RePETito: A project to expand the Circular Economy

Beginning in June 2019, PET household waste such as blister packaging, thermoformed trays and films will be collected and sorted into a total of 6 material types (LAVU / OÖ Landes-Abfallunternehmen GmbH und ARA / Altstoff Recycling Austria AG) The subsequent high quality flake production – including washing and shredding – will be conducted by Kruschitz GmbH.

During the LSP process, the rPET is decontaminated at the molecular level and the polymer chains are extended to increase the Intrinsic Viscosity (IV.)

Teufelberger GmbH uses the rPET to produce strapping with high mechanical strength requirements. Greiner Packaging GmbH produces bottles and thermoformed trays for food and non-food applications. Finally, the products made of rPET are compared with those made of virgin PET.

RePETitio is planned to run until September 2020 and is financially supported by the Upper Austrian government with funds from the “Innovative Upper Austria 2020” strategic economic and research program.

“Together with the Upper Austrian plastics cluster, we were able to initiate this project with leading Austrian companies and see the benefit above all in the lively dialogue to strengthen the recycling economy with PET waste that has so far been little used,” explains Thomas Pichler, managing partner of NGR. 

This project has been co-funded with the support of the LIFE financial instrument of the European Union [LIFE17 ENV/ES/000438] Life programme
