Solid Waste Management
Current Scenario- Experience
• Daily waste generation
— Municipal Solid Waste
: 7000 ton
— Construction & Demolition Waste
: 2500 ton
— Biomedical Waste (MPCB-Deonar) : 10 ton
— Hazardous Waste (MPCB-Taloja)
: 10 ton
— E-Waste (MMRDA-under planning) : 30 ton
• Unsegregated MSW collected, transported and unscientifically
dumped at Deonar & Mulund dumpsite
• 1900 vehicle trips daily collects Municipal Solid Waste
• Slum Adoption Scheme for regular collection of waste from the
slum areas

Solid Waste Management
cont’d
• Clean-up Marshal appointed for enforcement of ‘Greater
Mumbai Cleanliness and Sanitation Byelaws,2006’. Fine range
Rs 100 to 20,000
• People participation through 756 Advance Locality
Management (ALM) for management of local waste (25tpd)
• Dry-waste sorting centre managed by NGOs at ward level
(60 tpd)

Conventional Waste Management
Challenges
• Limited efforts on reducing waste at source
• Lack of segregation, poor collection, illegal dumping,
open dumping and burning of waste
• Limited involvement of private sector and
communities
• Considers waste having no value
• Relies on Landfills & Composting
• High cost of land in Mumbai city
• Green House Gas (Methane) generation

Sustainable Waste Management-Solutions
Solid Waste Management

•

Reduce, Reuse and Recycle (the 3Rs) offer an
environmentally friendly alternatives to deal with growing
generation of wastes and its related impact on human
health, economy and natural ecosystem
1. Reduce: Choosing to use items with care to reduce the
amount of waste generated at source
2. Reuse : Involves the repeated use of items or parts of
items which still have usable aspect
3. Recycle: Use of waste itself as resources
Resource recovery through waste processing
-- Biological Processes
-- Thermal Processes
Landfill Disposal: Dispose of items which cannot be used
by any means

MCGM Initiatives…
Solid Waste Management
• Kanjur (66 ha):
– Bioreactor (42 ha): 3000 tpd scalable upto 6500 tpd with no extra
capital works–Perpetual
– Composting (8 ha): 1000 tpd
– Landfill (7 ha): for 25 yrs, 250 tpd Process rejects & remnants

• Summary
– Out of total 7000 tpd MSW generation : 950 tpd recoverable
through MRF (Material recovery Facility)
– 6,500 tpd Processing facility scalable upto 10,000 tpd at short
notice
– Facility created can meet Mumbai need till total MSW
Generation reach 10,000 tpd
MUNICIPAL CORPORATION OF GREATER MUMBAI
Solid Waste Management
MCGM Initiatives…
• Landfill site will be available after 15 yrs at Gorai, Deonar & Mulund
due to stabilization of existing waste, which can be mined & sold
• New facilities at Kanjur, Mulund & Deonar will be in close shed, odour
& dust free, without any environment degradation or nuisance to the
neighborhood
• Output from waste:
- Compost
: 700 tpd
- Gas Generation
: 4000 cum/hr ~ 8 MW Power
- Recyclable/recoverable (RDF) : 950 tpd +
- Bioreactor mining after maturity (compost): 1200 to 2600 tpd

(Deonar 41 ha, Kanjur 59 ha, Mulund 4 ha)
• Plus additional land from Gorai, Deonar, Mulund dumpsite: 100
ha
MUNICIPAL CORPORATION OF GREATER MUMBAI
Solid Waste Management
Further Initiatives…
• Implementation of Dry waste sorting centers managed by
NGOs to accept the recyclables in each ward:
Estimated 250 tpd +
• Augmentation of Peoples participation through Advance
Locality Management (ALM) for residential associations and
decentralized processing of Houesehold / Green waste by
Vermin/Windrow composting : Estimated 200 tpd +

processing of Biodegradable waste in its premises by
Composting /Biomethanisation at Institutional Level
(Corporate/Educational/ Cultural/Health Institututes, Star Hotels, Housing/

