M-73: Sustainability of beer filtration

J. P. ZUBER (1); (1) Bucher Filtrox Systems AG, St. Gallen, Switzerland


Sustainability is at the top of the agenda of all major brewery groups, including leading craft brewers. Companies like SABMiller have put a lot of effort into reducing the water and energy consumption of their breweries, and leading craft brewers like Sierra Nevada and New Belgium are frontrunners in this aspect. Although filtration has a minor impact on the overall carbon footprint of a brewery or a six-pack of beer (result of a study by New Belgium), it is a piece of the puzzle and, therefore, has to be considered. In spite of the bad image of DE and the promises of membrane producers, traditional precoat filtration has a substantially lower impact on the environment than membrane systems. This was confirmed by an independent study conducted by BASF.

Juerg Zuber completed his studies at the Federal Institute of Technology (ETH) in Zurich, Switzerland, in 1977 with a master’s degree in process engineering. He then joined Buhler AG, where he worked for more than 20 years in a variety of R&D and management positions. In 2000 he joined Filtrox AG, where he was responsible for the engineering business. He is currently managing director of Bucher Filtrox Systems AG, a leading producer of filtration systems for the beverage and food industries, which is part of the Swiss Bucher Industries. He is also responsible for the American market.
