WebOct 29, 2024 · Since biofuels are mostly processed from photosynthetic plants containing the radioactive isotope carbon-14, the analysis can accurately distinguish between biogenic and fossil fraction of fuels. 4 Carbon-14 testing can prove a certain percentage of biogenic or renewable carbon content within a blend. Carbon-14 analysis is frequently used to ... WebBiobased content is expressed as a percentage. New organic carbon is derived from plants and other renewable agricultural materials. Total organic carbon consists of new organic carbon and old organic carbon (which originates from petroleum). The presence of new organic carbon is an important attribute in a product's sustainability footprint.
