PREAMBLE

Environmental auditing, now renamed as Environmental Statement, is a tool comprising a

systematic, documented, periodic and objective evaluation of how well a unit is performing in order

to achieve the objective of the waste prevention and reduction, assessing compliance with regulatory

requirements and placing environmental information in public.

The preparation and submission of environmental audit report was mandatory under the

Environment (Protection) Rules, 1986 (second amendment) since March 1992. The industrial units

requiring consent under section 25 of the Water Act were required to submit environmental audit

report for the financial year to the Board on or before the 30th

of September every year beginning

from the year 1993.

Environmental Audit is a technique being introduced for integrating the interest of the industry and

the environment so that these could be mutually supportive. This technique is basically a part of

industry’s internal procedures in meeting their responsibilities towards better environment. A

notification under The Environmental (Protection) Rules, 1996 has been issued on April 22, 1993,

requiring industries to submit an environmental statement for the financial year ending on March 31

in Form V to the concerned State Pollution Control Boards on or before September 30 every year

beginning 1993 (Annexure I). The Department of Company Affairs also agreed to include this

requirement as a part of the Director’s Annual Report. The submission on an environmental

statement is applicable to the following.

1. Those who require consent under the Water (Prevention & Control of Pollution) Act, 1974

2. Those who require consent under the Air (Prevention & Control of Pollution) Act, 1981, and

3. Those who require authorization under Hazardous wastes (Management & Handling) Rules,

1989.



BENEFITS OF ENVIRONMENTAL AUDIT:

Benefits of Environmental Audit Environmental auditing have far reaching benefits to the industry,

to the society and the nation at large. It

i) Determines how well the process systems and pollution control systems are performing, and

identifies the operations of poor performance

ii) Identifies potential cost savings which can be accrued through reduction in raw material

consumption by way of waste minimisation, and adoption of recycle/recovery/reduction in

pollution load

iii) Increases awareness of environmental requirements, policies and responsibilities

iv) Helps in understanding the technical capabilities and attitude of the environmental

organisation in a Company

v) Provides up-to-date environmental database for use in plant modification, emergencies etc.

vi) Unravels surprises and hidden liabilities due to which regulatory risk and exposure to

litigation can be reduced

vii) Ensures independent verification, identifies matters needing attention, and provides timely

warning to management on potential future problems and helps to safeguard environment,

and assists in complying with local, regional and national laws and regulations, with the

Company's policy and with the environmental standards.



OBJECTIVES OF ENVIRONMENTAL AUDIT:

OBJECTIVES OF THE ENVIRONMENTAL AUDIT HELPS IN POLLUTION CONTROL, improved production,

safety and health and conservation of natural resources and hence its overall objective can be stated

as achieving of sustainable development. However for conducting environmental audit, objectives

are to be defined clearly, or else the audit procedure will be subject to varying interpretations which

may yield and contribute to differences in approach thereby influencing the end results. The

objectives of environmental audit in an industry are:

i) To determine the mass balance of various materials used and the performance of various

process equipment so as to identify usage of materials in excess than required, to review the

conversion efficiencies of process equipment and accordingly fix up norms for

equipment/performance and minimisation of the wastes.

ii) (a) To identify the areas of water usage and wastewater generation and determine the

characteristics of wastewater; (b) to determine the emissions, their sources, quantities and

characteristics; and (c) to determine the solid wastes and hazardous wastes generated, their

sources, quantities and characteristics.

iii) To identify the possibilities of waste minimisation, and recovery and recycling of wastes

iv) To determine the performance of the existing waste treatment/control systems so as to

modify or install additional or alternative control equipment accordingly

v) To determine the impact on the surrounding environment (groundwater, stream, residential

area, agricultural area, sensitive zone, etc.) due to the disposal of wastewater, emissions and

solid wastes from the industry and accordingly identify suitable preventive measures. If

necessary

vi) To verify compliance with the standards and conditions prescribed by the regulatory bodies

under the Water Act, the Air Act and the Environmental Protection) Act; and



vii) To check the effectiveness of (a) organisational set-up of the industry for decision-making

and environmental management with special reference to their 'technical' view point,

'attitudinal' view point and training, and (b) environmental policy of the Company

viii) Environmental audit helps in assessing the use of raw materials (whether in excess or not)

and various methods to be adopted to recover the same . it also helps in periodical

assessment of the treatment schemes adopted for abatement of various pollutants generated

like wastewater, air and solid waste etc. and to modify the same to achieve better working

efficiency.

ix) Environmental auditing has far reaching benefits to the industry. to the society and the nation

at large. it helps in determining the working efficiencies of process and pollution control

systems. It helps in determining the working effaces of the process and pollution control

systems .it also aids in identifying the cost saving techniques that can be adopted and it

provides an up to date environmental data for use in emergencies. It helps in understanding

the technical capabilities and attitude of an organisation towards pollution control and

increases the awareness of environmental requirements. It ensures independent verification,

identifiesmatters needing urgent attention, provides warnings on potential futures problems

and thus reduces exposure to litigation. It mainly helps in safeguarding the environment and

assists in complying with regulatory norms of local, regional and national laws.

Environmental audit thus in pollution control and in improving production, safety, health ,and

conservation of natural resources.

I. MANUFACTURING PROCESS OF SODIUM HYDRIDE:

A. Raw materials: Sodium metal, Hydrogen Gas in Cylinders, Mineral oil.

B. Manufacturing Process:

Sodium is heated to a temperature of around 180 C to 250 C in a SS reactor containing mineral

oil under nitrogen atmosphere. The heating of the reactor is done with thermic fluid. Once the

required temperature is attained Hydrogen Gas is passed into to the reactor from the cylinder.

When the reaction is completed, the sodium hydride dispersion in oil is cooled and unloaded into

a receiver and then it is packed in polythene bags under nitrogen atmosphere and kept in MS

drums/HDPE drums.

II. MANUFACTURING PROCESS OF SODIUM AMIDE:

A. Raw materials: Sodium metal, liquid ammonia cylinder

B. Manufacturing Process:

Sodium is charged into a MS reactor and the temperature is maintained to 300 C to 350C then

Ammonia gas is passed into the reactor and when the reaction is completed, the mass is

unloaded in to a ball mill and powdered. The powder is packing in polythene bags either 5kgs as

per the requirement of the customers and kept in MS drums. The excess ammonia and hydrogen

are flares in atmosphere.

III. MANUFACTURING PROCESS OF N-ethyl piperazine ;

Piperazine is reacted with diethyl sulfate and sodium hydroxide flakes in presence of toluene

solvent in reactor at a temperature of 80oC for 13 Hours duration. After mono alkylation’s of

piperazine, the reacted material is sent for layer separation by gravity. The aqueous layer

saturated with sodium sulphate is separated here. This sodium sulphate is recovered as by

product and sold to customers. The mass is then transferred to vacuum filter in which toluene is

separated and recycled back to reactor. The organic layer is sent to distillation column where

benzene is separated at low boiling point of 80oC for 4 hours duration by circulating steam .

Further the remaining liquid is fractionally distilled at 150oC by circulating furnace oil to

maintain that temperature for 4 hours time to get the final pure product N-ethyl piperazine in

liquid form.
