Toelichting (Engels) In 2015, the Austrian company BDI set up an anaerobic digestion unit at the site of one of the biggest breweries in Austria, the Gösser Brewery close to Leoben (figure 1). This facility has a yearly production of approximately 100 Million litres of beer. The Gösser Brewery, which is part of the Heineken Group, decided to establish a decarbonised beer production facility as their contribution to greening of the brewing industry. During the brewing process several organic residues are generated, which can be used as feedstock for an anaerobic digestion process. Each hectolitre of beer (100 litres) produces approximately 20 kg of brewers’ spent grains. Furthermore, residual yeast, hot and cold break (a protein rich fraction from the brewing process), filter cake and waste water are residues which occur during the brewing process. Anaerobic treatment of waste water is currently realised on-site for most breweries. Different technologies are employed including for Upflow Anaerobic Sludge Blanket (UASB) and Expanded Granular Sludge Blanket (EGSB).
