Scope
This document specifies the calculation method for determining the biobased carbon content in monomers, polymers, and plastic materials and products, which is based on the determination of 14C content.
This document is applicable to plastic products, plastic materials, polymer resins, monomers, or additives that contain biobased or fossil-based components.
Determining the biobased content of plastic products helps assess their impact on the environment.
