城市生活垃圾主要处理方式的温室气体协同减排效应比较——以天津市为例

根据天津城市生活垃圾(municipal solid waste,MSW)的构成与其含量,主要进行填埋气焚烧S1、填埋气发电S2和焚烧发电S3 3种城市生活垃圾处理方式的温室气体协同减排效应分析.以天津市滨海新区汉沽垃圾焚烧发电CDM项目、天津市双口生活垃圾卫生填埋场填埋气发电CDM项目为例,通过联合国政府间气候变化专门委员会(IPCC)提供的计算方法计算其温室气体排放量和减排量,并比较3种情景的协同减排.结果表明:S1、S2和S3的协同减排效应分别为0.602,t,CO2e/t,MSW、0.657,t,CO2e/t,MSW和0.777,t,CO2e/t,MSW,比较结果为S3S2S1.

Comparison of Collaborative Effects of Greenhouse Gas Emission Reduction Among Main Municipal Solid Waste（MSW） Disposal Ways——A Case Study of Tianjin

Based on the composition of Tianjin municipal solid waste（MSW） and its content, collaborative emission reductions of three main MSW disposal ways were analyzed, including landfill with landfill gas burned（S1）, landfill with landfill gas utilized（S2）, and incineration with electricity（S3）. Taking Tianjin Binhai municipal solid waste incineration power generation CDM project and Tianjin Shuangkou landfill gas recovery and electricity generation CDM project as examples, the calculation methods provided by Intergovernmental Panel on Climate Change（IPCC） Guidelines were used to calculate the greenhouse gas emissions and emission reductions, and then the collaborative emission reductions of the three scenarios were compared. Results show that the collaborative emission reductions of S1—S3 are 0.602 t CO2e/t MSW, 0.657 t CO2e/t MSW, and 0.777 t CO2e/t MSW respectively, so the comparison results is S3S2S1.
