The sludge can be utilized as a soil fertilizer and the biogas can be utilized for power to generate warm (for usage in food preparation) or electrical power.


The activator is composed of a chamber generally below the ground. It has an inlet for inputs (mostly human excreta) and two electrical outlets (one at the centre for biogas, and see here now the other on among the sides for outlet of sludge). Enhancement of pet manure and vegetation will boost the effectiveness of the activator.




If enough wastes are produced, individual houses can each have one and obtain the advantage of biogas manufacturing.
