The activator includes a chamber generally listed 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 among the sides for electrical outlet of sludge). Enhancement of pet manure and plant life will boost the effectiveness of the reactor.




If sufficient wastes are created, private homes can each have one and get the advantage of biogas manufacturing.
