The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Veolia Huafei Polymer Technology (Zhejiang) (EU register numberRECYC292), which uses the VACUNITE (EREMA basic and Polymetrix SSP V-leaN) technology. The input consists of 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 pre-decontaminated in the ■■■■■ at ■■■■■ under ■■■■■ (step 2) before being extruded, pelletised and ■■■■■ (step 3). The ■■■■■ pellets are then ■■■■■ (step 4) and submitted to solid-state polycondensation (SSP) (step 5) at ■■■■■ and under ■■■■■ and ■■■■■. Having examined the challenge tests provided, the Panel concluded that step 2 as well as steps 4 and 5 are critical for determining the decontamination efficiency of the process. The operating parameters to control the performance are temperature, pressure and residence time for steps 2, 4 and 5 as well as the ■■■■■ for steps 4 and 5. 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 or below, with or without hotfill. 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）评估了威立雅华菲高分子科技（浙江）公司（欧盟注册号：RECYC292）采用VACUNITE（埃瑞玛基础型和Polymetrix SSP V-leaN）技术的回收工艺的安全性。其输入材料为经过热碱洗和干燥处理的聚对苯二甲酸乙二酯（PET）片材，主要来源于收集的消费后PET容器，非食品消费应用的PET含量不超过5%。这些片材在■■■■■中于■■■■■、在■■■■■条件下进行预去污（步骤2），然后进行挤出、造粒和■■■■■（步骤3）。接着，■■■■■颗粒进行■■■■■（步骤4），并在■■■■■、在■■■■■和■■■■■条件下进行固态缩聚（SSP）（步骤5）。在审查了所提供的挑战试验后，小组得出结论，步骤2以及步骤4和5对于确定该工艺的去污效率至关重要。控制性能的操作参数包括步骤2、4和5的温度、压力和停留时间，以及步骤4和5的■■■■■。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，小组得出结论，当以高达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，并在室温或更低温度下长期储存（无论是否热灌装）时，通过该工艺获得的再生PET不存在安全问题。由这种再生PET制成的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。
