Disposal of
solid waste
There are various ways of disposing
safely and wisely. Some ways are following:
Open
Dumping: Open Dumping means throwing the wastes in the open area which is
outside the city or town, where the movement of people is less. This waste
keeps decaying over a period of time.
Disposal of wastes in this method is
not good, because it pollutes the air by breeding more and more germs. It gives
a foul smell and makes our surrounding air dirty.
Composting:
Composting is a natural way of making waste useful. When fruits and vegetable peels,
dead leaves and cow dung are dumped in a pit and covered, then microbes work on
them and help to rot them. They mix them with the soil and form compost or
manure. This is called Composting.
Bio gas:
Bio gas is made from peels, seeds, pulp and other
Biodegradable wastes. When
these wastes are filled in tanks and
covered, then it is treated in a special
way to make a clean and non-
smelling gas called bio gas. This gas is safe and
used for cooking
and other domestic uses.
Sanitary
Land Filling: Sanitary land filling means throwing the waste in a deep pit.
When this pit is full, it is closed with a thick layer of soil. Water is poured
over it. After sometime all the wastes materials get composed and become a good
manner.
It is a good way of disposal, because
it does not pollute the air. In village, similar practice is adapted by making
compost pits.
Incineration:
Incineration means burning the waste materials in open space. First, all the
waste materials are dumped and allowed to dry. When they are dried, they are
burnt. This does not allow germs to grow but causes air pollution.
