The waste materials rot easily and mix with soil. Micro-organism , such as bacteria , fungi and earthworms help to decompose such waste.
Non-biodegradable waste materials do not rot easily .They do not mix with the soil and remain in the environment for a long time.

Waste is first collected at one place and
then burnt . Chemicals and other
poisonous waste is burnt in a large furnace
. This is harmful and causes air pollution.
Waste is loaded in trucks . It is
then taken far away from the
town or city and dumped in the
open . Disposing of waste in this
way pollutes the environment .
Landfills are found in the outskirts of the city .
Deep ditches are dug in the ground and the
garbage is dumped in them . When full these
ditches are covered with soil.
The household waste dumped in the pit , after
some time turns into Manure , which is called
as Compost . Crops grown using natural
manure instead of chemical fertilizers are
healthier . They are called Organic foods.
We should care for our environme-
nt and protect it in every way .
The waste we produce can be biod-
egradable or non-biodegradable.
