摘　　要：结合我国玻璃纤维产业现状,采用生命周期评价(LCA)方法对玻璃纤维从“摇篮”到“大门”的资源/能源消耗、污染物排放进行清单编制和环境影响潜力分析。结果表明,人体致癌毒性(HTPc)、人体非致癌毒性(HTPnc)对环境影响较大,分别占53.51%、30.53%。原料熔制阶段对全球变暖效应(GWP)、颗粒物形成(PMEP)、光化学臭氧形成对生态系统的影响(EOFP)、陆地酸化(AP)、人体致癌毒性(HTPc)、人体非致癌毒性(HTPnc)、化石能源耗竭(FFP)的贡献均最大,分别占78.57%、72.87%、66.00%、78.16%、71.69%、88.90%和78.10%。将生产玻璃纤维整个过程使用的电力改变电力结构时,碳排放呈一定幅度下降,7项环境影响指标均下降,可有效降低环境影响。Combined with the current situation of glass fiber industry,this study uses the life cycle assessment(LCA)method to investigate the resource and energy consumption and pollutant emission of glass fiber from the“cradle”to the“gate”,compile the inventory,and characterize and normalize the data by using the recipe analysis method.The results show that human carcinogenic toxicity(HTPc)and human non carcinogenic toxicity(HTPnc)have a great impact on the environment,accounting for 53.51%and 30.53%,respectively.The ingredient melting phase contributes greatly to global warming potential(GWP),fine particulate matter formation(PMEP),photochemical ozone formation on terrestrial ecosystems(EOFP),terrestrial acidification(AP),HTPc,HTPnc,fossil resource scarcity(FFP),accounting for 78.57%,72.87%,66.00%,78.16%,71.69%,88.90%,and 78.10%,respectively.When the power structure in the whole process of producing glass fiber is changed,the carbon emission shows a certain decrease,and the seven environmental impact indicators are reduced,which can effectively reduce the environmental impact.
