Addition of pet manure and vegetation will boost the effectiveness of the activator.




(Picture: WaterAid in Ethiopia)Areas can join together to share a digester. However, if sufficient wastes are created, specific households can each have one and obtain the advantage of biogas production. You must check out if local loaning ventures might aid homes install an anaerobic biogas activator.
