	'''Human waste''' (or '''human excreta''') refers to the waste products of the [[human digestive system]], [[menses]], and human [[metabolism]] including [[urine]] and [[Human feces\|~~faeces~~]]. As part of a [[sanitation]] system that is in place, human waste is collected, transported, treated and disposed of or reused by one method or another, depending on the type of [[toilets\|toilet]] being used, ability by the users to pay for services and other factors.

	Human waste is considered a [[Biomedical waste\|biowaste]], as it is a [[Vector (epidemiology)\|vector]] for both [[Virus disease\|viral]] and [[Pathogenic bacteria\|bacterial]] diseases. It can be a serious health hazard if it gets into sources of drinking water. The [[World Health Organization]] (WHO) reports that nearly 2.2 million people die annually from diseases caused by contaminated water, such as cholera or ~~diarrhea~~. A major accomplishment of human civilization has been the reduction of [[Transmission_(medicine)\|disease transmission]] via human waste through the practice of [[hygiene]] and [[sanitation]], which can employ a variety of different technologies.

'''Human waste''' (or '''human excreta''') refers to the waste products of the [[human digestive system]], [[menses]], and human [[metabolism]] including [[urine]] and [[Human feces|faeces]]. As part of a [[sanitation]] system that is in place, human waste is collected, transported, treated and disposed of or reused by one method or another, depending on the type of [[toilets|toilet]] being used, ability by the users to pay for services and other factors.

People in [[Developed country|developed countries]] tend to use [[Flush toilet|flush toilets]] where the human waste is mixed with water and transported to [[sewage treatment plants]].

Children's excreta can be disposed of in [[diaper]]s and mixed with [[municipal solid waste]]. Diapers are also sometimes dumped directly into the environment, leading to [[public health]] risks.

==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 toilet|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 [[urinal (restroom)|urinal]]s and [[composting toilet]]s 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 [[Bucket toilet|honey bucket]]s and sewage lagoons (see [[anaerobic lagoon]]) without the threat of disease presented by places with denser populations. [[Bucket toilet|Bucket toilets]] are used by rural villages in [[Alaska]] where, due to [[permafrost]], conventional waste treatment systems cannot be utilized.

==Uses==
{{Main|Reuse of excreta}}
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.<ref>''[https://archive.today/20130129114955/http://news.nationalgeographic.com/news/2008/08/080821-human-waste.html Human Waste Used by 200 Million Farmers, Study Says]'', National Geographic News, August 21, 2008</ref>
