This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids deals with the safety evaluation of the recycling process Gneuss 1 (EU register No RECYC0143). The input is washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, containing no more than 5% of PET from non-food applications. They are extruded under vacuum into pellets or sheets. Having examined the challenge test provided, the Panel concluded that the decontamination in the extruder under vacuum degassing is the critical step for the decontamination efficiency of the process. The operating parameters to control its performance are well defined and are temperature, pressure, residence time, throughput rate, rotor speed and satellite screws speed. The operating parameters of this step are at least as severe as those obtained from the challenge test. It was demonstrated that this recycling process is able to ensure that the level of migration of potential unknown contaminants into food is below a conservatively modelled migration of 0.1 μg/kg food. Therefore, the recycled PET obtained from the process Gneuss 1 intended for the manufacture of articles made with up to 100% recycled post-consumer PET and intended for contact for long-term storage at room temperature with all types of foodstuffs is not considered of safety concern. Trays made of this recycled PET are not intended to be used, and should not be used, in microwave and conventional ovens.
欧洲食品安全局食品接触材料、酶、香料和加工助剂专家小组的这一科学意见涉及回收工艺Gneuss 1（欧盟登记号RECYC0143）的安全性评估。其输入物是经清洗和干燥的聚对苯二甲酸乙二酯（PET）薄片，源自收集的消费后PET容器，其中非食品用途的PET含量不超过5%。这些薄片在真空条件下被挤出制成颗粒或片材。在审查了所提供的挑战测试后，专家小组得出结论，在真空脱气的挤出机中的去污是该工艺去污效率的关键步骤。控制其性能的操作参数已明确界定，包括温度、压力、停留时间、产量、转子速度和卫星螺杆速度。该步骤的操作参数至少与从挑战测试中获得的参数一样严格。已证明该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0.1 μg/kg食品的迁移量。因此，通过Gneuss 1工艺获得的再生PET，用于制造由高达100%消费后再生PET制成的制品，并打算在室温下与所有类型的食品进行长期接触储存，不被认为存在安全问题。由这种再生PET制成的托盘不得且不应在微波炉和传统烤箱中使用。
