Talib Visram of Fast Company reports on Lithos Carbon, which is using rocks to address climate change.
- Lithos Carbon is pulling CO2 from the air using Enhanced Rock Weathering (EWR).
- EWR works by spreading crushed basalt over farmland where it mixes with rainwater to convert CO2 into dissolved bicarbonate.
- The company estimates that three tons of its solution can capture one ton of atmospheric CO2.
- Lithos has been named as a winner in Fast Company’s World Changing Ideas Awards.
“Startup Lithos Carbon, however, is focusing on the land, and a natural tool: basalt, a black igneous rock that’s common on volcanically active islands like Hawaii and Iceland. Lithos recycles existing basalt dust—a quarrying by-product—and spreads it over crop land. When rainwater mixes with the basalt dust, it triggers a chemical reaction that captures and locks up CO2 as bicarbonate.”
