Material Passports: Circular Building Solutions with Andrea Charlson, Managing Director, Madaster UK

Andrea Charlson, Managing Director of Madaster UK, explores the transformative role of material passports in circular construction. Andrea discusses Madaster’s mission of documenting and registering material data to promote sustainable reuse and recycling across building lifespans.

As she explains, this approach aligns with growing expectations for transparency and responsible resource management in the built environment.

Andrea explains that Madaster combines the expertise of professionals from both architecture and finance to address the challenges of circular construction. "What we try to do through the platform is enable the registration, documentation, and exchange of material data relating to buildings and infrastructure assets," she shares, emphasising Madaster's data-driven approach to prolong material life cycles.

The system’s layered model allows users to create material passports that provide essential data on the origins, composition, and circularity of each component—ensuring products can be repurposed or recycled within or beyond their original structure.

Guest Quotes:

"The tenants for the building are interested in a passport for their fit out because...they’ll be able to utilise the data that’s in the passport sooner. It’s a stronger value proposition in that way."

"Keeping material passports up to date is going to be a big challenge for the whole industry going forward. After the challenge of creating them, the next challenge will be keeping them up to date."

"The platform is about giving materials and products an identity...they retain it whilst in the built asset, so when no longer needed, they’re much more likely to have a second life."

Key Themes and Discussion Points:

Circular Built Environment: Andrea introduces Madaster’s ambition to connect the built environment through data, creating a closed-loop for building materials by enabling a second life for them. This process reduces waste and resource depletion, contributing to sustainability and efficiency.

Material Passports: Andrea explains that material passports act as a documentation tool, registering each product’s journey, from its initial use to potential future applications. Madaster’s system includes layers to capture data on individual products, components, and larger assemblies within building assets.

Customer Value and Practical Benefits: Madaster’s platform serves a diverse customer base, including asset owners, construction companies, and manufacturers. While asset owners benefit from long-term data availability, construction companies use it to streamline project documentation, and manufacturers can track and update their products’ lifecycle information. This comprehensive data collection supports sustainability and promotes material circularity.

Transparency and Industry Standards: Andrea outlines Madaster’s transparency-driven approach, where data layers can be shared across stakeholders, from design teams to property managers. As London leads with new planning policies requiring circular economy considerations for large developments, Madaster's vision aligns with both regulatory trends and evolving industry expectations.

Sustaining Material Passports Long-Term: Andrea highlights the industry's challenge in maintaining updated material passports, advocating for policies and practices that ensure consistent tracking and maximise data utility. By embedding value-driven KPIs within material passports, Madaster aims to encourage data upkeep and integration into asset management routines.

This episode showcases how Madaster is advancing circularity by leveraging technology and data to redefine sustainability in construction, aligning it with business efficiency and ecological goals.
