1. Rationale
When ASTM adopted resin identification codes from SPI, it was the intent to make the adoption a means to allow for revisions to include resins in commercial use that werent anticipated when SPI established the original code system in the 1988. Since SPIs original adoption, several new resins have been placed in commercial use. Clearly and distinctly identifying these new resins through the now adopted ASTM D7611 code system will help consumers, brand-owners, retailers, waste collectors, municipal recovery facilities and reclaimers identify parts made from the resin and help to facilitate the desired recycling of such parts. This work item relates specifically to establishing a new resin identification code for PLA which is a renewable-resource based resin that is in commercial use in packaging applications. There is significant interest in recovering PLA for ultimate recycling and a unique resin identification code would help facilitate recovery.
