When exploring the correlation between municipal solid waste management and green house gas emission, the volume and physical composition of the waste matter must be taken into account. Due to differences in local environments and lifestyles the quantity and composition of waste often vary. This leads to differences in waste treatment methods and causes different volumes of greenhouse gases (GHGs), highlighting the need for local research. In this study the Life Cycle Inventory method was used with global warming indicator GHGs as the variables. By quantifying the data and adopting a region-based approach, this created a model of household MSWM in Taipei City, a metropolitan region in Taiwan. To allow analysis and comparison a compensatory system was then added to expand the system boundary. The results of the analysis indicated that out of all the solid waste management sub-models for a function unit, recycling was the most effective method for reducing GHG emissions while using kitchen food waste as swine feeding resulted in the most GHG emissions. As for the impact of waste collection vehicles on emissions, if the efficiency of transportation could be improved and energy consumption reduced, this will help solid waste management to achieve its goal of reducing GHG emissions.
在探究城市固体废物管理与温室气体排放之间的相关性时,必须考虑废物的体积和物理成分。由于当地环境和生活方式的差异,废物的数量和成分往往各不相同。这导致了废物处理方法的差异,并产生了不同数量的温室气体(GHG),凸显了开展本地研究的必要性。在本研究中,使用生命周期清单法,将全球变暖指标温室气体作为变量。通过对数据进行量化并采用基于区域的方法,构建了台湾大都市地区台北市的家庭城市固体废物管理模型。为了进行分析和比较,随后添加了一个补偿系统以扩大系统边界。分析结果表明,在功能单元的所有固体废物管理子模型中,回收是减少温室气体排放最有效的方法,而将厨余垃圾用作猪饲料则导致温室气体排放最多。至于垃圾收集车辆对排放的影响,如果能够提高运输效率并降低能源消耗,将有助于固体废物管理实现其减少温室气体排放的目标。
