Three 'R mantra': Reduce, Reuse and Recycling are three 'R mantra'.
'Reduce' means using fewer resources in first place. Instead of throwing things away, trying to find ways to use them again is 'Reuse'.
Recycled items are put through a process that makes it possible to create new products out of the materials from the old ones. Reducing, reusing and recycling cut the amount of energy used to provide new items and amount of pollution generated as result. It also conserves valuable natural resources that would otherwise be used to produce new items from raw material.
