Turning Brewery Waste into Eco-Leather : Brett Cotten Arda Biomaterials

In this episode of "Gaule’s Question Time," Andrew Gaule (linkedin.com/in/andrew-gaule-aimava) discusses with Brett Cotten (https://www.linkedin.com/in/brett-a-cotten/), co-founder and CEO of Arda Biomaterials (https://arda.bio), to explore a revolutionary approach to sustainable manufacturing. Arda transforms brewery waste—specifically spent grain—into high-performance, leather-like materials without relying on plastics or animal products. Brett, who began his journey in biochemistry and entrepreneurship at Penn State and later Cambridge, shares how his career evolved from biotech food startups to founding Arda with co-founder TJ, an Oxford-trained chemist.
