en.Wedoany.com Reported - SK Chemicals' copolyester and PET products have received certification from RecyClass, a European recycling assessment body, confirming they can be recycled within PET recycling streams. The company announced on May 26 that its ECOTRIA CLARO series copolyesters and SKYPET series PET-based products have been recognized by RecyClass.
RecyClass is a non-profit, cross-industry initiative dedicated to advancing the circular economy for plastics in Europe. It certifies the recyclability of plastic materials through a structured framework based on assessment protocols and design guidelines. The Technology Approval (TA) obtained by SK Chemicals is a key benchmark under this framework, verifying whether a material can serve as a reliable feedstock in actual recycling processes without disrupting existing operations. Materials without verified compatibility could lead to process interruptions or quality degradation.
This certification provides authoritative validation of the value of SK Chemicals' diverse polyester product portfolio—ranging from copolyesters to PET, and from recycled to virgin materials—as recycling feedstock. The industry view holds that materials need to both contain recycled content and be recyclable themselves to build a sustainable circular structure. SK Chemicals CEO Ahn Jae-hyun stated that this is official recognition of the circularity of their materials as feedstock, and the company will continue to accumulate recycling technology expertise and expand cooperation with European customers and stakeholders.
Among the seven products assessed, five copolyester products—ECOTRIA CLARO 100, ECOTRIA CLARO 200, ECOTRIA CLARO 300, ECOTRIA CLARO 100 CR50N, and ECOTRIA CLARO 200 CR50N—received the Full Compatible rating, allowing them to be co-recycled without restrictions in PET recycling processes. Two PET products, SKYPET BR and SKYPET BR-V, received the Limited Compatible rating, meaning they can be recycled under specific process conditions. Last year, PET bottles made from SK Chemicals' circular recycled PET, SKYPET CR, received the highest A-grade rating in a RecyClass Letter of Compatibility (LoC), with those bottles utilizing SKYPET CR BB and SKYPET CR BL.
