Concept

We transform bioregional and urban waste streams into circular building materials

What do we do?

To address its impact on waste, pollution, emissions, and resource depletion, the European construction sector must transform. This requires a change in Europe’s material cultures.

BC materials is driving this change by developing, producing, demonstrating, and selling circular building materials at scale. These materials are derived from abundant bioregional and anthropogenic resources, including geo-sourced matter (such as excavated earth), bio-sourced matter (such as agro-waste), and urban-sourced matter (such as construction debris). Our work initiates new material cultures based on these resources.

BC materials does this through 5 activities.

  1. we develop materials and consult construction partners on their use,

  2. we make bespoke materials,

  3. we design and prefabricate objects and constructive systems, 

  4. we train contractors and craftsmen, 

  5. we produce and commercialize a brand of standard circular building materials called Léém.

We experience and demonstrate day-to-day that respecting planetary limits is not a constraint, but a powerful source of regeneration of new material cultures.

Our work extends beyond borders, with bespoke projects successfully executed on other continents, demonstrating that while materials are substantial and their cultures local, our knowledge travels lightly.

Why build with these materials?

  • Low carbon: Our materials do not need fossil fuels or energy-intensive processes to be transformed. They significantly lower the embodied carbon of a building.
  • Circular: We use secondary resources to produce high-value building materials.  At end-of-life, these materials are essentially reversible and infinitely reusable, without loss of quality or addition of energy.
  • Comfort & Health: Our use of unfired, natural materials promotes exceptional indoor air quality and comfort. These materials are non-toxic, free of VOCs, and naturally regulate humidity, stabilize temperatures, and reduce noise.
  • Innovation: We pioneer mix designs and production processes by leveraging cutting-edge scientific methods and industrial technology, ensuring we meet the technical demands of contemporary architecture.
