摘要

研究基于全生命周期方法,界定了餐厨垃圾收运与处理全过程核算边界,识别温室气体排放源和排放种类建立排放源清单,基于排放因子法构建了可拆分的餐厨垃圾收运与处理全过程温气体排放核算模型.研究结果发现,餐厨垃圾收运与处理全过程核算边界包含9个核算单元,温室气体排放源主要分为7类.相较于传统模型,该模型具有可拆分､可组合､模块化的特点,在核算精度､模型灵活性以及场景适应性上有显著优势;本研究以北京市朝阳区的餐厨垃圾收运与处理全过程为例进行核算.研究结果显示,垃圾投放点和车辆行驶环节的温室气体排放量较为突出,分别为1.38和1.32tCO₂e/d,化石燃料燃烧是其主要的排放源占总排放量的24.4%.在处理处置阶段,废水处理环节的温室气体排放量最高,达4.05tCO₂e/d,占总排放量的32.3%.碳补偿共减少了53.2tCO₂e/d.敏感性分析结果显示餐厨垃圾量和沼气产量对温室气体排放的影响较为显著,而车辆行驶总公里数和电力因子的影响相对较小.

Abstract

This study adopts a life cycle assessment (LCA) framework to define the system boundary for greenhouse gas (GHG) emission accounting across the entire food waste collection, transportation, and treatment process. Emission sources and gas types were identified to establish a comprehensive emission inventory, upon which a modular and decomposable GHG emission accounting model was developed based on the emission factor method. The results indicate that the full-process system boundary encompasses nine accounting units and seven major categories of GHG emission sources. Compared to conventional models, the proposed model demonstrates distinct advantages in accounting accuracy, modularity, flexibility, and scenario adaptability. A case study was conducted for the Chaoyang District of Beijing to validate the model. The findings show that GHG emissions are particularly significant at the waste disposal sites and during vehicle transportation, with emission rates of 1.38 and 1.32 tCO₂e/d, respectively. Fossil fuel combustion was identified as the dominant emission source, contributing 24.4% of total emissions. In the treatment and disposal phase, wastewater treatment exhibited the highest emissions, reaching 4.05tCO₂e/d, or 32.3% of the total. Carbon offsetting efforts achieved a reduction of 53.2tCO₂e/d. Sensitivity analysis revealed that food waste generation volume and biogas yield have the most significant impact on total GHG emissions, while the influence of total vehicle kilometers traveled and electricity emission factors was comparatively minor.
