Silica accelerates permanent carbon dioxide removal from the atmosphere using enhanced rock weathering in agricultural fields. This process locks away atmospheric carbon while simultaneously regenerating soils and improving crop yields for farmers. The company provides measurable, high-quality carbon removal credits based on robust scientific standards.

Problem
Current climate mitigation efforts rely heavily on emission reductions, yet the scale of atmospheric CO₂ that must be removed to meet 1.5 °C targets far exceeds existing removal capacity. Traditional soil management practices also leave many agricultural lands with suboptimal pH, low nutrient availability, and limited resilience to drought and pests, reducing crop productivity and farmer income.
Solution
Silica deploys enhanced rock weathering (ERW) at farm scale by broadcasting finely milled volcanic silicate material across agricultural fields. The silicate reacts with rainwater and soil carbonates, converting atmospheric CO₂ into stable carbonate minerals that remain sequestered for up to 100 000 years. The company couples this geochemical process with rigorous, science‑backed monitoring to quantify the amount of CO₂ removed and generate verifiable carbon removal credits. Simultaneously, the silicate amendment adjusts soil pH, supplies micronutrients, and improves water retention, delivering measurable yield gains and greater climate resilience for participating farmers. Credits and agronomic data are delivered through a digital platform that supports direct purchase, in‑setting, or project development by corporate and institutional buyers.
Target Audience
Primary customers are large‑scale agricultural producers and smallholder farmers in Latin America seeking agronomic improvements, as well as corporations and carbon‑market participants looking to purchase high‑integrity removal credits or in‑set emissions on their supply chains.
