Normal 0 false false false EN-US ZH-CN X-NONE Brewing is the third largest sector of the EU food industry after Dairy and Meat Production. In the UK, increasing number of small-medium size brewery plants are still playing important role in this industry, which produce local brand beers welcomed in their regions. However, brewing is an energy-intensive process, which consumes large amount of electricity, heating and cooling energy, at the same time generate organic wastes and sludge waters. This study looks into the beer production process of a medium size brewery to analyze energy consumption in the process and investigate the feasibility of applying Anaerobic Digestion system to tackle with the organic wastes and produce biogas as well. The biogas is further used on site by a biogas fired CHP/Trigeneration system based on gas engine generator. The electrical/thermal energy derived from biogas could cover all the thermal demands in the brewing house and meet the cooling demands of fermentation and maturing (conditioning) process. In three scenarios, biogas fired CHP/Trigeneration shows an advantage on utility energy savings when compared with biogas boiler or biogas directly fired absorption chiller.
