Toilets are an opportunity to reclaim plant nutrients from food which has been partially "processed" by humans. At present though, they are more often used to create water pollution or to contaminate the environment and spread disease.
- Pit toilets and latrines: both basically have a container holding the feces (not a septic tank as this allows microbial processing)
- Flush toilets (connected to the sewage collection system
- Flush toilets (connected to a septic tank)
- Composting toilets
- Drying toilets: these simply dry the feces, and have no composting process going on. In dry climates, note that desiccating or drying toilets may sometimes be more appropriate than composting toilets because the dry ambient air can be encouraged to flow through the faeces chamber removing any moisture, thus rendering the faeces dry and odourless. Some of these toilets are called "UDD (urine diversion-dehydrating) toilets". These dehydrate the urine, often trough the use of a faeces chamber or black ventilation pipe that has been painted black and left exposed to the sun.
