Terradot, São Paulo

Terradot harnesses the power of enhanced rock weathering (ERW) — one of nature's own carbon removal processes — and dramatically accelerates it by spreading finely crushed silicate rocks across Brazilian farmland. When rainwater contacts the powdered rock, a natural chemical reaction converts atmospheric CO₂ into stable bicarbonate ions that are carried into groundwater and ultimately to the ocean, where the carbon remains locked for thousands to millions of years.

Brazil is uniquely positioned for ERW at scale: vast agricultural lands, a warm and wet climate that accelerates weathering reactions, abundant basalt rock deposits, and a national agricultural research infrastructure that provides ideal partnerships for deployment. Terradot works directly with farmers, applying rock dust as part of normal soil amendment practices so that carbon removal is integrated into existing operations without added burden.

Beyond carbon, ERW provides immediate agronomic benefits: crushed silicate rocks raise soil pH, reducing acidity and the need for synthetic lime applications. They also supply essential minerals — calcium, magnesium, silicon — that improve crop yields and soil health. Farmers benefit economically from improved harvests while simultaneously becoming part of a verifiable, durable carbon removal system that contributes to Brazil's climate commitments.
