Building With Microbes ApS

Growing Tomorrow’s Materials from Yesterday’s Concrete

Join us in building for a more sustainable future.

No Planet B

Turning a global waste stream into a resilient and local building resource.

Cutting building’s CO emissions

Our technology relies on the cultivation of bio-mass to bind recycled mineral aggregates, utilising minimal energy input and cutting production related emissions.

Large scale implementation with high impact

The highest material emissions in buildings lie in structural elements. By exchanging those with low-emission solutions we can achieve high impact without change. – No change in the way we plan, build or live, just smaller footprints.
