摘　　要：为了量化建筑用岩棉生产过程的环境影响,采用Sima Pro8.0软件对我国典型岩棉制品生产开展了从"摇篮到大门"全生命周期评价。编制了岩棉生产的生命周期清单,计算了资源消耗、温室效应、酸化、光化学氧化、富营养化和人体毒性6种环境影响,并进行了归一化与贡献分析。结果显示:资源消耗和温室效应对环境的影响最为显著,分别占总环境影响值的45.4%和20.3%;成纤集棉阶段和原材料生产及运输阶段是造成环境影响的主要阶段,分别占总环境影响值的49%和29%。针对生命周期评价结果,提出了针对性的节能减排方案,使得环境影响值由2.64×10-13 yr减少为2.35×10-13 yr。A cradle-to-gate life cycle assessment （LCA） was carried out for rock wool production based on SimaPro8.0 soft- ware,in order to quantify environment impacts. Life cycle inventory for rock wool production was compiled. Abiotic depletion, global warming, acidification, photochemical ozone creation,eutrophication and human toxicity were considered in the phase of im- pact assessment. Normalization and contribution analysis were conducted. The results show that abiotic depletion and global wann- ing are the main environment impact categories in rock wool production,accounting for 45.4% and 20.3% of the total environmen- tal impact respectively. The processes of collection and raw materials production ＆ transportation present significant influence on the environment,with the contribution of 49% and 29%,respectively. According to LCA results,strategies on energy saving ＆ emis- sion reduction were suggested,which have been estimated to reduce environmental impact from 2.64×10^-13yr to 2.35×10^-13yr.
