, it can be interesting to study how industry
membership can influence environmental reporting. As stated earlier, according to previous
research (Adams, Hill and Roberts, 1998; Cowen, Ferreri and Parker, 1987), corporations in
environmentally sensitive industries disclose much more environmental information than
corporations operating in less environmentally sensitive industries. In Flanders, the
construction industry produced about 41% of the total volume of waste in 2008. The food
industry produced 8% of this total volume (OVAM, 2010). In se, the construction sector isn’t a
much more environmentally sensitive industry than the food industry is, but in Belgium there
are about 16 times more firms in the construction industry than in the food industry
11
(FOD Economie, 2011, Confederatie Bouw, 2010). This explains the high volume of waste
produced in the construction sector. That’s why this industry could be perceived to be much
more environmentally sensitive by the public, than the food industry. As a conclusion,
voluntary waste reporting could be of a higher level in the construction industry than in the
food industry. However, as the construction industry isn’t explicitly defined as being an
environmentally sensitive industry, we don’t really expect this theory to be applicable in this
study.
On the other hand, firms in the food industry produce other types of waste than those in the
construction industry. Firms in the construction industry may not want to high-lighten the fact
that they produce dangerous and poisonous waste. Therefore, it is possible they wouldn’t
voluntarily mention anything about a waste policy on their website to not attract more
attention on the subject. Since minimal chemicals and other pollutants are used in food
manufacture (Darlington, Staikos, and Rahimifard, 2009), wastes in the food industry are
considered to be much safer and not that harmful to general health. Firms in this industry
might want to emphasise this fact to assure their customers about their products’ quality.
Disclosure about waste information could be a good tool to do this.
At last, in the different industries, different standards are set. Awards, fines, regulations … are
specific for each industry. Therefore, firms of the separate sectors might behave differently
according to the requirements of the sector in which it operates (Aerts et al., 2006).
Consistent with this discussion, it can be concluded that there might be a relationship between
industry membership and waste disclosure. After a brief observation of the data and keeping
in mind the fact both industries aren’t that different when it comes to be environmental
sensitiveness, a negative association is set. As in this study, industry is identified by a dummy
variable (1 = construction industry, 0 = food industry), a negative relationship would mean that
firms in the food industry, report more about their waste policy than firms in the construction
industry.
Hypothesis 4: There is a negative relationship between the industry in which a firm operates
and waste disclosure on its corporate website.

5. Research Methodology
5.1. Data Collection
In this study, a collection of both mandatory and voluntary information has been made of firms
in the construction and food industry. These two industries were chosen because they’re the
industries that produce the most waste (OVAM, 2010). In Belgium, the food industry contained
about 5100 companies and there were about 82 660 companies in the construction industry in
2009 (FOD Economie, 2011, Confederatie Bouw, 2010). The mandatory data was acquired
from OVAM. Waste information of a sample of 567 companies, was obtained from the year
20097, 265 firms in the food industry and 302 firms in the construction industry.
For each company in the sample, an amount of every single type of waste it produced, was
given. Overall, 195 types of waste in the food industry and 152 types of waste in the
construction industry, were identified. To make a clear and more valuable distinction between
all those types of waste, the waste was subdivided into two categories. Dangerous types of
waste were classified in the first category (72 types in the construction industry/80 in the food
industry), safe types of waste were classified in the second category (80 in the construction
industry/116 in the food industry). The safety of a type of waste has been determined based
on the list of waste products publicised in the VLAREA8. This list is placed at the public’s
disposal and can be consulted freely. According to the VLAREA, dangerous waste is defined as
products that can be exceptionally harmful to humans and the environment or materials that
need to be processed in special establishments.
As for the voluntary disclosure, the corporate website of the companies were checked. The
choice of using website was easily made. Firstly, it is the easiest tool for companies to disclose
environmental information and from earlier studies it has become clear that many companies
7 OVAM used the following method to set their sample: A specific parameter was determined (it wasn’t
permitted to publicise the method used to determine this parameter). This parameter estimates the maximum number of firms to be questioned. This way a percentage is assessed to each sector and employee dimension (=number of employees within a company), and the number of firms to be assigned to communicate their waste production can be known. Every firm from the 2 biggest dimensions were assigned and the percentage declines as the dimension decreases. After this, producers are randomly picked until the maximum number of firms was reached. 8 VLAREA: ‘Vlaams Reglement voor Afvalvoorkoming en –beheer’. This is the Flemish regulation on waste
prevention and management. It is part of the Flemish environmental law and gives an overview of all the types of waste companies can report about. <http://navigator.emis.vito.be/milnav-consult/>
13
use their website to communicate about their environmental behaviour (Morhardt, 2010).
Secondly, it is the least time consuming way to gather the information needed in this research.
First, for each company the existence of a corporate website was checked. This was done in
January and February 2012. After this check-up, companies that didn’t have a functioning
website, companies that were closed or had gone bankrupt between 2009 and 2012 and
companies that had changed nationalities due to a take-over were deleted from the database.
This resulted into a final sample of 227 companies in the construction industry and 218
companies in the food industry. Finally, the websites of each company within this data base
was controlled in order to search for disclosure of any information about waste.
This is an extensive data collection which will raise the reliability of the results.

5.2. Empirical Model
In order to test the hypotheses, a general linear model is constructed9. To this end, a
regression equation is formulated10.
VED = β0 + β1 EP + β2 DANW + β3 SAFW + β4 IND + β5 AGE + β6 SIZE + β7 FIN_PER + µ
9 In order to obtain more statistically significant results, the most extreme outliers of all the variables
were removed from the data set. 10
Besides these main variables shown in the equation, some other variables will be constructed throughout the study. Below, these auxiliary variables will be displayed in italics.

