Abstract

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Intco Malaysia (EU register number RECYC309), which uses the VACUNITE (EREMA basic and Polymetrix SSP V-leaN) technology. The input consists of hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes mainly originating from collected post-consumer PET containers, with no more than 5% PET from non-food consumer applications. The flakes are pre-decontaminated in the ■■■■■ at ■■■■■ under ■■■■■ (step 2), then extruded and pelletised. The ■■■■■ pellets are then ■■■■■ and submitted to solid-state polycondensation (SSP) at ■■■■■ under ■■■■■ and ■■■■■. Having examined the challenge tests provided, the Panel concluded that the step 2 (flake reactor) and steps 4 and 5 (preheating and SSP) are critical for determining the decontamination efficiency of the process. The operating parameters to control the performance are temperature, pressure and residence time for steps 2, 4 and 5 as well as the ■■■■■ for steps 4 and 5. It was demonstrated that this recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below the conservatively modelled migration of 0.1 μg/kg food. Therefore, the Panel concluded that the recycled PET obtained from this process is not of safety concern, when used at up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs, including drinking water, for long-term storage at room temperature or below, with or without hotfill. The final articles made of this recycled PET are not intended to be used in microwave and conventional ovens and such uses are not covered by this evaluation.
