Biobased carbon content according to ASTM D6866

The biobased carbon content of solid or liquid materials indicates how much of the total organic carbon originates from renewable resources. The analysis includes the removal of inorganic carbon before testing, where necessary. The method is based on analyzing different carbon isotopes present in the sample using accelerator mass spectrometry (AMS). Biobased carbon content determination according to ASTM D6866 does not reveal how much of the sample's total weight originates from renewable sources. This can be estimated, however, by combining data on biobased carbon content with information on the total carbon content of the product.