5.2.1. Dependent Variable
VED: Voluntary environmental disclosure about waste on the corporate website as of January
and February 2012. The presence of voluntary waste disclosure is measured by a dummy
variable. 1 meaning there is some waste information disclosed on the corporate website, 0
meaning there is no waste information whatsoever disclosed on the corporate website.
VED_DEGREE: When waste information is disclosed, the extent with which this is done is
measured with a coding scale designed by Cormier and Magnan (2003).
‘CER11 content is rated in terms of information quality level, with a score of three (3) for an
item described in monetary or quantitative terms, two (2) when an item is described
qualitatively but in specific terms, one (1) for an item discussed in general, indicative terms
and zero (0) when there is no mention of an item.’ (Cormier and Magnan, 2003, p. 49)
In this study, this method is applied on waste reporting. In appendix II, an overview of all the
disclosed waste information is given with their appropriate score.
While other studies have used word/page counts (e.g., Campbell, Craven and Shrives, 2003),
presence of topics/items (e.g., Cormier et al., 2003) or a combination of both (e.g., Wiseman,
1982), a coding scale is found to be more relevant in this study. After a first observation of
waste disclosure on corporate websites, it became clear that if firms disclosed waste
information, they would do it either in a very compressed manner or in a very elaborate
manner. In this situation, it is preferred to use a coding scale in order to both detect the
presence of waste disclosure and rate the value and quality of the disclosure made by a firm
(Aerts, Cormier and Magnan, 2008).
5.2.2. Explanatory Variables
EP: Environmental performance per company, concerning waste production. To measure the
environmental performance, a proxy was constructed by dividing the total volume of waste of
each company by its number of employees. Companies having a low score are good
environmental performers, companies with a high score are bad performers.
DUMMY_EP: The degree of environmental performance. 1 meaning a company has a bad
environmental performance, 0 meaning a company has a good environmental performance.
To construct this dummy, EP was divided into two groups. Companies having an environmental
11 Corporate Environmental Reporting
15
performance score less than 10 were identified as being good performers, companies with an
environmental performance score higher than 10 were identified as being bad performers.
DANW: The total volume of dangerous waste per company. This is calculated by adding the
volume of all the different types of waste in the first category, produced by a company. The
unit of measurement is tonne.
DUMMY_DANW: The presence of dangerous waste in a company’s waste production. As more
than 90 % of the companies produced very little or no dangerous waste, a dummy variable was
constructed. 0 meaning a company produced little or no dangerous waste, 1 meaning a
company produced dangerous waste. The limit between the two values (0-1) was set on 25
tonne.
SAFW: The total volume of safe waste per company. This is calculated by adding the volume of
all the different types of waste in the second category, produced by a company. The unit of
measurement is tonne. As the total volume of safe waste was highly skewed, a log-
transformation (LN) was employed on this variable to flatten the distribution.
IND: The industry in which a company operates. As this study merely analyses 2 industries, this
characteristic was measured by a dummy variable. Companies in the construction industry are
given the value of 1, companies in the food industry are given the value of 0.
5.2.3. Control Variables
In this study, control variables are in order because from previous research, it became clear
that some characteristics can’t be ignored when analysing environmental disclosure. If ignored,
results could be biased. Three control variables were taken up. Age, size and financial
performance seemed, after thoroughly analysing existing literature, to be most relevant
(Clarckson et al., 2008; Cormier et al., 2003; Tagesson et al., 2009). Media visibility, which gives
companies an incentive to perform above average, is also a relevant variable (Cormier et al.,
2003). However, data collection concerning this variable is very time consuming and therefore
media visibility couldn’t be identified as an extra control variable. Another indicator that could
predict VED, is the presence of some sort of external certification such as an ISO 14001
certificate (Sumiani et al., 2007). However, the only way of verifying the existence of such
certifications in a company, would be to interview each company one by one. Considering the
extension of the employed data base, this was practically impossible.
16
AGE: The age of a company. In order to know the age, the founding date of each company was
looked up in the Belfirst Database.
SIZE: The size of each company. This variable is proxied by the number of employees employed
in the company. In order to simplify the interpretation, 9 dimensions were created12 in which
the number of employees were classified:
1: 1-4 (or no employees)
2: 5-9
3: 10-19
4: 20-49
5: 50-99
6: 100-199
7: 200-499
8: 500-999
9: >1000
FIN_PER: The financial performance per company. This variable is proxied by the return on
capital employed (ROC) which was found using the Belfirst Database for each company. ROC
was chosen as this was the parameter that gave the least missing values for this sample.
(ROC =
)
DUMMY_FIN_PER: The financial performance per company, remodelled into a dummy variable.
Companies with a negative ROC are given the value 0, companies with a positive ROC are given
the value 1.
12 These dimensions were created by OVAM and were communicated as such.

Figure 2 shows a first sign that companies in the food industry disclose more often on waste
policy than companies in the construction industry.
Figure 3: Total Volume of Different Types of Waste
The figure above shows us that the volume of safe waste is much bigger than the volume of
dangerous waste. The following graph confirms this finding. It states that only 10 % of all
companies in the database produce dangerous waste.

Figure 5: Number of Companies per Employee Dimension
From figure 5, we can conclude that a majority of the companies in this data base are small or
medium sized. This reflects the typical Belgian scenery. About 44 % of the companies in this
data base are rather small, having less than 50 employees. 39 % of the companies employ
between 50 and 200 employees, being medium sized. Only 17 % can be identified as big
companies.
Some extra graphs illustrate which specific types of waste the two main categories, safe waste
and dangerous waste, contain. As these types are different in the separate industries, multiple
graphs are constructed so that everything remains clear. These additional graphs are

6.2. Covariance Analysis
A covariance analysis gives us a first look of what we may expect after elaborate testing of the
data base. In order to test the hypotheses, we compute two different correlation tables
(appendix III). One table without using the dummy variables, in another table we do include
the dummy variables.
From those tables, we can conclude that VED is correlated (on a 0.05 level of significance) with
the total volume of safe waste, the presence of dangerous waste, industry and size.
Environmental performance and industry are also correlated separately with dangerous waste
and safe waste. This isn’t surprising as the environmental performance of a company logically
depends on the amount of safe and dangerous waste it produces. The type of waste is also a
result of the industry in which a company operates, as described in section 4.5.4., giving the
introduction to hypothesis 4.
There are some correlations between other variables as well. The correlation between size and
safe waste is the highest with a coefficient of 0.66. This is understandable as bigger companies
will consequently produce a higher volume of waste. Other correlations appearing in this table
aren’t as problematic as their correlation coefficient never exceeds 0.35.
6.3. Results of the Hypotheses
6.3.1. Hypothesis 1
Hypothesis 1: In general, firms do not voluntarily report about waste policy on their corporate
website.
Descriptive statistics about the presence of waste disclosure on companies’ corporate websites
give a first indicator on the results we might expect. From the figure below, it is quite clear that,
overall, companies do not make waste information publicly available.
22
Figure 2: Firms with VED presence per Industry
A binomial test confirms our expectations arisen from the descriptive statistics. The hypothesis
of equality is rejected on a 0.05 level of significance (p-value = 0.000). This means that the two
categories of VED (1 and 0) don’t occur with probabilities of 0.5 and 0.5.
6.3.2. Hypothesis 2
Hypothesis 2: Companies that are disclosing have a worse environmental performance than
companies which are not disclosing.
Or stated differently, the chance of disclosure on waste policy on the corporate website is
linked with a company’s environmental performance.
In order to test hypothesis 2, a test of equality was run. We considered the companies that
disclosed and those that didn’t as two separate groups so that the mean of the environmental
performance of both groups could be compared. It is clear from table 2, that these means are
not statistically different (P-Value = 0.455). This means that the environmental performance
don’t significantly differ between the groups. As a result, hypothesis 2 needs to be rejected as,
in this case, there is no clear relationship between environmental performance and waste
disclosure.

6.3.3. Hypothesis 3
Hypothesis 3: Waste reporting on corporate websites depends on the type of waste that firms
produce.
To test this hypothesis, first of all, a 2x2 cross-table with VED and DUMMY_DANW was
computed. This could allow us to find out if there was an association between VED and the
mere presence of dangerous waste in a company. By running a Chi-square test simultaneously,
evidence was given that the results in the cross-table were statistically significant (P-Value of
0.009 on a 0.05 level of significance).

Table 3: VED * DUMMY_DANW Cross-tab
From this cross-table, we can decide that companies producing no dangerous waste disclose
more often than companies which do produce dangerous waste (80,7 % VS 19,3 %). However,
when running a regression analysis (Table 4), including more explanatory variables, producing
dangerous waste does seem to have an influencing effect. This can be explained due to the
inclusion of these independent and control variables which, through a regression analysis, give
a more valuable and overall picture of the matter. A cross-table can, at least in this case,
reflect an image that seems too limited.

Computing another regression analysis, which takes the total volume of dangerous waste a
company produces into account instead of the fact of simply producing dangerous waste, is
interesting. From this additional regression analysis, it becomes clear that apparently,
disclosing waste information’s not a question of producing a greater volume of dangerous
waste. The mere fact of producing dangerous waste is enough for companies to disclose waste
information.

