Explanation:

The principle of reducing waste, reusing and recycling resources and products is often called the "3Rs."

Reducing means choosing to use things with care to reduce the amount of waste generated.

Reusing involves the repeated use of items or parts of items which still have usable aspects.

Recycling means the use of waste itself as resources.

Waste minimization can be achieved in an efficient way by focusing primarily on the first of the 3Rs, "reduce," followed by "reuse" and then "recycle."
