Living Cement for a Living Planet

Concrete shapes the world you live in, but its environmental toll is massive. Imagine, though, if the buildings around you could grow and breathe, helping to heal the planet. This isn’t science fiction. It’s the vision of CyanoCement. Developed by researchers from the Technion – Israel Institute of Technology, this innovative biocement uses ancient microbes to redefine how we think about construction materials.

At the heart of CyanoCement are cyanobacteria, tiny photosynthetic organisms responsible for Earth’s first oxygen-rich atmosphere. By leveraging these extraordinary capabilities, the team—Perla Armaly, Yuval Berger, Lubov Iliassafov, Keren Rosenblau, Yechezkel Kashi, and Shany Barath—crafted a process where these microbes bind minerals and precipitate calcium carbonate, creating a solid without high emissions.
