With a global production volume reaching 52.1 million metric tons, High-Density Polyethylene (HDPE) remains one of the most widely used polymers in the packaging industry. However, meeting the stringent EU regulations—which mandate a 50% recycling rate by the end of 2025 and introduce rigid safety standards for food-contact materials by 2030—presents a massive technical hurdle. Traditional mechanical recycling often fails to remove deeply embedded volatile organic contaminant

From household trash to premium yogurt pots: Can we transform highly heterogeneous plastic waste back into pristine, high-end packaging instead of downcycling it into lower-value products? To answer this question, the Competence Center CHASE, alongside an international consortium of industrial and scientific partners, conducted a comprehensive case study. The project successfully demonstrated the technical feasibility of transforming post-consumer resin (PCR) polypropylene (P
