The document discusses industrial solid waste management. It notes that industrialization has caused environmental pollution as a byproduct of growth. Efforts must be made to control pollution from waste disposal by converting wastes into usable raw materials. There are challenges in managing industrial solid waste from small industries. Proper collection and disposal requires cooperation between local bodies, pollution control boards, and industries. The document outlines various sources and types of industrial solid waste and methods for their disposal and recycling.

1. Industrial Solid Waste
Management

2. Introduction
Environmental pollution is the major problem associated
with rapid industrialization, urbanization and rise in
living standards of people.
For developing countries, industrialization was must and
still this activity very much demands to build self reliant
and in uplifting nation’s economy.
However, industrialization on the other hand has also
caused serious problems relating to environmental
pollution. Therefore, wastes seem to be a by-product of
growth..

3. On the other hand, with increasing demand for raw
materials for industrial production, the non-renewable
resources are dwindling day-by-day.
Therefore, efforts are to be made for controlling pollution
arising out of the disposal of wastes by conversion of
these unwanted wastes into utilizable raw materials for
various beneficial uses.
 The problems relating to disposal of industrial solid
waste are associated with lack of infrastructural facilities
and negligence of industries to take proper safeguards.
 The large and medium industries located in identified
(conforming) industrial areas still have some arrangements
to dispose solid waste.

4. However, the problem persist with small scale industries.
 In number of cities and towns, small scale industries
find it easy to dispose waste here and there and it makes
difficult for local bodies to collect such waste though it is
not their responsibility.
 In some cities, industrial, residential and commercial
are mixed and thus all waste gets intermingled.
Therefore, it becomes necessary that the local bodies
along with State Pollution Control Board (SPCB) work
out requisite strategy for organizing proper collection
and disposal of industrial solid waste.
 Management of Industrial Solid Waste (ISW) is not the
responsibility of local bodies.

5. Industries generating solid waste have to manage such
waste by themselves and are required to seek
authorizations from respective State Pollution Control
Boards (SPCBs) under relevant rules.
 However, through joint efforts of SPCBs, local bodies
and the industries, a mechanism could be evolved for
better management.
Industries are required to collect and dispose of their
waste at specific disposal sites and such collection,
treatment and disposal is required to be monitored by
the concerned State Pollution Control Board (SPCB)

9. Disposal of Industrial waste
Following are the methods of disposal of
industrial waste.
1. Land filling
2. Incineration
3. Composting
4. Recycling

10. 1. Inventory Management and Improved Operations
· Inventorisation and tracing of all raw materials ;
· Purchasing of fewer toxic and more non-toxic production
materials.
· Implementation of employees’ training and management
feedback
· Improving material receiving, storage, and handling
practices
Waste management Technique

11. 2.Modification of Equipment
· Installation of equipment that produce minimal or no wastes .
· Modification of equipment to enhance recovery or recycling
options.
· Redesigning of equipment or production lines to produce less
waste .
· Improving operating efficiency of equipment .
· Maintaining strict preventive maintenance programme.
3.Production Process Changes
· Substitution of non-hazardous for hazardous raw materials .
· Segregation of wastes by type for recovery .
· Elimination of sources of leaks and spills .
· Separation of hazardous from non-hazardous wastes .
· Redesigning or reformulation for products to be less hazardous.
· Optimization of reactions and raw material use.
