dc.description.abstractThe EFSA Panel on Food Contact Materials (FCM) assessed the safety of the recycling process Diamat SC (EU register number RECYC334). The input is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes mainly originating from collected postā€consumer PET containers, with no more than 5% PET from nonā€food consumer applications. The flakes are crystallised (step 2), dried (step 3) and extruded into sheets (step 4). Having examined the challenge test provided, the Panel concluded that the crystallisation, drying and extrusion steps (steps 2ā€“4) are critical in determining the decontamination efficiency of the process. The operating parameters to control the efficiency of the process are the temperature and the residence time for all steps (steps 2ā€“4), the air flow rate for step 3, the pressure and the characteristics of the extruder (step 4). It was demonstrated that this recycling process ensures that the level of migration of potential unknown contaminants into food is below the conservatively modelled migration of 0.0481 or 0.0962 Ī¼g/kg food, depending on the molar mass of a contaminant substance. 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 longā€term storage at room temperature or below, with or without hotā€fill. 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.eng
