Avantium is a pioneering commercial-stage company focused on renewable and circular polymer materials. Avantium develops and commercializes innovative technologies for the production of materials based on sustainable carbon feedstocks, i.e., carbon from biomass or carbon from the air (CO2). The most advanced technology is the YXY® Technology, which catalytically converts plant-based sugars into FDCA (furandicarboxylic acid), the key building block for the sustainable plastic PEF (polyethylene furanoate). PEF is known under the brand name Releaf®, an EU registered trademark of Avantium. Avantium has successfully demonstrated the YXY® Technology at its pilot plant in Geleen, the Netherlands. The FDCA Flagship Plant was officially opened in October 2024 and Avantium is currently in the process of  starting up the world’s first commercial plant for FDCA.

Avantium also provides R&D solutions in sustainable chemistry and is the leading provider of advanced catalyst testing technology and services to accelerate catalyst R&D. Avantium works in partnership with like-minded companies around the globe to develop revolutionary renewable chemistry solutions from invention to commercial scale.
