The optimal calcination for the catalyst synthesis was achieved at 500 °C for 4 h. Various analytical techniques were employed to investigate the properties of the developed catalyst. The results indicate that the catalyst primarily consists of mesoporous particles abundant in potassium, with medium to strong basic sites, which are crucial for its catalytic function. WCO underwent pretreatment with H<sub>2</sub>SO<sub>4</sub> before being converted to biodiesel. Optimum conditions for the biodiesel production were a methanol-to-WCO molar ratio of 9.87, 1.00 wt% catalyst dosage, 3.03 min reaction time, 450 rpm stirring speed, and 600 W microwave power, yielding 98.20 ± 0.81 wt% biodiesel. The low specific energy consumption value of 0.91 kWh/kg and specific CO<sub>2</sub> emission of 0.73 kg/kg of biodiesel suggest the effective utilization of microwave energy in driving the transesterification reaction and in promoting a reduction in carbon footprint, respectively. The synthesized catalyst remained effective up to the 5th production cycle and the biodiesel produced met established specifications.

Key to this mechanism is the H-assisted CO<sub>2</sub> dissociation pathway, supported by computational analysis. The pathway involves sequential reactions starting from CO<sub>2</sub> adsorption on catalyst sites, followed by successive transformations leading to the formation of hydrocarbon building blocks.
