基于中国某水泥厂2022～2023年生产数据及近3年国家/行业统计数据进行生命周期评价,核算水泥窑协同处置城市生活垃圾(MSW)生产不同品种水泥的环境负荷;联合数据质量指标评估和蒙特卡洛模拟来综合评估最终结果的不确定度.与常规工艺相比,水泥窑协同处置工艺生产每吨熟料的综合环境负荷降幅为7.82%;4种水泥中,P·O 52.5水泥的综合环境负荷最大,但其单位强度的环境负荷相对较小.综合考虑,采用水泥窑协同处置工艺生产P·C 42.5水泥与采用常规工艺生产P·O 42.5水泥相比,其综合环境负荷降幅为16.87%.
Coupling Evaluation of Environmental Load and Mechanical Properties for Co-processing of MSW in Cement Kiln
Based on the production data from 2022 to 2023 in a typical plant in China and national and industrial statistics from the past three years,a life cycle assessment(LCA)was conducted for cement production.The environmental load of co-processing of municipal solid waste(MSW)in cement kiln was calculated,and the differences in environmental load per unit strength of different cements were compared.Moreover,the uncertainty of the LCA result was evaluated by data quality indicator and Monte Carlo simulation.Compared with conventional production,the integrated environmental load indicator of one ton of clinker was reduced by 7.82%in the co-processing production.Among the four types of cement,Portland cement P·O 52.5 had the highest integrated environmental load indicator,but its environmental load per unit strength was relatively smaller.Compared with the production of Portland cement P·O 42.5 by conventional clinker production,the integrated environmental load indicator of the production of Portland cement P·C 42.5 by co-processing production was reduced by 16.87%.
