E- waste
E-waste or electronic waste is formed due to electronic gadgets such as computers, mobile phones, TV sets , etc . which are not in proper condition.
It is hazardous and unmanageable solid waste .
It contains many hazardous heavy metals such as lead , beryllium, mercury and cadmium.
These heavy metals are non-biodegradable in nature. Therefore , they remain accumulated in the environment and
remain there for a long period of time.
The solid microorganisms are directly and indirectly affected by E-waste.
E-waste affects the human health.
Burning and land filling of E-waste is dangerous for the surrounding environment and hence , disposing it becomes difficult.

Waste is a valuable resource, if managed properly, because:
Waste can be used for material recovery.
Through different processes like pyrolysis, gas and electricity can be generated.
The organic wastes can be used to produce bio-gas that supplies fuel and electricity.
Biodegradable wastes could converted into manures and bio-gas.
Variety of wastes, especially, non- biodegradable wastes can be recycled and reused in altered form.
