CircularBuild is a SaaS platform that helps construction companies track, manage, and monetize the circularity of building materials. Inspired by MAECONOMY’s success in turning building materials into auditable, monetisable circular assets, CircularBuild provides a digital ledger and marketplace for reclaimed and recycled materials. The platform allows companies to input material data, verify its origin and composition, and then list it for sale or trade within a network of sustainable builders and developers. This addresses the growing demand for sustainable construction practices and the challenge of making circular economy principles financially viable in the construction industry.
