ToiletA toilet is a piece of sanitary hardware that collects human urine and feces, and sometimes toilet paper, usually for disposal. Flush toilets use water, while dry or non-flush toilets do not. They can be designed for a sitting position popular in Europe and North America with a toilet seat, with additional considerations for those with disabilities, or for a squatting posture more popular in Asia, known as a squat toilet. In urban areas, flush toilets are usually connected to a sewer system; in isolated areas, to a septic tank.
Municipal solid wasteMunicipal solid waste (MSW), commonly known as trash or garbage in the United States and rubbish in Britain, is a waste type consisting of everyday items that are discarded by the public. "Garbage" can also refer specifically to food waste, as in a garbage disposal; the two are sometimes collected separately. In the European Union, the semantic definition is 'mixed municipal waste,' given waste code 20 03 01 in the European Waste Catalog.
Community-led total sanitationCommunity-led total sanitation (CLTS) is an approach used mainly in developing countries to improve sanitation and hygiene practices in a community. The approach tries to achieve behavior change in mainly rural people by a process of "triggering", leading to spontaneous and long-term abandonment of open defecation practices. It focuses on spontaneous and long-lasting behavior change of an entire community. The term "triggering" is central to the CLTS process: It refers to ways of igniting community interest in ending open defecation, usually by building simple toilets, such as pit latrines.
Waste-to-energyWaste-to-energy (WtE) or energy-from-waste (EfW) is the process of generating energy in the form of electricity and/or heat from the primary treatment of waste, or the processing of waste into a fuel source. WtE is a form of energy recovery. Most WtE processes generate electricity and/or heat directly through combustion, or produce a combustible fuel commodity, such as methane, methanol, ethanol or synthetic fuels. The first incinerator or "Destructor" was built in Nottingham, UK, in 1874 by Manlove, Alliott & Co.
Human fecesHuman feces (or faeces in British English) is the solid or semisolid remains of food that could not be digested or absorbed in the small intestine of humans, but has been further broken down by bacteria in the large intestine. It also contains bacteria and a relatively small amount of metabolic waste products such as bacterially altered bilirubin, and the dead epithelial cells from the lining of the gut. It is discharged through the anus during a process called defecation.
Zero wasteZero waste is a set of principles focused on waste prevention that encourages redesigning resource life cycles so that all products are repurposed (i.e. “up-cycled”) and/or reused. The goal of the movement is to avoid sending trash to landfills, incinerators, oceans, or any other part of the environment. Currently 9% of global plastic is recycled. In a zero waste system, all materials are reused until the optimum level of consumption is reached. Zero waste refers to waste prevention as opposed to end-of-pipe waste management.
Waste managementWaste management or waste disposal includes the processes and actions required to manage waste from its inception to its final disposal. This includes the collection, transport, treatment, and disposal of waste, together with monitoring and regulation of the waste management process and waste-related laws, technologies, and economic mechanisms. Waste can be solid, liquid, or gases and each type has different methods of disposal and management.
Urine collection deviceA urine collection device or UCD is a device that allows the collection of urine for analysis (as in medical or forensic urinalysis) or for purposes of simple elimination (as in vehicles engaged in long voyages and not equipped with toilets, particularly aircraft and spacecraft). UCDs of the latter type are sometimes called piddle packs. Similar devices are used, primarily by men, to manage urinary incontinence. These devices attached to the outside of the penile area and direct urine into a separate collection chamber such as a leg or bedside bag.
Toilets in JapanToilets in Japan are sometimes designed more elaborately than toilets commonly seen in other developed nations. European toilets occasionally have a separate bidet whilst Japan combines an electronic bidet with the toilet. The current state of the art for Western-style toilets in Japan is the bidet toilet, which is installed in 81% of Japanese households. In Japan, these bidets are commonly called washlets, a brand name of Toto Ltd., and they may include many advanced features rarely seen outside of Asia.
Pit latrineA pit latrine, also known as pit toilet, is a type of toilet that collects human waste in a hole in the ground. Urine and feces enter the pit through a drop hole in the floor, which might be connected to a toilet seat or squatting pan for user comfort. Pit latrines can be built to function without water (dry toilet) or they can have a water seal (pour-flush pit latrine). When properly built and maintained, pit latrines can decrease the spread of disease by reducing the amount of human feces in the environment from open defecation.
