Editing Composting toilet (section)

=== Construction ===
The composting chamber can be constructed above or below ground level. It can be inside a structure or include a separate superstructure.

A drainage system removes [[leachate]]. Otherwise, excess moisture can cause anaerobic conditions and impede decomposition. Urine diversion can improve [[compost]] quality, since urine contains large amounts of [[ammonia]] that inhibits microbiological activity.<ref name=":0">{{Cite web|url = http://ecompendium.sswm.info/sanitation-technologies/composting-chamber?group_code=s|title = The online Compendium of Sanitation Systems and Technologies|date = 2014|access-date = 2014-12-29|website = The online Compendium of Sanitation Systems and Technologies|publisher = eawag aquatic research}}</ref>

Composting toilets greatly reduce human waste volumes through [[Psychrophile|psychrophilic]], [[Thermophile|thermophilic]] or [[Mesophile|mesophilic]] composting. Keeping the composting chamber insulated and warm protects the composting process from slowing due to low temperatures.
