Lucía Mora Fernández, a student on the Master's Degree in Chemical Engineering at the Universitat de València, defended her Master's Degree Final Project in July 2025 named ‘Optimisation of the polyolefin decontamination process by supercritical CO₂ assisted extrusion for food contact applications’
The final project was developed at AIMPLAS and co-supervised by José David Badia Valiente and Alicia Barbas Sánchez. Directed by José David Badia Valiente and Alicia Barbas Sánchez.
The study showed that supercritical CO₂ assisted extrusion allows post-consumer polyolefins to be decontaminated while preserving their original properties. The effectiveness of the process varied depending on the type of polymer and the origin of the contamination, proving to be stable, adjustable and suitable for industrial applications. These results support the safe reuse of plastics in demanding sectors.