As for the safe waste, we use a continuous variable, which represents the volume of safe
waste produced by a company. A t-test for equality states that the mean of the volume of safe
waste in the un-disclosing group is statistically different from the mean of the volume in the
disclosing group. The mean in the un-disclosing group is significantly lower than the one in the
disclosing group. This means that the disclosing group produces more safe waste than the
other group. We can hereby conclude that the produce of safe waste has a significant
influence on VED.

From the regression table below, it is also clear that the produce of safe waste has a bigger
influence on VED than the produce of dangerous waste. We can conclude this due to the fact
that the safe waste coefficient is much more significant than the dangerous waste coefficient
(0.028 versus 0.07).

Hence, we can accept hypothesis 3. The type of waste a firm produces does have an decisive
influence on VED.
6.3.4. Hypothesis 4
Hypothesis 4: There is a negative relationship between the industry in which a firm operates
and waste disclosure on its corporate website.
To test this hypothesis, a 2x2 cross-table with the variables VED and IND was computed. This
could allow us to find out if there is an association between the presence of voluntary waste
disclosure on corporate websites and the industries in which companies operate. By running a
Chi-square test simultaneously, evidence was given that the results in the cross-table were
statistically significant (P-Value of 0.002 on a 0.05 level of significance).

From the companies that are disclosing, 68.4% are companies from the food industry against
only 31.6% from the construction industry. Therefore, hypothesis 4 can be considered to be
true; there is a relationship between the industry in which a company operates and its
26
disclosure status. Moreover, in this case it is a negative association as there is more reporting
in the food industry than in the construction industry.
6.3.5. General Regression Analysis
Running a general regression, including all the explanatory and control variables into one
analysis, is a very efficient manner to have an overall view of the matter. This way, it can be
proven that the components which seemed to be influencing from the earlier hypotheses
analyses, keep having this effect when other relevant factors are introduced into the same
model. With this regression analysis, we can also find out if other elements have an influencing
effect on companies’ decision to voluntarily disclose waste information.

As we can see, the results from the hypotheses analyses are supported by both regression
analyses. This gives us a less biased and more valuable view of this study. This regression also
reveals the effect of the control variable ‘Size’. It concludes that the bigger the company is, the
greater the chance of having waste information present on a company’s corporate website.

7. Additional Analyses
During the research for this study, we have found some additional interesting phenomena,
which we hadn’t predicted when starting this paper. Therefore, some additional analyses are
in order.
7.1. Additional Problem Statement 1
Previous research (e.g. Aerts et al., 2008), has proven that the extent with which a company
discloses environmental information has, like the presence of VED, many causes. As the degree
of waste information on corporate websites can clearly be identified in this study, it is
interesting to try and find those influencing factors. The following problem statement is
identified:
What are the factors influencing the degree with which companies report on waste policy on
their corporate websites?
7.1.1. Descriptive Statistics
In order to solve this problem, only the companies that report on waste policy on their
corporate websites were selected. The extent of the disclosures was identified for each of the
companies.

Figure 10: The extend of VED per Industry
Figure 10 represents the extent of VED on the corporate websites in de food and construction
industry. The scores refer to the degree of VED, their meaning are explained in section 5.2.1.
As there is a higher frequency of company with a VED score of 1 in the construction industry
than in the food industry, the graph gives a first sign that companies in the former industry
report in a less extensive way than companies operating in the latter. Moreover, there are a
higher number of food companies with a VED score of 2 or 3, which indicates a more extensive
way of disclosing waste information in the food industry.
7.1.2. Covariance Analysis

analysis can be found. There are only a few correlations between some independent variable,

but these are not problematic (correlation coefficient < 0.6). The table doesn’t identify any
correlation between the dependent variable and the explanatory variables.
A correlation table (appendix IV), including dummy variables, does reveal some correlations
between the dependent variable and the explanatory variables. As VED_DEGREE correlates
with both being a good or bad performer and with having a positive or negative ROC, this
might give a first indication that these are both factors that have an effect on the degree with
which companies disclose waste information.
7.1.3. Results
To solve this additional problem, a distinction is made between various analyses including
dummy variables and one analysis without using dummy variables.
When working with dummy variables, ANOVA tests can be used to compare means of the
different groups. Each dummy variable from our data set can be placed opposite the degree of
VED on corporate websites.
In this data set, four dummy variables can be identified, making four different ANOVA tests
possible. In what follows, a description of each tested variable is given.
DUMMY_EP N Mean P-Value
VED_DEGREE 0 29 2.21 0.001(a)
1 16 1.56 Table 9: ANOVA VED_DEGREE * DUMMY_EP
(a) Significant on a 0.01 level of significance
This ANOVA test (table 9) reveals that the means of the good and bad environmental
performance of companies do significantly differ (P-Value = 0.001 on a 5 % level of
significance). According to the results, the group having a good environmental performance
score (DUMMY_EP = 0), report in a more extensive way than companies being identified to be
bad environmental performers. Therefore, it’s clear that having a good or bad score on
environmental performance has a decisive influence on the degree with which companies
report.
DUMMY_DANW N Mean P-Value
VED_DEGREE 0 30 2.07 0.372
1 20 1.90 Table 10: ANOVA VED_DEGREE * DUMMY_DANW
31
From this ANOVA test (table 10), we can conclude that the means of both groups don’t differ
significantly. It can be deduced that companies that produce dangerous waste don’t report in a
less or more exhaustive way than companies not producing dangerous waste.
IND N Mean P-Value
VED_DEGREE 0 36 2.03 0.625
1 14 1.93 Table 11: ANOVA VED_DEGREE * IND
After analysing this test (table 11), we can conclude that the means of both groups don’t differ
significantly. Companies in the different industries don’t report in a more or less elaborate
manner when it comes to voluntary disclosure on waste policy.
DUMMY_FIN_PER N Mean P-Value
VED_DEGREE 0 5 2.60 0.017(a)
1 38 1.87 Table 12: ANOVA VED_DEGREE * DUMMY_FIN_PER
(a) Significant on a 0.05 level of significance
The mean of the group with a positive ROC do differ significantly from the mean of the group
with a negative ROC. Consistent with the test’s results, companies with a negative ROC report
more extensively about waste management than companies with a positive ROC.
At last, a general regression analysis is run without dummy variables. In this regression, all
relevant variables are included in the same model, which can give valuable results.

Dangerous waste, industry and age are important elements to take into account when
identifying the critical factors of the extent of VED. Industry wasn’t an influencing indicator
when analysed on its own. However, in the regression analysis above (table 13), it gained more
importance. This is probably because, in the same model, other variables are taken into
consideration.
It is curious that, unlike when we analysed the presence of VED, in this analysis, size is not a
crucial factor anymore. Age has become a critical influencing component. It shows us that the
younger the company is, the more extensively it discloses on waste information.
7.2. Additional Problem Statement 2
In the previous analyses of this paper, we have concluded that in general, companies don’t
voluntarily disclose about waste policy. Therefore, it is interesting to try to find one
overarching reason why companies don’t engage in VED. It is quite obvious why small waste
producers don’t disclose on waste policy, they simply don’t have the incentive to do so. But
major waste producers should be more transparent towards their stakeholders. Apparently
they aren’t since, in this data base, only 27 % of the major producers have information on their
waste policy on their corporate websites. In this additional analysis, we will try to find out
which motives there are for majors polluters not to voluntarily disclose waste information.
Why do heavy waste producers not report on waste policy on their corporate website?
7.2.1. Descriptive Statistics
In order to solve this problem, only the companies that are major polluters were selected.
Major polluters are companies producing more waste than average. In both industries, 85
major polluters were identified. There are 39 companies in the construction industry
producing more waste than the average of this industry, and 46 major polluters in the food
industry.

