Question

Yes there are Four. I will elaborate at the close of this question.
Please list and explain any that we don't normaly consider ie. the fourth. Thanks

Answer 1

Recycling is just one way to reduce wastes. To be really effective, we have to incorporate the 4Rs Reduce, Reuse, Recycle and Recover into our daily routine.

Reducing the amount of waste we produce is by far the most effective way to battle the flow of garbage into the landfill. Packaging makes up about half our garbage by volume, one-third by weight.
What we cannot Reduce we should try to Reuse.

Finally, Recover energy from wastes that cannot be used for something else. This fourth R is difficult to put into practice by individuals, and is geared more toward industry.
