In Brazil, the addition of 2% of biodiesel to diesel began to be mandatory in 2008 and reached 14% in 2024, with a prediction of achieving 25% by 2030. This measure, encouraged by public policies, contributes to the decarbonization of the economy and the country’s energy transition, significantly impacting the global efforts against climate crises. This article presents a systematic review of the literature on the oxidative stability of biodiesel. It addresses aspects involving the activation energy of the abstraction of bis-allylic hydrogens from fatty esters, studied by proton nuclear magnetic resonance spectroscopy, up to the cleaning of storage and transport tanks, crucial to avoid points of corrosion which generate metallic ions that catalyze the oxidative processes. The article describes the reaction mechanisms and effectiveness of antioxidants, addressing the lack of studies on the potential for bioaccumulation and toxicity associated with combustion gases. It also discusses how natural antioxidants and agro-industrial residues can enhance the sustainability of continuous and large-scale use of this biofuel.
