The depletion of rock oil supplies, environmental concerns, rising demand for petro-diesel, supply instability, and rising rock oil prices have prompted a desire for alternate fuels. Biodiesel is the most versatile fuel for conventional diesel engines. In our efforts to overcome the limitations of homogeneous catalysis, we prepared a heterogeneous low cost C3N4-CaO catalyst created by exploitation waste egg shells and FFA from soya bean oil is employed as a feedstock. Catalytic performance was assessed with the transesterification of FFA of Soya-bin oil with n-butanol. CaO was found to be the best catalyst with 68% conversion. The catalyst was also found to be active when recycled and reused for two runs without loss of catalytic activity.
