Decision Model for Selecting Advanced Technologies for Municipal Solid Waste Management

Abstract

The National Solid Waste Policy (PNRS) was implemented in 2010; it aims to prevent and reduce waste generation, eliminate the so-called ‘landfills’ and implement municipal solid waste management plans. Waste selective collection and recycling can reduce the amount of waste destined to landfills, reduce transportation frequencies and minimize overall disposal costs. However, the conventional approach currently adopted in Brazil is inefficient considering economic, social and environmental aspects. There is an urgent need to improve municipal solid waste management (MSWM) by proposing alternatives, which cover product-service systems (PSS) and IoT based smart trash dustbins. This study provides an assessment through multicriteria analysis whether the implementation of scenarios using IoT smart trash cans is to be considered a sustainable operational strategy for the municipal public administration. The criteria used in the study was extracted from a systemic literature review; AHP and TOPSIS Fuzzy Methods were applied to achieve the best solution according to the selected criteria, which is the research main objective.
