designboom.com·Jun 10, 2026

During Copenhagen's 3daysofdesign festival, Project Materia showcased "Materia x Mater," featuring nine artists who created objects from Matek, a new circular material made from discarded coffee shells, sawdust, and recycled plastic. This exhibition explores the transformation of waste into valuable design, challenging traditional notions of material prestige while promoting sustainability in design culture.

Project Materia x Mater exemplifies how circular materials can transition from industrial waste to high-end design, offering a sustainable alternative to traditional materials like stone and marble. The use of Matek, a material composed of coffee shells, sawdust, and recycled plastic, not only challenges the conventional aesthetic norms but also provides a tangible example of integrating sustainability into collectible design. This approach can inspire professionals in design and architecture to explore similar material innovations, promoting sustainability without sacrificing aesthetic or functional value.
