Abstract In the context of entry into force of Regulation (EU) 2022/1616, EFSA updated the scientific guidance to assist applicants in the preparation of applications for the authorisation or for the modification of an existing authorisation of a ‘post‐consumer mechanical PET’ recycling process (as defined in Annex I of Regulation (EU) 2022/1616) intended to be used for manufacturing materials and articles intended to come into contact with food. This Guidance describes the evaluation criteria and the scientific evaluation approach that EFSA will apply to assess the decontamination capability of recycling processes, as well as the information required to be included in an application dossier. The principle of the scientific evaluation approach is to apply the decontamination efficiency of a recycling process, obtained from a challenge test with surrogate contaminants, to a reference contamination level for post‐consumer PET, set at 3 mg/kg PET for a contaminant resulting from possible misuse. The resulting residual concentration of each surrogate in recycled PET is then compared to a modelled concentration in PET that is calculated using generally recognised conservative migration models, such that the related migration does not give rise to a dietary exposure exceeding 0.0025 μg/kg body weight (bw) per day. This is the lowest threshold for toxicological concern (TTC) value, i.e. for potential genotoxicity, below which the risk to human health would be negligible. The information to be provided in the applications relates to: the recycling process (i.e. collection and pre‐processing of the input, decontamination process, post‐processing and intended use); the determination of the decontamination efficiency by the challenge test; the self‐evaluation of the recycling process. On the basis of the submitted data, EFSA will assess the safety of the mechanical PET recycling process.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process Cirrec Netherlands BV (EU register number RECYC283), which uses the EREMA Basic technology. The input material is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers, including less than 5% PET from non‐food consumer applications. The flakes are heated in a continuous reactor under vacuum before being extruded. Having examined the challenge test provided, the Panel concluded that the continuous decontamination (step 2), for which a challenge test was provided, is critical in determining the decontamination efficiency of the process. The operating parameters to control the performance of this step are temperature, pressure 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, derived from the exposure scenario for infants when such recycled PET is used at up to 100%. 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 or below, with or without hotfill. This evaluation does not cover uses of the recycled PET in microwaves or conventional ovens.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids was requested by the European Commission to re‐evaluate the risks to public health related to the presence of plasticisers such as phthalates, structurally similar substances and replacement substances, as a consequence of migration from food contact materials (FCMs). As the first part of the two‐part mandate, EFSA was tasked with identifying and prioritising those plasticisers used in FCMs that may warrant further data collection and eventual risk assessment. Close collaboration with the European Chemicals Agency (ECHA) was requested in the mandate. Substances potentially used as plasticisers were identified using Annex II of the mandate, ECHA’s PLASI inventory, the Plastics Regulation and the Regenerated Cellulose Film Directive, the ECHA database, the ECHA grouping approach, and consultation with the Member States. Only substances authorised for FCMs at EU or at national level were prioritised. Five substances classified either as carcinogenic, mutagenic, toxic to reproduction Cat. 1 (under CLP) or as endocrine disruptors, persistent, bioaccumulative and toxic, very persistent/very bioaccumulative (under REACH) were placed into an ‘exclusion group’. Prioritisation was based on the date of the most recent risk assessment in the context of FCM, with substances assessed before 2001 being placed in the high‐priority group, substances assessed between 2001 and 2011 in the medium‐priority group and substances assessed after 2011 in the low‐priority group. For the EU stream, the 76 substances were split into 59 high‐, 14 medium‐ and 3 low‐priority substances. For the nationally authorised stream, the split of the 72 substances is 66, 3 and 3, respectively. The outcome of follow‐up calls for data in support of the exposure assessment will be used for a final ranking.