Concular - Digital Circular Construction Platform
Berlin · Hamburg · Munich (Germany) · 2020 · Concular GmbH (Berlin, Germany) — Germany's leading circular construction platform
Concular demonstrates that material reuse can move beyond pilot projects and become a scalable market solution. Key impacts include: Significant reductions in construction and demolition waste. Reduced demand for virgin materials and associated emissions. Lower embodied carbon in building projects. Reduced material procurement and disposal costs. Increased transparency and traceability across the material lifecycle. Acceleration of circular economy practices within the built environment sector. The platform is helping transform urban renovation and redevelopment projects into sources of certified, reusable construction materials.
Highlight
Transforming buildings into material banks by connecting digital material passports, standardized audits, and a marketplace that enables construction materials to be reused at scale.
Extended description
The construction sector is responsible for a significant share of global resource consumption, waste generation, and embodied carbon emissions. Yet most materials removed during demolition, renovation, or retrofit projects are still discarded rather than reused.
Concular addresses this challenge by treating the existing building stock as a material bank.Through standardized pre-deconstruction audits, reusable materials are identified, documented, and assigned digital material passports.These materials are then certified and made available through Concular's marketplace for use in new construction and renovation projects.
The platform combines assessment, certification, traceability, and transaction capabilities within a single ecosystem.In addition to its digital infrastructure, Concular operates a network of Urban Mining Hubs that support the recovery, processing, and redistribution of materials.
The initiative contributes to reducing construction waste, lowering embodied carbon emissions, and creating a more circular and resilient construction sector. It also supports compliance with emerging European circular economy and building regulations.
Demonstrated metrics
More than 1 million tonnes of CO₂ emissions avoided through material reuse.
More than 15 million construction materials recovered and reintroduced into new projects.
More than 1,000 buildings audited through standardized pre-deconstruction assessments.
Six Urban Mining Hubs operating across Germany.
Collaboration with major developers, architectural firms, construction companies, and public authorities.

Implementation location & date
Founded in Berlin in 2020.
Implemented across Germany, including projects in Berlin, Hamburg, Munich, and other cities, with expansion into additional European markets.
A flagship example is the redevelopment of Berlin Tegel Airport (TXL), one of Europe's largest urban transformation projects, where material recovery and reuse are integrated into the redevelopment process.
