Summary: The global trend towards net-zero carbon emissions from burning fuels in combustion engines highlights the alternative role of biodiesel. The manufacturing cost of biodiesel, determined by feedstock cost, hinders its development. Low-cost feedstocks with high acid content and water cannot be used on an industrial scale. However, through a supercritical transesterification reaction system, these feedstocks can be converted into biodiesel, which shows potential as a competitive alternative fuel to fossil diesel.
