Biofuels in Brazilian aviation: Current scenario and prospects

The aviation industry accounts for 2% of all carbon dioxide released into the atmosphere. Based on that, various companies and agencies have developed a growing interest in developing alternative fuels for aviation in recent decades. Few studies related to the production and use of biofuels in aviation can be found in the literature, and some of them are even contradictory. Thus, this study aims at discussing the current scenario and prospects for the use of aviation biofuels in Brazil, coming to the conclusion that despite Brazil having vast farmland and several oilseed crops with potential for biofuel production, the high demand caused by the current use of biodiesel added to diesel oil in the Brazilian vehicle fleet compromises the use of these materials with other energy purposes.
