Renewable fuels are those fuels that are produced from a renewable energy source. Examples are fuels made from biomass such as wood or crop waste, from oil extracted from plants, or from previously used materials (such as used cooking oil, or animal fats). In the case of renewable diesel, those renewable energy sources are carefully refined to become a high quality fuel component.
Esso Renewable Diesel R20 is made from waste oils such as used cooking oil. The blend component for the renewable fuels is not made from fatty acid methyl ester (FAME).
