The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Coca-Cola HBC (EU register number RECYC285), which uses the NGR technology. The input is 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 dried (step 2), melted in an extruder (step 3) and decontaminated during a melt-state polycondensation step ■■■■■ (step 4). In step 5, the material is granulated. Having examined the challenge test provided, the Panel concluded that the melt-state polycondensation (step 4) is critical in determining the decontamination efficiency of the process. The operating parameters to control the performance of the critical step are the pressure, the temperature, the residence time (depending on the mass and throughput of the melt) and the characteristics of the reactor. 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, 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、酶和加工助剂专家委员会（CEP）评估了采用NGR技术的可口可乐HBC回收工艺（欧盟注册号RECYC285）的安全性。其输入物是经过清洗和干燥的聚对苯二甲酸乙二酯（PET）薄片，主要来源于收集的消费后PET容器，非食品消费用途的PET含量不超过5%。这些薄片经过干燥（步骤2）、在挤出机中熔化（步骤3），并在熔融态缩聚步骤■■■■■（步骤4）中进行去污处理。在步骤5中，材料被造粒。在审查了所提供的挑战试验后，专家委员会得出结论，熔融态缩聚（步骤4）对确定该工艺的去污效率至关重要。控制关键步骤性能的操作参数包括压力、温度、停留时间（取决于熔体的质量和产量）以及反应器的特性。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，专家委员会得出结论，当将此工艺获得的再生PET以高达100%的比例用于制造与包括饮用水在内的所有类型食品接触的材料和制品，用于在室温下长期储存（无论是否热灌装）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。
