The three R’s 

Recycling is the process of collecting and processing materials that would otherwise be thrown away as trash and turning them into new products.

In general consumption of goods, however, we ignore the fact that a major portion of our waste can be reduced or reused before resorting to recycling.

It would be very responsible of us if we could reduce the consumption of products to the maximum extent possible. So, the three R’s of sustainability are Reduce, Reuse…and then Recycle.
