Oil companies are legally obliged to sell an annually increasing percentage of biofuels of all fuel they sell for road transport. For vehicles with diesel engines, there are two biodiesel alternatives, called Fatty Acid Methyl Ester (FAME) and Hydrotreated Vegetable Oil (HVO). Both types can be made from vegetable or animal oils and fats or from residues such as used cooking oil, making them a renewable fuel and a sustainable alternative to fossil diesel.
FAME is mixed up to 7% in fossil diesel. In Europe, all diesel vehicles can run on 7% biodiesel. At the pump, this biodiesel is therefore referred to as B7. Most heavy transport engines for trucks and shipping, for example, are suitable for handling a higher proportion (B30).
HVO is a renewable diesel, which is chemically identical to fossil diesel. It can be mixed in any proportion.
