This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety assessment of the EREMA recycling process (the EREMA Multi-Purpose Reactor (MPR), EREMA Basic and EREMA Advanced technologies), with EU register number RECYC0134. The input to this process is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, containing no more than 5% PET from non-food consumer applications. In the MPR technology, post-consumer washed and dried PET flakes are heated in a continuous reactor under vacuum. The EREMA MPR decontamination technology can be combined with an extrusion line for pellets or sheet (EREMA Basic) or with an additional reactor (EREMA Advanced). The decontamination efficiency of the main continuous reactor (EREMA MPR technology) was determined by the challenge test. The Panel noted that this reactor is the critical step that determines the decontamination efficiency of these three EREMA technologies. The operating parameters controlling its performance are well defined and are temperature, pressure and residence time. It was demonstrated that, depending on the operating conditions, the recycling process under evaluation 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, derived from the exposure scenario for infants, and 0.15 μg/kg food, derived from the exposure scenario for toddlers, when recycled PET is used at up to 100%. The Panel concluded that recycled PET obtained from the process is not of safety concern when used to manufacture articles intended for food contact applications if it is produced in compliance with the conditions and the percentage of recycled PET added to virgin PET specified in this opinion.
欧洲食品安全局食品接触材料、酶、香料和加工助剂专家委员会（CEF 委员会）的这一科学意见涉及 EREMA 回收工艺（EREMA 多功能反应器（MPR）、EREMA 基础技术和 EREMA 先进技术）的安全性评估，其欧盟注册号为 RECYC0134。该工艺的输入物是来自收集的消费后聚对苯二甲酸乙二酯（PET）容器的热洗和干燥 PET 薄片，其中非食品消费应用的 PET 含量不超过 5%。在 MPR 技术中，消费后洗涤和干燥的 PET 薄片在连续反应器中于真空下加热。EREMA MPR 去污技术可与用于生产颗粒或片材的挤出生产线（EREMA 基础技术）或与额外的反应器（EREMA 先进技术）相结合。主要连续反应器（EREMA MPR 技术）的去污效率通过挑战性试验确定。委员会指出，该反应器是决定这三种 EREMA 技术去污效率的关键步骤。控制其性能的操作参数明确，为温度、压力和停留时间。结果表明，根据操作条件，当回收的 PET 使用比例高达 100%时，所评估的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基于婴儿暴露场景保守模拟得出的 0.1μg/kg 食品以及基于幼儿暴露场景保守模拟得出的 0.15μg/kg 食品。委员会得出结论，如果按照本意见规定的条件生产且回收的 PET 添加到原始 PET 中的比例符合要求，那么该工艺获得的回收 PET 用于制造食品接触用制品时不存在安全问题。
