Steps of usage of the<unk> .<unk>  in Ekwendeni, Malawi An<unk>  is a simple type of composting toilet in which feces are collected in a shallow pit and a fruit tree is later planted in the fertile soil of the full pit.<unk> s have: a pit like a pit latrine but less deep; a concrete, ferrocement or other strong floor; a superstructure (toilet house or outhouse) to provide privacy; and possibly a ring beam to protect the pit from collapsing. The pit should remain well above the water table in the soil, so as to not contaminate groundwater. The<unk>  works by temporarily putting the slab and superstructure above a shallow pit while it fills. Feces, urine, paper, leaves, other materials for wiping, and potentially anal wash water all go into the pit. After each use, a cup of the excavated soil should be added to help to control smell and flies. When the pit is nearly full, the outhouse and slab are moved to a newly dug pit and the old pit is covered with some of the earth from the new pit and left to compost. A fruit tree or other useful vegetation is planted in the old pit, preferably during the rainy season. Feces are safely stored and converted in the soil, avoiding disease transmission, and do not have to be processed or manipulated by anyone. Instead, fruits on trees are grown, fertilised by human excreta. The<unk>  is a type of dry toilet. By using the nutrient-rich soil of a retired pit, the<unk> , in effect, treats feces as a resource rather than a waste product.<unk> s are used in rural areas of many developing countries, for example in Zimbabwe, Malawi and Ethiopia.
