Question

why should bio degerdable and non bio degerdable discarded in two seprate dustbin

Answer 1

Bio degradable substances should discarded in separate dustbin as there is a lot of use by it. We can use most of it (onion peel, etc) as a fertilizer that helps the plant to grow easily. We cn make compost pit. Through this biodegradable waste, the soil gets fertility. Increases water rentention in soil.

               Where as non biodegradable substances are harmful to the environment. So, we can use 3R principle here. Reuse, Reduce, Recycle. Most of the non biodegradable substance can recycle and use such that it doesnt show any impact on environment.

Answer 2

Bio degradable are something which can be degraded easily such as vegetable peels whereas non bio degradable are those which can't be degraded like plastic covers.
     If the bio degradable and non bio degradable are discarded in the sane dustbin then the animals which feed on them such as cow, buffalo etc will be suffering with some infectious diseases. Since plastic covers contain some harmful material in it. So, bio degradable and non bio degradable are discarded in two different dustbins. Every one should follow this process.
