SOLID WASTE may be of Two Types:
Substances which undergo Degradation Or Rots by the action of Decomposers and are broken down to harmless or non-poisonous substances.
E.g., Dead Plants and Animals, Paper, Cloth and many more.
NON- BIODEGRADABLE WASTE
Substances which cannot be broken down by Decomposers.They do not rot easily or take a very long time to ROT.
Large Open areas used for Solid Waste Disposal.
These areas are usually Low-lying Areas and are away from Residential Areas.
The garbage from the Dumps is taken to the Land fill area, spread and then covered with soil.
Once the land fill area is full, it is left as such for a long time … say about 20 yrs.
Finally the area can be converted into a Park or a Playground.
The conversion of solid waste into manure is called composting.
The manure produced by composting is called compost.
Composting is done inside pits dug in the soil.
The pits are called compost pits.
The method of preparing compost with the help of a special type of earth-worm called red-worm is called Vermi Composting.
Garbage used to make compost like Fruit or Vegetable Peels, tea leaves etc can be used for Vermi Composting.
These materials act as food for the red worms.
The worms convert these wastes into compost which is inexpensive and can be used in fields and gardens without causing pollution.
