Summary

In addition to scientific problems posed by producing standard bio-diesel fuel from refuse waste material is technical merits and social reasons make it actual and needs for credible answers. In processing refuse feedstock the obstacle consists mainly in dealing with the free fatty acids that must be esterified into bio-diesel fuel component. In the present article a new technique is explored by using non-polar solvent medium, results of esterification reactions are reported. The faster kinetics and controlled and selective separation makes that the loss of valuable materials is reduced and the overall process is made to output reliable quality of biodiesel in smaller plants at improved efficiency, in converting secondary raw material.
