The work aims to study the feasible green management strategy of beer fermentation tank to reduce the whole life cycle carbon emission of beer fermentation tank. Based on the analysis of the raw material collection stage, manufacturing stage, transportation stage, use stage and recovery stage of beer fermentation tank by means of the life cycle assessment and AHP method, the influence degree of carbon emission indexes in the whole life cycle of beer fermentation tank was obtained. The influence degree of carbon emission indexes in each stage of the whole life cycle of beer fermentation tank was 0.0801, 0.0477, 0.3092, 0.4811 and 0.0819, respectively. Through analysis, between stages of the whole life cycle of beer fermentation tank, the information integration, information exchange and information feedback mechanism are weak, which makes the carbon emission accounting difficult and the utilization rate of resources and energy low in the whole life cycle of beer fermentation tank, and the three green management strategies of beer fermentation tank, including the green design of beer fermentation tank based on modularization, intelligent manufacturing system of beer fermentation tank based on Internet+ and carbon dioxide recovery system based on recycling and reuse are put forward.