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process RCS Plastics (EU register number RECYC212), which uses the VACUNITE (EREMA basic and Polymetrix SSP V‐leaN) technology. The input material is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers, including no more than 5% PET from non‐food consumer applications. The flakes are heated in a continuous reactor under vacuum before being extruded and pelletised. The crystallised pellets are then preheated and submitted to solid‐state polycondensation (SSP) in a continuous reactor at high temperature under vacuum and gas flow. Having examined the challenge test provided, the Panel concluded that the continuous reactor (step 2) and the SSP reactor (step 4) are critical in determining the decontamination efficiency of the process. The operating parameters to control the performance are temperature, pressure and residence time for steps 2 and 4 as well as gas velocity for step 4. 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. Articles made of this recycled PET are not intended to be used in microwave and conventional ovens and such uses are not covered by this evaluation.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of the substance ‘phosphorous acid, triphenyl ester, polymer with alpha‐hydro‐omega‐hydroxypoly[oxy(methyl‐1,2‐ethanediyl)], C10–16 alkyl esters’ obtained by reaction of ■■■■■ This food contact material (FCM) substance No 1076 was evaluated by the CEP Panel in 2019 for its use in high impact polystyrene. This opinion deals with the safety assessment of the substance when used as an additive at up to 0.025% w/w in acrylonitrile‐butadiene‐styrene (ABS) copolymers. The plastic is intended for repeated use in contact with aqueous, acidic, alcoholic and oil‐in‐water emulsion foods, for long‐term storage at room temperature and below. Migration from ABS formulated with the substance at 0.02% w/w was up to 0.002 mg/kg in 10% ethanol, 0.005 mg/kg in 3% acetic acid and 0.027 mg/kg in 50% ethanol. Migration levels into 50% ethanol declined under repeated‐use test conditions and this decline was considered to also cover repeated contacts with 10% ethanol and 3% acetic acid simulants. The toxicological data are the same as those submitted by the same applicant in a previous dossier (EFSA‐Q‐2018‐00411). They were reported in the scientific opinion of the CEP Panel in 2019 and the conclusions on toxicity are still valid. Overall, the CEP Panel concluded that the substance phosphorous acid, triphenyl esters, polymer with alpha‐hydro‐omega‐hydroxypoly[oxy(methyl‐1,2‐ethanediyl)], C10–16 alkyl esters, does not raise a safety concern for the consumer if it is used as an additive at up to 0.025% w/w in ABS materials and articles for single and repeated use in contact with aqueous, acidic, alcoholic and oil‐in‐water emulsion foods, for long‐term storage at room temperature and below, and if its migration does not exceed 0.05 mg/kg food.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of the recycling process Martogg Group (EU register number RECYC207), which uses the EREMA Advanced technology. The input 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. The flakes are heated in continuous reactors under vacuum before being extruded. The recycled pellets are intended to be 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. The applicant has not provided a proper description of the process, has not demonstrated in an adequately performed challenge test, or provided other appropriate evidence, that the recycling process is able to reduce contamination of the PET flake input to a concentration that does not pose a risk to human health. Therefore, the Panel could not conclude on the safety of the recycling process Martogg Group.

