Avaliação da produção de bioetanol a partir de resíduos agroindustriais utilizando processos de fermentação: um estudo de prospeção tecnológica

Abstract

The use of agro-industrial residues as a source of renewable energy emerges as a solution of two major issues of current environmental impact: amount of waste generated in agroindustry and replacement of energy derived from petroleum. this scenario triggered several researches in recent years with the aim of developing processes sustainable ways of converting biomass into value-added products such as bioethanol. By having In view of the above, the present work aimed to carry out a study of technological prospecting using the Thomsom Innovation platform to collect information of patents regarding the production of ethanol using a fermentation process from agro-industrial waste. The information extracted allows us to state that South Korea (32) was the country with the highest number of patent documents. From 2003 onwards, there has been a greater application for patent numbers, (1 to 16). More than (50) types of biomass were found residues that have been used to obtain second-generation ethanol. the hydrolysis enzymatic, was evidenced in (32%) of the works analyzed. The most used CIP in documents analyzed was from C12P, referring to fermentation processes or processes that use enzymes to synthesize compounds. The industrial sector stands out as the largest requester of filed patents. This study showed that there is a wide variety of biomass residues that can be applied to obtain bioethanol through processes of fermentation being, therefore, a viable alternative for the substitution of fossil energy and a option that adds value to the agribusiness sector in addition to minimizing the environmental impact.
