Composed of or derived from, in whole or in part, biological products derived from the biomass (including plant, animal, and marine or forestry materials).
Note: Lactic acids are obtained from the fermentation of natural products, such as corn or sugars, or from oil-based chemistry. Only the lactic acid-based polymers derived from natural sources are biobased.
