3. Waste minimisation: is the process and the policy of reducing the amount of waste produced by a person or a society.
6. Negatives:· Large amount of air pollution and ash generated · Generation of hazardous residues · Large impact on surrounding communities that must deal with unpleasant side effects · Loss of potential recyclables · Large investment required and long lead time before operation
8. Positives:You can get money for what you recycle (aluminum just about everywhere, and places that have CRV tax you get it back, sometimes up to $.10 a bottle, etc) You reduce the amount of resources needed to make the same item compared to making it without recycling It saves natural resources as it takes less energy to make something with recycled material rather something new It saves space in landfills. The items that we recycle are not biodegradable.
9. Negatives: Causes people to buy more waste because they feel good for recycling. For example, plastic bags in supermarkets and such. Its inconvenient (you have to wash all the products that had sticky substances in them (coke can)In some areas you have to pay to have your items recycled at home and its illegal not to recycle and its a hassle to drive to the nearest recycling plant and it costs gas + the plastic bags you need to store the recycled items in.

12. · Costs tend to drive the building of regional mega-landfills which excite intense opposition from host communities
13. · Release high concentrations of methane and water pollution
20. The 3Rs It calls for an overall reduction in resources and energy used, increase in the ratio of recyclable materials and further reusing of raw materials and manufacturing wastes.
21. The 3Rs in India Characteristic of India: A higher proportion of small and very small quantity generators Implication: More difficult to control waste movements arising from such generators and more difficult for such generators to initiate waste reduction measures
25. Biomethanation: biogas -A biomethanation plant to process 500 tonnes of waste per day will be set up at Mulund, Mumbai -Responsible for 5% of city’s electricity
