Why Better Plastic Doesn’t Win Easily: Bart Langius on PEF, Avantium, and Rebuilding Europe’s Materials Base
Bart Langius explains why replacing fossil-based plastics is not just a chemistry challenge, but an industrial one. At Avantium, he is helping bring PEF, a polyester made from plant sugars, from pilot scale into the real market. The conversation moves from Europe’s weakening petrochemical position to the practical hurdles of new materials: cost, scale, customer risk, and existing recycling systems. It is a grounded look at what it really takes to build a new materials category.
