The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Poly Recycling (EU register number RECYC307), which uses the Vacurema Prime technology. The input is 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 heated in a batch reactor (Step 2) under vacuum and then treated at higher temperature in a continuous reactor (Step 3) under vacuum before being extruded into pellets. Having examined the challenge test provided, the Panel concluded that Steps 2 and 3 are critical in determining the decontamination efficiency of the process. The operating parameters to control the performance of these steps are temperature, pressure and residence time. 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, soft drinks, juices, tea, milk, oil, alcoholic beverages and other food products, 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.
欧洲食品安全局食品接触材料、酶和加工助剂小组（CEP）评估了采用Vacurema Prime技术的Poly Recycling（欧盟注册号RECYC307）回收工艺的安全性。其输入物是经过热碱洗和干燥处理的聚对苯二甲酸乙二酯（PET）薄片，主要源自收集的消费后PET容器，其中非食品消费应用的PET含量不超过5%。这些薄片先在间歇式反应器中（步骤2）于真空条件下加热，然后在连续式反应器中（步骤3）于真空条件下在更高温度下处理，之后再被挤出制成颗粒。在审查了所提供的挑战试验后，该小组得出结论，步骤2和步骤3对于确定该工艺的去污效率至关重要。控制这些步骤性能的操作参数是温度、压力和停留时间。结果表明，这种回收工艺能够确保潜在未知污染物向食品中的迁移水平低于保守模拟的0.1μg/kg食品的迁移量。因此，该小组得出结论，当这种工艺获得的回收PET以高达100%的比例用于制造与所有类型食品（包括饮用水、软饮料、果汁、茶、牛奶、油、酒精饮料及其他食品）接触的材料和制品，并在室温或更低温度下长期储存（有无热灌装均可）时，不存在安全问题。由这种回收PET制成的最终制品不打算用于微波炉和传统烤箱，本评估不涵盖此类用途。
