Challenge

Industrial CO₂ emissions contribute significantly to global greenhouse gas levels, driving climate change and environmental degradation. A major challenge is capturing CO₂ at the source in a way that is cost-effective and scalable, to be compatible with existing industrial operations.

Solution

Inspired by coral reefs, we use engineered bacteria and enzymes to accelerate the capture of industrial CO₂, combining it with calcium ions to form stable calcium carbonate. This biosustainable method reduces emissions while linking CO₂ and calcium-rich waste streams to create valuable material for reuse in cement, steel, and paper industries—turning waste into industrial value.

Result

By partnering with the cement and steel-manufacturing industrial sectors we aim to validate a scalable platform for point-source CO₂ in high-emission industries. This dual approach—emission reduction and resource recovery—positions the technology as a practical tool for accelerating sustainability across carbon-intensive sectors. Additionally, it provides vital sustainable resources (CaCO3) to the construction sector. Would you like to be a part of this project and see how this technology can improve your CO2 footprint?
