The brief
- Won $50M XPRIZE Carbon Removal grand prize (April 2025) for spreading basalt on smallholder farms, boosting income up to 20%.
- 35,000+ farmers across Asia and Africa generating millions in income through carbon credits. J.P. Morgan blended finance enables expansion.
- Targets 250,000 farmers by 2030. Operations span USA, India, Zambia, Tanzania; expanding to East Africa and other regions.
Technical approach
Free application for farmers
Mati applies basalt at no cost. As rock weathers, Mati monetizes verified carbon removal through carbon credits and shares benefits with farmers.
Volcanic rock removes CO2
Crushed basalt weathers in soil, converting atmospheric CO2 into stable minerals over decades. Releases nutrients (Mg, K, Si) that improve soil fertility.
Science-backed carbon credits
Mati monitors soil health and carbon sequestration using field measurements and satellite data, generating Verified Carbon Units traded on markets.
Global South focus
Targets tropical and subtropical smallholder regions (India, Sub-Saharan Africa) where soil degradation is acute and weathering is fast.
