Addition of animal manure and greenery will certainly enhance the performance of the activator.




(Picture: WaterAid in Ethiopia)Neighbourhoods can join with each other to share a digester. If enough wastes are produced, individual households can each have one and obtain the advantage of biogas manufacturing. You ought to check out if local loaning business could help families install an anaerobic biogas reactor.