LIQUID WASTE MANAGEMENT -Seven Sewerage Zones of Mumbai
Treatment
Action Plan
Challenges
I) Non compliance
of MPCB consent
standard
a) 880 Mld Sewage , plant at Colaba Worli and Bandra, will be
treated with suitable biological treatment taking into
consideration projected flow by 2031.
b)390Mld Sewage at Malad will be treated with suitable
biological treatment and 4km long Marine Outfall, taking into
consideration projected flow by 2031.
c) The Treatment as well as Pumping capacity will be
upgraded suitably to meet the requirement for the flow by
2031.
IV) Availability of
adequate land for
treatment facility.
1.New technology with smaller foot print.
2.Treatment with Stack arrangement.
3. Land required for Worli will be acquired by removing the
encroachment by way of SRA.
4)Land required for Bandra will be acquired from MSRDC
Coverage
Action Plan
Challenges
I) Coverage in
slums
1)Expansion of Sewerage networks
2)Due to paucity of place sewer lines cannot be laid
in slum areas and problem will persist. For this
Sewage from slums , will be collected by diversion
of flow from Storm water drains to Sewer line in Dry
season.
II) Unsewered
Area
Phase-wise expansion of sewerage networks
Action Plan – In Progress
1) Expanding existing network by conventional Open cut
method and Micro tunneling.
2) Replacing 5nos of existing satellite pumping stations.
3) Construction of new Influent and Effluent pumping
stations at Two places in Mumbai ‘s Western suburbs
Malad and Versova.
4) Conditional assessment and rehabilitation of 25Kms of
Man –entry Sewers.
5) Construction of about 13Kms long Collector Tunnel in
Western suburb .
6) Construction of 5km long two transfer tunnel in Western
suburb.
Cont’d
7) Construction of 3.9M dia x6.0Km long Marine
outfall in Western suburb.
8) Improving level of Sewage Treatment at all 7
locations ,so as to achieve 20mg/litre BOD and
30mg/litre SS in creek/Harbour and
100mg/litreBOD and SS in West coast.
* The Consultants for the works at s.no 2 to 8 are in place and their
BODR are ready for invitation of bids ,so as to complete these works
by end of 2017.

Mangroves Protection :
Introduction
• Ministry of Environment & Forest, Govt. of
India vide notification S.O.19(E) dated 6th
January 2011 published the new Coastal
Regulation Zone (CRZ) Notification 2011.
• The
CRZ
notification
regulates
the
development so as to protect the natural
coastal
barriers
like
reefs,
dunes,
mangroves,
beaches
and
terrestrial
vegetation.The CRZ are classified into 4
categories (i.e CRZ-I, CRZ-II, CRZ-III & CRZIV).
….contd.
• CRZ - I covers ecological sensitive areas
like Mangroves, mudflats, sand dunes
etc…..
• Mangroves are one of the important
geomorphological landforms in coastal
ecosystem.
• As per the CRZ Notification in case of
Mangroves area more than 1000 sqm. a
buffer of 50 m along the Mangroves is to
be maintained.
….contd.
• All mangrove areas are to be mapped and
notified as protected forest and necessary
protection and conservation measures for
the identified mangrove area is to be
initiated.
• Five times the number of mangroves
destroyed/cut during the construction
process shall be replanted.
• It is in form of trees and shrubs of varies
species with several families, mostly found
with seawater and around tidal influenced
bodies, likes creeks, estuaries, wetland etc.
Mangroves: Silent Coastal
Saviors
•Halophytic plants that grow at interface between soil and water
•Evolved around 114 million years back
•Mangue- Into the sea Groves- Garden/Forest
IMPORTANCE
• Protection to shoreline
from seawaves,
Cyclones
• Nursery for marine
fauna
• Living for fisherfolks
• Construction & timber
• Carbon Sinks
• Ecological balance
• Research
• Education
Conservation of Mangroves
• Hon’ble high Court of judicature of Mumbai has
directed the State Coastal Zone Management
Authority to carry out the satellite mapping of
mangroves of the state of Maharashtra for their
protection and conservation.
• Accordingly Maharashtra Pollution Control Board,
Mumbai has entrusted the studies “Satellite
mapping of mangroves of Maharashtra” using two
data IRSP6, AWiSF data under phase-I to
Maharashtra
Remote
Sensing
Application
(MRSAC)Center, Nagpur.
• All the mangroves area have been declared as
Protected Forest by State Government of
Maharashtra.
Our Role In Mangrove
Conservation
• Understand mangroves
• Conduct & encourage research
• Prevention of tree cutting
• Watch on neighbourhood areas
• Follow up ‘3R Principle’
• Participation in conservation
activities
