During the last years breweries traditional disposal possibilities of brewer’s spent grain (BSG) face a remarkable change like the decline in the demand as animal feed. Due to its high organic content an energetic utilization can create an additional benefit for breweries. Furthermore, breweries tend to shift their energy supply more and more towards sustainable energy concepts. Although, a decent number of research projects were carried out already, still no mature strategy is available. Using a mechanical pre-treatment allows optimized energy utilization by fractionation BSG and could solve the problem.
