The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process PT Veolia Indonesia (EU register number RECYC289), which uses the Polymetrix technology. The input material is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, e.g. bottles, including no more than 5% PET from non-food consumer applications. The flakes are extruded to pellets, crystallised and subsequently decontaminated in a solid-state polycondensation (SSP) reactor under high temperature and gas flow. Having examined the challenge tests provided, the Panel concluded that the fourth step, the decontamination in the SSP reactor, is critical in determining the decontamination efficiency of the process. The operating parameters to control the performance of this critical step are temperature, gas velocity and residence time. It was demonstrated that this recycling process is able to ensure a level of migration of potential unknown contaminants into food 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 considered to be 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 or 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)评估了采用波利美特rix技术的印度尼西亚PT威立雅回收工艺(欧盟登记号RECYC289)的安全性。输入材料是经过热洗和干燥的聚对苯二甲酸乙二酯(PET)片材,其源自收集的消费后PET容器,如瓶子,其中非食品消费应用的PET含量不超过5%。这些片材被挤出成颗粒,进行结晶,随后在高温和气流下于固态缩聚(SSP)反应器中进行去污处理。在审查了所提供的挑战测试后,专家委员会得出结论,第四步,即在SSP反应器中的去污处理,对于确定该工艺的去污效率至关重要。控制这一关键步骤性能的操作参数是温度、气体流速和停留时间。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,专家委员会得出结论,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,并在室温下长期储存(有无热灌装)时,通过该工艺获得的再生PET被认为不存在安全问题。由这种再生PET制成的最终制品不打算用于微波炉或传统烤箱,本评估不涵盖此类用途。
