Rethink What Matters

Rethink What Matters: Material Passports and the Circular Built EnvironmentIn this episode of Rethink What Matters, we welcome Andrea Charlson from Madaster, a pioneering platform focused on enabling a circular built environment through the use of material passports. Together, we explore how data, transparency, and new ways of thinking about materials can reshape the construction industry—and why this matters now more than ever.Buildings are filled with valuable materials, but traditionally, we haven’t kept track of them. Madaster is changing that. By giving every product and material in a building a digital identity—detailing what it is, where it came from, and what can be done with it at the end of its life—we unlock the potential to reuse, resell, or repurpose rather than send things to landfill. This isn’t just good for the planet; it’s smart business.Andrea shares how material passports are gaining traction, especially with tenants, who recognise that interior fit-outs like furniture, finishes, and equipment often have much shorter lifespans than the building’s core. With this data in hand, they can plan upgrades and replacements more intelligently, while reducing waste and cost. It's a compelling value proposition that links sustainability directly to day-to-day decisions.We also discuss Madaster’s integration with BIM (Building Information Modelling), making it easier to generate passports during design and construction. This allows owners, designers, contractors, and even product manufacturers to align on shared, structured data—data that can drive everything from carbon reporting to reuse strategies and residual value estimation.From pilot projects like British Land’s 1 Broadgate to broader regulatory support through London’s circular economy planning requirements and the EU taxonomy, the circular economy is moving from theory to practice. But challenges remain: how do we keep material data up to date over decades? Who owns it? And how do we embed it into everyday property management?Andrea highlights that real transformation will come not just from better materials or smarter tools, but from new business models—ones where ownership, leasing, and take-back schemes are part of the product journey from day one.Whether you’re in property, construction, design, or sustainability, this episode will help you understand how material passports can deliver business value, environmental benefits, and long-term asset resilience. Welcome to the future of buildings—one where nothing goes to waste.
