We generate following wastes at home, school or other places:
(a) Our home waste contains kitchen waste, plastic items, broken metals, glasses, newspapers, old books, etc.
(b) In school, our waste contains papers, chalk pieces, polythene, left over food, pens, etc.
© When we visit tourist places, we generate wastes like polythenes, wrappers, disposable plates, glasses, spoons, etc.
We can reduce most of the waste from the above list by categorising and separating them as biodegradable (i.e. paper items, food waste, wood, etc.) and non-biodegradable, (i.e. plastic, glass items, metals, etc.) Biodegradable waste is decomposed easily by microorganisms in nature and much of this waste is reduced easily. Non-biodegradable waste is difficult or rather impossible to reduce as. it cannot be decomposed by microorganisms in nature.
