be used reduced to make compost
• Minimize the effect of hazardous or nuisance wastes
on the community
• Reduces waste disposal

12. ADVANTAGES OF
RECYCLING
• It helps in conserving the natural resources
• Helps in reducing the pollution that may come up due to disposal of waste
materials
• Recycling helps to limit the amount of glass, paper and plastic that must be
produced
• Makes people environmentally aware
• It saves space in landfills. The items that we recycle are not biodegradable.
• By saving energy you are cutting down the amount of CO2 being added to the
greenhouse gases already in the atmosphere. So you are slowing down global
warming.

13. Reusing of waste
•Converting old pieces of cloth into
doormats, cushions etc
•Fly ash from power plant is used to
make cement substitute, bricks
•Many waste material serves as raw
material for handicrafts.

15. Governments initiative in waste
management
• Both central & state government takes up the
responsibility of sustaining the environment &
proper waste management.
• Implementing schemes & laws for environmental
protection.

16. Government initiatives (facts)
• Indian urban areas • Potentially 1700 mw

million tonnes of solid generated from urban
waste & about 4400 & municipal waste and
million cubic meters about 1000 mw from
of liquid waste every industrial waste
year

17. Governmental environmental
policy
• Not building large dams for
hydroelectric power generations.It leads
to submergence of normal land and
displacement of people.
• Checking degradation of land & water
through wasteland management
• Making laws of environmental
protection THE ENVIRONMENT (PROTECTION) ACT, 1986
• Conserving natural resources by making
reserved forests & biosphere reserves

18. Disadvantages:

..Forests and wildlife are damaged in
the beginning of the project

..the original river is often diverted and
then down-river may be horribly
effected by the change in course
..Arable land is
eaten up by the
newly created lake.

19. Role of the government in improving the existing
technologies
• Using CNGs in the automobiles to reduce vehicular
pollution
• Setting up National waste
Management Council
• to manage solid waste

20. Strategies for waste management by the high-powered
commission(1995)
• Encouraging residents to segregate the waste
• Vehicle for transporting waste MSW(municipal solid
waste) to be covered so as not to litter & pollute the
environment
• Hazardous waste (management & handling)
• Banning the usage of plastics and polybags
• Bio-medical waste(management & handling) :
segregation, disposal, collection &treatment

21. Social
initiatives
