Our dissolution recycling process produces post-consumer recycled materials for plastics used in sensitive food-contact applications. In the European “INCREACE” project, we demonstrated that high-quality purified recyclates can be used in demanding applications by combining material quality, purity, and application safety. We are continuing this work in the newly launched international project “InFACT” where we are establishing an economically viable circular economy infrastructure with 15 partners. All stakeholders in the value chain are involved to ensure that flexible plastic packaging from household waste can be collected, sorted, recycled, and processed into new packaging.
In the “INCREACE” project, we successfully demonstrated the use of recycled materials in food contact applications in collaboration with Vorwerk. For this purpose, the team of experts scanned various used food contact materials. Analyses of unintentionally introduced substances (NIAS) revealed the high level of cleaning required for further use of the material in direct food contact.
We carried out the dissolution recycling in a challenge test using used and shredded Thermomix® steam cooking attachments, where we demonstrated for the first time a purification efficiency of over 99.9%, even for large molecules weighing up to over 800 daltons. This highly effective cleaning process reduced concentrations of relevant substances to such a low level that the material is suitable for use in the lid of a Thermomix® steam cooking attachment.
Even at concentrations below analytical detection limits, our team provides a reliable basis for decision-making: Using migration models, we simulate potential substance migration and were able to confirm compliance with Vorwerk’s stringent material requirements.
