Composting is a simple process for transforming organic waste such as yard wastes, paper items, and kitchen scraps into decomposed organic soil called humus. Humus is nothing but a dark, black soil that is enriched with necessary nutrients, improves structures, holds the moisture content, and improves soil as a better environment for soil organisms. Normally, composting is done outdoors, but this process can also be carried out indoors also, and this is quite similar to outdoor composting. Indoor composting is becoming more popular because most of the population is getting attracted to a greener lifestyle.

Methods that are followed in indoor composting are aerobic composting, anaerobic composting and vermicomposting where air and moisture is very important in all methods. Air is very much required in aerobic composting whereas anaerobic composting does not require plenty of air. Due to less air supply, anaerobic method creates rotten smell, and today there are numerous products are available that reduces the bad smell. Another method vermicomposting is also called worm composting that uses earthworms to decompose organic substances, and best earthworm to use is red worms.

By properly feeding red worm, the worm can be made to work well to convert all the organic wastes in to black soil enriched with nutrients. Red worms, also called manure worms are commonly got from aged manure piles and from fish bait and these worms live happily in the room temperature. For indoor composting, a container or worm bin is required and the chosen container should fit conveniently under the cupboard or sink. The worm bin or container can be easily prepared with a wooden box and the wooden box should be at least 12 inches deep with small openings in the side and top for air movement and at the bottom of the box for drainage.

A tray needs to be put under the container to collect all seepage and it is good to place container on bricks to improve air circulation. In the container, simple damp bedding should be made to make this as a better environment for red worms. Then, kitchen wastes should be collected to feed the worm, and after six months the bedding gets changed in to rich black soil. Then, the rich black soil can be taken out through one side and from the other side new bedding can be inserted. Indoor compositing is a clean and odorless method to cut down trash and produce organic soil.
