A composting toilet, which can be either a centralized unit, (tank is away from the toilet,) or self contained, (tank is part of the toilet,) is a system wherein waste is broken down by bacteria and fungi to a soil, known as "humus." The main function of a composting toilet is to provide containment for the waste while it degrades, greatly diminishing any chance of human infection.
This type of toilet uses minimal water or no water at all. It treats the waste instantly so it can become a part of soil or useful compost that can be used as a fertilizer. It is beneficial to the user because the owner will only use less amount of water, thus reducing water usage and costs. The entire ecosystem will smile happily because using composting toilets reduce water contamination and will eventually lead to elimination of sewage systems that causes soil erosion and land pollution.
The composting toilet has been around for several decades now. In 1960’s Scandinavia created a toilet composting system and later on adopted by North America. Eventually, Canada and Australia followed, designing more advanced models of composting toilets.
