About me

As a creative and disciplined researcher, Roy worked his way up from studying Chemistry at Leiden University of Applied Sciences to a PhD position at Utrecht University under supervision of Prof. Dr. ir. Bert Weckhuysen. Along the way, he completed an internship at Uppsala University under Prof. Sascha Ott and, another two internships at Leiden University under Prof. Dr. Sylvestre Bonnet and Dr. Dennis Hetterscheid. The topics of these internships centered around photo-electrochemistry for sustainable fuel production. Roy is driven by his passion for creating a sustainable and circular global economy.

About my research

Chemical recycling of plastic to chemical building blocks is a promising strategy to deal with plastic waste streams. The main challenge is improving the surface contact between the catalyst and the plastic melt in the cracking reaction. In this work as part of ARC CBBC, we investigate the role of radicals in polyolefin cracking and aim to reduce the viscosity and cracking temperature of the plastic with radical initiators. In this research, Electron Paramagnetic Resonance (EPR) is a cornerstone technique and will provide important information on the nature of the radicals. With the insights gained from this PhD project, plastic recycling will become closer to an industrial standard and plastic waste will become a important feedstock.
