Tratamento de resíduos sólidos no Município de Barueri: alternativas e soluções à luz da Política Nacional de Resíduos Sólidos

Abstract

This paper addresses the issue of solid waste treatment in Barueri municipality, located in the western region of São Paulo. In recent years environmental issues have been prominent on the national scene, especially after the effective date of the Federal Law 12.305/2010 establishing the National Solid Waste (PNRS). The new rule aims to mitigate the problems caused by the improper disposal of waste resulting from population growth, over-consumption and also by the absence of more effective public policies in all spheres of government. As an example, in 2011 were collected daily in Brazil 188.8 tons of trash. Of this total, 50.8 % of the municipalities in the waste sent to landfills, 25 % to controlled landfills and only 27.7% for regulated landfills. In order to reverse this PNRS to set some goals to be compressed by public managers that include: the closure of dumps and environmentally sound disposal of waste until August 2014; Preparation of municipal plans; shared responsibility for the life cycle of the product; implementation of selective collection, reverse logistics and composting. Further narrowed the priority to be followed in the management of solid waste, namely: reduction, reuse, recycling, solid waste treatment and final disposal of waste. Therefore, the aim of this study was to examine whether public policies concerning the treatment of solid waste, adopted by the municipal government of Barueri are in line with the goals set forth by Law 12.305/2010. The research methodology used was descriptive and quantitative. Regarding media is a bibliographic and documentary research. It was concluded that some actions taken by the municipal executive converge to the proposals of PNRS, for example, the closure and realignment of the former landfill to landfill licensed, the selective collection program with the inclusion of waste pickers, care of 100 % of population conventional collection, environmental education programs. However, as the rate of collection of recyclable materials, on average 3.11% of the total waste generated needs to be expanded, as well as wider dissemination of the composting process. On the other hand the alternative solution to the problem of the treatment and disposal of waste through the installation of incineration plant in course contradicts the order of priorities proposed by the standard.
