Biogenic Testing of Biofuels

Measuring % Biogenic Carbon versus % Fossil Carbon in any biofuel blend, lubricants, and liquids with high petrochemical content

Biofuels can be derived from biomass (e.g. bio-ethanol) or fossil resources (e.g. petroleum). Biogenic carbon testing uses Carbon-14 technology to determine the biomass-based or biogenic fraction vs. fossil fraction of biofuels and other products. For example, bio-ethanol and synthetic fossil-derived ethanol are chemically indistinguishable but Carbon-14 testing will accurately distinguish the two. 

Since carbon-14 is only present in living or recently expired material, Carbon-14 testing using Accelerator Mass Spectrometry (AMS) is the most effective method to determine the amount of biogenic carbon versus petroleum-derived carbon in biofuel blends.

What does “biogenic” mean?

The ASTM D6866-24 analytical standard defines “biogenic” as containing carbon (organic and inorganic) of renewable origin like agricultural, plant, animal, fungi, microorganisms, macroorganisms, marine, or forestry materials.

Biogenic Testing Reporting Standards

  • ASTM D6866 – Biogenic content percentage is expressed as a fraction of total carbon of the biofuel, lubricant, or liquids with high petrochemical content
  • EN 16640 – Result is expressed as % biobased carbon as a fraction of total carbon (applicable ONLY to lubricants and liquids with high petrochemical content)
