This study introduces an innovative approach to sustainable biodiesel production using mussel shell-derived calcium oxide (CaO) as a catalyst for converting Jatropha curcas oil into biodiesel. By repurposing waste mussel shells, the research aims to provide an eco-friendly and cost-effective solution for environmentally responsible biodiesel production, aligning with global standards. The study involves characterizing the catalyst, optimizing reaction conditions, and achieving a remarkable 99.36% Fatty Acid Methyl Ester (FAME) yield, marking a significant step toward cleaner and more economically viable energy sources. Biodiesel, recognized for its lower emissions, is produced through transesterification using mussel shell-derived CaO as a sustainable catalyst. This research contributes to cleaner and economically viable energy sources, emphasizing the importance of sustainable energy solutions and responsible catalytic processes. This research bridges the gap between waste management, catalyst development, and sustainable energy production, contributing to the ongoing global shift towards cleaner and more economically viable energy sources.

“…12,[19][20][21][22][23] Various factors, such as temperature, methanol-oil molar ratio, amount of catalyst, pressure, reaction time, amount of water, FFA and co-solvents, have been studied for process optimization. 24,25 The FFA and water content can compromise biodiesel quality as the basic catalyst used in transesterification can generate soaps by the parallel saponification reaction. 8,26 To avoid the saponification reaction, the concentrations of FFA and water must be below 5% and 1%, respectively.…”

SrO has attracted attention for its use as a heterogeneous catalyst in producing biodiesel from transesterification owing to its high alkaline character and low solubility in methanol. In studies conducted in this decade, reaction conditions such as the methanol–oil molar ratio, reaction time, catalyst loading and temperature have been optimized in these systems. Furthermore, several works have been carried out to improve the physicochemical properties and increase the leaching resistance of this material. Thus, the new trends in using SrO in transesterification reactions are that this oxide should be supported or combined with Al2O3, TiO2, ZrO2, or Fe2O3, CaO, metal–organic frameworks, zeolites or La2O3. It has been observed that strontium can form mixed crystalline phases with these oxides by increasing the (M2+O2−) pairs and Lewis basicity of the oxygens, resulting in increased basicity and catalytic activity. Moreover, the transition metal oxides may provide Lewis acidity. Hence, these strontium‐containing catalytic systems have demonstrated a bifunctionality that can perform esterification and transesterification reactions at the same time. In addition, the combination of these oxides decreases the leaching of the catalyst. Other materials such as metal–organic frameworks, zeolites, and La2O3 have been studied as SrO supports, showing that they can be used in oil transesterification reactions.
