Sustentabilidade e desenvolvimento regional: uma análise do potencial econômico dos resíduos sólidos urbanos no Oeste do Paraná 1970 - 2020

Abstract

The various activities inserted in the production processes are characterized by the generation of common solids (MSW) waste, whether in solid, liquid or gaseous. Therefore, this study aims to identify factors capable of explaining the economic potential of MSW as a sustainable regional development factor, transforming the problem of MSW generation in new business opportunity. For this purpose, the methodology included the implementation of steps to characterize the source of MSW municipalities under study, analysis of the models and technologies used in MSW, and identification of potential bottlenecks in the economic sectors and the systematization of results by presenting a new economic model using MSW as inputs in production processes. The results showed that the municipalities under study had an average generation of 54.5 t / day of plastic; 12 t / day of glass; 6:06 l t / day of metal; 60.6 tons / day of paper; 5.5 ton / day from other waste types and 418.5 tons / day of organic. It was identified that the marketing of MSW aluminum, cardboard and PET is more expressive in the states of São Paulo, Minas Gerais and Paraná. From this information it was possible to estimate the total gross revenue for the 30 municipalities in the study, which was approximately R$ 3,642,408.38, of which this was more notable in the municipalities of Cascavel, Foz do Iguacu and Toledo , which together were responsible for obtaining 57% of the total gross revenue for the cities analyzed. The systematization of the results showed that the new model of MSW, send about 5.6 tonnes/day of MSW to the municipal landfill of Toledo, representing a reduction of 92% of the total previously forwarded by using the traditional management model MSW. Thus, the development of this new management model would help the sustainable development of meso study, it would be able to generate income from the implementation of new models of factories, developing new technologies, increased service life and reduced need for increased of area landfills and thus will make the municipalities fall under the guidelines of the law 12.305/2010 PNRS.
