Biodiesel: Sources, production, emissions, and policies

Abstract

A major part of energy generated is being consumed by transport sector creating an imbalance in the atmosphere by releasing the emissions resulting in global warming which is the biggest threat to living beings and the environment. Therefore, it is importance and need of biodiesel as a replacement for diesel and other conventional fuels. The various sources of biodiesel production comprise of obtaining raw oil from the seeds and are converted to biodiesel through various techniques of transesterification that utilizes catalysts to increase the yield. The newly available techniques have been discussed with primarily focusing on the various catalysts that affect the yield keeping in view the policies related to curtail down the global warming.
