What is the resin identification code (RIC) for isosorbide-based plastics?
See answerIn the context of circular economy, the ability to recycle packaging material is key.
Among all plastics materials, poly(ethylene terephthalate) has the highest recycling rate. Moreover, it can be recycled either via mechanical recycling or via chemical depolymerization to regenerate initial monomers.
PET modified with POLYSORB® isosorbide to a certain extent keeps their semi-crystalline properties. In that case, the material could be mechanically recycled in the PET stream. The properties of the resulting recycled material fulfill all tests described by EPBP up to 50% of modified PET. In addition, the material could be identified with the Recycling Identification Code (RIC) #1 based on the requirements of Standard ASTM D7611-D7611M*.
