Circular economy material loops – UGC NET Question

A circular economy aims to move away from a linear “take make dispose” model toward closed material loops. Recycling is a core strategy that transforms used materials into inputs for new products. The stem lists reuse,repair and remanufacturing and asks for the missing process that keeps materials in use,which is recycling. Hence Option B is correct.

Option A:
Landfilling is a disposal option that removes materials from productive use. It is characteristic of the linear economy rather than the circular one,so Option A contradicts the intention of the question.

Option B:
Recycling allows materials like metals,glass and many plastics to be recovered instead of discarded. Combined with reuse and repair,it helps minimise raw material extraction and waste. This fits perfectly with the circular economy logic in the stem.

Option C:
Incineration destroys materials through burning and usually reduces opportunities for material recovery. Even when energy is recovered,it is not considered a core loop-closing process in circular economy thinking,so Option C is not ideal.

Option D:
Exporting waste often shifts environmental burdens to other regions and does not ensure that materials are effectively looped back into production. Thus Option D does not capture the principle in the question.
