A note for Urban
Integrated Municipal Solid waste Management
A piecemeal approach and segmented work for the integrated
Municipal Solid waste management is a necessity for its
The total projects can be divided into two broad categories:
1. Waste Collection and transportation
2. Waste Processing and Disposal
Collection and transportation :
This component includes:
a) source segregation- primary segregation, IEC activity
b) Door to door collection and rag-pickers rehabilitation
c) Storage: transfer stations or direct in vehicles in bin-less
planning, or in bins.
d) Transportation Mechanized and technology managed.
Generally ULBs/Municipalities are experienced, have trained work
force and staff for this. There will be clash of interests in
transition including labor unrest. This needs to be synchronized
by city managers. Preferably O & M tenders should be separate,
with NGOs, local peoples and organizations. Mostly councilors are
Source segregation right at the kitchen level had to be done
with door to door waste collection to harness the waste properly
for its suitable management & treatment. The aggressive
Information and Education campaign ( IEC)is a must to be part of
The green waste and the construction waste, which has to be in
the scope of the work of O & M operators, is a necessity for their
accountability and cleanliness.
The road sweeping and drain cleaning, which also has to be in
the scope of the work of O & M operators, is also a necessity for
their accountability and cleanliness.
The bin less concept should preferably be introduced with waste
to be put directly in vehicles instead of in dhalaos/transfer
The littering of the waste in the vicinity of the town should be
stopped by law and law enforcing agencies. On the lines of the
Bombay municipal corporation private security agencies can be
hired for monitoring and imposing penalties.
System designing and integration has to be with waste processing
facility designers and operators.
Processing and Disposal
This component includes
1, Waste storages and segregation systems
2. Compost unit with or without vermiculture
3. Refuse Derived Fuel (RDF) unit with or without power generation
4. Engineered sanitary Landfill remediable after 25 years
5. Remediation of old waste land dumps and recycling facilities.
Not many companies has full expertise in this segment of
business, so any one activity with proper financial capability and
experience of executing these sizes of projects has to be primary
qualification criteria. This will get more bidders and at better
Systems have to be hi-tech, well integrated with current IT
This processing has links with carbon emission reduction, and
has to be incorporated. The advantage should be shared.
The recycling process components which are not original concepts
can be asked as additional capabilities and be part of qualifying
criteria in technical evaluation and negotiations.
Engineered sanitary landfills are highly technical work, need
expertise and experience. The material usages has to be ensured
and properly monitored by experts.
The waste processing units should insure only10 to 20% waste in
landfill and the life of 20 years and post closure maintenance of
10 years and then remediation should be a considering point.
Old waste Land dumps are a big eyesores in the city landscapes
and waste of these dumps keeps releasing toxic landfill gases in
the air and leachate in water bodies. These are always hazardous
for city life. The operators be permitted to process the
recyclables, biodegradable and inert waste as safe soil
