A (in)viabilidade de consórcios públicos intermunicipais para a gestão de resíduos sólidos no Amazonas

Abstract

The aim of the present study was to analyze the feasibility of implementing inter-municipal public consortia for solid waste management in the Amazonas state. The research is descriptive as to the objectives, bibliographical, documentary and field as the procedures and quantitative approach. The data were obtained through the application of online questionnaires, forms, in semi-strutured interviews and preparation of technical maps. Initially, indicators were defined for the evaluation of the implementation of inter-municipal public consortia for solid waste management (CPIGRS) through the Delphi Method, and at the end of consultations, 30 indicators were defined. These were validated by applying questionnaires to municipal managers, obtaining a value of 82.4% of viability. Subsequently, the diagnostics of the solid waste management systems of the municipalities of Silves and Itapiranga were raised through indicators previously established by the literature and the CPIGRS indicators, in addition to the application of the Ditch Waste Landfill Quality Index (IQR-Valas), obtaining negative results in both analyzes. Finally, the areas for the possible construction of sanitary landfills were delimited and the costs that each municipality would have had if a landfill were built in isolation and consortium were raised. After analyzing the environmental, social and political criteria involving CPIGRS, and reclassifying them into CPIGRS indicators, the municipalities had a viability result of 94.4%. Finally, the study concluded that there are benefits in the five dimensions if CPIGRS is implemented, however, pointing out that the economic and political dimensions are responsible for the non-implementation of consortia in the state, especially for maintaining a high value for the construction of a landfill as well as lack of priority of municipal managers to equalize the problem of waste in their respective municipalities.
