摘要：

The aim of the Green Brewery Concept is to demonstrate the potential for reducing thermal energy consumption in breweries, to substantially lower fossil CO(2) emissions and to develop an expert tool in order to provide a strategic approach to reach this reduction. Within the project "Green Brewery" three detailed case studies have been performed and a Green Brewery Concept has been developed. The project outcomes show that it is preferable to develop a tool instead of a simple guideline where a pathway to a CO(2) neutral thermal energy supply is shown for different circumstances. The methodology of the Green Brewery Concept includes detailed energy balancing, calculation of minimal thermal energy demand, process optimization, heat integration and finally the integration of renewable energy based on exergetic considerations. For the studied breweries, one brewery with optimized heat recovery can potentially supply its thermal energy demand over own resources (excluding space heating). The energy produced from biogas from biogenic residues of breweries and waste water exceeds the remaining thermal process energy demand of 37 MJ/hl produced beer. (C) 2011 Elsevier Ltd.
