Abstract:
Brazil occupies the position of second largest ethanol producer in the world, largely using hydrated ethanol in flexible-fuel vehicles and fuel mixtures with addition of anhydrous ethanol to gasoline. In the Brazilian harvest of 2019/2020 were processed 642.6 million tons of sugarcane. Sugarcane cultivation promotes the production of several residues from the field to industrial processing, being bagasse and vinasse the most expressive in quantitative terms. To make it possible to implement a waste biorefinery, previous characterization studies are necessary to indicate their potential and the possibility to integrate industrial and biotechnological processes. Thus, the present study aimed to present an overview of the Brazilian sugar-energy sector, encouraging the implementation of sugarcane vinasse biorefineries and expanding the ethanol productive chain sustainability, using fermentative routes, microalgae cultivation and complementary processes. In addition, the study presents the perspectives of ethanol supply on the post-COVID-19 and the importance of the Brazilian Biofuels Policy (RenovaBio) as a strategic tool for the biofuels supply and for the emission of carbon credits, with features adaptable to other countries.
