Circular Process Streams
In this research area, we focus on circular process streams by transforming data from experiments, production, utilization, and recycling into actionable knowledge. Our work explores how data and knowledge management can enable circular processes and support informed decision-making for complex systems in industrial settings.
Solvent-Based Recycling of High-Density Polyethylene: Evaluation of Decontamination Efficiency Using a DoE Approach
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
