Question 3(c)

Give a reason for each of the following:

(i) Recycling of waste to produce paper can reduce deforestation.

(ii) Sugarcane waste can be recycled into useful products.

(iii) We should avoid using polythene carry bags.

Answer

(i) Recycling of waste to produce paper can reduce deforestation as in India, we have tonnes of bagasse from sugarcane during a particular season. Bagasse is used in the manufacture of paper pulp and this helps to save trees which are normally used for making paper pulp.

(ii) Bagasse is a waste product from the sugar industry. In India, we have tonnes of bagasse from sugarcane during a particular season. Bagasse is used in the manufacture of paper pulp and this helps to save trees which are normally used for making paper pulp. Bagasse is also used for making packaging material for dairy products. Hence, sugarcane waste can be recycled into useful products.

(iii) We should avoid using polythene carry bags because plastic is non-biodegradable. Plastic has to be incinerated, recycled or buried in landfills. The polythene carry bags are made from recycled plastic. They are harmful because the melting of plastic and plastic products breaks some polymer chains into smaller units which are harmful.
