Solid waste and 3R principle – UGC NET Question

The 3R principle is a hierarchy that guides waste management towards sustainability. The most preferred option is to reduce waste generation at source, followed by reusing products to extend their life, and finally recycling materials so they can be processed into new products. This order minimises resource use and environmental impact. Hence, the correct sequence is Reduce, Reuse, Recycle, as given in option C.

Option A:
Option A is incorrect because it starts with reuse and places reduction later. While reuse is beneficial, preventing waste generation in the first place through reduction is considered even more desirable.

Option B:
Option B is incorrect since it begins with recycling, which, although useful, still requires energy and processing. Waste reduction and reuse are higher priorities as they avoid or delay waste creation.

Option C:
Option C is correct because it follows the established waste management hierarchy: first reduce consumption and waste, then reuse products, and finally recycle materials. This sequence aligns with environmental guidelines and UGC NET content.

Option D:
Option D is incorrect as it reverses the preferred order and again starts with recycling. Such a sequence does not reflect the principle of preventing and minimising waste before managing it.
