environment than uncontrolled deposit of urine, due to the higher pathogen content of faeces. Methods of processing Methods of processing depend on the type of human waste: Sewage is treated via sewage treatment Sewage sludge is treated by sewage sludge treatment Fecal matter from dry toilets may undergo composting Fecal sludge from pit latrines is treated and managed with an approach called fecal sludge management The amount of water mixed with human waste can be reduced by the use of waterless urinals and composting toilets and by recycling greywater. The most common method of human waste treatment in rural areas where municipal sewage systems are unavailable is the use of septic tank systems. In remote rural places without sewage or septic systems, small populations allow for the continued use of honey buckets and sewage lagoons (see anaerobic lagoon) without the threat of disease presented by places with denser populations. Bucket toilets are used by rural villages in Alaska where, due to permafrost, conventional waste treatment systems cannot be utilized. Uses Human waste in the form of wastewater (sewage) is used to irrigate and fertilize fields in many parts of the developing world where fresh water is unavailable. There is great potential for wastewater agriculture to produce more food for consumers in urban areas, as long as there is sufficient education about the dangers of eating such food uncooked.
