towards sustainable organic waste disposal ~
Present Status ~ Garbage Collection &
Disposal System ~
percentage of Garbage resident communities generate, is picked
up from house or establishment by the sweeper and dumped at nearby
community bin (termination point of primary collection) for onward
transportation to notified dumping ground (termination point of
secondary collection). MCGM have been able to cover few areas
where Garbage is picked up house-to-house and brought directly
to dumping ground. In addition, some quantities of Garbage are
brought to notified dumping ground through transfer station.
Impact of Present Waste Disposal System ~
community bins & dumping sites become eye sore, cause foul
smell, become breeding places for harmful bacteria & attracts
diseases carrying vectors such as flies, mosquitoes, birds, rats,
situation gets bad-to-worse when this garbage enters into water
bodies during monsoon, reviving unpleasant memories of loss of
life & moveable asset during recent deluge on 26th
July. The prime concern arising out of present waste disposal
system is its impact on community health & environment. No
matter who owns the responsibility of garbage disposal, realty
is that resident communities are the victim of their own apathy
towards sustainable solution to the problem.
opportunity cost of using space in Mumbai for garbage dumping
is very high. Apart from land being costly & finite resource,
judicial activism on use of land near water bodies is compelling
Municipal Administrators to move towards enforcement of waste
segregation and encourage community initiative towards waste minimization
& recycling at source of generation.
MCGM initiatives ~
has made it mandatory for every household to segregate wet waste
and dry waste with a view to facilitate efficient waste composting
& recycling near to waste generation. MCGM has taken initiatives
to encourage successfully operating garbage disposal system at
source of generation.
There are decentralizing small scale source
disposal options for Segregated Organic Waste successfully operating
but with limited presence. Such models have possibility of multiplication
with public private partnership ~
BARC Model ~ Nisergruna Biogas Plant ~
Excel Model ~ Organic Waste Converter (OWC) ~ Annexure:
offer decentralized solution for treatment of Segregated Organic
minimize haulage of waste to long distance landfill site
facilitate reduction of landfill space requirement
promote stakeholders participation for Organic Waste Segregation,
treatment and potential use of output for Greener & Healthier
User Groups of decentralize disposal options:
Community Cluster of minimum 1000 families in 200 meter
radius with availability of open public area for curing of treated
~ Building Cluster in
waste generators generating minimum 500kg of Segregated Organic
Waste per day with availability of open Public area for curing
of treated material.

Power Segregated Organic Waste Capacity
20kg per batch / 500kg per day per shift
50kg per batch / 1000kg per day per shift
13.5 HP 120kg per
batch / 3000kg per day per shift
volumes of food waste from pre-cooking, leftover after meal are
dumped in community bins, which is responsible for foul odour
& health hazards. Organic Waste Converter homogenizes organic
waste with appropriate additive & bio culture. The output
from device is uniform coloured coarse powder in appearance and
is without any bad smell. Thus treated material over come major
cause of nuisance to resident community related to eye & nose
sense and can be composted into good quality organic manure in
2 weeks of curing period.

Project Revenue Model Options ~
Cost subsidy from MCGM

and authorization to Operating Agency to raise remainder of minimum
monthly billing amount from community or bulk user group on pay

Nominal lease rent of Rs. 1 per annum
The suitable mechanism for recovery of pre-determined monthly
charges and site specific primary collection cost will be decided
by Municipal Authority.
Operating Agency will not be obliged to treat mixed waste
received at the treatment facility.
Average Organic Waste Generation by community @ 100gm per
capita per day is estimated and family unit of five persons assumed.
Waste Converter plan suggested by Mr. Rishi Agrawal
Five units are
operational in Mumbai. All units are in private premise. The user
categories are Multistory Apartment Bldg, Club Premise,
, Corporate Office Canteen.
areas where the plan can be rolled out.
Cluster of Hotels
Airport adjoining area
Cluster of Hotels
is substantial waste being generated in Lokhandwala Complex and
if an Organic Waste Converter (OWC) is set up here then a organic
waste from this area would not enter the conventional waste stream
ending up in Gorai or Deonar.
in Hotels organic waste is generated in bulk, in a single source
and available largely in a segregated form.
like Lokhandwala Complex Environmental Action Group can play a
role in neighbourhood mobilisation and also actively manage the
meeting: In the case of a housing complex like Lokhandwala Complex
it will involve building-to-building meetings.
In the case of the Airport area it will involve meeting
need to ascertain from SWM Dept:
The quantum of
waste being generated
Whether it is
segregated with the organic/wet component being available separately.
the waste is segregated then we can directly talk in terms of
processing the waste. If the waste is not segregated then we will
have to undertake measures to ensure segregation.
BMC will play
a very critical role in this exercise by fundamentally accepting
decentralized waste management and support entities, which take
up decentralized waste management (DWM).
Various agencies of the BMC will then have to do their
bit in forwarding DWM.
1.BMC will have
a) provide 3mt x 4mt
cabin space with power connection for the Organic Waste Converter.
b) permit curing of
treated waste in nearby Public area.
c) deliver segregated
organic waste at OWC facility
BMC will have to agree to the rate to be paid to operating agency
for treating organic waste in the decentralized manner.
