Question

Being a responsible citizen, we have to develop habits that are environment friendly. What is the 4R principle we all should follow?

• A. Refine, reuse, reduce, and respond
• B. Reuse, refine, recycle, and recover
• C. Reduce, rethink, refine, and recover
• D. Reduce, reuse, recycle, and recover

Answer 1

The correct option is D Reduce, reuse, recycle, and recover

• Reduction in the use of plastics brings down the production of non-ecofriendly waste.
• Reusing the same product further reduces the accumulation of waste.
• Recycling reduces the number of raw materials required for any industry.
• Recover refers to the conversion of leftover waste into other resources such as electricity, compost, etc. through thermal and biological processes.
