垃圾焚烧发电项目碳排放核算与减排效应研究

Carbon emission calculation and reduction effects of municipal solid waste incineration power generation project

采用IPCC国家温室气体清单指南法计算了合肥市某生活垃圾焚烧发电项目的碳排放,分析了项目碳减排效应,并给出了垃圾焚烧的减排路径。结果表明,该生活垃圾焚烧发电项目碳排放强度为398.89 kgCO_(2)e/t,其中焚烧过程碳排放为384.7 kgCO_(2)e/t,占比96.44%。塑料等含化石碳组分垃圾的碳排放占整个焚烧项目碳排放的92%以上,是主要排放源。项目通过替代垃圾填埋基准线排放为557.75 kgCO_(2)e/t,替代燃煤发电的基准线排放为385.73 kgCO_(2)e/t,综合净减排量为544.59 kgCO_(2)e/t,表明生活垃圾焚烧发电项目具有很好的减排效益。通过系统规范核算了焚烧发电项目温室气体排放的基础数据,为垃圾焚烧发电行业摸清碳排放底数、参与碳排放交易等提供支撑。

The carbon emission of the municipal solid waste(MSW)incineration power generation project in Hefei is calculated by using the IPCC national greenhouse gas inventory guidance method,and the carbon emission reduction effect is also analyzed.Moreover the emission reduction path for MSW incineration is also clarified.The results show that the carbon emission intensity of the MSW incineration power generation project is 398.89 kgCO_(2)e/t in total,and the carbon emission during incineration is 384.7 kgCO_(2)e/t,accounting for 96.44%.Plastics and other wastes containing fossil carbon components account for more than 92%of the carbon emissions of the whole incineration project,which is the main emission source.The baseline emission of the project through the alternative landfill is 557.75 kgCO_(2)e/t.And the baseline emission of the alternative coal-fired power generation is 385.73 kgCO_(2)e/t.The comprehensive net emission reduction is 544.59 kgCO_(2)e/t,indicating that MSW incineration has great benefits for carbon emission reduction.Through the standardized calculation of the basic data of carbon emission of MSW incineration projects,it provides support for the industry to find out the base data of carbon emission and participate the carbon emission trading.
