ANÁLISE DA VIABILIDADE DA CONSTRUÇÃO DE UM ATERRO SANITÁRIO NO MUNICÍPIO DE RANCHARIA (SP) POR MEIO DE ENGENHARIA ECONÔMICA

Abstract

This study aimed to analyze the feasibility of building a landfill in the municipality of Rancharia-SP, aiming to meet the standards established by the National Solid Waste Policy (PNRS), reduce costs with the proper disposal of waste, reduce environmental pollution and avoid possible penalties imposed by the Environmental Company of the State of São Paulo (CETESB). A quantitative approach was carried out to verify the economic viability of investment alternatives, with the application of Economic Engineering methods, such as the Net Present Value (NPV) method. The information needed for the analysis, regarding the projections of solid waste generation by the municipality of Rancharia, the costs of outsourcing the proper disposal of waste, the costs of the life cycle stages of a landfill, were raised through research bibliographic and documentary. Thus,and considering that, so far, the municipality pays for the transshipment and the proper disposal of its waste at the landfill of a neighboring municipality (23km), it was concluded that the construction of a landfill in Rancharia -SP is the alternative more economically profitable, being able to present better returns with the realization of financing, whose rates are lower than the opportunity cost, as well as with the implementation of more efficient systems of selective collection of recyclable materials.
