Composting is the process wherein you can convert organic waste into useful manure by aerobic conversion. The active organism in conventional vermicomposting are earthworms. It is a fairly easy process which is very beneficial in reducing the amount of our waste by turning it into something useful and natural. Anybody with a spare piece of land and some training can effectively produce manure and contribute to saving the environment. The detailed process is as follows-
1. You need a lot of organic or wet waste. Organic waste is your regular kitchen waste like peels of fruits and vegetables, uncooked and cooked items, teabags, dead leaves, plant and animal products, refuse, excreta etc. The main characteristics of this type of waste is that it decomposes very fast and produces stink. In hot climates, it decomposes at a faster rate than colder climates. This waste should not be burned often as it produces methane gas which adds to the Green House Gases (GHG) or climate change.
2. This waste is transported (or ideally should be transported) to the composting site by your local waste picker and/or waste management service provider.
3. Sometimes the waste is mixed with wastes, which could be recycled (like glass, plastic, paper etc), and should be segregated before being put for composting. It is always beneficial to do segregation at source, i.e. homes, in order to save time, effort and costs.
4. Special composting pits are prepared in the shape of rectangular boxes as shown. A composting site can have a number of such pits.
5. The waste is mixed with cowdung in the pits. A special type of worms are used which are derived from Australia and are usually reddish in color. A typical worm egg gives about 5-6 worms. They are different from the common earthworms found locally as they don't eat the soil and only break-down the waste into smaller units.
7. When it is done, the compost is taken out from the top as the worms seep at the bottom. The compost is then sieved to remove extra worms. It is now ready to be packed and sold off or to be used in your garden.

6. It takes about a month for the waste to fully convert into rich manure. In the time being, it is suggested that the waste be turned around with a shovel to improve air supply. The worms prefer a darker environment to work in, so the pit is covered with dead leaves to reduce direct sunlight.
