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.
期刊介绍：
Energy addresses the challenges of energy engineering in the 21st century. The journal publishes groundbreaking papers on energy provision by leading figures in industry and academia and provides a unique forum for discussion on everything from underground coal gasification to the practical implications of biofuels. The journal is a key resource for engineers and researchers working to meet the challenges of energy engineering. Topics addressed include: development of sustainable energy policy, energy efficiency in buildings, infrastructure and transport systems, renewable energy sources, operation and decommissioning of projects, and energy conservation.
