Diester

Biofuel obtained by converting plant or animal oils, such as rapeseed, sunflower or used cooking oil. Also referred to as biodiesel. It can be used in existing diesel engines when blended into conventional diesel in concentrations of 7 to 30%. In France, diester refers specifically to fatty acid methyl esters (FAME), sometimes also known as vegetable oil methyl esters (VOME), biofuel obtained by the reaction of vegetable oils and methanol.
