Madaster

Madaster is a digital platform that creates material passports for buildings, enabling circular decisions, reuse, carbon insights and compliance reporting.

By making materials in the built environment transparent and measurable, Madaster helps organisations understand what materials they have, where they are, and what their value and impact are over time. This supports smarter decisions across the full building lifecycle -from design and construction to renovation, maintenance and end-of-life- making it easier to reduce embodied carbon, improve resource efficiency and unlock reuse opportunities at scale.

Madaster is used by asset owners, developers, contractors, designers and public organisations to accelerate the transition to a circular and low-carbon built environment.