7.2.2. Covariance Analysis
A correlation table (appendix V) shows that the dependent variable VED is correlated with
both size and industry. We will probably find the same results when running a regression
analysis. Some other independent variables are mutually correlated but the correlation
coefficients aren’t high enough to raise any complications during further analysis.
7.2.3. Results
A regression analysis is computed to find out which factors drive major polluters to report on
their waste policy13.
13 No significant results were found when computing a regression analysis including dummy variables.
Therefore, this analysis won’t get further attention in this paper.

This additional analysis doesn’t really give us extra information about reasons to disclose. The
regression states that the same factors than those in the analysis on the presence of VED
(section 6.) need to be taken into account when analysing only the major polluters. More
major polluters will disclose if they’re operating in the food industry than when they operate in
the construction company. The size of a company is also an element that needs to be kept in
mind. The smaller the company, the less it will voluntarily disclose on waste.
7.3. Additional Problem Statement 3
As in this study, a clear distinction is made between 2 different industries, an additional
analysis of those industries separately, is recommended.
Do the elements having a crucial role on a general analysis combining both industries, have the
same important influence when analysing both construction and food industry separately?

Figure 12: Number of Companies per Dimension and Industry
Figure 12 gives us a comparison of both industries concerning the companies’ dimensions. 50 %
of the construction companies are small. This is in contrast with only 38% of the food
companies. In comparison with the construction industry, companies from the food industry
are more concentrated in the medium and big sized area (61 %). These observations can have
an influence on the analysis of the separate industries.

Figure 13: Types of waste in the Construction Industry

The construction industry produces 5 times more dangerous waste than the food industry. Just
as with the differences of dimensions of the companies described above, this can have an
effect on the separate analyses of the industries.
7.3.2. Covariance Analysis
From the covariance analysis in appendix VI, we can see that in the construction industry the
presence of VED on corporate websites is correlated with the size of a company. In the food
industry, the presence of VED is correlated with both the size of a company and the volume of
waste it produces. Other correlations present in this table do not imply any problematic

8. Conclusion
From all the results described in the previous paragraphs, some conclusions can be drawn.
First of all, consistent with hypothesis 1, companies in general, don’t report on waste policy on
their corporate websites. Only a small minority of the companies do so and the majority of the
companies that disclose are operating in de food industry (hypothesis 4).
In contrast with the voluntary disclosure theory and the legitimacy theory (paragraph 4.2.),
the environmental performance of a company has no influence whatsoever on the decision to
voluntarily disclose waste information. Hence, these theories that apply on general
environmental reporting, don’t apply on waste reporting (hypothesis 2).
The mere fact of producing dangerous waste has more effect on waste reporting than the total
volume of dangerous waste production in a company. The production of safe waste has an
effect as well. Thus, we can conclude that the type of waste a company produces does have an
important effect on a company’s decision to disclose waste information (hypothesis 3).
However, as there is such a large volume of safe waste present in both industries and that the
amount of dangerous waste can be almost neglectable (figure 3), we can presume that it is the
total of overall waste produced by a company which has such an influencing effect.
When analysing the control variables, only the size of a company seems to have an important
effect on waste disclosure. This might be the result of the larger economies of scale big
companies can achieve and that, therefore, detailed reporting is less costly for them. Bigger
companies might also be aware of their high visibility towards the public and the media and
publicise more information as a reaction (Al-Tuwaijri, Christensen and Hughes II, 2004).
During additional analyses other interesting findings were identified. When studying the
degree of waste reporting, other influencing variables than those found in the main analysis,
were identified. In this additional analysis, unlike in the previous findings, the voluntary
disclosure theory was consistent as it seemed that good performers disclosed in a more
extensive way than bad performers. This can be due to the eagerness of companies to
announce ‘good news’. Furthermore, having a negative or positive ROC appear to have an
influencing effect. Companies having a positive ROC have more elaborate disclosures, probably
because they have more resources which makes reporting less costly for them than their peers
having a negative ROC. Moreover, the presence of dangerous waste in a company doesn’t
have the same importance than in the main analysis. However, the volume of dangerous waste
40
produced by a company has now significant influence. The most curious finding in the first
additional problem statement, is that size has completely lost its influencing effect. Age has
gained in importance now. When reporting, the younger the company, the more extensively it
will do so. This might be because young starters are less conservative and more aware of the
added value elaborate communication has towards stakeholders.
Apparently, not even a third of the major polluters disclose about waste policy. We tried to
find a reason why major polluters don’t disclose despite of the incentive they have to be
transparent and the accountability they have to justify their major waste production.
Nevertheless, size and industry keep being influencing factors and major polluters won’t report
on waste management if they are small companies. Major polluters from the food industry do
disclose a little more than polluters in the construction industry.
In a last additional analysis, we have found that companies from the two industries have
different stimulants to disclose. In the construction industry, size is important. This can be
explained because construction companies are generally smaller than food companies. Food
companies are bigger by nature and won’t be exposed to this effect as much as the
construction companies. In the food industry, the total volume of safe waste is a decisive
factor. As described in section 4.5.4., this is probably because food companies want to
reassure their clients no dangerous substances are used in their food manufacturing and
guarantee that their products are completely safe and cause no health damage.
When taking a closer look at the results of this last analysis, some thoughts came forward. The
influencing factors that come forth in the regressions, are not the same as the critical
components the general regression of the main experiment reveals (tables 7a – 7b). Both
industries have only one decisive factor that influences voluntary disclosure and it is different
for both industries. Size has a crucial role in the construction industry and the volume of safe
waste is fundamental in the food industry. As both elements are also essential factors in the
main analysis, this means that the results of the separate analyses are strong enough to have
an impact when combining both industries in one general analysis. When analysing both
industries combined, extra indicators to voluntarily disclose waste information are revealed.
This means that, across the industries’ borders, we can also find components that have an
overall effect.
A general conclusion is that, just like in the general environmental reporting, a lot of factors
are influencing the decision to voluntarily disclose on waste information.
41
9. Limitations and Future Research
This study presents some limitations that need to be mentioned and taken into consideration
when interpreting the results. Future research could offer some solutions to these limitations.
First, only two industries were analysed in this paper. Therefore, a generalisation toward other
industries can hardly be made as different industries can be quite diverse. In future research,
other sectors could be studied to be able to offer a more general view of the matter.
Second, in this study, the reporting behaviour of Flemish companies were investigated. This
entails that we are studying a very homogenous landscape since a majority of Flemish firms
are SME’s. It is possible that these kind of companies don’t report on waste management
merely due to their specific nature. It may be interesting to execute this study on bigger and
listed companies. As those companies are scarce in Belgium, studies across the country’s
borders are in order.
Another implication of studying only Flemish companies is that we can’t know how companies
from Brussels and Wallonia behave. Since other regulations on mandatory reporting exists in
these parts of the country, the voluntary reporting behaviour of companies in Brussels and
Wallonia could be different from the voluntary reporting behaviour in Flanders.
Third, not all the explanatory variables that proved to be influencing in the literature, were
included in this study. It is useful to perform further research including other predictors such
as media visibility and the presence of external certifications (e.g. ISO 14001).
Fourth, making a comparison analysis between what is reported on a company’s website and
the reality, can be a worthy study. The information that needs to be reported to the
government is of a totally different nature than the information that is found on websites.
Finding out if the information disclosed on a company’s website is consistent with the
information the company communicates to the government, can lead to valuable results.
Especially with companies providing quantitative waste information on their website, the
uncertainty of the reliability of this information remains.
Fifth, other specific topics from environmental reporting should be studied. It would be
interesting to compare companies’ reporting behaviour when it comes to water, energy and
emission reporting as well.
42
Finally, an analysis of voluntary reporting behaviour through the years would offer useful
information. Will companies be more willing to report in detail on all the specific aspects of the
environmental matter in the future?

