SCS seeks EFSA authorization of mechanically rPS as food contact material

Source：Adsale Plastics Network Date ：2022-02-11 Editor ：JK

Styrenics Circular Solutions (SCS), a value chain initiative to realize the circular economy for styrenic polymers, has filed its second application for EU authorization of mechanically recycled polystyrene (rPS) as food contact material.

SCS has now already two submissions to be assessed by the European Food Safety Authority (EFSA). Both cover the same multiple end-consumer applications, including yoghurt pots, hot and cold beverage containers and food trays. However, they are based on two different super-cleaning technologies as part of PET-like food contact mechanical recycling processes. The rPS content in end-consumer applications can range up to 100%.

The scientific dossier by Fraunhofer IVV for this second application follows several successful challenge tests performed with the super-cleaning technology of plastic recycling machine manufacturer Gneuss. The process delivers a recycled polymer with high purity, based on post-consumer food packaging waste.

The results were delivered by Gneuss' Multi Rotation System (MRS) jump extrusion process that enables highly efficient super-cleaning based on high vacuum, high surface and melt temperature. Fraunhofer IVV confirmed the good cleaning efficiency demonstrated in the challenge tests.

Styrenics Circular Solutions seeks further EFSA opinion confirming the safety of mechanically rPS as food contact material.

This technology already has an established track record in Japan, where Gneuss have provided FDA approved super-cleaning for food contact mechanical recycling of food trays since 2017.

PET-like high purity mechanical recycling is one of the multiple plastic-to-plastic recycling options available for polystyrene next to dissolution and depolymerization. PS benefits from the same inherent low-diffusion characteristic as PET, which enables mechanical recycling to food grade standards.

While the European Commission has recently presented a draft new regulation on recycled plastics intended to come into contact with foods, SCS is confident that the underlying criteria developed by EFSA to assess the safety of recycling processes remain valid. For SCS' first application, EFSA has set its risk assessment deadline on 23 March 2022.

Jens Kathmann, Secretary-General of SCS, stated, "The submission of this second application for a different super-cleaning technology underlines our confidence in the safety of rPS as food contact material. The expansion of the technological base is important to give investors in food grade mechanical recycling facilities a choice."

Dr. Constanze Hirschhaeuser, Vice President Quality, HSE & Sustainability of PACCOR Packaging GmbH, one of SCS' converter members, emphasized, "This second scientific dossier by Fraunhofer IVV and application for EU authorization is very welcome news by the PS value chain, confirming once again that rPS meets the strict purity requirements for food contact materials."
