Large amounts of waste cooking oil (WCO) and waste scallop shells (WSS) are discharged from local restaurants. In this study, alkaline solid catalysts were manufactured from WSS via calcination and reused for repeated biodiesel production from WCO, with a free fatty acid content of 1.9%. The optimal calcination conditions were determined to be 750℃ for 3 h. The optimal reaction conditions for biodiesel production from WCO were 3.5 wt% of the solid catalyst relative to the WCO, 0.7 mL-methanol/g-WCO, 60℃, 5 h of reaction time, and 150 rpm. Under these optimal conditions, a biodiesel conversion of 90.2% was achieved. Among the various treatment methods for the reuse of solid catalysts, simple separation of the reaction mixture and filling of fresh WCO and methanol into the reactor containing the solid catalysts used in previous biodiesel production was the most effective. The alkaline solid catalysts were successfully reused for seven rounds of biodiesel production, maintaining > 85% of biodiesel conversion under the optimal reaction conditions.
