Simplifying Science:Presidium: Management of Non-Biodegradable waste...

The 3Rs

Day by day, hour by hour , the need for practicing '3rs' is increasing! We all are aware of the ill effects of the 'Non Biodegradable' wastes but how many of us are actually doing something about it??

The secong half of the chapter 'Garbage In, Garbage out' deals with the management of this type of waste. The 3Rs being-

REDUCE- we need to reduce the amount of waste generated by consuming more and throwing away less. We often buy more things than we actually need. Nowadays, disposable things are becoming very popular.

1 Use fountain pen instead of a ball point pen.

2. Use old newspapers for packaging.

REUSE- We can reduce the waste by reusing certain things for more than one purpose.

Small jars and bottles can be cleaned and use to keep other kitchen stuffs.
Old clothes can be made into usable items like cushion covers , handkerchief etc.

RECYCLE- The process by which waste materials are used to make new products is called recycling. Materials like glass, metals, plastic and paper are collected and recycled to make new things

We need to manage the usage of paper by following these 3 R’s because paper is made from trees and trees are essential for our survival on earth. So, though paper is biodegradable , the depletion of trees at a fast pace is a big concern. Therefore , to save trees we must use paper carefully.
