as a substance which is of no use. Waste that we see in our
surroundings is also known as garbage. Garbage is mainly considered

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.

11. Recycling
Recycling means separating usable materials
from waste and converting them into new
products.
Paper can be recycled to make newspaper,
toilet paper,etc. Iron, copper, aluminium,
