Inovações sustentáveis em biocombustíveis no Brasil e a substituição dos combustíveis fósseis: revisão sistemática da literatura

Abstract

In view of the growing global concern with the increase in terrestrial temperature, due to the unrestrained emission of greenhouse gases, solutions are sought to minimize the environmental and social damage caused by them. One of the best options currently available are the biofuels, as they are renewable and sustainable, in addition to having several applications. In this context, the present work aimed to systematically analyze the published studies on new biofuels, time of energy transitions, factors that influence the development and diffusion of technologies capable of replacing fossil fuels, advantages and disadvantages of each application, in addition to the main trends and gaps in the area in Brazil. For the survey of articles, searches were carried out in the Science Direct database, using the keywords: “biofuel AND sustainable innovation AND Brazil AND multi-level” and filtering by category review articles and research articles. Thus, one hundred and twenty-six articles were obtained, which were analyzed considering objectives, methodology, main results, conclusions, links with sustainable innovation and year of publication. From the results obtained, there is a large focus of research on traditional renewable energy sources, such as ethanol, in addition to the fact that most studies are of the qualitative type. Still, there is a significant increase in the number of publications after 2015, mainly justified by the creation of the Sustainable Development Goals and RenovaBio. Thus, the importance of obtaining new sources and processes for biofuels is highlighted and, in this way, achieving a development that encompasses environmental, social and financial benefits for all parties involved, as well as for the population in general, since, there is still a large research gap in the area and more incentives and investments are needed in research, development, implementation and dissemination of biofuels.
