Análise de Viabilidade Econômica para Sistemas de Tratamento de Resíduos Sólidos Urbanos no Município de Marechal Cândido Rondon – PR

摘要

The disposal of solid residues has been a critical factor in urban management. Sanitary landfilling treatment systems predominate, but new alternatives have been developed, supported by high-tech. Nevertheless, financial investment exerts a strong restriction to that choice. Thus, is it economically viable to implement an Alfa equipment to replace sanitary landfills? This study aimed to measure the costs of landfilling and to implement a heat treatment system. The methodology was an applied and exploratory research characterized as a case study in the municipality of Marechal Cândido Rondon, in the State of Paraná. The results demonstrate that such a replacement is not economically viable, and sanitary landfilling is still the chosen method.. The new technology has a great environmental and social potential, essentially in the cities where physical space is very restricted or costly.
