Análise da viabilidade de implantação de usina de esíduos sólidos da construção (RCC) em Jataí (GO)

Abstract

Civil Construction plays an important role in the development of Brazil, but it is a major generator of socio-environmental impacts. In Jataí (GO), the disposal and destination of RCC are inadequate. Thus, the objective of this work was to analyze the economic viability for the implementation of a RCC recycling plant, through bibliographical, documental and field survey. According to official data, Jataí generates 3,761 m³/day of Class A RCC, estimating 4,513.20 ton.RCC/month. The plant's processing capacity was sized at 25 t/hour and the production of recycled aggregates with a selling price of 57.43% lower than the natural aggregate sold in Jataí. In the economic analysis, indicators were used to project the plant's cash flow, applying financial metrics such as NPV, IRR and Payback, creating two scenarios (public and private company) for the study. The initial investment was BRL 4,929,782.17 and an annual operating cost of BRL 727,940.95, for both scenarios. The initial billing forecast for the first year was BRL 1,203,937.52 for a public company and BRL 919,951.39 for a private company, with a rate of 6.47% per annum. For the public company, a NPV of + R$ 7,895,134.42 was obtained, an IRR of 33.86%, an ILL of 2.60 and a PB of 4.35 years. The private company was granted a NPV of + R$3,901,251.15, an IRR of 24.56%, an ILL of 1.79 and a PB of 5.51 years. Therefore, both are positive and economically viable for Jataí society.
