Análise da viabilidade econômica do projeto de aproveitamento de energia e eficiência energética para frigorífico

Abstract

The present study aims to analyze the economic viability of implementing an investment project (IP) allowing the reuse of thermal energy present in wastewater in a poultry processing unity located in the city of Pato Branco in Paraná state, to reduce the electricity consumption o. The research is an applied quantitative case study, using as an analysis tool the web application VPI. Calculations were made using projections with a 10-years horizon To discount the projected cash flow, according to the current SELIC (Special System for Settlement and Custody), a Minimum Attractiveness Rate of Return (MARR) of 6,5% per year was used. It was found that the IP has a positive Net Present Value (NPV) of R$ 190, 595.37, in 10 years with a gain expectation of 5.20% in addition to the TMA (6.5%). The investment total return is R$ 479, 565.37 and the ROI / MARR ratio is 79.94%. The investment value is recovered in 6 years. Regarding risks payback / N is 60% and MARR /IRR 34.7%. Regarding the elasticity limits, the project is economically viable, but it indicates special attention in the monitoring and control process for the Cash Flow (CF) variable, which is the most sensitive. Regarding the environmental impact, the implementation of IP generates a reduction in electric energy consumption, reusing the energy taken from the thermal load of sewage, a factor that contributes to the viability of IP
