Solid waste management involves the collection, treatment and disposal of solid waste. The document discusses various aspects of solid waste management including definitions of solid waste and SWM. It describes sources and types of waste as well as common collection and disposal methods like landfilling, incineration, compaction and pyrolysis. A case study on SWM in Mumbai outlines the waste generation, collection processes and disposal methods used. The objectives and importance of effective SWM are also highlighted.

3. What is Solid Waste?
non-liquid ,non soluble materials ranging from municipal
garbage to industrial wastes that contain complex and
sometimes hazardous substance
Examples: plastics, Styrofoam containers, bottles,
cans, papers, scrap iron, and other trash, etc.

4. Sources of Wastes:
Households
Commerce and
Industry

5. Agriculture
Fisheries

6. Collection of solid waste:
 Collection of waste includes gathering the waste,
transporting to a centralized location and then
moving it to site of disposal
 Then collected waste is the separated.

7. Types of solid waste:

8. Hazardous waste:
Hazardous waste are the types of waste which are
harmful for human beings.
E.g.:-solvents acids, heavy metals,pesticides,etc.

9. Non-Hazardous waste:
Non Hazardous waste are the types of waste which
are not harmful for human beings.
E.g.:-garbage, sludge, municipal trash.

10. What is meant by solid waste
management?
Solid Waste management is the
"generation, prevention, characterization,
monitoring, treatment, handling, reuse and
residual disposition of solid wastes".

11. SOLID WASTE MANAGEMENT-Objectives
 Public hygiene and health
 Reuse ,Recovery and Recycle
 Energy generation
 Sustainable development
 Aesthetics

12. Methods of solid waste management:
• LAND FILL
• INCINERATION
• COMPACTION:
• PYROLYSIS:-
• The 3 R’s

13. 1.LAND FILL:
 It is the most traditional method of waste disposal.
 Waste is directly dumped into disused quarries,
mining voids or borrow pits.
 Disposed waste is compacted and covered with soil
 Gases generated by the decomposing waste
materials are often burnt to generate power.
 It is generally used for domestic waste.

15. 2. INCINERATION:
 Incineration is a waste treatment process that
involves the combustion of solid waste at 1000C.
 waste materials are converted into ash, flue gas,
and heat.
 The ash is mostly formed by the inorganic
constituents of the waste and gases due to organic
waste.
 the heat generated by incineration is used to
generate electric power.

17. 3.COMPACTION:
 The waste is compacted or compressed. It also
breaks up large or fragile items of waste.
 This process is conspicuous in the feed at the back
end of many garbage collection vehicles. Deposit
refuse at bottom of slope for best compaction and
control of blowing litter.

19. 4.PYROLYSIS:
 Pyrolysis is defined as thermal degradation of
waste in the absence of air to produce char,
pyrolysis oil and syngas, e.g. the conversion of
wood to charcoal also it is defined as destructive
distillation of waste in the absence of oxygen.
External source of heat is employed in this process.

21. 5.The 3 R’s:
 REDUCE
 REUSE
 RECYCLE

22. REDUCE:
 You can help by PRECYCLING. 1/3 of all garbage is
packaging.
 Buy things that are in packages that can be recycled or
are made of recycled materials.
 When you buy something small, say no thanks to a bag.

23. REUSE:
 Many things can be reused before you throw them out.
 Use coffee cans and cottage cheese containers for storage
 Put leftovers in resalable containers instead of using wraps
and foil
 Use old clothes as rags for cleaning instead of paper towels
 Have a garage sale or donate clothes, books or toys that you
don't use anymore

24. RECYCLE:
 Each year we use:
 25 billion plastic containers
 30 billion bottles & jars
 65 billion aluminum cans
 100 billion pounds of paper

25. Case study
 Location: Solid waste management in Mumbai,
Maharashtra
 Capital of Maharashtra
 Greater Mumbai consist of ‘island city’ and
suburbs;area:437.71 sq km (MCGM 2013);under
single municipal administration

26. General profile:
 Population of city around 12 mn
 41.3% of total urban households live in slums
 Climate :moderately hot ,humid almost through
the year

27. Waste collection:
 Agency in charge is MCGM or BMC
 Garbage generated in 2012-2013 is 9200 metric ton
 Street Sweeping – 100% street cleaning in 1 or 2 shifts
(67% by municipal staff and 33% roads by private
contractors)
 Collection 83% through collection bins and 13% house-
to-house collection (Source: MCGM)
 Frequency :
 1396 number of trips each day. (MCGM

28. Waste Collection Pilot schemes:
Advanced Locality Management
(ALM) –
• Street communities interact with
Ward officers; for civic issues like
promoting
• rag-pickers for dry waste collection
and composting for wet-waste

29. Waste Management Framework:
Stakeholders
Institution in
Charge –
Municipal
Corporation
of Greater
Mumbai
(MCGM )
Informal Rag-
pickers and
Recyclers
NGOs and
recycling
companies
Citizens

30. Waste Disposal - Journey of Waste…

31. Methods of landfill
 Area method
 Trench method
 Open pit method
 Canyon method.

32. Area method
The area method is used when the terrain is unsuitable for
excavation.
The filling operation usually is started by building an
earthen levee against which wastes are compacted and
placed in thin layers.
At the end of each days operation a 150-300 mm of layer of
cover material is placed over the completed landfill.
A completed lift, including the cover material is called a
cell

34. CONCLUSION:
 Solid Waste Management is one of the important
functions of urban local bodies.
 It is observed that lack of financial resources,
institutional weakness, improper selection of
technology, transportation systems and disposal
options are making this problem even worse.
 Increase in population has increased all sorts of
demands leading to formation of wastes.
 If ignored, this problem may lead serious hazards and
hence this topic is burning issue.
