Abstract

The growing concerns over global warming and the finite nature of fossil fuel resources have spurred interest in biodiesel as promising alternative towards carbon-neutral economy. Substituting petro-diesel with biodiesel could trigger to a remarkable decline in environmental pollution. Amidst several customary processes, transesterification is ascertained to be a globally well-adopted cost-competent and scalable method of biodiesel manufacturing. Nevertheless, transesterification faces many challenges particularly with homogeneous catalysis, such as catalyst separation and formation of wastewater. Calcium oxide (CaO) as a heterogeneous catalysts have gained momentum of interest. However, it has still some bottlenecks in scaling-up.
