Recycling of polyolefins such as polypropylene and polyethylene continues to be ineffective because of material degradation in mechanical recycling and high energy expenditure in pyrolysis. In this project, we are developing a new catalytic reactive extrusion process in collaboration with Coperion GmbH, Ruhr-University Bochum, and Maastricht University. By leveraging mechanical shear for polymer degradation at lower temperatures, we aim to enhance catalyst efficiency, reduce energy consumption, and obtain higher-value products. Through the integration of spectroscopy and process optimization, we aim to establish a cost-effective and sustainable chemical recycling method that improves plastic waste utilization and reduces its environmental impact.
