About this collection

The Polymer Chemistry and Catalysis Science & Technology cross-journal collection on ‘Plastic Conversion’ aims to highlight research that makes use of catalysis to optimise plastic recycling and addresses getting the most value out of plastic waste. Guest edited by George Huber (University of Wisconsin-Madison, USA), Zhibo Li (Qingdao University of Science and Technology, China), Haritz Sardon (University of the Basque Country UPV/EHU, Spain) and Ina Vollmer (Utrecht University, the Netherlands), this special collection recognizes that management of plastic wastes relies on research conducted at the intersection of polymer chemistry and catalysis. 

We hope this collection inspires and informs of the latest research on this important topic.

If you are interested in this collection, why not read this related collection across Materials Horizons, Journal of Materials Chemistry A, B and C on ‘Polymer Upcycling’. This aims to explore the latest developments in materials characterization, polymer design and synthesis, physical chemistry and molecular understanding of plastic decomposition and transformation that contribute to a broad knowledge base for upcycling waste plastics.
