摘要
产品生命周期评价系统和数据库为高效、准确开展产品生命周期评价提供数据处理、结果量化和评价支撑。本文对纺织产品生命周期评价研究文献中应用的生命周期评价系统与数据库系统界面、数据库和影响评价模型数量、特征化因子、归一化因子、权重因子等进行了系统分析。结果表明:Simapro系统和Gabi系统是纺织产品生命周期评价案例使用最多的系统,总占比为53.77%;Ecoinvent数据库和Gabi数据库是纺织产品生命周期评价案例使用最多的数据库,总占比为79.24%;Simapro系统和Gabi系统内置数据库有相同种类但数值不同的特征化因子、归一化因子、权重因子,导致使用两个系统针对同一纺织产品的生命周期评价结果存在差异;综合考虑污染物排放渠道和区域内生产规模、科技水平、经济状况、环保政策等因素,构建具有国家、区域、时间性质的纺织产品LCA数据库可以提高评价结果的完整性和准确性。
Life cycle assessment(LCA)is a comprehensive method to identify and evaluate the environmental impact of a product or a process throughout the life cycle,which can effectively identify the key stages of the environmental impact of a product's life cycle and thus provide important and accurate guidance for the development of energy conservation and emission reduction strategies.Due to the long and complex supply chain and manufacturing processes,the textile industry is inevitably one of the most pollutant industries around the world.Therefore,conducting life cycle assessment and selecting the appropriate LCA systems and databases for textile products and production processes are of vital significance.China is one of the largest producers and consumers of textile products around the world.LCA of textile products is an effective tool to quantify the environmental impacts generated by the production and consumption of textile products,which further provides valid references for green and low-carbon textile product design,production and consumption.Data collection and result evaluation are two key aspects of product LCA.Using LCA system and its built-in database of impact factors for energy,materials and other input lists can greatly improve the efficiency and accuracy of LCA for products.In order to conduct a systematic and comprehensive analysis of LCA systems and databases for textile products,we firstly searched literature pertaining to product LCA research on China National Knowledge Infrastructure(CNKI)and Web of Science and summarized the product LCA systems and databases applied in the literature.Considering that LCA of textile products is receiving increasing attention and research,we then searched the literature on LCA research of textile products and analyzed the assessment systems and databases applied in literature.According to the fiber category,the literature found was classified and the impact models and LCA databases used were listed and compared.In addition,we systematically analyzed and compared the
