Gestão de resíduos sólidos nas capitais do sul do Brasil: análise dos dados do sistema nacional de informações sobre a gestão de resíduos sólidos

Abstract

The proper management of solid waste is a problem present in most municipalities in the country. Approximately one third of the municipalities in the country carry out selective collection, sending many of the materials with the potential for reuse or recycling to sanitary landfills or dumps. Despite the mandatory disposal of waste in sanitary landfills established by the National Solid Waste Policy (PNRS), many municipalities still do not carry out proper disposal, which can cause environmental degradation and sanitation/public health problems, which is why it is necessary to establish instruments adequate management and control. This study aimed to analyze solid waste management data from the three capitals of the southern region of Brazil. From the analysis of the data National Information System on Solid Waste Management (SINIR), it was observed that the southern region of the country and its capitals stand out in relation to the collection of waste in their municipalities and the adequate disposal in sanitary landfills, however, they present a low percentage of recovery of the material collected selectively. Thus, the importance of municipalities adopting more effective public solid waste management practices to avoid the destination of their waste with potential for use in sanitary landfills, as provided for in the PNRS, is corroborated.
