The duck and chicken eggshell wastes were applied as raw materials for the preparation of heterogeneous catalyst in biodiesel production. Prior to use, the calcium carbonate (CaCO3) content in the waste shell was converted to calcium oxide (CaO) by calcining at 600-900C for 4h. The physicochemical properties of the solid oxide catalyst were characterized by X-ray diffraction (XRD), X-ray fluorescence (XRF), scanning electron microscopy (SEM) and the Brunauer-Emmett-Teller (BET) method. The catalytic activity of the catalyst in transesterification of palm oil with methanol was evaluated, and the fuel properties of obtained biodiesel were measured. The effect of reaction time, reaction temperature, methanol/oil molar ratio, catalyst loading, and reusability of catalyst was also investigated. Eggshell waste is a bioresource for the production of heterogeneous base catalyst that can be successfully utilized for the synthesis of biodiesel with high purity.
