While some industries use “biobased carbon” and “biogenic carbon” interchangeably, they have a specific difference as defined in the ASTM D6866 standard:
“Biobased” means containing organic carbon of renewable origin like agricultural, plant, animal, fungi, microorganisms, marine, or forestry materials living in a natural environment in equilibrium with the atmosphere. Biobased carbon content is the amount of biobased carbon in the material or product as a percent of the Total Organic Carbon (TOC) in the product.
“Biogenic” means containing carbon (organic and inorganic) of renewable origin like agricultural, plant, animal, fungi, microorganisms, macroorganisms, marine, or forestry materials. Biogenic carbon content is the amount of biogenic carbon in the material or product as a percent of the Total Carbon (TC) in the product.
Industries | Term Used | Carbon Measured |
Biobased Products | Biobased | Total Organic Carbon |
Natural Ingredients, e.g. F&F | Biobased | Total Organic Carbon |
Biofuels | Biogenic | Total Carbon |
Fuel Gases | Biogenic | Total Carbon |
Waste-to-energy | Biogenic | Total Carbon |

SGS Beta routinely releases results in 7 business days or less. A priority service is available for clients requiring results in 4 business days or less. The lab consistently delivers results at these turnaround times by using an accelerator mass spectrometer (AMS).
ASTM D6866 testing by AMS is faster than ASTM D6866 testing by liquid scintillation counting (LSC). AMS is an advanced method compared to LSC; it is more accurate, precise and applicable to all types of samples regardless of color or viscosity.
The AMS method only requires a few milligrams per sample compared to the LSC method, thereby making sample transport more convenient for clients.

ASTM D6866 was developed at the request of the United States Department of Agriculture (USDA) to satisfy legislation requiring federal agencies to give preference in procurement to manufacturers using the greatest amount of biomass in their products (per the Farm Security and Rural Investment Act of 2002).
The standard was first published in 2004. There have been several versions released since then, with the correction factor periodically adjusted to make the standard more accurate relative to the current global atmospheric carbon measurement.
ASTM D6866 is applicable to laboratories working without exposure to artificial carbon-14. Details are found in the official ASTM D6866 page.
Formerly known as Beta Analytic, SGS Beta joined the American Society for Testing Materials (ASTM) Subcommittee D20.96 to help author ASTM D6866 in 2004. Today, ISO 17025-accredited SGS Beta is the world’s largest biobased/biogenic content testing laboratory.
SGS Beta is a natural level isotope laboratory.
