Define the 4R Principle in Brief

Answer: Reduce, reuse, recycle, and recover garbage are all part of the 4-R approach for proper plastic use. The 4-R rule is a garbage and waste stream management strategy that is environmentally sustainable. It divides a waste stream into incremental fractions for reduction, reuse, recycling, and recovery.

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

(i) Decrease: We should reduce our use of dangerous non-biodegradable substances.

For instance, instead of using polythene bags, we should use paper bags.

(ii) Reuse: Instead of dumping the materials, we should reuse them.

Plastic bags, for example, can be reused to manufacture beautiful items.

(iii) Recycle: Non-biodegradable materials should be recycled as much as possible.

Plastic materials, for example.

(iv) Recovery: If there is any garbage left over after it has been reused and recycled, we can use it to generate energy at our waste-to-energy plant. This is referred to as “recovery.”
