Abstract

This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids deals with the safety evaluation of the recycling process PRT (recoSTAR PET-FG) (EC register number RECYC050). The input of the process is washed and dried PET flakes originating from collected post-consumer PET bottles containing no more than 5% of PET from non-food consumer applications. Through the process, washed and dried PET flakes are heated and crystallised in a continuous first reactor under inert gas flow then heated in a second continuous reactor under inert gas flow before being extruded into pellets. After having examined the challenge test provided, the Panel concluded that the two steps, the drying and crystallisation (step 2) and the drying of the crystallised flakes (step 3) are the critical steps for the decontamination efficiency of the process. The operating parameters to control their performance are well defined and are the temperature, the gas flow and the residence time. The operating parameters of these steps in the process are at least as severe as those obtained from the challenge test. Under these conditions, it was demonstrated that the recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.1 μg/kg food. Therefore the Panel concluded that the recycled PET obtained from the process intended for the manufacture of materials and articles for contact with all types of foodstuffs for long term storage at room temperature, with or without hotfill is not considered of safety concern.
