​The Circular Materials Transition: What Must Scale by 2030

​A new generation of circular and bio-based material technologies is approaching technical maturity — mycelium leathers and composites, bacterial and algal dyes, seaweed and sargassum-derived polymers and bio-based construction materials. Few, however, have reached industrial scale. The constraint is no longer innovation alone; it is the alignment between procurement, feedstock availability, infrastructure and capital. Without that alignment, technologies remain pilots, supply chains remain linear, and capital remains cautious.

​This session focuses on what must change for circular and bio-based materials to become economically viable at industrial scale in Europe before 2030.

​Together, let's dive into this core question: Which circular and bio-based material pathways can realistically reach industrial scale in Europe (and globally) before 2030 — and what must change for them to get there?
