基于生命周期评价方法量化分析典型企业生产建筑岩棉板“从摇篮到大门”的资源/能源消耗、污染物排放及潜在环境影响,辨识影响岩棉板产品环境负荷的关键过程及企业间差异性的主要因素。结果显示,岩棉板生产过程对全球变暖的环境影响贡献最大;原材料生产过程对矿产资源耗竭、化石能源耗竭及人体毒性的环境影响贡献显著;能源生产过程对颗粒物形成及陆地生态系统酸化的环境影响贡献最大;单位产品的能源消耗强度及玄武岩/树脂用量是造成不同企业岩棉产品环境影响差异的主要因素。

[Abstract]
Based on the life cycle assessment (LCA) method, this paper quantifies the resource and energy consumption, pollutant emission and potential environmental impact of typical enterprises producing rock wool board “from cradle to gate”, identifies the key processes affecting the environmental load of rock wool board products and the main factors of the difference between enterprises. The results show that the production process of rock wool board contributes the most to global warming. The process of raw material production contributes significantly to the environmental impact of mineral resource depletion, fossil energy depletion and human toxicity. The energy production process contributes the most to particulate matter formation and acidification of terrestrial ecosystem. The energy consumption intensity per unit product and the amount of basalt and resin are the main factors causing the environmental impact difference of rock wool products from different enterprises.
