8. TYPES OF WASTE ‹#› BIODEGRADABLE WASTE A biodegradable material can be defined as a material which can be decomposed by bacteria or other natural organisms and not be adding to pollution. Biodegradable wastes are such waste materials which are and can be degraded by natural factors like microbes (e.g. bacteria, fungi and few more), abiotic elements like temperature, UV, oxygen, etc.

9. NON- BIODEGRADABLE WASTE A Non-Biodegradable material can be defined as a kind of substance which cannot be broken down by natural organisms and acts as a source of pollution. Unlike biodegradable wastes, non-biodegradable cannot be easily handled. Non-biodegradable wastes are those who cannot be decomposed or dissolved by natural agents. They remain on earth for thousands of years without any degradation. ‹#›
