Utilization of sea food waste as heterogeneous catalyst in transesterification reaction to produce biodiesel.

Transesterification reaction reacts vegetable or animal oil and alcohol as reactants with the support of a catalyst. This study produced biodiesel through a transesterification reaction between used cooking oil and alcohols with CaO heterogeneous catalyst from Anadara granosa. CaO compound was synthesized via temperature varying calcination process at 700°C, 800°C, and 900°C for 6 hours. Transesterification reaction was conducted at temperatures ranging from 55°C to 65°C and molar ratios of oil and methanol 1:12, 1:15, and 1:18. The process took place for 3 hours with the presence of a 3% m/m catalyst. The physical and chemical properties of synthesized biodiesel were in accordance with SNI standards. The highest yield of produced biodiesel was accomplished at 31.02% with 1:15 oil to methanol ratio and 60°C and 800°C of transesterification and calcination temperatures respectively.
