Agroindustrial aspects of Sweet Sorghum and Biomass for the production of energy and ethanol of first and second generation

Abstract

In recent years, due to the increasing pressures of society by the use of biofuels in the world, new technologies and/or processes have been developed, aiming at minimizing the use of gasoline in automotive vehicles, among them, ethanol-fueled engines or with additive gasoline. Currently, much of this biofuel is produced from industrial processing of corn (USA) and sugarcane (BRAZIL). However, only the use of these raw materials will not be sufficient to meet the demand estimated at 1.7 trillion liters by 2025. In this sense, research to study and make feasible the use of sorghum sorghum (Sorghum bicolor (L.) Moench.) as an economically promising raw material for the production of ethanol, which can be implemented in sugarcane renewal areas using the same industrial park of the sugar cane, are extremely essential. This technology has been developed in recent years. Although, there is still a lot of information to be answered for the sorghum crop in large areas, from genotype response to different production environments until the second generation of ethanol production. This research aims to evaluate the biometric parameters of two sorghum sorghum genotypes and one of sorghum biomass; Suitability of the must and the fermentation process using industrial yeasts (ethanol 1G); Characterization of the bagasse aiming the production of energy; Acid / enzymatic hydrolysis to produce 2G ethanol; Molecular identification of isolated and selected yeasts that have the ability to ferment pentoses and reproduce the results on a pilot scale, using the treatments that present the best performance in the first stages of project development. The results will be published in periodicals and technical-scientific events, contributing to the consolidation of sweet sorghum and biomass as raw material for the production of ethanol and energy.
