GREENHOUSE GAS EMISSIONS FROM WASTE DISPOSAL UNITS AND THEIR REDUCTION POTENTIAL: A CASE STUDY IN QINGDAO

College of Environmental and Municipal Engineering, Qingdao Technological University, Qingdao 266520, China

摘要

摘要: 生活垃圾处理处置单元是重要的温室气体（GHG）排放源，明确其排放变化趋势及特征，降低其GHG排放，对于缓解全球温室效应，助力我国实现“碳达峰”“碳中和”目标具有重要意义。以青岛市为例，采用IPCC清单模型分析了青岛市2010—2020年生活垃圾处理处置单元GHG排放情况。结果表明：青岛市垃圾处理处置单元GHG排放量从2010年的131.3万t CO₂-eq增加到2016年的223.77万t CO₂-eq，2020年GHG排放量下降为95.05万t CO₂-eq；2019前填埋场CH₄排放是最主要的温室气体排放源，2020年后则以焚烧厂CO₂排放为主，随着焚烧比例的增加，2020年青岛市焚烧GHG排放占比达72.8%。推行生活垃圾分类，提高填埋气体（LFG）收集效率，强化覆盖层甲烷（CH₄）氧化，转变生活垃圾处置方式（填埋转向焚烧），提高可回收垃圾回收率等是实现城市生活垃圾处理处置单元GHG减排的有效措施。

Abstract: Municipal solid waste (MSW) treatment and disposal units are an important source of greenhouse gas (GHG) emissions. Clarifying the trend and characteristics of its emissions changes and reducing its GHG emissions is of great significance for alleviating the global greenhouse effect and helping China achieve the goals of "carbon peaking" and "carbon neutrality". The IPCC inventory model was used to evaluate the GHG emissions from MSW treatment and disposal units in Qingdao from 2010 to 2020. The results showed that GHG emission from MSW in Qingdao increased from 1.131 million tons CO₂-eq in 2010 to 2.238 million tons CO₂-eq in 2016, and decreased to 0.950 tons CO₂-eq in 2020; the most emitted GHG, changed from CH₄ from MWS landfills before 2019, to CO₂ from MSW incinerator in 2020. As the proportion of incineration increased, the share of incineration GHG emissions in Qingdao reached 72.8% in 2020. Achieving domestic waste classification, improving landfill gas (LFG) collection efficiency, strengthening methane (CH₄) oxidation in the cover layer, changing domestic waste disposal methods from landfill to incineration, and improving recyclable waste recovery efficiency are effective measures to achieve GHG emission reduction from MSW disposal units.
