Abstract

Life cycle assessment (LCA) is one of the best tools to determine the environmental impact of municipal solid waste (MSW) management. This work analyzed the best-evaluated MSW management options in the world with LCA, to identify future trends. 132 LCA publications (2015-2023), their geographical distribution, and the results obtained according to the ISO 14040 standard were considered; The options evaluated were also compared with those reported by the World Bank. The results showed that the majority of publications come from the Europe and Central Asia region, followed by Latin America and the Caribbean. After comparing the alternatives, it was observed that open dumps and controlled sites will tend to be replaced by landfills with energy recovery in all regions of the world; the technologies for recovering materials and using the organic fraction will continue to be applied; and alternative processes will become more common. This work aims to support decision-making for the selection of treatments and improve the management of MSW according to geographical conditions, as well as the development of strategies to respond to the 2030 agenda.

Keywords
