用生命周期评价优化家庭的洗涤

Application of social life-cycle analysis as an analytical tool for optimizing home laundry

提出一种社会化的生命周期评价(LCA)方法,取代经典的ISO-LCA方法优化家庭的洗涤。采用实际调查及人工污布试验的方法,研究了由于最近人们的生活方式、洗衣机的节能化和洗涤剂浓缩化等因素引起的洗涤过程的变化,比较了不同年代、不同容量的全自动洗衣机对洗涤的影响,对洗涤过程中的洗涤剂、用水和耗电量进行了社会化的LCA分析。研究表明,最近制造的节水型全自动洗衣机已大大减少了CO2排放量,并指出减少洗涤过程CO2排放量的途径。
