Question

Match the following 4R principles with their meaning.

• A. Minimum use
• B. Use again
• C. Process and use
• D. Reclaim

Answer 1

The 4 R principles are: reduce, reuse, recycle and recover.

Reduction of use of plastics reduces the generation of non eco-friendly waste, in the first place.

Reusing the same product increases its life. For example, your school books can be reused by someone else, after you get promoted to the next grade.

Recycling reduces the amount of raw materials needed for any industry in the first place. For example, recycling paper can reduce the amount of wood needed. Thus, it will reduce deforestation.

Recovery reduces the use of natural resources. For example, non-recyclable waste can be used as a fuel to heat water and make steam, which powers the turbine to produce electricity.
