USDA Certified Bio-based Products: The United States Department of Agriculture gives “USDA BioPreferred” certification to products derived from plants and other renewable agricultural, marine, and forestry materials which give an alternative to conventional petroleum derived products. Our 1.74 has been certified to be USDA Biomass 82%. This means the ratio of fossil fuel-derived carbon and biomass-derived ingredients is 18 to 82, respectively, when tested by ASTM-D6866-12, the standard test for determining bio-based content of solid, liquid, and gaseous samples using carbon-14 radiocarbon analysis.
