Sanitation

sanitaryunsanitarypublic sanitation
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 toilet being used, ability by the users to pay for services and other factors. Improvements in "water, sanitation and hygiene" (WASH) around the world is a key public health issue within international development and is the focus of Sustainable Development Goal 6.
Sanitation refers to public health conditions related to clean drinking water and adequate treatment and disposal of human excreta and sewage.

Human feces

stoolfecesstools
Human waste (or human excreta) refers to the waste products of the human digestive system and the human metabolism, namely feces and urine. The term "human waste" is used in the general media to mean several things, such as sewage, sewage sludge, blackwater - in fact anything that may contain some human feces.
Human feces together with human urine are collectively referred to as human waste or human excreta.

Fecal sludge management

fecal sludgeseptagefaecal sludge
Fecal sludge management is used to deal with fecal matter collected in on-site sanitation systems such as pit latrines and septic tanks.
Fecal sludge is a mixture of human excreta, water and solid wastes (e.g. toilet paper or other anal cleansing materials, menstrual hygiene materials) that are disposed of in pits, tanks or vaults of onsite sanitation systems.

Urine

Human waste (or human excreta) refers to the waste products of the human digestive system and the human metabolism, namely feces and urine.
Human urine and feces are collectively referred to as human waste or human excreta, and are managed with a sanitation system.

Toilet

Chemical toilets collect human excreta in a holding tank and use chemicals to minimize odors.

Flush toilet

water closetflushing toiletWC
People in developed countries tend to use flush toilets where the human waste is mixed with water and transported to sewage treatment plants.
A flush toilet (also known as a flushing toilet, water closet (WC) – see also Toilet (names)) is a toilet that disposes of human excreta (urine and feces) by using water to flush it through a drainpipe to another location for disposal, thus maintaining a separation between humans and their excreta.

Human digestive system

digestive systemdigestivedigestive tract
Human waste (or human excreta) refers to the waste products of the human digestive system and the human metabolism, namely feces and urine.
The remaining semi-solid waste is termed feces and is removed by the coordinated contractions of the intestinal walls, termed peristalsis, which propels the excreta forward to reach the rectum and exit via defecation from the anus.

Sewage

raw sewagedomestic sewagedrainage system
The term "human waste" is used in the general media to mean several things, such as sewage, sewage sludge, blackwater - in fact anything that may contain some human feces.
It consists mostly of greywater (from sinks, tubs, showers, dishwashers, and clothes washers), blackwater (the water used to flush toilets, combined with the human waste that it flushes away); soaps and detergents; and toilet paper (less so in regions where bidets are widely used instead of paper).

Water supply

Improvements in "water, sanitation and hygiene" (WASH) around the world is a key public health issue within international development and is the focus of Sustainable Development Goal 6.
Water supply can get contaminated by pathogens which may originate from human excreta, for example due to a break-down or design fault in the sanitation system, or by chemical contaminants.

Composting toilet

A composting toilet is a type of dry toilet that treats human excreta by a biological process called composting.

Bucket toilet

honey bucketBucket latrinesbucket toilets or pan latrines
A bucket toilet is a basic form of a dry toilet whereby a bucket (pail) is used to collect excreta.

Dry toilet

For example, dry toilets collect human waste without the addition of water.

Greywater

Greywater usually contains some traces of excreta and is therefore not free of pathogens.

Biomedical waste

Human waste is considered a biowaste, as it is a vector for both viral and bacterial diseases.

Compost

Human waste can be added as an input to the composting process since human excreta is a nitrogen-rich organic material.

The sanitation systems in place differ vastly across the world, with many people in developing countries having to resort to open defecation where human waste is deposited in the environment, for lack of other options.
