- Safety assessment of the process ‘RecyPET Hungária’, based on RecyPET Hungária technology, used to recycle post-consumer PET into food contact materialsPublication . EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP); Poças, Maria de Fátima TavaresThe EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process RecyPET Hungária (EU register number RECYC0146). The input is hot caustic 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. The flakes are dried and extruded. The output of the extrusion step is cut into pellets in an underwater chamber and then recrystallised. The crystallised pellets may then be fed into a solid-state polycondensation (SSP) reactor. The recycled plastic is intended for manufacture of bottles for soft drinks or water. The applicant provided a challenge test, but the flakes contaminated with the surrogates and the pellets obtained after extrusion and crystallisation were extracted with n-hexane without showing sufficient recovery. The Panel considered the extraction as unreliable and could therefore not conclude on the efficiency of the decontamination process. Furthermore, the flow charts provided by the applicant did not enable a clear identification of the steps relevant for the decontamination efficiency, and no sufficiently clear overview of the operational parameters of the steps of the process and the challenge test was provided. Without this information, a proper safety evaluation could not be performed. The Panel concluded that the process RecyPET Hungária is not sufficiently characterised and the applicant has not demonstrated in an adequately performed challenge test or by other appropriate evidence that the recycling process RecyPET Hungária is able to reduce contamination of the PET input to a concentration that does not pose a risk to human health.
- Safety assessment of the process poly recycling, based on starlinger iV+ technology, used to recycle post-consumer PET into food contact materialsPublication . EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP); Poças, Maria de Fátima TavaresThe EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Poly Recycling (EU register number RECYC171). The input is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, with no more than 5% PET from non-food consumer applications. The flakes are dried and crystallised in a reactor, then extruded into pellets which are further crystallised in a second reactor. Crystallised pellets are then preheated in a third reactor and fed to the solid-state polycondensation (SSP) reactor. Having examined the challenge test provided, the Panel concluded that the drying and crystallisation (step 2), extrusion and crystallisation (step 3) and SSP (step 4) are the critical steps that determine the decontamination efficiency of the process. The operating parameters to control the performance of these critical steps are temperature, gas flow and residence time for the drying and crystallisation step; temperature, pressure and residence time for the extrusion and crystallisation step as well as for the SSP step. 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 for long-term storage at room temperature, with or without hotfill. Trays made of this recycled PET are not intended to be used in microwave and conventional ovens and such use is not covered by this evaluation.
- Safety assessment of the process quinn packaging, based on erema basic technology, used to recycle post-consumer PET into food contact materialsPublication . EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP); Poças, Maria de Fátima TavaresThe EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Quinn Packaging (EU register number RECYC172). The input is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers, with no more than 5% PET from non-food consumer applications. They are heated in a continuous reactor under vacuum before being extruded. Having examined 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 to control the performance of this critical step are temperature, pressure and residence time. 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 0.15 μg/kg food, derived from the exposure scenario for toddlers. Therefore, the Panel concluded that the recycled PET obtained from this 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. Trays made of this recycled PET are not intended to be used in microwave and conventional ovens and such use is not covered by this evaluation.
- Safety assessment of the substance Ln 1,4-benzene dicarboxylic acid (with Ln = La, Eu, Gd, Tb) for use in food contact materialsPublication . EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP); Poças, Maria de Fátima TavaresThe EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of the additive Ln 1,4-benzene dicarboxylic acid (with Ln = La, Eu, Gd, Tb) for use in food contact materials. It is a family of mixtures combining the four lanthanides lanthanum (La), europium (Eu), gadolinium (Gd) and/or terbium (Tb) in different proportions as their 1,4-benzene dicarboxylate complexes, used as a taggant in plastics for authentication and traceability purposes. The powdered additive, not in nano form, is intended to be used at up to 100 mg/kg in polyethylene, polypropylene and polybutene. Materials and articles made of these plastics are intended for contact with all foods types at up to 4 h/100°C or for long-term storage at ambient temperature. In tests with food simulants, migration of each Ln was below 5 μg/kg. The Panel considered that irrespective of the composition of the lanthanides, these would dissociate completely from the terephthalic acid salt under aqueous conditions. Evaluation of the genotoxicity studies provided on the individual complexes (La, Eu, Gd and Tb) and on their mixture, taken together with data available in the scientific literature, allows ruling out concern for genotoxicity. Consequently, the CEP Panel concluded that the substance Ln 1,4-benzene dicarboxylic acid (with Ln = La, Eu, Gd, Tb) does not raise a safety concern for the consumer under the proposed conditions of use and if the migration of the sum of the four lanthanides in ionic form does not exceed 50 μg/kg food.
- Safety assessment of the process AMB, based on bandera technology, used to recycle post-consumer PET into food contact materialsPublication . EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP); Poças, Maria de Fatima TavaresThe EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) evaluated the safety of the recycling process AMB (EU register number RECYC154). The input is washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post-consumer PET containers with no more than 5% PET from non-food applications. It is decontaminated in a reactor at high temperature under vacuum and extruded to sheets. Having examined the challenge test provided, the Panel concluded that two steps, the decontamination in the vacuum reactor (step 2) and the extrusion (step 3), are critical in determining the decontamination efficiency of the process. The operating parameters to control the performance of these critical steps are temperature, residence time and pressure for step 2 and temperature, residence time, pressure and screw speed for step 3. 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 when used up to 100% for the manufacture of materials and articles for contact with all types of foodstuffs for long-term storage at room temperature, with or without hotfill, is not considered of safety concern. Articles made of this recycled PET are not intended to be used in microwave and conventional ovens and such use is not covered by this evaluation.
