human urine recycling

Urine-separating toilets, known as ecosan toilets, are already available in Bahir Dar, such as here at Qulkual Meda elementary school. However, the urine in these toilets is not always separated in the way it should be, and if it is, it is not collected. When the containers become full, they overflow. Photo: Eshetu Assefa
