Abstract

For further improvement of PET-market two items are essential: Development of high-barrier materials (e.g. for sensitive applications like beer-bottles) and technological improvement of PET-recycling. Because of the insufficient elimination of contaminants there was no high-value creation for the mixed and contaminated PET-fraction from post-consumer packaging waste. So the aim of the project was to close the PET-loop for plastic fractions, which are sorted from plastic waste by the German waste management association, 'Duales System Deutschland GmbH'. The project was performed by two industrial partners, the Deutsche Gesellschaft fuer Kunststoffrecycling mbH (German association of plastic recycling) and DuPont de Nemours (Deutschland) GmbH and the Fraunhofer Institute for Process Engineering and Packaging, which has the coordinating part of the process development project. Objectives of the project were the process development, optimisation and scale-up from lab-scale to the technical scale. The process concept was the 'Selective Extraction', a solvent based material recycling process with high purification efficieny. All input materials, multiple PET-containing fractions with different quality concerning contaminants and PET-packaging plastics (transparent, coloured, opaque) were analysed by the Fraunhofer-Institute and characterised during the different process steps. The results of the analytically determined status of additives and contamination lead to optimisation of the recycling process steps. Based on proven technical, economical and ecological feasibility the project-results include all technical data for engineering and for subsequent building up of the aimed industrial recycling plant.
