Application of Cleaner Production Audit in Energy Conservation and Emission Reduction in the Beer Brewing Industry

The brewing industry is typically high pollution and energy consumption industry, the pollutant makes huge impact to the environment. It is necessary to reduce the energy consumption and emissions in the brewing industry. In this paper, based on the cleaner production (CP) audit of a beer brewing enterprise in Dalian, both the sources of the main pollutant and the reason of high energy consumption was analyzed. 3 medium/high CP projects and 4 none/low CP projects were carried out through technology and management improvement. By cleaner production audit, water consumption and sewage emissions can be reduced by 375 thousand tons and 350 thousand tons per year. Beer loss reduction ratio was 0.1%,energy can be totally saved by 3325 tons per year. The aims of energy conservation, energy and emissions reduction can be absolutely accomplished.
