Composting toilets

A composting toilet is a system which converts human waste into usable soil and and organic compost, through natural breakdown of the organic matter into its essential minerals. The micro and macro organisms work through a range of oxidation stages.

Composting toilets consist of a huge compartment beneath the toilet; this is called ‘Clivus Multrum’. Some use electricity and others electrical systems to increase microbial activities and to expel air. Other toilets require the use of a rotating drum or rotating tines inside the toilet to permit an aerobic waste breakdown. Some have self-contained systems while others have central units which are powered by a vacuum to flush the waste towards the remote composting system beneath the toilet. There are also some toilet composters which utilise heat and use air to speed up the rate of aerobic decomposition. Today’s best composting toilets are able to separate faeces from urine, hence, provide fertilisers in two varied types. After the breakdown process, the urine is responsible for providing nutrients into an unscented liquid fertiliser.

To decrease the foul smell, a composting toilet needs quick drying contents. To speed up this system process, special composting toilets were created. Basically, all composting toilets need end-product removal. This occurs as early as three months, while the solid waste takes four to six years before it becomes a mineralised soil, which is considered the best fertiliser on earth.

In Canada and Sweden, composting toilets are widely accepted. Generally, composting toilets are prohibited; nevertheless, this is widely challenged and numerous people use them to greenify the environment without anyone noticing it.
