Biodiesel production can be made more sustainable by utilizing non-edible feedstock and heterogeneous catalysts, thus ensuring clean and affordable energy in conformity with the sustainable development goal (SDG 7). Herein, a reusable mixed metal (Ca–Mg) oxide-laden montmorillonite K10 (CaO–MgO@MK10) was developed by coprecipitation-impregnation method at different Ca2+/Mg2+ molar ratios followed by calcination at 700 °C for 4 h to ensure the Ca–Mg oxide deposition on MK10 surface for biodiesel synthesis via methanolysis of Jatropha curcas oil (JCO). The evaluation of the catalysts’ physicochemical properties and activity using various analytical methods and catalytic tests showed that the CaO–MgO@MK10 composite prepared at a 1.5:1 Ca2+/Mg2+ molar ratio (CaO–[email protected]:1) exhibited best catalytic activity for transesterification of JCO, ascribing to high basicity (15.0 < H_<18.4), large surface area (93.0 m2 g− 1), mesoporous structure and well dispersed Ca–Mg oxides on MK10 support. Optimization of methanolysis of JCO with a CaO–[email protected]:1 catalyst using Taguchi method determined optimum conditions (CH3OH/JCO ratio of 12:1, methanolysis temperature of 60 °C, catalyst concentration of 3 wt% and reaction duration of 3 h), under which the maximum biodiesel yield of 97.2 $$\:\pm\:0.17$$ % was achieved. The FAME content in the optimal biodiesel sample was 97.85 wt%, according to GC-MS analysis, exceeding the EN 14,214 biodiesel standard of 96.5 wt%. Moreover, CaO–[email protected]:1 was proven to be stable after being reused for 7 times with a minimal leaching of < 15%, indicating its promising industrial application potential.
