Fatty Acid Methyl Esters (FAME) - ETIP Bioenergy
FAME is produced from vegetable oils, animal fats or waste cooking oils by transesterification. In the transesterification process a glyceride reacts with an alcohol in the presence of a catalyst, forming a mixture of fatty acids esters and an alcohol. …

Hydrogenated vegetable oil (HVO) - ETIP Bioenergy
www.etipbioenergy.euDiesel fuel standards, such as EN 590 and ASTM D 975, are met with high blending ratios of HVO. Biodiesel (FAME) standards are not applicable for HVO. HVO is today blended with fossil diesel and sold at fuel filling stations. HVO has also been approved to be used as an aviation (bio jet) fuel, based on ASTM D7566-14. In 2011,
