Schematic of the<unk>  chamber which is located below the toilet seat The term<unk> " is used quite loosely, and its meaning varies by country. For example, in Germany and Scandinavian countries,<unk>  always refers to a predominantly aerobic process. This aerobic<unk>  may take place with an increase in temperature due to microbial action, or without a temperature increase in the case of slow<unk>  or cold<unk> . If earth worms are used (vermicomposting) then there is also no increase in temperature.<unk> s differ from pit latrines and arborloos, which use less controlled decomposition and may not protect groundwater from nutrient or pathogen contamination or provide optimal nutrient recycling. They also differ from urine-diverting dry toilets (UDDTs) where pathogen reduction is achieved through dehydration (also known by the more precise term "desiccation") and where the feces collection vault is kept as dry as possible.<unk> s aim to have a certain degree of moisture in the<unk>  chamber.<unk> s can be used to implement an ecological sanitation approach for resource recovery, and some people call their<unk>  designs "ecosan toilets" for that reason. However, this is not recommended as the two terms (i.e.<unk>  and ecosan) are not identical. Schematic of a<unk>  with urine diversion<unk> s have also been called "sawdust toilets", which can be appropriate if the amount of aerobic<unk>  taking place in the toilet's container is very limited. The "Clivus multrum" is a type of<unk>  which has a large<unk>  chamber below the toilet seat and also receives undigested organic material to increase the carbon to nitrogen ratio. Alternatives with smaller<unk>  chambers are called "self-contained<unk> s" since the<unk>  chamber is part of the toilet unit itself.
