<p>The invention relates to an apparatus for the conversion into biogas of fermentation broth arising as a waste product of ethanol production. This apparatus comprises a separation unit for the separation of the fermentation broth into a thin fraction and a thick fraction, at least one biogas reactor for fermenting the thin fraction and/or the thick fraction, and a storage tank. A process is also described, using two biogas reactors for the anaerobic digestion of the thin fraction and the thick fraction independently of one another.</p> |
