Building With Microbes ApS

Join us in building for a more sustainable future.

We’re introducing the Micro-Block, recombining industrial waste into structural masonry units, formed by an inaction of fungal mycelium and bacteria. 

OUR MISSION

We want to revolutionize construction materials by growing a bio-based structural material.

With the Micro-Block we aim to ease the construction industries impact on the Earth through Urban Mining, low energy production and cradle-to-cradle material flows. The block’s underlying technology, the microbial interaction binds and protects the building units, harnessing bio-cementing properties for increased mechanical strength.
