Biofuel is a form of renewable energy derived from a wide range of biomass-based products. There are currently two main forms: bioethanol and Fatty Acid Methyl Ester (FAME). The FAME is produced by extracting vegetable oil from various plants; such as switchgrass, and then esterifying it.
The FAME is blended with gasoline and diesel to produce biofuels, which can be used in unmodified engines.
In November 2020, the independent and accredited laboratory SGS analyzed a sample of Biofuel (pure bioheating oil) treated with the XBEE Enzyme Fuel Technology. The analysis demonstrated that such fuel, also known as FAME or B100, remains in compliance with the EN 14214 standard.
