Generating biogas from spent grains – 47% savings in energy costs
The production of biogas from organic wastes originating during beer production offers an economically viable and environmentally sustainable alternative to existing recycling solutions. Using the biogas technology “ENBAFERM” patented by the Austrian company enbasys®, it is possible to integrate biogas production into an existing brewery, thus guaranteeing optimized energy production on-site. Since 2009, a demonstration system incorporating this technology has been in operation at the Bavarian State Brewery Weihenstephan in Freising, Germany. This system has been successfully used to ferment spent yeast and spent grain waste.
