The Municipal Solid Waste Management (MSWM) sector has developed considerably during the past century, paving the way for maximum resource (materials and energy) recovery and minimising environmental impacts such as global warming associated with it. The current study is assessing the historical development of MSWM in the municipality of Aalborg, Denmark throughout the period of 1970 to 2010, and its implications regarding Global Warming Potential (GWP(100)), using the Life Cycle Assessment (LCA) approach. Historical data regarding MSW composition, and different treatment technologies such as incineration, recycling and composting has been used in order to perform the analysis. The LCA results show a continuous improvement in environmental performance of MSWM from 1970 to 2010 mainly due to the changes in treatment options, improved efficiency of various treatment technologies and increasing focus on recycling, resulting in a shift from net emission of 618 kg CO(2)-eq.tonne(-1) to net saving of 670 kg CO(2)-eq.tonne(-1) of MSWM.
在过去的一个世纪里，城市固体废物管理（MSWM）领域得到了极大的发展，为最大限度地回收资源（材料和能源）铺平了道路，并最大程度地减少了与之相关的全球变暖等环境影响。本研究使用生命周期评估（LCA）方法，评估了丹麦奥尔堡市 1970 年至 2010 年期间的 MSWM 历史发展及其对全球变暖潜能值（GWP(100)）的影响。为了进行分析，使用了有关 MSW 成分和不同处理技术（如焚烧、回收和堆肥）的历史数据。LCA 结果表明，1970 年至 2010 年期间，MSWM 的环境绩效不断提高，主要原因是处理选择的变化、各种处理技术效率的提高以及对回收的日益重视，导致从净排放量 618kgCO2-eq.吨（-1）转变为净节约 670kgCO2-eq.吨（-1）的 MSWM。