Appendix I: OVAM (November, 2011). Interview about mandatory reporting in Flanders.
Mechelen, Belgium.
Interview with Bart Vangilbergen
- Is er een centrale controle over het IMJV die de Vlaamse bedrijven moeten indienen?
Verschillende instanties zijn bevoegd voor bepaalde delen van de wetgeving. Het is
niet zo dat OVAM alles gaat controleren. Het IMJV is onderverdeeld in deelformulieren en elke
partner van het IMJV is verantwoordelijk voor zijn deelformulier en kan de nodige stappen
ondernemen om de relevante informatie te verkrijgen.
Binnen het IMJV is er een stuurgroep waarbij een overleg is met de verschillende
instanties. Daar kan de OVAM aangeven welke informatie zij wilt bekomen en op welke manier
die moet opgevraagd worden. In het IMJV komen dan de deelformulieren, er is een
deelformulier voor LNE, voor VMM is er een deelformulier en dus ook voor OVAM. Deze
formulieren worden opgestuurd naar de bedrijven toe als 1 geheel zodat de bedrijven het
gevoel hebben dat ze maar één bevraging moeten invullen. Zij moeten dit ofwel digitaal ofwel
op papier naar een centraal punt terug sturen in Brussel en van daaruit wordt elk
deelformulier opgestuurd naar de bevoegde instantie. Zijn er bedrijven die de rapportering
niet (volledig) doen, dan krijgen zij een aanmaning om dit alsnog te doen.
- Hoe wordt er bepaald welke bedrijven moeten rapporteren?
Dat zijn de partners die dat bepalen. Voor OVAM zijn er een aantal criteria waarop wij
ons baseren om een aantal bedrijven aan te schrijven. Voor afval gebruiken wij bijvoorbeeld
een steekproef. Vroeger moesten alle bedrijven daarover rapporteren, nu gebruiken wij een
steekproef. Naast de steekproef zijn er nog een aantal bedrijven die verplicht zijn om aan de
rapportering te voldoen. Voor een deel bepalen we het dus zelf, voor een deel wordt het
wetmatig bepaald. Dit jaar is onze steekproef ook erg ingekort omdat wij minder naar Europa
toe moeten rapporteren. Een uitgebreide rapportering naar Europa moet maar om de 2 jaar
gebeuren. Jaren dat er niet uitgebreid gerapporteerd moet worden, zorgt er dan ook voor dat
dat voor ons minder werk is en ook een minder grote werklast is voor de bedrijven. We
proberen de bedrijven zo weinig mogelijk te belasten omdat het voor hen niet altijd evident is
X
om al deze informatie te verzamelen. Het zijn dan ook niet altijd dezelfde bedrijven die in de
steekproef zitten en die dus aangesproken worden.
Het is ook zo dat niet elk bedrijf alle deelformulieren moeten invullen. In functie van
wat hun activiteiten zijn, wordt er besloten welk deelformulier zij moeten invullen. Sommige
bedrijven zullen dus maar 1 of 2 deelformulieren moeten invullen, anderen alle 5.
In onze topjaren zijn er om en bij de 15000 bedrijven die bij OVAM moeten
rapporteren.
- Wat doen jullie met de gegevens die jullie krijgen?
De gegevens worden gebruikt om het afvalbeleid op af te stemmen, waar situeert het
afval zich, in welke sector… Elke sector wordt namelijk aangeschreven, wij weten perfect dat
een bakker met dat aantal werknemers zoveel van welk soort afval produceert. Wij gaan dus
ons beleid hierop afstemmen. De cijfers worden ook gebruikt voor rapportering naar Europa
toe.
- Worden de gegevens naar de pers toe gecommuniceerd?
Er wordt niet als zijnde IMJV naar de pers gegaan. Maar er worden wel algemene
rapporten gemaakt van onze resultaten en die zijn vrij beschikbaar op de website.
- In VLAREM I wordt er bepaald welke bedrijven onder de rapporteringplicht vallen…
In de VLAREA staat dat als wij informatie willen krijgen wij het recht hebben om deze
op te vragen. Op basis van dat artikel vragen wij bijvoorbeeld aan stortplaatsen en
verbrandingsovens bepaalde gegevens op.
- Is er enige mogelijkheid dat ik deze gegevens zou mogen gebruiken in mijn masterproef?
De gegevens worden in een algemeen rapport gegoten en deze mogen opgevraagd
worden. Veel van die rapporten staan ook op de website. De publicaties kunnen dan vrij
geraadpleegd worden over de jaren heen. De specifieke gegeven zou je normaal gezien mogen
gebruiken als dit inderdaad in het kader van jouw masterproef gebruikt wordt en dat de
bedrijven niet bij naam genoemd worden.
- Waarom zou OVAM beslissen om extra informatie bij een bedrijf op te vragen (informatie die
normaal niet opgevraagd wordt maar o.b.v. het VLAREA decreet kan bekomen worden)
XI
Er kan bijvoorbeeld een project zijn over een bepaalde stroom, biomassa, kunststoffen.
We zouden ons dus kunnen focussen op die stroom en deze van naderbij willen bekijken. Dan
wordt daar een enquête over gemaakt en opgestuurd naar bedrijven waarvan wij weten dat zij
daarmee bezig zijn.
- Worden de gegevens van bepaalde bedrijven over de jaren heen vergeleken?
We vergelijken de gegevens van de sectoren over de jaren heen, niet van individuele
bedrijven. Het zou wel kunnen dat bepaalde diensten en teams dit wel doen. Ik kan aannemen
dat bepaalde stortplaatsen en verbrandingsovens individueel worden opgevolgd. Maar voor
bedrijfsafvalstoffen zal er niet individueel naar gekeken worden.
- Als nu een bepaald bedrijf het 1 jaar zeer slecht doet, dat ze overdreven veel afval heeft
geproduceerd, zal ze dan het volgende jaar extra in de gaten gehouden worden?
Ook daarvoor worden enkel de sectoren of afvalstromen opgevolgd. We zouden dus
wel kunnen zien dat een bepaalde sector het in het algemeen slecht doet en dan gaan we ons
beleid daarop toespitsen.
- Worden er sancties opgelegd aan bedrijven die te veel afval zouden produceren?
Neen, het is voor de bedrijven zelf niet interessant om veel afval te produceren, dat is
zeer duur voor een bedrijf. Je moet dat afval dan afvoeren maar ook de verwerking moet je
dan betalen. Er is een beetje zelfregulering, je zorgt er gewoon voor jezelf voor dat er zo
weinig mogelijk afval is.

A Milieu heeft bij Aannemingen Janssen nv een dubbele betekenis: enerzijds zijn we actief in de milieusector, meer bepaald in de waterzuivering; anderzijds zijn we ten zeerste begaan met de veiligheid en het respect voor de medemens. Getuige hiervan is ons VCA** veiligheidscertificaat sinds december 1996, het gebruik van bouwmaterialen die zo weinig mogelijk milieubelastend zijn en een selectief beheer van afval.

