Matter has developed Casta, a sustainable material made from grape stalks.
"In a world where waste is a costly burden for both our planet and the companies that produce it, we like to say 'waste is the new luxury'," told Matter. "Our society remains caught in the grips of excessive wastefulness."

A little under 10 years ago, Matter embarked on a transformative journey, upcycling the discards of product development into remarkable, sustainable materials.

"Our mission is two-fold: to replace virgin resources with these sensory, sustainable alternatives and to captivate and educate the final consumer along the way," added Matter.

As a result, Casta is the material crafted from grape stalks – a waste generated during wine production.

This project has been longlisted in the material innovation category of Dezeen Awards 2023.
