废皮革水泥窑共处置生命周期评价

以废皮革为典型固体废物开展水泥窑共处置试烧试验.以生命周期评价方法(LCA)为研究手段，对水泥窑共处置技术的环境影响进行评价，并与常规水泥生产过程作比较.结果表明:常规水泥生产过程的综合环境负荷为7.028×10-12 a-1，其中最大的环境负荷为全球变暖，达3.368×10-12 a-1.当废皮革作为替代燃料在水泥窑中共处置时，可减少燃煤的使用量，同时降低CO₂的排放，降低了能源消耗、人体健康损害等方面的环境压力；其综合环境负荷为6.618×10-12 a-1，比常规水泥生产降低了5.83%. 

LCA on Co-Processing Waste Leather in Cement Kilns

Waste leather was chosen as a typical solid waste for an experiment of co-processing solid waste in a cement kiln.The environmental impact of co-processing technology in cement kiln was evaluated by life cycle assessment (LCA) as a tool，and the result was compared with normal production.The result showed that the environmental load index of normal production was 7.028×10-12 a-1.The largest part of the environmental load was global warming potential(GWP) (3.368×10-12 a-1).Co-processing waste leather as alternative fuel (AF)can reduce the coal consumption and the emission of CO₂，so that the environmental loads of energy depletion potential(EDP) and human toxicity(HT) are reduced significantly.The total environmental load was 6.618×10-12 a-1，reduced by a rate of 5.83% compared with normal production.