Trays made of this recycled PET are not intended to be used in microwave and conventional ovens and such uses are not covered by this evaluation.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of benzophenone‐3,3′,4,4′‐tetracarboxylic dianhydride (BTDA), FCM substance No 1083, as co‐monomer for the production of polyimides used in repeated use materials and articles that are in contact with acidic and fatty foods at temperatures up to 250°C. Migration of BTDA from a polyimide containing 43% BTDA, ■■■■■ into olive oil was below the limit of quantification of about 3 μg/kg food, and in 3% acetic acid it decreased from 30.3 μg/kg in the first test to 22.1 μg/kg in the third test (2 h/100°C). In a semi‐quantitative screening using acetonitrile and acetonitrile/water to extract the polymer powder, linear and cyclic oligomers were detected at levels below 1 mg/kg material. In thermal desorption of the polymer powder at 250°C, phenol, tentatively identified ■■■■■ were found, but the modelled migrations of these were far below a level of potential concern. ■■■■■. The substance did not induce gene mutations in bacterial and mammalian cells. In an in vitro chromosomal aberration test, the substance was found to be directly clastogenic in the absence of metabolic activation. In an in vivo follow‐up, the substance did not induce the formation of micronuclei in experimental conditions associated with evidence of systemic exposure and therefore the Panel considered that the substance does not raise concern for genotoxicity. The CEP Panel concluded that the use of the substance BTDA is not of safety concern for the consumer if it is applied at up to 43% as a co‐monomer in the production of polyimides for repeated use contact with acidic or fatty foods at temperatures up to 250°C. In addition, the migration of BTDA should not exceed 50 μg/kg.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of N,N‐bis(2‐hydroxyethyl)stearylamine partially esterified with saturated C16/C18 fatty acids (SABOFOG F1), FCM No 1081, which is intended to be used as an antistatic and anti‐fog agent in all types of polymers at up to 2% w/w. It was requested for use in contact with dry food, acidic foods and alcoholic beverages (represented by simulants E, B and C, respectively) with storage up to 6 months at ambient temperature. The migration data provided did not enable the assessment of the safety of applications intended for contact with foods represented by simulants B and C. In the migrate into simulant E, the non‐esterified N,N‐bis(2‐hydroxyethyl)stearylamine was the main constituent. Its mono‐ and di‐esters migrated to a lower extent. According to the data provided, the Panel concluded that the substance does not raise concern for genotoxicity and accumulation in humans. Based on the results of 28‐day oral toxicity study with SABOFOG F1 and on the 90‐day oral toxicity study with the read‐across substance bis(2‐hydroxyethyl)oleylamine, the Panel considered the current SML(T) of 1.2 mg/kg food provided a margin sufficiently large to accommodate the uncertainties related to the read‐across approach. Overall, the CEP Panel concluded that N,N‐bis(2‐hydroxyethyl)stearylamine, of which at least ■■■■■ is partially or fully esterified with saturated C16/C18 fatty acids is not of safety concern for the consumer when used at up to 2% (w/w) in all polymers intended for contact with foods represented by simulant E for up to 6 months at room temperature. Additionally, the migration of the sum of N,N‐bis(2‐hydroxyethyl)stearylamine and its mono‐ and di‐ester, calculated as N,N‐bis(2‐hydroxyethyl)stearylamine, should not exceed 1.2 mg/kg, i.e. the SML(T) for FCM substances 19 and 20, in which also the migration of the mono‐ and di‐ester of N,N‐bis(2‐hydroxyethyl)stearylamine should be included.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process RE‐PET (EU register number RECYC178) which uses the EREMA Basic technology. The input material is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers including no more than 5% PET from non‐food consumer applications. The flakes are heated in a continuous reactor under vacuum before being extruded. The Panel concluded that the continuous reactor (step 2, for which a challenge test was provided) is critical in determining the decontamination efficiency of the process. The operating parameters to control the performance of this step are temperature, pressure 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 derived from the exposure scenario for infants when such recycled PET is used at up to 70% in mixtures with virgin PET and of 0.15 μg/kg food derived from the exposure scenario for toddlers when used at up to 100%. Therefore, the Panel concluded that the recycled PET obtained from this process is not of safety concern when used at up to 70% in mixtures with virgin PET for manufacturing bottles for drinking water and at up to 100% for the manufacture of other materials and articles for contact with all types of foodstuffs, for long‐term storage at room temperature, with or without hotfill. Articles made of this recycled PET are not intended to be used in microwave and conventional ovens and such uses are not covered by this evaluation.