Researcher thermoreversible bio-based compatibilizers for plastics recycling
Updated: 20 Mar 2025
A junior researcher position is available within the framework of an explorative innovative science project in the Processing and Performance of Materials section (Processing and Performance) in the Mechanical Engineering Department at Eindhoven University of Technology. The researcher is expected to perform experimental research.
Annually, within the European Union (EU), approximately 26 million tons of plastic waste is generated. Regrettably, less than 30% of this undergoes recycling. Numerous plastic waste recycling streams encompass a heterogeneous mixture of polyolefins such as polyethylene (PE, most widely used plastic, applications in films, foils, bags, bottles, pipes, insulation) and polypropylene (PP, second most widely used plastic, applications in containers, caps, hinges). Due to their large similarity, it is impossible to fully separate them from each other. The inherent incompatibility between PP and PE prevents the formation of a molecularly mixed system and results in their separation into distinct phases (e.g. droplets in a matrix). This impairs the mechanical properties of recycled PE/PP mixtures, thereby constraining their suitability for high-quality products. To address this issue, a compatibilization approach can be employed, resulting in compatibilized PE-PP blends with a refined microstructure and enhanced mechanical properties. To provide a sustainable approach towards compatibilization, we aim at developing a thermally reversible compatibilizer via reactive extrusion. The generated compatibilizer will be analyzed via FTIR and NMR and subsequently, compatibilized blends will be characterized by means of rheology, mechanical characterization, microscopy imaging and X-ray characterization.
