# Safety assessment of the process KGL, based on the EREMA Basic technology, used to recycle post‐consumer PET into food contact materials

## TL;DR

This paper evaluates the safety of a recycling process for post-consumer PET used in food contact materials.

## Contribution

The study confirms the safety of the KGL recycling process for food contact materials under specified conditions.

## Key findings

- The KGL process ensures migration of contaminants below safety thresholds for infant and toddler exposure scenarios.
- The decontamination step is critical and controlled by temperature, pressure, and residence time.
- Recycled PET is safe for long-term storage at room temperature but not for microwave or oven use.

## Abstract

The EFSA Panel on Food Contact Materials, Enzymes and Processing Aids (CEP) assessed the safety of the recycling process KGL (EU register number RECYC326), 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 ■■■■■ reactor under vacuum before being extruded. Having examined the challenge test provided, the Panel concluded that the ■■■■■ 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 migrations of 0.1 and 0.15 μg/kg food, derived from the exposure scenarios for infants and toddlers, when such recycled PET is 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 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. Articles made of this recycled PET are not intended to be used in microwave or conventional ovens and such uses are not covered by this evaluation.
