A hydroxyapatite (HAp) catalyst support from poultry's bones was derived and then modified with MgO/K2CO3 to generate a heterogeneous catalyst to produce biodiesel from a non-edible Moringa oleifera oil. The catalyst properties were analyzed with SEM, EDX-Map, XRD, FTIR, and N2 adsorption–desorption. A design of experiments by response surface methodology (RSM) via central composite design (CCD) including catalyst loading (1–5 wt%), temperature (40–80 °C), reaction time (50–250 min), and methanol to oil ratio (0.346–0.81 w/w) optimized the biodiesel yield. The P-value and F-value of the model proposed were 677.129 and <0.0001, respectively, thus the predictive model can identify the operating conditions that maximize biodiesel yield (99.3%). These conditions were catalyst loading of 4 wt%, reaction time of 200 min, methanol to oil weight ratio of 0.69, at 70 °C. The environmental performance (E-factor) was obtained 0.98, which indicates low waste generated from the process. The reusability of the catalyst was evaluated in 9 consecutive runs. The catalyst lost up to 40% of its activity, depending on the recovery method. The produced biodiesel complies with EN14214 and ASTM D6751 standards. Therefore, this investigation showed that MgO/K2CO3 can be used as a potential heterogeneous catalyst to produce biodiesel from non-edible Moringa oleifera oil.