H ‘Bedrijf H’ realiseerde zich als één van de eersten dat men niet ongestraft het milieu kan blijven belasten met bouw- en sloopafval. Het bedrijf draagt milieupreventie, recyclage en kringloopgebruik hoog in het vaandel. Daarom werd in 1985 al het Brussels Recycling Center (BRC) geopend, een onafhankelijke breekwerf die voldoet aan de strengste eisen.
Het Brussels Recycling Center is één van de 9 breekcentrales in België die COPRO-gecertificeerd is. Jaarlijks wordt 130.000 ton aan slooppuin aangevoerd en verwerkt. BRC staat ter beschikking van andere wegenbouwondernemingen en gebouwenslopers die kunnen rekenen op een feilloos verwerkingsproces van
2
XIII
hun bouwafval en sloopafval. Volgende activiteiten vinden plaats in het BRC:
- Sorteren van slooppuin: betonpuin, asfaltpuin en metselwerkpuin
- Verpulveren van grote stukken met betonverpulveraar
- Breken in percutiebeker
- Afzeven van gebroken materiaal in zeefinstallatie
I Als milieubewust bedrijf streven we naar een maximale scheiding van materialen. Zowel het gevaarlijk als het niet-gevaarlijk afval voeren we af in overeenstemming met de milieuwetgeving.
Een maximale recyclage van afbraakmateriaal staat centraal in het milieubeleid van het bedrijf. Sinds 2005 heeft ‘Bedrijg I’ daarom zijn eigen recyclagecentrum, ABR.
2
J Volgens het principe van de LCA is hout een uitermate milieuvriendelijk materiaal.
De Life Cycle Analysis (LCA) meet de impact van een materiaal op de omgeving en de natuur, en dat tijdens de verscheidene stadia van zijn levensloop. Hout scoort in alle stadia zeer hoog: zowel voor de productie, de ontginning, de vernietiging, de verwerking, het gebruik en het recycleren.
Hout is duurzaam, hernieuwbaar en recycleerbaar. Houtverwerking levert amper afval op, en zelfs de kleinste houtspaanders worden opnieuw gebruikt, gerecycleerd of benut als groene brandstof. Van alle bouwmaterialen vereist hout ook het minst energie voor transport en voor de verwerking tot afgewerkte producten. Aangezien hout stevig is en over een lange levensduur beschikt, is het bovendien minder snel aan vervanging toe.
Voor onze woningen gebruiken we uitsluitend Canadese oregon dat afkomstig is uit bossen die speciaal voor dit doel zijn aangeplant. Dankzij het gecontroleerd bosbeheer wordt geen roofbouw gepleegd, en de quota voor verplichte nieuwe aanplantingen zijn strikt vastgelegd.

L ‘Bedrijf L’ hecht veel waarde aan een verantwoorde omgang met materialen, we besteden daarom in onze bedrijfsvoering veel aandacht aan het benutten van materialen voor hergebruik. Daarnaast scheiden wij ons afval zorgvuldig. Het vermindert niet alleen de milieubelasting maar levert ons bovendien een besparing op transport- en stortkosten. Met de juiste partners in de keten kijken we ook naar mogelijke hergebruik toepassingen elders. Een afvalbeheersplan geeft daarbij de mogelijkheid om het scheiden van de verschillende afvalstromen goed te organiseren. Hiervoor werken wij samen met enkele afvalverwerkers waarmee wij afspraken hebben gemaakt over het stroomlijnen van ons afvalmanagement.

N Afval is ook bij de spoorwegen niet te vermijden. In alle takken van het bedrijf probeert men het afval zo efficiënt mogelijk te beheren.
- Werkplaatsen -
In 2010 is ‘Bedrijf N’ gestart met de opwaardering van het industriële afval van de werkplaatsen en logistieke centra infrastructuur (LCI’s). In een eerste stap start ‘Bedrijf N’ met metingen om een beter zicht te krijgen op de afvalstromen. Daarna zullen containerparken worden geïnstalleerd om het afval te sorteren en te verwerken. ‘Bedrijf N’ kan dan gegroepeerde veilingen organiseren voor bijvoorbeeld schroot, koper, aluminium, gebruikte olie of loodbatterijen.
- Bouwwerven -
Op bouwwerven wil ‘Bedrijf N’ de medewerkers en aannemers in de eerste plaats sensibiliseren om het afval te beperken. In de mate van het mogelijke zal het afval van bouwterreinen worden gecentraliseerd om te worden overgenomen, verwerkt en eventueel verkocht.
- Kantoorafval -
In samenwerking met de NMBS-Holding zal ‘Bedrijf N’ het ‘ecopunten’-concept veralgemenen. Daarbij wordt huishoudelijk afval op elke kantoorverdieping verzameld en gesorteerd. Dat kan onder meer ook gebeuren voor PMD, inktpatronen, papier, TL-buizen en klein elektronisch materiaal.

P - De 'papierwinkel' onder de loep -
Het verduurzamen van ons dagelijkse leven begint vaak met het stilstaan bij de kleine dingen die bij nader inzien een grote impact hebben. Zoals deze info.
Eén pallet met printpapier van 9 kg bevat 40 dozen en weegt een ton. Uit een boom
3
XV
worden 16,6 pakken printpapier geproduceerd of 8.333 vellen papier. Door dubbelzijdig printen en gescheiden papierinzameling kunnen we tot wel 50% besparen op printpapier. Daarmee besparen wij bomen en maken we onze CO2-voetafdruk kleiner. Ook is het vaak prima mogelijk om 2 pagina’s op één A4 te printen. Steeds meer printers worden dan ook standaard dubbelzijdig ingesteld.
- Maak er geen puinhoop van -
Goed scheiden van restafval levert de grondstoffen voor nieuwe producten. Hout, puin en metalen worden al voor een zeer groot deel gescheiden voor hergebruik. Het goed scheiden van bedrijfsafval is goedkoper en het is goed voor het milieu, het aanleveren van bijvoorbeeld een ton puin is goedkoper dan een ton restafval.
- Cijfers ‘Bedrijf P’ 2009 -
Printen & kopiëren: 25 ton papier
Drukwerk: 30 ton papier
Hiervoor zijn nodig: 1.300 bomen
Bosoppervlakte: 1.400 m2
Dit zijn 5 miljoen A4-tjes, oftewel 30 A4-tjes per netwerkgebruiker per werkdag

