The document discusses the 3 R principles of waste management - reduce, reuse, and recycle. It defines each principle and provides examples. Reduce means not producing unnecessary waste in the first place. Reuse involves using an item again without processing, like donating or selling second-hand items. Recycling turns waste materials into new products, saving resources. The document provides tips for reducing, reusing, and lists many items that can be recycled like paper, plastic, electronics, and construction waste. It concludes that reducing waste is important to save money and resources and protect the environment.

•To reduce pollution
•It costs your pocket(Rs.1500 to Rs.2000 per Tonne)
•An expected 50% increase in the next 10 years

10. •for every ton of paper that is recycled, the following are saved:
•17 trees
•60,000 gallons of water
•225 kilowatt hours
•3.3 cubic yards of landfill space
•Energy used to recycle paper is close to 70% less than when paper is prepared using virgin wood and other raw material.
•Almost every hour, nearly 250,000 plastic bottles are dumped. Plastic bottles constitute close to 50% of recyclable waste in
the dumps.
•The average time taken by plastic bottles to decompose in a landfill is close to 700 years
• India recycles roughly 40 percent of their e-waste a year. This includes such items as broken or unwanted electrical
appliances.
•8,500 mobile phones, 5,500 TVs and 3,000 personal computers are dismantled in Delhi every day for reuse of their
component parts and materials. In the capital alone, it is estimated that over 1,50,000 workers are employed in official and
unofficial e-recycling units.
