摘 要:上海市城市生活垃圾自2019年分类收集后,基本实现干垃圾全部焚烧处置。回收干垃圾中的塑料类、纸类、玻璃类和金属类等可回收组分,用于生产相应的资源化产品,可以节约资源,减少垃圾焚烧处置产生的CO_(2)排放量。为研究干垃圾资源化利用的碳减排效益,对2021年上海市干垃圾的理化特性及组分进行了测定,并核算了全部干垃圾焚烧的CO_(2)排放量和塑料类、纸类、玻璃类、金属类组分资源化利用后再焚烧的CO_(2)排放量。结果表明,先资源化利用干垃圾中的塑料类、纸类、玻璃类和金属类组分,再对剩余的干垃圾焚烧处置,CO_(2)年排放量可比干垃圾全部焚烧处置削减81.09%。塑料类组分是焚烧处置CO_(2)排放的最主要来源,其排放占干垃圾中含矿物碳组分焚烧CO_(2)年排放量的98.54%,该组分资源化处置对削减干垃圾焚烧CO_(2)排放量具有决定意义。Almost all dry waste has been incinerated since the classified collection of municipal domestic waste in Shanghai from 2019.Recycling plastic,paper,glass and metal components from dry waste to produce corresponding resource-based products could save resources and reduce CO_(2)emissions of waste incineration.In order to study the CO_(2)reduction benefits of recycling of dry waste,the physico-chemical properties of dry waste in 2021 in Shanghai were measured.The CO_(2)emissions from incineration of all dry waste were calculated.And so were the CO_(2)emissions when the rest dry waste was incinerated after plastic,paper,glass and metal components were recycled.Results showed that the CO_(2)annua emissions when the rest dry waste was incinerated after plastic,paper,glass and metal components were recycled could be reduced by 81.09%compared with that from incineration of all dry waste.Plastic was the most important source of CO_(2)emissions when taking all dry waste incineration,which accounted for 98.54%CO_(2)annual emissions of dry waste with mineral carbon.So plastic was determinable to reduce dry waste incineration CO_(2)emissions.
