This paper describes a biogas production scheme for urban and agricultural organic wastes. These are collected separately and fermented anaerobically in an underground steel storage vessel, producing biogas. The biogas is collected on top in a gasometer chamber and is processed to meet the required fuel standards. The heavy non-fermentable components sink to the bottom and are pumped up out of the main storage vessel to their final destination. The local water table is protected by separating the underground storage vessel from the ground by an air space for easy inspection and maintenance. Most of the plant is underground: an advantage in urban areas. A detailed technical and economic feasibility study is proposed.
