Life cycle assessment for solid waste management: a case study of Hue City

Abstract

Life cycle assessment (LCA) is a decision support tool used worldwide, and currently, it is also applied to solid waste management. In this research, we built four SWM scenarios for Hue City. The scenario life-cycle impacts were assessed by using the IMPACT 2000+ method and implemented on the OpenLCA software to decide the most environmentally friendly solid waste management solution for Hue City. The results indicate that the S4 scenario – Waste to energy (–2,1 point impact) is the most environment-friendly. The S1 scenario – Landfill (0,218 point impact) is the worst scenario related to the environmental effects aspect. Landfill gas collection (landfill gas to energy) and recycling have reduced the adverse effects on the environment.
