The current world hegemonic energy model is mostly based on the burning of fossil fuels. The heavy reliance on oil and natural gas for the generation of energy as well as the pollution resulting from the burning of such fossil fuels is a global concern. In the midst of a scenario where more and more energy is spent, thinking about alternatives for generating this energy has already become a necessity. Biofuels have proven to be a good way to replace or reduce dependence on the use of non-renewable sources. The ANP regulates any and all fuels in Brazil, whether from renewable or non-renewable sources. Soybean biodiesel was produced on a laboratory scale by means of a transesterification reaction. An analysis of the exergy of the process and physical-chemical characterization of the biodiesel produced was carried out and a brief discussion on the following parameters: upper and lower calorific value, water content, specific mass at 20 ° C, kinematic viscosity at 40 ° C, index of acidity and oxidative stability, verifying the adequacy to the parameters of ANP Resolution 45/2014 and that served as basis for the discussion on the quality of biodiesel as fuel. According to the analysis of the exergy and the physicochemical characterization made, despite the lack of water content and oxidative stability, soybean biodiesel proved to be a good alternative to the indispensable use of fuels.