S - ‘Bedrijf S’ is dé specialist op het gebied van recyclage van bouwpuin.
- Aannemers en openbare besturen brengen er puin binnen, t.t.z. opbraak beton, asfalt en mengpuin eventueel vermengd met zand. Deze inerte materialen worden gebroken en gezeefd tot puingranulaten, dewelke als secundaire grondstoffen in de betoncentrale kunnen worden verwerkt. Aldus is ‘Bedrijf S’ een voornaam producent van schraal beton, zandcement en gestabiliseerde steenslag, producten die hoofdzakelijk toegepast worden als gebonden funderingsmaterialen in de wegenbouw.
- De gebroken granulaten hoeven niet steeds gestabiliseerd te worden; zo verkoopt ‘Bedrijf S’ ook gebroken betonpuin, gebroken asfaltpuin en gebroken mengpuin, evenals zeefzand. Deze materialen zijn beschikbaar in verschillende kalibers, al naargelang de behoeften van de klant.
2
T - Milieubewuste afvalverwerking voor de klant -
Onze recyclageafdeling diende één jaar geleden, voor zijn vestiging te Brugge, de aanvraag in voor de ‘Charter duurzaam ondernemen’. Ondermeer door dit charter realiseerden wij verschillende acties rond duurzaam ondernemen. Acties rond tien verschillende thema’s, zoals de opvolging van de sociale en milieuwetgeving –
2
XVI
communiceren en dialogeren – mensvriendelijk ondernemen – duurzaamheid integreren – afval beperken – rationeel waterverbruik – noodprocedures – minimalisatie van de omgevingshinder en reductie van de verkeersimpact werden verwezenlijkt en/of opgestart. Voorbeelden van die ‘groene aanpak’ zijn er teveel om op te noemen. Wat we hier doen is namelijk op zich al groen. Desondanks som ik er toch enkele op:
- alle afvalwater wordt gezuiverd en opnieuw aangewend in het productieproces;
- omgevingshinder door stof, lawaai en trillingen werd tot een aanvaardbaar niveau gebracht;
- het beheer van de groenzone gebeurt op een milieuvriendelijke manier, zonder gebruik te maken van pesticiden;
- alle kuisproducten dragen het eco-label;
- investeringen teneinde het energieverbruik terug te schroeven, zoals het plaatsen van condensatorbatterij en frequentiesturingen, en het opsporen van persluchtlekken, … .”
U Het milieumanagementsysteem is van toepassing op de activiteiten van de hoofdzetel, inclusief de organisatie van het afval en van het transport van en naar de werven, en de verwezenlijking van de sinds 2012 opgestarte projecten in België (Vlaanderen) van : utiliteitsbouw, residentiële bouw, renovatiewerken, bouwkundige onderhoudswerken.
Onze belangrijke milieuaspecten zijn :
- Mobiliteit en transport
- Afval
- Energieverbruik
- Noodsituaties
De doel- en taakstellingen van het milieumanagementsysteem richten zich daarom op de volgende onderwerpen :
Het huidige beleid wat bedrijfswagens betreft verder uitwerken (arbeiders en bedienden)
Optimaliseren van afvalscheiding (kantoor en werven)
Monitoren van het verbruik : elektriciteit, gas, water, brandstof en papier (kantoor)
Het huidige aankoopbeleid uitbreiden zodat ook onze onderaannemers en leveranciers zich engageren om meer milieubewust te ondernemen (kantoor en werven)
- Uitwerken van een duidelijk evacuatieplan
- Verkrijgen van het ISO 14001:2004-certificaat
Daarnaast is de beheersing van significante milieuaspecten opgenomen in het milieumanagementsysteem.

D ‘Bedrijf D’ ziet verpakkingen niet als afval, maar als een waardevolle bron voor hergebruik: een grondstof. Verpakkingen spelen trouwens een belangrijke rol in onze activiteiten. Ze laten ons toe onze producten te transporteren, te verkopen en – qua materiaal en grootte – te voldoen aan de wensen van elke individuele consument. Dankzij onze verpakkingen kunnen we ook communiceren met onze consument. Bovendien garanderen onze verpakkingen de kwaliteit van onze producten.
‘Bedrijf D’ engageert zich om de impact van haar verpakkingen op het milieu te beperken en het gebruik van hernieuwbare, herbruikbare en recycleerbare grondstoffen te maximaliseren.
Wereldwijd willen we het equivalent van 100 % van onze verpakkingen terug inzamelen voor recyclage. Om die doelstellingen te realiseren, werken we op vier pijlers:
Alsmaar lichtere verpakkingen
Stimuleren om te recycleren
Hergebruiken als grondstof
Het gebruik van hernieuwbare grondstoffen.

‘Bedrijf F’ blijft verder zoeken naar mogelijkheden om de hoeveelheid verpakkingsmateriaal per eenheid product te beperken en is voortdurend op zoek naar materialen, die beantwoorden aan alle veiligheids-,betrouwbaarheids- en consumentenvereisten en tegelijkertijd het milieu minder belasten. Ook wordt actief deelgenomen aan de beheerssystemen van verpakkingsafval, zoals Duales-System in Duitsland, Fost Plus in België, Eco-Emballages in Frankrijk en Eco-verpakking iNederland.
- Milieu en exploitative -
Overal binnen de onderneming wordt gestreefd naar verregaande bewustmaking. De milieueffecten worden systematisch onderzocht en op basis van de uitkomsten worden passende maatregelen genomen: preventief (bijvoorbeeld afvalwater), recuperatie (onder meer van papier en karton), verantwoorde vernietiging (zoals bijvoorbeeld de verbranding van verpakkingsfilmafval in gespecialiseerde centra) en rationeel gebruik van water en energie.
G - Waste -
Waste data is split into non-hazardous waste and hazardous waste. Non-hazardous waste is material such as cardboard, paper, plastics, and general trash. Hazardous waste is any material that is dangerous or potentially harmful to human health or to the environment such as liquids, solids, contained gases, or sludge. The non-hazardous waste volume decreased by 40 kTons in 2009,mainly as a result of the changed destination of gypsum produced in the lactic acid process. More of this gypsum volume had an interesting sustainable use in agriculture, as fertilizer for land application. The hazardous waste volume decreased by 22% from 422 Tons to 332 Tons. This is mainly caused by a shift in production volumes in several Purac plants, for example the move of lactic acid production from the Netherlands to Thailand.

I Zorg dragen voor het milieu is voor ons van het grootste belang. Wij trachten de ecologische voetafdruk van onze producten zo klein mogelijk te houden door grondstoffen en verpakkingen zo dicht mogelijk bij ons bedrijf in te kopen. Door het opmaken van een afvalbeleidsplan zijn onze afvalstromen met 90% gereduceerd door recyclage.

J ENVIRONMENT - Planet
We operate with care for the environment and ensure compliance with all applicable laws and regulations.
We select our material and industrial processes in such a way that they contribute to the preservation of the environment and protection of the planet by:
- Reducing energy and water consumption (solar panels, collection of rainwater,
2
XIX
proper insulation,
…)
- Reducing carbon footprint (calculation and improvement plan)
- Improving our waste management:
recycling of carton and plastic.
Fruit waste is collected and turned into bio mass and ultimately alternative energy.
Handling and disposure of chemicals and other dangerous materials emissions and effluent treatment are in place.
K - Life cycle assessments -
Life Cycle Assessments (LCAs) reveal the environmental performance of products during and beyond their life cycle. They can also be used to compare the eco-performances of different products in the same application. As such, they are an important tool in validating the ECO+ scores of our products. They also help us identify ways to minimize our products’ eco-footprints.
The awareness of a product’s total eco-effect stimulates us to develop new products with a lower eco-impact. It also helps us improve performance. For instance, we can use less fossil fuel during production, or reduce losses in the production process, and we can recycle products when they reach the waste stage. At the same time, we can increase a product’s usability lifetime and reduce its energy consumption.
- Creating transparency -
Our goal is to carry out LCAs for all of our products, from the extraction of raw materials until the moment the product leaves the factory gate. At year-end 2010 we determined the ‘cradle to gate’ footprint (that is, from the extraction of raw materials until the moment the product leaves the DSM factory gate). In addition, for all new products we carry out full LCAs, including the use and waste stages, in other words ‘from cradle to grave’.. We provide our customers with access to the outcomes of these assessments so that they can carry out LCAs for their own products. In this way, we contribute to the eco-transparency of the overall value chain.

