摘要
“无废城市”建设是深化固体废物综合管理改革,实施减污降碳协同增效,助力实现碳达峰、碳中和战略的重要抓手。针对徐州市“无废城市”试点建设期间城乡生活、农业及工业等领域各类固体废物,参考WARM模型并采用排放因子法从源头减量至中端和末端处置环节的碳排放情况进行了全面核算,系统评估了徐州市“无废城市”试点建设与碳排放效益。结果表明,试点建设期间通过源头减量各类固体废物产生量,实现碳减排量1531.3×10^(4)t CO^(2)eq,其中工业领域固体废物源头减量贡献最大。各领域固体废物处置环节中,通过提高资源再生利用率、控制城市固体废物的填埋量、减少畜禽粪便的堆肥以及提升工业固体废物的资源回收利用是徐州市碳减排的重要措施。全市在试点建设期间实现碳减排效益1606.6×10^(4)t CO^(2)eq,总体上获得了较好的减污降碳协同效益。本研究结果可为推进“无废城市”建设与减污降碳协同增效提供参考。
The construction of“zero-waste zity”is an important policy to deepen the solid waste management reform,implement the synergetic control of environmental pollution and carbon emissions,and help achieve the carbon neutrality and emission peak.In this paper,the carbon emissions of solid wastes,focusing on urban and rural life,agricultural waste and industrial waste,were comprehensively accounted by the WARM model as well as the emission factor method from source reduction to mid-end utilization and terminal disposal.The benefits of carbon emission reduction were also systematically evaluated during the construction period of“zero-waste zity”in Xuzhou city.The results indicated that the carbon emission reduction reached 15.31 million tons CO^(2)eq through the source reduction of solid waste,of which the source reduction of the industrial solid waste contributed the most.It was an important measure to reduce carbon emissions by improving the recycling rate of resources,controlling the landfill volume of municipal solid waste,and decreasing the composting of manure during the disposal and utilization of solid waste.Xuzhou city achieved a carbon emission reduction benefit of 16.07 million tons CO^(2)eq,and generally obtained a better synergetic control of environmental pollution and carbon emissions.The results in this research might provide some reference for promoting the construction of“zero-waste zity”and synergizing the reduction of pollution and carbon emissions.
