Price wars in the beer sector are putting small and medium-sized rural breweries under pressure. So countryside brewers are happy about new ideas for reducing energy costs. A new method is currently being developed by the Munich University of Technology and the Frauenhofer UMSICHT in Sulzbach-Rosenberg in conjunction with the Weisses Bräuhaus brewery could be ground-breaking in the future. With the method, brewers’ grains – malt residue drained during the brewing process – could be used right at the brewery in a biomass heating plant for generating heat for the brewery. This would not only benefit the company, but also the environment and the climate.
