Eggshells were used as raw material to generate CaO as a solid heterogeneous catalyst for biodiesel production via ethanolysis of palm oil. The catalysts derived from eggshells at 800°C provided high activity which high yield of fatty acid ethyl ester (FAEE) of 97.53% was obtained from the optimum conditions. After treatment process, the high quality of biodiesel product was obtained and passed all significant fuel properties of the ASTM and EN standards. These results could be suggested that waste eggshells showed good potential to be used as catalyst for biodiesel production with ethanol reagent.
