This part of ISO 16620 specifies the general principles and the calculation methods for determining the
amount of biobased content in plastic products. These calculation methods are based on the carbon
mass or mass of each constituent present in the plastic products.
This part of ISO 16620 is applicable to plastic products and plastic materials, polymer resins, monomers,
or additives, which are made from biobased or fossil-based constituents.
Knowing the biobased content of plastic products is useful when evaluating their environmental impact.
