Our core innovation lies in our mineralization
Flexible CO2 capture from direct air
capture or point source
Developed at the University of Wisconsin-Madison, our unique chemistry implies an integrated CO2 capture and mineralization process.

Using abundantly available minerals
Our process is scalable thanks to its ability to use a broad range of mineral feedstocks
Including:
– Industrial mineral waste: such as fly ash, steel slag, mine tailings
– Natural minerals: such as serpentine or basalt
– Mine tailings: such as copper or iron ore tailings
We have already successfully lab-tested many feedstocks and continue to test more.

Frequently asked questions
1. How energy efficient is your process?
+Our carbon capture + mineralization process uses a completely new approach that is 5 – 15 times more energy efficient than competing technologies.
For instance, when capturing CO2 from the air, incumbent DAC usually require 2000-2500 kWh per ton of purified CO2 and current best in class DAC is at 600 – 800 kWh.
The theoretical minimum (i.e. with infinite time and capex) to separate CO2 from the air is 125 kWh per ton of pure CO2. Further resource is then needed to either use or store the CO2, for instance in geological reservoirs.
Our process is different—we skip the step of producing a purified CO2 stream, instead locking it into our cement replacement. So we’re not limited by the 125 kWh minimum for direct air capture. Our end-to-end process is already down to just 170 kWh per ton of CO2 captured from the air and sequestered.
2. How do you achieve such outstanding efficiency?
+We are the only company globally performing the mineralization reaction in an alkaline environment. This regenerates the CO2 capture solvent during the reaction, eliminating the need for additional energy for solvent regeneration.
3. Which feedstocks can you process?
+Our process works with a wide range of feedstock, including many that wouldn’t typically be viable in construction. We’ve proven our progress using feedstocks including fly ash, serpentine, blast furnace slag, steel slag, silicate minerals and many others. We’re continually testing additional feedstocks.
4. Does your process store carbon permanently?
+Yes, our process permanently stores CO2 in our carbon negative cement replacement.
5. What’s so special about your SCM?
+Not only is it a highly consistent cement replacement, it is also cheaper than Portland Cement or alternative SCMs. It also stores and locks away CO2 captured in the production process.
6. How does your production impact local communities?
+We are committed to ensuring the communities we work within are treated fairly and believe we can impact them positively. By using feedstock that would otherwise end in landfill and providing new employment opportunities, we can help regenerate historically disadvantaged areas (e.g. near closed coal mines).
