Andrea Charlson of Madaster Discusses Material Passports

In this episode of Rethink What Matters, we’re joined by Andrea from Madaster, a platform revolutionising the built environment through the use of material passports. We explore how assigning digital identities to building materials enables smarter decisions, greater transparency, and long-term sustainability—particularly for fit-outs that often have shorter life cycles than a building’s structure. From construction to asset management, material passports are helping property owners, designers, and contractors reduce waste, track carbon, and unlock new business models rooted in the circular economy.
