Abstract: The present invention relates to a method and equipment for carrying out the degradation of various organic products or waste in an anaerobic medium. The equipment comprises a plurality of ducts for reinjecting biogas into a fermentation vat sidewise spaced from each other and disposed at least in the major part of the vat, the duct being fed with biogas individually or in groups through independent valves so as to subdivide the fermentation vat into sectors independently fed with biogas. Preferably, a container is provided for storing biogas under pressure. These features lead to a simplification of the equipment and a decrease in the manufacturing costs.
