is unwanted or useless material left over after an activity.
Waste is also known as trash,refuse,rubbish,garbage and junk. Waste is directly
linked to human needs. Most human activities, specially related with industrial
development and innovation, manufacturing, use of manufactured products, etc.,
lead to waste generation.

following types on the basis of source of its generation.
1.
Domestic waste
2.
Industrial waste
3.
Agricultural waste
4.
Commercial waste

Segregation of domestic waste into
biodegradable and non biodegradable waste:
On the basis of degradation of materials in nature, the
waste materials can be broadly classified into two types- biodegradable and
non-biodegradable.
Biodegradable waste material:
The waste materials that can be broken down or
decomposed into simpler harmless substances
in the nature in due course of time, by the action of microorganisms, such as
bacteria are called biodegradable waste materials.
Non-biodegradable waste materials:
The waste materials that cannot be decomposed to simpler
non-poisonous substances in the nature by the action of microorganisms are
called non-biodegradable waste materials.
