Addition of pet manure and greenery will improve the effectiveness of the reactor.




If sufficient wastes are generated, private families can each have one and obtain the advantage of biogas production. In larger communities and cities, fluid waste may be communicated via a sewage network to a centralised wastewater treatment plant; for example, Addis Ababa's waste is dealt with at the Kality Wastewater Therapy Facility.
