Mati Carbon, a startup that employs enhanced rock weathering, won Elon Musk's $100 million XPrize for Carbon Removal by developing a low-tech solution to remove CO2. The company crushes rocks and spreads them on smallholder farms in India, Zambia, and Tanzania, improving soil health and boosting crop yields by over 20%. By sourcing local materials and handling all costs, farmers benefit economically. This method not only captures atmospheric CO2 but also enriches soil with essential nutrients, demonstrating a dual advantage for agriculture and climate action.
For a farming family that might have made $1,500 in a year, making an extra $300 from increased crop yields is a significant change.
We're trying to speed up something that happens naturally... when it rains, rocks slowly break down in a process that captures CO2.
