2. What is waste?
• Waste includes all items that people no
longer have any use for, which they either
intend to get rid of or have already
discarded.
• Additionally, wastes are such items which
people are require to discard, for example
by lay because of their hazardous
properties.

3. EXAMPLES
• household rubbish, sewage
sludge, wastes from
manufacturing activities,
packaging items, discarded
cars, old televisions, garden
waste, old paint containers etc.

4. Types of wastes
• Municipal Waste (including Household
and Commercial)
• Industrial waste (including
manufacturing)
• Hazardous Waste
• Construction and Demolition Waste
• Mining Waste

5. ...
• Waste from Electrical and Electronic
Equipment (WEEE)
• Biodegradable Municipal Waste
• Packaging Waste
• End-of-Life Vehicles (ELVs) and Tyres
• Agricultural Waste

8. Facts and figures
In INDIA,
Solid waste – 30 million tonnes/year
Liquid waste – 4400 million
cubicmetres/year
Municipal solid waste-
0.25 to 0.66 kg/person/day (avg.
45).

9. Method of waste treatment
• Landfill- burying the waste.
• Incineration- burning the waste
to residue and gaseous products.
• Energy recovery- using it as a
mean to generate energy.

10. Technologies of waste
recovery

11. Anaerobic digestion/
biomethanation
1. anaerobic biodegradation of wastes.
2. production of biogas & effluent.
3. generation of power through turbines &
engines.
4. also used as soil conditioner & manure

12. Combustion/Incineration
• Burning of wastes in presence of oxygen at
high temperature (around 800ºC).
• Generated heat(steam) is used in turbines to
produce power.

13. Landfill Gas recovery
• Organic fractions of waste slowly volatilizes
and decomposes to produce landfill gases.
• The gas contains a high percentage of
methane (about 50%).
• Used for direct heating/cooking applications.

14. Pyrolysis/Gasification
• Organic material is heated in absence of air
until the molecules thermally break down to
become a gas comprising smaller molecules.
• The gases produced by pyrolysis mainly
comprise carbon monoxide (25%), hydrogen
and hydrocarbons (15%), and carbon dioxide
and nitrogen (60%).
• Gases are used in I.C. engines & turbines.
