Which one of the following is NOT included in the 'three Rs' of solid waste management?
AReduce
BRecover ✓ Correct
CRecycle
DRe-use
Correct answer: (B) Recover
Explanation
Recover is not one of the three Rs, which stand for reduce, reuse and recycle in solid waste management.
Reduce is a genuine R that cuts waste at the source by using less.
Recycle is a genuine R that reprocesses materials into new products.
Re-use is a genuine R that puts an item to use again without reprocessing.
Recovery of energy or materials is a further step, distinct from the core three Rs.
Following the three Rs in order lessens the volume of waste sent to landfills.
