A Conversation with professor Kevin Van Geem (UGent) on the challenges and progress of chemical recycling

Chemical recycling plays a crucial role in the transition towards a circular economy, offering a solution to tackle the complex waste streams that mechanical recycling cannot handle. In a recent interview, Professor Kevin Van Geem from Ghent University, who is also a member of the Innovation Committee of Catalisti, and Annick Meerschman, Innovation Director at Cefic, explored the current advancements and future challenges of chemical recycling in Europe.

Unlike mechanical recycling, which preserves the chemical bonds in materials, chemical recycling breaks down these bonds, allowing the conversion of more diverse and impure plastic waste into new feedstocks. This process is essential for recycling the 40-50 million tons of plastic waste generated annually in Europe. Professor Van Geem highlighted recent progress in both input and output aspects of the technology:

"On the input side, we’ve made significant advancements in processing impure feeds, allowing us to handle a wider variety of plastic waste. On the output side, we’re focusing on producing high-quality products, such as oils that are free of contaminants like metals."

The interview took place at the cutting-edge Laboratory for Chemical Technology (LCT) pilot facilities of Ghent University, where various chemical recycling technologies are being tested and developed. These facilities also integrate with the pilot steam cracker, creating a one-stop-shop for chemical recycling innovations.  Most recently the new SDR pilot plant was opened at LCT, a project funded by the Moonshot program. 

Professor Van Geem’s work at this facility was recently recognized with a prestigious European Research Council (ERC) grant for his groundbreaking research on the electrification of the chemical industry. 

European innovation

Reflecting on the global landscape, Professor Van Geem expressed concern over Europe’s ability to stay competitive in scaling up chemical recycling technologies. While Europe leads in research and development, it is falling behind in the implementation phase.

"Legislation remains our biggest challenge. It directly impacts the business case for investors. Without clear policies, investments are being directed elsewhere. You can only spend your $1 billion once," he emphasized.

This sentiment aligns with Cefic’s Antwerp Declaration for a European Industrial Deal, which underscores the importance of rapid technological advancement to maintain Europe’s leadership in the sustainable chemicals sector.
