Dry composting toilets use bacteria to decompose feces into CO2 and a biological compost usable for plants. Using it directly for edible vegetable production is an open issue. However, a Martian settlement will require plenty of non comestible plantations, although green laws in front of housing is a long way into the future..

Products of combustion are mainly CO2 and some Volatile Organic Compounds (VOCs)s, plus some ash. The CO2 and the gases can be collected by vents are treated in an air cleaning system, with activated charcoal for the VOCs and adsorption for the CO2. The ash can be collected and used as fertilizer or to create soap.

			[[Waste water treatment]] is a well developed technology that is commonly used on Earth in local or regional type systems. Packages systems exist for locations ranging from a construction camp to a small village. Larger systems are usually build per specifications and entire cities can be handled by a single centralized system.

[[Human]] beings need a '''toilet'''. The removal of '''feces''' is a daily business. This page wants to collect possible methods that may be useful in a Martian [[colony]]. The concepts reach from [[hi-tech versus lo-tech|lo-tech to hi-tech]].

==Lo-tech concepts==

===Pit latrine===
A simple pit latrine in the [[greenhouse]] allows to mix the feces with [[soil]],[[compost]] and [[regolith]], which can be used to grow [[food]] plants. [[Terra preta]] can be made.

===Maggots===
Certain [[insects|insect larvae]] can live solely on feces. They produce valuable proteins.

==Hi-tech concepts==
Technical waste water recycling is used on the [[ISS]]. It filters some chemicals out and provides fresh water as a result. Urine contains high levels of [[nitrogen]] and [[phosphorus]] and can be used to make fertilizers.
