How can you become primary energy independent? The way to a self-sufficient brewery is presented by means of a medium-sized brewery. The project is based on a convincing energy concept, which won a regional award in Bavaria, Germany, and on funds granted by the German Federal Environment Agency (30% of 3.6 million Euros) due the project’s high potential. The restructuring of the entire brewery is presented in three steps: 1) new machines and plant engineering, 2) optimization of peripheral equipment, and 3) cross-linking of the implemented machines and engineering parts. New machines include all brewhouse equipment as well as a microturbine, a new heating vessel, an absorption cooling machine, and a pilot plant called Ice Age, producing snow for cooling purposes. In addition, different process changes are shown. The implementation of this concept leads to a reduction of approximately 280 tons of CO2 and 1.4 million kWh of natural gas saved annually.

Tobias Becher graduated as diploma engineer of brewing science and beverage technology in 2001 at the Technical University of Munich in Freising-Weihenstephan, Germany. He made an apprenticeship as brewer and maltster before and worked afterwards as process engineer for beer filtration systems. Later he worked as technical consultant especially for environmental issues in the German brewing sector. Since 2005 he has been employed by Ziemann, supplier of brewery equipment, as an expert for process engineering and brewing technology. Today he is head of research and development within the Process Technology Division at Ziemann Holvrieka GmbH in Ludwigsburg, Germany.