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) was asked by the European Commission to update its 2005 risk assessments of di‐butylphthalate (DBP), butyl‐benzyl‐phthalate (BBP), bis(2‐ethylhexyl)phthalate (DEHP), di‐isononylphthalate (DINP) and di‐isodecylphthalate (DIDP), which are authorised for use in plastic food contact material (FCM). Dietary exposure estimates (mean and high (P95)) were obtained by combining literature occurrence data with consumption data from the EFSA Comprehensive Database. The highest exposure was found for DINP, ranging from 0.2 to 4.3 and from 0.4 to 7.0 μg/kg body weight (bw) per day for mean and high consumers, respectively. There was not enough information to draw conclusions on how much migration from plastic FCM contributes to dietary exposure to phthalates. The review of the toxicological data focused mainly on reproductive effects. The CEP Panel derived the same critical effects and individual tolerable daily intakes (TDIs) (mg/kg bw per day) as in 2005 for all the phthalates, i.e. reproductive effects for DBP (0.01), BBP (0.5), DEHP (0.05), and liver effects for DINP and DIDP (0.15 each). Based on a plausible common mechanism (i.e. reduction in fetal testosterone) underlying the reproductive effects of DEHP, DBP and BBP, the Panel considered it appropriate to establish a group‐TDI for these phthalates, taking DEHP as index compound as a basis for introducing relative potency factors. The Panel noted that DINP also affected fetal testosterone levels at doses around threefold higher than liver effects and therefore considered it conservative to include it within the group‐TDI which was established to be 50 μg/kg bw per day, expressed as DEHP equivalents. The aggregated dietary exposure for DBP, BBP, DEHP and DINP was estimated to be 0.9–7.2 and 1.6–11.7 μg/kg bw per day for mean and high consumers, respectively, thus contributing up to 23% of the group‐TDI in the worst‐case scenario. For DIDP, not included in the group‐TDI, dietary exposure was estimated to be always below 0.1 μg/kg bw per day and therefore far below the TDI of 150 μg/kg bw per day. This assessment covers European consumers of any age, including the most sensitive groups. Based on the limited scope of the mandate and the uncertainties identified, the Panel considered that the current assessment of the five phthalates, individually and collectively, should be on a temporary basis.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) was asked by the European Commission to review whether the authorisation of ‘wood flour and fibres, untreated’ (FCM No 96) is still in accordance with Regulation (EC) No 1935/2004. The additive was included in the list of additives for use in plastic food contact materials (FCM) based on the assumption of its inertness. No toxicological evaluation underlying the inclusion of this entry in the positive list is available. In a literature search, general information on the chemical composition of wood was retrieved showing that wood may contain toxic components and contaminants. The information on migration of substances from wood was found to be limited to its use in the production of wine. Data on migration of substances resulting from the use of wood (flour, fibres) as plastic additive were not available. The Panel therefore concluded that there is insufficient information to support that the current authorisation of ‘wood flour and fibres, untreated’ (FCM No 96) is still in accordance with Regulation (EC) No 1935/2004. As a second step, as requested by the mandate, the Panel set out criteria for future evaluations of wood and similar materials from plant origin as additives for plastic for food contact applications. The Panel noted that due to the chemical differences in composition of plant materials, the safety of migrants from these materials must be evaluated on a case‐by‐case basis, considering beyond species also origin, processing, treatment for compatibilisation with the host polymer and assessment of the low molecular weight constituents migrating into food. Migration of substances resulting from using wood or other plant materials should be tested comparatively in samples made with and without the additive. Toxicological data should cover the substances detected in this analysis.

Abstract The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP Panel) assessed the safety of poly((R)‐3‐hydroxybutyrate‐co‐(R)‐3‐hydroxyhexanoate) (PHBH), CAS No 147398‐31‐0 and food contact material (FCM) substance No 1059. This biodegradable copolymer is produced by fermentation of palm oil using a genetically modified microorganism (Cupriavidus necator). Overall migration was up to 5.4 mg/kg. Oligomers are hydroxyl‐terminated or with crotyl‐ and hexenyl end‐groups from dehydration of hydroxyl end‐groups. In the absence of calibration standards, the total oligomer migration was set at the overall migration values. Other degradation products are crotonic acid and (E)‐2‐hexenoic acid. Crotonic acid is authorised for use in FCMs with a specific migration limit (SML) of 0.05 mg/kg food. For (E)‐2‐hexenoic acid, no indication for genotoxicity was identified by the EFSA CEF Panel in its group evaluation of flavouring substances in FGE.05Rev2 (EFSA CEF Panel, ). The other migrating substances detected, ■■■■■, are from the authorised substance ‘palm oil and/or palm fatty acid distillate’ (FCM substance No 9) used as a carbon source for the fermentation and do not give rise to safety concern. A PHBH oligomer mixture was synthesized to simulate that migrating. It did not give rise to concern for genotoxicity. From the repeated dose 90‐day oral toxicity study in rats, the Panel identified the no‐observed‐adverse‐effect level (NOAEL) at the highest dose tested in males, 1,364 mg/kg body weight (bw) per day. The Panel concluded that the potential for bioaccumulation of oligomers is low. Overall, the CEP Panel concluded that the substance PHBH is not of safety concern for the consumer if it is used alone or blended with other polymers in contact with all kinds of food during more than 6 months at room temperature or below, including hot‐fill or a short heating up phase. The specific migration of all oligomers

Abstract The 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.

