The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of the recycling process Bangladesh Petrochemical Company (EU register number RECYC246), which uses the Vacurema Prime technology. The input material is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, including no more than 5% PET from non-food applications. The flakes are heated in a batch reactor (step 2) ■■■■■ and then heated in a continuous reactor (step 3) ■■■■■ before being extruded into pellets. Having examined the challenge test provided, the Panel concluded that step 2 and step 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. The Panel concluded 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 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 for long-term storage at room temperature, 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小组）评估了采用Vacurema Prime技术的孟加拉国石油化学公司（欧盟注册号RECYC246）回收工艺的安全性。输入材料是经过热碱洗和干燥的聚对苯二甲酸乙二酯（PET）薄片，其来源于收集的消费后PET容器，其中非食品用途的PET含量不超过5%。这些薄片先在间歇式反应器中加热（步骤2）■■■■■，然后在连续式反应器中加热（步骤3）■■■■■，之后被挤出成粒料。在审查了所提供的挑战性试验后，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。小组得出结论，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，当这种工艺获得的再生PET以高达100%的比例用于制造与所有类型食品在室温下长期储存（无论是否热灌装）接触的材料和制品时，不存在安全问题。由这种再生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。
