摘要
结合城市生活垃圾管理系统特征,系统归纳基于生命周期评价(Life cycle assessment,LCA)方法的城市生活垃圾管理模型的发展现状,并对LCA方法在城市生活垃圾管理中的实践以及在我国开展城市生活垃圾管理LCA研究的应用前景进行评述。分析表明,LCA是城市生活垃圾管理领域的重要工具之一,基于LCA方法的城市生活垃圾管理模型在全生命周期环境影响评价与识别、处置工艺选择与改进、可持续生活垃圾管理决策支持等方面具有十分重要的应用价值。中国在本地化生活垃圾管理系统LCA模型开发、清单数据库和评价指标体系构建以及与其他研究方法集成等方面面临挑战。
Considering the characteristics of municipal solid waste （MSW） management systems, this study conducted a thorough overview of life cycle assessment （LCA）-based models that can be used to support policy decisions on MSW management. A number of MSW management practices using LCA-based models were reviewed at different levels. The application foreground of LCA-based models in China＇s MSW management was also discussed. This study assessed the applications of LCA-based models in MSW management. We found that LCA is one of those important systematic tools that can be used to support MSW management. LCA models are important to the assessment and identification of life cycle environmental impacts of MSW treatment technologies, the choices and improvements of those technologies, and the policy decisions for MSW management. China is facing great challenges in LCA studies on MSW management, including the development of China-specific MSW management models, the construction of China-specific life cycle inventory databases and life cycle environmental impact indicator systems for MSW, and the integration of interdisciplinary methods.
