Ecological sanitation: A concept

Ecological sanitation (ecosan) works on the principle that human excrement is not a waste product but contains the nutrients required to fertilise land and that it should be used for this purpose. The ecological sanitation cycle begins with containment, where excreta is held in the sanitation installation. The waste is then sanitised through one or several processes which cause pathogen die off, the resultant safe soil conditioner (from faeces) and fertiliser (from urine) is then recycled and used to assist crop production.
