Question

Why should we segregate different types of wastes ? Give advantages of a twin bin system.

ANSWER :

First ,

meaning of word-

SEGREGATE : To divide, to separate

It is important to segregate different types of wastes because -

There are two different types of wastes,

1. Bio-degradable wastes : The word usually mean, bio = living organisms, degradable = decomposable. So, it means that the materials which can be broken down into simpler substance by micro-organisms are called bio-degradable wastes.

Examples : Paper, Clothes, Vegetable wastes, Cardboard etc.

2. Non bio-degradable wastes : The materials which cannot be broken down into simpler substances by micro-organism are called non bio-degradable wastes.

Examples : Poly bags, Batteries, Glasses etc.

So,

If we mix both bio-degradable wastes and non bio-degradable wastes, the non bio-degradable wastes will not decompose and cause soil pollution as they cannot be broken down into simpler substances by the micro-organisms.

Therefore,

It is good to separate the wastes differently.

To separate both wastes Twin Bin System can be applied.

Twin Bin System :

• There would be two different bins.

• The BLUE COLOURED BIN : where the biodegradable wastes would be thrown.
• The RED COLOURED BIN : where the non biodegradable wastes would be thrown.

Now,

Advantages of twin bin system :

1. The biodegradable wastes and non biodegradable wastes will be separated.
2. The biodegradable wastes can be used for making compost.
3. The non biodegradable wastes can be taken for recycling.
