Eastman received RecyClass Recyclability Approvals for eight copolyester resins and their equivalent Renew grades, containing recycled content. RecyClass is a non-profit, cross-industry initiative promoting recyclability, transparency and traceability abot plastics in Europe.
Six copolyesters, also known as speciality PET, were classified as fully compatible with the state-of-the-art recycling processes for PET bottles in Europe. This includes: Cristal™ EN076; Cristal™ One; Cristal™ One Pro; Cristal™ One IM812; Cristal™ One E and Cristal™ One E Lux.
Additionally, two of Eastman’s resins, Cristal™ EN067 and Cristal™ EN059 were recognised as limited compatible.
The approval follows independent testing conducted by PTI-Europe and Plastics Forming Enterprises (PFE), following an adapted version of the Recyclability Evaluation Protocol for PET bottles.
The approval means the copolyesters do not interfere with the established recycling processes in Europe, making them an ideal solution for brand owners aiming at bringing circular solution to their non-beverage packaging applications such as skincare jars, bottles, caps, and colour cosmetics.
“With their lower crystallisation rates compared to standard PET, these resins offer durability, high transparency, and lustre in final products,” explains Eastman in a media statement.
A copolyester is a copolymer synthesized by modification of polyesters, which are combinations of diacids and diols. For example, by introducing isophthalic acid (IPA), or cyclohexane dimethanol (CHDM) to the polyester polyethylene terephthalate (PET). Copolyesters retain their strength, clarity, and other mechanical properties even when exposed to a variety of chemicals that typically affect other materials. Eastman is one of the main global manufacturers and suppliers of copolyester resins.
