ABSTRACT:
A method and apparatus for carrying out a degradation in an anaerobic medium, such as a methanogenesis, of organic products, by-products or waste from human, animal and/or plant origin, involving feeding said products to be degraded into a closed fermentation vessel, forcing said products to flow in a direction of circulation within said vessel and recovering the gas produced called biogas evolved above said body of degraded products, with the feeding and/or discharge of the products performed pneumatically, preferably through pneumatic thrust and, according to a preferred embodiment, by injection of gas, preferably biogas. A further improvement comprises using the biogas produced for homogenizing said body of products contained within said vessel, the pressure of injection being in relation to the actual density of the products, in the injection related section.
