aim• Three Rs aim to generate minimum amount of waste and to extract maximum benefit from the waste generated & produced
Reduce the use of harmful products eg.. Polybags etcPromoting awareness amongst the humans towards judicious use of theproducts to reduce waste generationLearning to use the products which are eco-friendly & biodegradableHousehold waste (vegetable peels, garden waste) can be used reducedto make compostUsing washable napkins instead of paper napkinsDisposables like plastics plates, plastic food storage bags must not bethrown away as they last for a long time and can be put to many uses
• Promoting awareness amongst the humans towards judicious use of the products to reduce waste generation• Learning to use the products which are eco-friendly & biodegradable• Household waste (vegetable peels, garden waste) can be used reduced to make compost• Minimize the effect of hazardous or nuisance wastes on the community• Reduces waste disposal
• Processing the waste into raw materials usable in other useful products• Recycling becomes possible if the waste is segregated, cleaned & reprocessed into new useful products• Recycling is beneficial only if the cost of reprocessing is recovered by the demand of the product

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.

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.
Government initiatives (facts)• Indian urban areas • Potentially 1700 mw generate approx 30 of power can be 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
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
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.
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
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
Social initiatives• Involvement of Various • Using the services of the rag organizations & NGOs pickers in segregating the creating awareness about waste & help and train reduction & recycle them to convert organic waste into manure(organization: Stree• Awareness programme mukti Sangatna) organized on the topics of judicious use of resources & products like electricity , water etc • Organizing exhibitions, public meetings & rallies to spread awareness on recycling of products
