Análise do balanço financeiro de uma usina que poderia utilizar a vinhaça e a torta de filtro para fins geracionais ao invés da adubação

Abstract

Optimizing their profits to the maximum and at the same time being sustainable is the great challenge of large companies in our time, the sugar and alcohol industry is perhaps the best example that can be cited, practically everything is used and reused in its processes. The implementation of a biodigester can further contribute to these contemporary values, using vinasse and filter cake to generate energy through biogas or biomethane, while using decomposed matter in fertilization. The objective of this work is to evaluate the financial balance of an industry that could use its vinasse and filter cake for energy production and not just for fertilization. Thus, a case study was carried out with Usina Alto Alegre, calculating the generation of biogas or even biomethane for cogeneration and its commercialization, analyzing the investment for this, the expected time to make a profit.
