On March 2, 2016 the European Food Safety Authority’s (EFSA) Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) published four scientific opinions on the post-consumer polyethylene terephthalate (PET) recycling processes ‘Coopbox’, ‘Ecoiberia’, ‘ANL’, and ‘Pramia Plastic Oy’, respectively. Processes ‘Coopbox’, ‘Ecoiberia’, and ‘ANL’ are based on the Starlinger Decon technology; process ‘Pramia Plastic Oy’ is based on the Starlinger IV+® technology. All four processes use washed and dried PET flakes from post-consumer PET containers containing no more than 5% PET from non-food applications. Challenge tests showed that the employed decontamination technologies can ensure that migration of potential unknown contaminants into food does not exceed 0.1 µg/kg food. Therefore, the CEF Panel concluded that recycled PET derived from all four processes is safe for use in materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill. Trays made of recycled PET from processes ‘Coopbox’, ‘Ecoiberia’, and ‘ANL’ should not be used in microwave and conventional ovens.