T ‘Bedrijf T’ heeft een enorm brede waaier aan moderne en milieuvriendelijke verpakkingslijnen. Zo bracht ze als eerste in Europa langhoudbare consumptiemelk in grootverpakkingen van 10L tot 1000L. Voor de Nederlandse markt is er de specifieke 2L can verse melk. ‘Bedrijf T’ is stichtend lid van Fost +. Fost Plus promoot, coördineert en financiert de selectieve inzameling, de sortering en de recyclage van huishoudelijk verpakkingsafval in België. Ook in Frankrijk zijn we lid van Eco-emballage en in Nederland van Stichting Retourverpakking. In 2011 zullen al de door ons op de markt gebrachte tetra Brik en Gable Topverpakkingen vervaardigd worden met FSC gekeurd karton “Het FSC –label garandeert de duurzame oorsprong van het papier omdat niet enkel het bos van oorsprong wordt gecontroleerd maar ook de hele handelsketen tot bij de eindconsument. De eindklant krijgt aldus de absolute garantie dat dit papier afkomstig is van goed beheerde FSC gecertificeerde bossen”

100% recycleerbaar. Een tweede leven zonder verlies.
Niet onbelangrijk is het gebruik van Tetra Pak kartonnen verpakkingen. Niet echt duurzaam zal u zeggen. Toch wel. Deze samengestelde kartonnen verpakkingen worden gemaakt van klein hout en houtafval van zagerijen. Bovendien wordt enkel hout van duurzaam beheerde Scandinavische bossen gebruikt. Gekapte bomen worden voortdurend vervangen door nieuwe. Hierdoor blijven de bossen jong en gezond en neemt de bosomvang toe. Belangrijk, want bossen zijn de motor voor het behoud van ons klimaat.
Alle door ‘Bedrijf U’ gebruikte Tetra Pak verpakkingen zijn voorzien van een FSC-certificatie (Forest Stewardship Council). Dit certificaat geeft zekerheid over verantwoord bosbeheer. Dit betekent een zorgvuldig aanplant-, onderhouds- en kapbeleid, met respect voor ecologische en sociale aspecten, zoals biodiversiteit en arbeidsomstandigheden. Het FSC-keurmerk garandeert de volledige traceerbaarheid van het hout, van bos tot eindproduct. U kan dus opgelucht blijven ademhalen. Tetra Pak verpakkingen zijn niet enkel gemaakt van duurzame grondstoffen. Ze zijn ook 100% recycleerbaar. De kartonvezels krijgen een tweede leven als kartonnen doos, briefpapier of keukenrol. Wist je dat in België al meer dan 75% van de drankkartons wordt gerecycleerd?
V We care deeply about the earth and future generations. So we act responsibly by finding creative and inspired ways to reduce waste, recycle and re-use existing resources.
Demands on the planet are increasing. And in some areas, our natural resources are being depleted faster than they can be replenished. As one of the largest food companies in Europe, we understand the important role we play in respecting our natural resources and using them thoughtfully.
So we’ve cooked up a recipe for reducing our impact on the environment. There are many ways we can make a difference – from using less water in our manufacturing, to reducing product packaging, to producing less waste.
In 2006, we set aggressive five-year global goals*. We expanded them in 2010, after integrating the Cadbury and LU businesses, looking to build and improve upon our successes. For our 2011–2015 goals, we’ve added sustainable agricultural commodities and transportation to what we’re measuring.

BB As for waste, we have identified three areas in which to focus attention on waste management. These are solid waste, mortalities and organic waste. Recycling is a good option for solid waste, especially for feed bags. These are recycled in almost all Marine Harvest farming operations. Programmes to reduce waste and increase recycling are in place in all Marine Harvest businesses.

DD Het respect voor het leefmilieu en de ontwikkeling van duurzame landbouwpraktijken zijn onontbeerlijk om het voortbestaan van onze landbouw- en voedingssector te verzekeren. We proberen aanhoudend onze criteria voor de productie “van het veld tot op je bord” nog te verbeteren aan de hand van: - het gebruik van duurzame en doeltreffende energiebronnen
- de beperking van het waterverbruik
- het gebruik van recycleerbare verpakkingen
- een uiterst strikt afvalbeheer
- een continu verbeteringsprogramma met betrekking tot onze milieuacties (ISO 14001 certificering)

JJ De Ladder van Lansink is een standaard op het gebied van afvalbeheer. De Ladder werd genoemd naar de Nederlandse politicus Ad Lansink. Hij kwam in 1979 op het idee om in het afvalbeleid de prioriteit te geven aan de meest milieuvriendelijke verwerkingswijzen.
Bovenaan de 'ladder' staat preventie, hergebruiken en recycleren. Zijn doel was zo veel mogelijk afval de Ladder van Lansink te laten 'beklimmen'.

PP We willen dat onze producten mooi en gebruiksvriendelijk worden verpakt, met zorg voor de smaak en de kwaliteit van de inhoud. Onze ingenieurs en leveranciers ontwerpen verpakkingen die het milieu zo min mogelijk belasten. Ze kijken voortdurend naar optimalisatie van de verpakkingen en de processen.
Het afval dat tot stand komt in een productieproces hergebruiken we zo veel mogelijk. We praten hier bijvoorbeeld over het zetmeel dat vrijkomt in het productieproces van de chips dat we verkopen aan de papierindustrie. Er is maar een klein gedeelte dat we niet kunnen recycleren, en moeten verbranden, maar daar zorgen we dat we de energie die bij de verbranding vrijkomt, terugwinnen.
Ook aan de hoeveelheid verpakkingsmateriaal wordt gewerkt. Chipszakjes bevatten een minimum aan aluminium om het product vers te houden, hier kijken we of we de bestaande zakjes niet kunnen vervangen door biologisch afbreekbare verpakkingen die het product nét zo vers houden. Een ander voorbeeld is PET, dat de consument omwille van zijn gebruiksvriendelijkheid verkiest boven glas of karton. We willen deze consumentenvoorkeur respecteren, en analyseren daarom de mogelijkheden om minder materiaal te gebruiken in de productie van PET flessen, en doen onderzoek naar betere recyclagemethoden.
Onze beloftes en initiatieven
- Geen afval storten. -
Recyclage van het overgrote deel van ons afval. Een minimaal deel wordt verbrand, maar met terugwinning van de vrijgekomen energie.
Samenwerking met Fost+ en Val-I-Pac voor de recyclage van blikjes en verpakkingen.
Partner in het Refrigerants Naturally project, waar we met andere voedingsmiddelengroepen samen streven om milieu-onvriendelijke koelvloeistoffen te vervangen door natuurlijke alternatieven.
Onze Elopak-verpakkingen van ‘Bedrijf PP’ dragen het FSC-label, een certificaat dat

QQ Milieu vormt een essentieel onderdeel van het totale ondernemingsbeleid van ‘Bedrijf QQ’. De zorg voor het milieu is geïntegreerd in de dagelijkse werkzaamheden en wordt op dezelfde wijze gewaardeerd als alle andere primaire ondernemingsdoelstellingen. Om dit aan te tonen heeft ‘Bedrijf QQ’ het milieucharter ondertekend.
Het milieubeleid van ‘Bedrijf QQ’ is gericht op het continu verbeteren van de milieuaspecten binnen de organisatie.
‘Bedrijf QQ’ zal zich met name op de volgende terreinen gaan richten :
Het verminderen van het energieverbruik door een verhoogde efficiëntie
Preventie van afval en optimalisatie van de afvalscheiding
Duurzaam inkopen
Versterken van het milieubewustzijn van haar eigen medewerkers
Deze doelen worden verder uitgewerkt in het actieplan dat in de milieuverklaring van het milieucharter terug te vinden is.
