Question

What are biodegradable and non biodegradable materials with examples?

Answer 1

Answer:

Explanation:

✔✨Biodegradable Waste:

Those waste materials which can be broken down to non-poisonous substances in nature in due course of time by the action of micro-organisms like certain bacteria, are called biodegradable waste. A biodegradable waste decomposes naturally and becomes harmless after some time.

Cattle dung and compost are common examples of biodegradable waste. Other examples are animal bones, leather, tea leaves, wool, paper and wheat. Many of the industrial wastes are also biodegradable. All the biodegradable industrial wastes should be treated to make them harmless before dumping them into soil or water.

✔✨Non-biodegradable Waste:

The waste materials which cannot be broken down into non-poisonous or harmless substances in nature are called non-biodegradable waste. Examples are plastics, polythene bags, ball-point pen refills, synthetic-fibers, and glass objects, metal articles like aluminium cans, iron nails, silver foil and radioactive wastes.

All these non-biodegradable wastes cannot be made less poisonous easily and hence they are major pollutants of the environment. These wastes cannot be decomposed by micro organisms like bacteria.
