Based on the method of life cycle assessment,we compared the environmental carbon emissions of the entire life cycle in the traditional way of mixed treatment mode and the separate recovery mode which will be implemented soon,for waste textiles and household waste in Shenzhen.The result showed that the environmental carbon emissions of 1t domestic waste during landfill disposal in Shenzhen were 1478.05 kg,342.97 kg during incineration and 221.31 kg respectively during recycling of waste textile.According to the current distribution in Shenzhen,the total carbon emission of Shenzhen for 1t domestic waste disposal was 797.00 kg during the entire life cycle and for 1t waste textile recycling was expected to be 754.24 kg.%采用生命周期评价方法对比深圳市生活源的废旧纺织品混合生活垃圾处理传统方式和即将实施的基于垃圾分类的单独回收处理2种模式的碳足迹(环境碳排放量).结果表明:每种模式的1t处理或回收中,废旧纺织品混合生活垃圾填埋处理环境碳排放为1478.05 kg,废旧纺织品混合生活垃圾焚烧处理环境碳排放为342.97 kg,废旧纺织品单独回收利用环境碳排放为221.31 kg.按照目前深圳市生活垃圾处理权重进行分配,可得深圳市处理1t生活垃圾整个生命周期过程中环境碳排放为797.70 kg,预期实施的废旧纺织品单独回收利用的生活垃圾处理生命周期环境碳排放为754.24 kg.
