REUSE:We should reuse things like plastic bags can be used to make decorative things.
RECYCLE:We should give waste things (which cannot be decomposed) for recycling.like plastic materials.
RECOVER: If there is still waste left over after we have reduced, reused and recycled as much as we can, we can use it to make energy at our energy-from-waste (EfW) facility. This process is known as Recovery.
