Mafix turns abundant silicate rocks into fast-weathering, carbon-negative silicon fertilizer for farmers, using enhanced rock weathering to improve yields while removing CO2.
Mafix is betting that activated silicate minerals can weather within a growing season, release plant-available silicon that supports crop resilience and yields, and convert atmospheric CO2 into stable bicarbonate, addressing both slow carbon-removal measurement and soil degradation. Its $5.4 million pre-seed round is intended to produce 1,000 tons for larger trials, while the use of spare cement-kiln capacity is the company's bet on scaling without a costly new first-of-a-kind plant.
