Composting

Composting is a biochemical process in which organic materials such as lawn clippings and kitchen scraps decompose to a rich, soil-like material. It is a process of rapid, partial decomposition of moist, solid, organic waste by aerobic organisms. As a waste management option large-scale composting is generally carried out in the controlled environment of mechanical digesters.  A major disadvantage of composting is the necessity to separate organic material from other waste. Therefore, it is probably economically advantageous only when organic material is collected separately from other waste.  Nevertheless, composting is an important component of IWM and can be used as an organic soil fertilizer, topsoil, or landfill cover.