Abstract This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety evaluation of the recycling process Envases Ureña (EU register No RECYC0147), which is based on the Starlinger Decon technology. The decontamination efficiency of the process was demonstrated by a challenge test. The input of this process is hot caustic washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers, mainly bottles, containing no more than 5% of PET from non‐food consumer applications. In this technology, washed and dried PET flakes are preheated before being submitted to solid‐state polycondensation (SSP) in a continuous reactor (one single reactor or several reactors in parallel) at high temperature under vacuum and gas flow. Having examined the challenge test provided, the Panel concluded that the preheating (step 2) and the decontamination in the continuous SSP reactor (step 3) are the critical steps that determine the decontamination efficiency of the process. The operating parameters that control the performance of the process are well defined and are temperature, pressure, residence time and gas flow for steps 2 and 3. Under these conditions, it was demonstrated that the recycling process under evaluation, using the Starlinger Decon technology, 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 Panel concluded that the recycled PET obtained from this process intended to be 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.

Abstract This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety evaluation of the recycling process PEGRA‐V (EU register number RECYC0137), which is based on the Starlinger IV+® technology. The input of the process 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 consumer applications. In this technology, washed PET 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 three steps, drying and crystallisation, extrusion and crystallisation and SSP are the critical steps that determine the decontamination efficiency of the process. The operating parameters that control their performance are well defined and they are the temperature, the gas flow and the residence time for the drying and crystallisation step, and the temperature, the pressure and the residence time for the extrusion and crystallisation step and the SSP step. Under these conditions, it was demonstrated that the 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 Panel concluded that the recycled PET obtained from this process intended to be 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. Trays made of this recycled PET are not intended to be used, and should not to be used in microwave and conventional ovens.

Abstract This scientific opinion of the EFSA Panel on Food Contact Materials, Enzymes, Flavourings and Processing Aids (CEF Panel) deals with the safety evaluation of the recycling process Veroniki Ecogrup SRL (EU register No RECYC0145), which is based on the Starlinger Decon technology. The decontamination efficiency of the process was demonstrated by a challenge test. The input of this process is hot washed and dried poly(ethylene terephthalate) (PET) flakes originating from collected post‐consumer PET containers, mainly bottles, containing no more than 5% of PET from non‐food consumer applications. In this technology, washed and dried PET flakes are preheated before being submitted to solid‐state polycondensation (SSP) in a continuous reactor at high temperature under vacuum and gas flow. Having examined the challenge test provided, the Panel concluded that the preheating (step 2) and the decontamination in the continuous SSP reactor (step 3) are the critical steps that determine the decontamination efficiency of the process. The operating parameters that control their performance are well defined and are temperature, pressure, residence time and gas flow for step 2 and 3. Under these conditions, it was demonstrated that the recycling process under evaluation, using the Starlinger Decon technology, 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 Panel concluded that the recycled PET obtained from this process and intended to be 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 is not considered of safety concern. Trays made of this PET are not intended to be used, and should not to be used in microwave and conventional ovens.

Abstract 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.
