Indicadores e índice de qualidade (IQGRSU) como ferramentas de sustentabilidade para a gestão de resíduos sólidos em Manaus/AM

Abstract

The objective of this study was to evaluate the sustainability of municipal solid waste (MSW) management in the city of Manaus/AM, by constructing an Indicator Matrix and estimating the MSW Management Quality Index (IQGRSU). The methodology was based on a systematic review of the literature and the application of the GUT (Gravity, Urgency, and Trend) matrix to identify and classify indicators in the environmental, social, economic, and governance/policy dimensions. The results showed that the IQGRSU of 4.0 classifies Manaus' MSW management as unsatisfactory in terms of sustainability, with weaknesses predominantly in the environmental dimension, highlighting the existence of degraded and irregularly disposed areas, unrecovered environmental liabilities, saturation of the treatment system, and limited useful life of the landfill. On the other hand, the social and governance dimensions showed moderate performance, reflecting specific advances in selective collection and awareness campaigns. As a main suggestion, we propose improving integrated governance and municipal planning, updating the Integrated Solid Waste Management Plan (PMGIRS), expanding Voluntary Delivery Points (PEVs), and stimulating the circular economy through public-private partnerships and the inclusion of waste picker cooperatives. It is concluded that the methodology applied, integrating the GUT Matrix and the IQGRSU, proved effective in diagnosing the performance of MSW management in Manaus, providing technical support for the formulation of guidelines and public policies aimed at sustainability and the continuous improvement of urban waste management.
