Abstract: The objective is to develop a model to support decision-making in the management of municipal solid waste (MSW) through life cycle sustainability assessment (LCSA). The methodology consists in the creation of alternative MSW management scenarios, evaluating environmental sustainability throughout the life cycle assessments (LCA), economical sustainability throughout the life cycle cost (LCC) assessment and social sustainability throughout the social life cycle assessment (SLCA). The analyses were integrated through the LCSA and a three-dimensional weighting and analysis of the indicators was carried out through the multicriteria analysis. The model can assist in the decision support process for sustainable management of MSW in Brazilian municipalities.

Keywords: sustainable development; life cycle; municipal solid waste; MSW; multi-criteria analysis; Brazil.
