ANÁLISE DE VIABILIDADE ECONÔMICA DO PROJETO DE APROVEITAMENTO ENERGÉTICO DE BIOMASSA DE ALGODÃO EM UMA INDÚSTRIA DE FIAÇÃO

Abstract

The present work shows the analysis of the economic feasibility of the project for the acquisition of a pellet mill, aiming to replace the conventional eucalyptus biomass by the Micropowder generated by the textile industry studied. To find an appropriate destination for this waste, a project was developed that aims to use it through pelletizing, allowing it to be used in the boiler together with chips. The research considered three distinct scenarios: optimistic, probable and pessimistic, with biomass replacement rates defined for each of them. The results showed that, with a replacement of 8.83% of chips by Micropó, it had the highest NPV (R$ 32,855.25) and an IRR of 20%, with a projected Payback of 4.17 years. In the probable scenario, with an exchange of 7.06%, the NPV reached R$ 11,341.19 and the IRR was 14%, while the Payback was calculated at 5.22 years. In the pessimistic scenario, it resulted in 4.41% of Microdust, the NPV was negative at R$ 20,754.18, with an IRR of 3% and Payback of 8.34 years. It was possible to evaluate the potential use of cotton biomass in the boiler feed as an alternative to add value to the waste and, thus, enable the return on investment.
