ABOUT THE COLLABORATION
Our friends at Arda Biomaterials in Bermondsey are on a journey to develop something incredible: a new generation material made from spent barley grain proteins. We have been working together since 2023 to bring their innovation closer to market adaptation.

New Grain™
New Grain is a leather-like material made from beer and whisky waste. Beer brewers and whisky distillers extract sugar from barley grain to ferment into alcohol and leave behind the rest of the grain as waste. Known as ‘brewers spent grain’ (BSG) or ‘draff’, this grain is incredibly protein rich but is normally sold as low-grade cattle feed, or turned into biogas.
Arda extract and transform the protein from waste grain into New GrainTM, an innovative, high-value leather-like material that skips the cow and the plastic.

SHOWCASE PIECES
We worked together with Arda to create several showcase pieces including a version of our Calvert Tote and the bestselling Millais.
The collection was exhibited at multiple material innovation exhibitions including the Future Fabrics Expo 2025.
