Lithos, a Seattle agtech startup that uses basalt rocks to help farmers remove carbon, lands $6.3M

Lisa Stiffler of GeekWire reports that Lithos has raised $6.3 million.

The C3 Take
  • Lithos has created an innovative solution to capture CO2.
  • The startup spreads the dust of crushed basalt onto croplands which, when wet from rain, reacts with water and carbon dioxide to form a dissolved bicarbonate.
  • This process also releases nutrients into the soil which increase crop health.
  • The company sells carbon credits to companies and shares its profit with farmers that they partner with.

“The startup uses software to custom-deploy the basalt rock based on variables such as soil chemistry and crop nutrition. The software also measures carbon removal volume.”
