Question

What do you mean by the ’4R principle’ to develop environment friendly habits?

Answer 1

Answer:

The 4R means Reduce, Reuse, Recycle and Restore.

(i) Reduce: We should reduce the use of non-biodegradable compounds that are harmful to us.

Example: Instead of using polythene bags we should give preference to paper bags.

(ii) Reuse: We should reuse the materials instead of dumping.

Example: Plastic bags can be reused to make decorative things.

(iii) Recycle: Non-biodegradable materials should be subjected to the recycling process.

Example: Plastic materials.

(iv) Recovery: If the waste remains after it is been reused and recycled, we can use it to generate energy at our waste-energy (EfW) plant. This is known as Recovery.
