The reactor includes a chamber typically listed below the ground. It has an inlet for inputs (mainly human excreta) and two electrical outlets (one at the centre for biogas, and the various other on among the sides for electrical outlet of sludge). Enhancement of pet manure and plants will certainly improve the efficiency of the reactor.




If adequate wastes are produced, individual households can each have one and obtain the benefit of biogas production. In bigger towns and cities, fluid waste might be communicated via a sewerage network to a centralised wastewater therapy plant; for example, Addis Ababa's waste is dealt with at the Kality Wastewater Treatment Center.
