The present report concerns a biogas production scheme for urban and agricultural organic wastes. They are collected separately and stored in liquid water suspension in an underground steel vessel where biogas is continuously produced by anaerobic selected bacteria-enhanced fermentation. The biogas mixture is collected on top of a suitable gasometer chamber and is subjected to specific physico-chemical processes in order to achieve the standards required for any selected energetic application. The heavy non-fermentable components sink to the bottom in the form of an inert digested slush and are pumped up out of the main storage vessel to their final destination. Valuable fuel is recovered by adopting a rational organic waste disposal method.
