Clivus Multrum is a type of composting toilet and the name of a company that markets this brand name of composting toilets. "Clivus" is Latin for incline or slope; "multrum" is a Swedish composite word meaning "compost room", thus a "Clivus Multrum" is an inclined compost room. [1]

The first prototype was built in 1939 in Tyresö, Sweden, by art teacher Rikard Lindström, who owned a property on the Baltic Sea in Stockholm, Sweden. Lindström built a single-chamber concrete tank, with sloped bottom and chimney, for disposal of kitchen and toilet waste. It functioned for several decades and was eventually patented in 1962. In 1964, the first commercial model was constructed out of fiberglass.

In the 1970s, Abby Rockefeller, in the United States, read about the idea and wanted to buy a system, but was told they were not for sale due to lack of technical support. In 1973, Rockefeller founded Clivus Multrum, Inc. in Massachusetts under license from Lindström to market its composting toilet. The Clivus Multrum brand of composting toilets is marketed globally. [2]

Clivus Multrum today has designed a number of different prototypes and sizes. The process is advertised as enclosed, long-term composting and is characterized as being odor-free, low maintenance, and able to yield a clean, pathogen-free fertilizer that can be used in agriculture.[ citation needed ]

Outhouse Small structure, separate from a main building, which covers a toilet

An outhouse is a small structure, separate from a main building, which covers a toilet. This is typically either a pit latrine or a bucket toilet, but other forms of dry (non-flushing) toilets may be encountered. The term may also be used to denote the toilet itself, not just the structure.

Portable toilet Toilet that is easily moved around

A portable or mobile toilet is any type of toilet that can be moved around, some by one person, some by mechanical equipment such as a truck and crane. Most types do not require any pre-existing services or infrastructure, such as sewerage, but are completely self-contained. The portable toilet is used in a variety of situations, for example in urban slums of developing countries, at festivals, for camping, on boats, on construction sites, film locations, and large outdoor gatherings where there are no other facilities. Most portable toilets are unisex single units with privacy ensured by a simple lock on the door. Some portable toilets are small molded plastic or fiberglass portable rooms with a lockable door and a receptacle to catch the human excreta in a container.

Composting toilet Type of toilet that treats human excreta by a biological process called composting

A composting toilet is a type of dry toilet that treats human waste by a biological process called composting. This process leads to the decomposition of organic matter and turns human waste into compost-like material. Composting is carried out by microorganisms under controlled aerobic conditions. Most composting toilets use no water for flushing and are therefore called "dry toilets".

Laurance S. Rockefeller Preserve

The Laurance S. Rockefeller (LSR) Preserve is a 1,106 acres (448 ha) refuge within Grand Teton National Park on the southern end of Phelps Lake, Wyoming. The site was originally known as the JY Ranch, a dude ranch. Starting in 1927, John D. Rockefeller, Jr. purchased much of the land in Jackson Hole for the creation of Jackson Hole National Monument and the expansion of Grand Teton National Park. But he retained the 3,100-acre (1,300 ha) JY Ranch as a family retreat. Over the years the family gave most of the ranch to the national park. Laurance S. Rockefeller donated the final parcel in 2001. The donation came with special preservation and maintenance restrictions, with the vision that the preserve remain a place where visitors can experience a spiritual and emotional connection to the beauty of the lake and the Teton Range.

Urine diversion Separate collection of human urine and feces at the point of their production

Urine diversion, also called urine separation or source separation, refers to the separate collection of human urine and feces at the point of their production, i.e. at the toilet or urinal. Separation of urine from feces allows human waste to be treated separately and used as a potential resource. Applications are typically found where connection to a sewer-based sanitation system is not available or areas where water supplies are limited.

Dry toilet Toilet that operates without flush water

A dry toilet is a toilet which, unlike a flush toilet, does not use flush water. Dry toilets do not use water to move excreta along or block odors. They do not produce sewage, and are not connected to a sewer system or septic tank. Instead, excreta falls through a drop hole.

C. K. Choi Building University Office Building in Vancouver, Canada

The C. K. Choi Building is a building known for its sustainable design features. It is the University of British Columbia's "flagship environmental building" in what it calls its 'living laboratory', the campus used to showcase "innovative approaches to conserving energy, water and materials, while striving to make positive impacts on the environment." Located in the northwest quadrant of the UBC campus, the building is named after Dr. Cheung-Kok Choi, a businessman and philanthropist in China, Hong Kong and Canada, and a major donor to UBC. The C.K. Choi Building was purpose-built as a university office building to house UBC's Institute of Asian Research's five research centres. These focus on China, Japan, Korea, Southeast Asia, and India and South Asia. The "daringly innovative architecture" integrates cultural expression, interior and exterior architectural presence, together with environmental features and functions. The five identical curved roof forms reflect the institute's Asian focus, providing an identifiable focus for each research centre without giving predominance to one culture or centre over another, and provide natural light and natural ventilation to interior spaces.

A multrum is a large composting vessel, predominantly meant to decompose toilet excreta but also other organic residue. It is originally a composite word consisting of "multna" which means moldering or composting in Swedish and "rum" which is the Swedish word for room. A multrum has over several decades become a noun and has come to mean any large composting chamber connected to a toilet. This should not be confused with Clivus multrum which is a proprietary product. In Scandinavia there are many kinds of composting toilet multrums like Mullis, CompostEra besides Clivus Multrum.

Urine-diverting dry toilet Dry toilet with separate collection of feces and urine without any flush water

A urine-diverting dry toilet (UDDT) is a type of dry toilet with urine diversion that can be used to provide safe, affordable sanitation in a variety of contexts worldwide. The separate collection of feces and urine without any flush water has many advantages, such as odor-free operation and pathogen reduction by drying. While dried feces and urine harvested from UDDTs can be and routinely are used in agriculture, many UDDTs installations do not apply any sort of recovery scheme. The UDDT is an example of a technology that can be used to achieve a sustainable sanitation system. This dry excreta management system is an alternative to pit latrines and flush toilets, especially where water is scarce, a connection to a sewer system and centralized wastewater treatment plant is not feasible or desired, fertilizer and soil conditioner are needed for agriculture, or groundwater pollution should be minimized.

Reuse of human excreta Safe, beneficial use of human excreta mainly in agriculture (after treatment)

Reuse of human excreta is the safe, beneficial use of treated human excreta after applying suitable treatment steps and risk management approaches that are customized for the intended reuse application. Beneficial uses of the treated excreta may focus on using the plant-available nutrients that are contained in the treated excreta. They may also make use of the organic matter and energy contained in the excreta. To a lesser extent, reuse of the excreta's water content might also take place, although this is better known as water reclamation from municipal wastewater. The intended reuse applications for the nutrient content may include: soil conditioner or fertilizer in agriculture or horticultural activities. Other reuse applications, which focus more on the organic matter content of the excreta, include use as a fuel source or as an energy source in the form of biogas.

Container-based sanitation Sanitation system which uses mobile containers

Container-based sanitation refers to a sanitation system where toilets collect human excreta in sealable, removable containers that are transported to treatment facilities. This type of sanitation involves a commercial service which provides certain types of portable toilets, and delivers empty containers when picking up full ones. The service transports and safely disposes of or reuses collected excreta. The cost of collection of excreta is usually borne by the users. With suitable development, support and functioning partnerships, CBS can be used to provide low-income urban populations with safe collection, transport and treatment of excrement at a lower cost than installing and maintaining sewers. In most cases, CBS is based on the use of urine-diverting dry toilets.
