Several components have been evaluated via independent testing facilities to investigate the behaviour of common packaging technologies during the sorting and recycling processes. These tests were carried out according to standardised testing methods, as described in the RecyClass Recyclability Evaluation Protocols2.
Following the alignment with the Associations of Plastics Recyclers (APR)3, the RecyClass Recyclability Evaluation Protocols have been updated to improve the processing conditions and characterization of the materials. New testing procedures for PET bottles, and adhesives applied on PET bottles were also developed4.
Since sorting is the foundation for high-quality recycling, RecyClass carried out trials on non-PE decorations on HDPE bottles, with extensive coverage as well as on PP and HDPE rigid rolling packaging, to further clarify the sorting performances of different plastics5.
Notable additions to the Guidelines include a more detailed classification of ink binders and AlOx coatings with PVOH primer in PO films, as well as of PU-based materials for laminating adhesives in PP flexible packaging.
