Anaerobic digestion of manure, biomass or wastes may be considered as one of the most interesting processes as a source of renewable energy thus  reducing the emission of greenhouse gas in the atmosphere.

The high concentration of organic material is converted by means of bacterium in anaerobic conditions to biogas, which later can be used to power a cogeneration plant. A second benefit of the digestion process is that the solid product can be safely disposed, or re-used as fertilizer, so that it leads to net environmental benefit regarding a lot of impacts. The seminary offers a wide overview on the most employed technology, as well as on the culture or by-products that can be fed in an anaerobic digester.
