Biogas Technology For Rural Development In Zimbabwe

This paper reports laboratory experiments of the anaerobic digestion of pigeon droppings and waste material from coffee processing and the application of these findings in field trials using three types of biogas digesters designed and built in Zimbabwe. It is concluded that biogas technology may be a feasible solution to the shortage of wood-fuel and fertiliser in the rural areas.
