Reclaim Waste Fundamentals Explained

An anaerobic biogas activator, also known as an anaerobic digester, uses anaerobic food digestion to transform liquid wastes and other organic matter into sludge and biogas. The sludge can be used as a soil fertiliser and the biogas can be made use of for power to produce warmth (for usage in cooking) or electricity.


The activator includes a chamber normally below the ground. It has an inlet for inputs (mostly human excreta) and 2 electrical outlets (one at the centre for biogas, and the other on one of the sides for electrical outlet of sludge). Enhancement of animal manure and greenery will boost the performance of the reactor.




If sufficient wastes are produced, private families can each have one and obtain the advantage of biogas manufacturing. In larger towns and cities, liquid waste might be communicated by means of a sewage network to a centralised wastewater therapy plant; for example, Addis Ababa's waste is treated at the Kality Wastewater Treatment Center.
