Question

what ard 4R,,s principals

Answer 1

REDUCE


Waste reduction (or prevention) is the preferred approach to waste management because waste that never gets created doesn't have any associated waste management costs

REUSE


Reuse is not recycling, because recycling alters the physical form of an object or material. Reuse is generally preferred to recycling because reuse generally consumes less energy and resources than recycling. Waste is defined as material for which no use or reuse is intended. Thus, reuse prevents objects and materials from becoming waste.

RECYCLE

Recycling is not waste prevention because only waste can be recycled. One must generate waste in order to recycle the waste. Therefore, if you are recycling, you have already generated waste. Although recycling is a very good thing, ideally it would be better to not generate any waste.

ROT

The biological decomposition of organic materials such as leaves, grass clippings, brush, and food waste into a soil amendment.
