What If Bricks Could Grow Instead of Being Fired?
What If Bricks Could Grow Instead of Being Fired?
US engineers are exploring a remarkable alternative to traditional brick manufacturing: using bacteria to turn sand and mineral aggregates into solid construction materials.
The technology, developed by Biomason, uses microbial-induced calcium carbonate precipitation (MICP). Microorganisms help produce calcium carbonate, which binds mineral particles together—creating stone-like materials without conventional kiln firing.
The process can harden materials in less than 72 hours under specific production conditions.
Why does this matter?
🌱 Lower energy demand: Avoiding high-temperature kiln firing could significantly reduce manufacturing energy requirements.
♻️ Circular construction: Recycled and alternative mineral aggregates can potentially become valuable building materials.
🏗️ Biological innovation: Microorganisms become part of the manufacturing process, offering a new approach to material production.
The construction industry is searching for ways to reduce its environmental footprint. Innovations like biocement demonstrate how biology could help reshape the materials we build with.
The future of construction may not only be engineered. It could also be grown.
