Abstract

A life cycle assessment of waste management in Pyongyang, Korea was undertaken using a characterisation-based method to analyse cumulative energy demand and energy-related carbon dioxide emissions. The study showed that characterising waste fractions by composition, proportion, water content and heating value rather than simply mass was more effective for energy-related analysis in life-cycle assessments. The results indicated that the energy demand and emissions indicators could be used as appropriate proxies of the environmental impacts in life-cycle phases, since they were closely related. The results also revealed that waste incineration could result in energy credit to the national electricity mix, while waste landfill needed to be replaced with sanitary landfill and/or switched to incineration with energy recovery to be more sustainable.

分析城市固体废物的特征，以分析生命周期的能源需求和排放

使用基于特征的方法对朝鲜平壤的废物管理进行了生命周期评估，以分析累积能源需求和与能源相关的二氧化碳排放。这项研究表明，对生命周期评估中的能源相关分析而言，按组成、比例、含水量和热值而不是简单的质量来描述废物组分的特征更为有效。结果表明，能源需求指标和排放指标具有密切的相关性，可以作为生命周期阶段环境影响的合适替代指标。研究结果还表明，垃圾焚烧可以为国家电力结构带来能源信贷，而垃圾填埋需要用卫生填埋取代，或者改用焚烧和能源回收，以提高可持续性。
