摘要

An Italian company based near Rome produces a large quantity of biodiesel. It is primarily produced from used frying oils sourced from Italy, France, Spain and Holland. In addition to biodiesel they also make distilled fatty acids, glycerin, and vegetable olein. For the most part these are byproducts of the biodiesel process. Biodiesel is produced through a transesterification reaction, a process in which a vegetable oil is reacted in excess of methyl alcohol in the presence of an alkaline catalyst. The products are sold throughout Europe.
