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 Coexpan Deutschland recycling process (EU register number RECYC0140), which is based on the EREMA Basic technology. 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 this technology, post-consumer washed and dried PET flakes are heated in a continuous reactor under vacuum before being extruded. Having examined the results of the challenge test provided, the Panel concluded that the continuous reactor step (step 2) is the critical step that determines the decontamination efficiency of the process. 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 0.15 μg/kg food, derived from the exposure scenario for toddlers. The Panel concluded that recycled PET obtained from the process is not of safety concern when the final thermoformed trays and containers manufactured with the recycled sheets and not used for packaging water contain up to 100% recycled post-consumer PET. Thermoformed trays 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(CEF小组)的这一科学意见涉及基于埃瑞玛基本技术的德国科埃斯潘回收工艺(欧盟注册号RECYC0140)的安全性评估。该工艺的输入材料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,其中来自非食品消费应用的PET含量不超过5%。在该技术中,消费后经洗涤和干燥的PET薄片在连续反应器中于真空下加热,然后进行挤出。在审查了所提供的挑战试验结果后,专家小组得出结论,连续反应器步骤(步骤2)是决定该工艺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,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根据幼儿暴露场景保守模拟得出的0.15μg/kg食品的迁移量。专家小组得出结论,当用回收片材制造且不用于包装水的最终热成型托盘和容器含有高达100%回收的消费后PET时,该工艺获得的回收PET不存在安全问题。热成型托盘不打算用于且不应在微波炉和传统烤箱中使用。
