Rock Flour Company

What Rock Flour Company does

Rock Flour Company is a Copenhagen-based agriculture service company, founded in 2023, that commercializes Greenlandic Rock Flour (GRF) — a naturally pre-ground silicate rock powder formed by glacial grinding of bedrock under the Greenland ice sheet and deposited annually in shoreline deposits exceeding one billion tons per year. GRF has an average grain size of 3/1000 millimeters (under 10 microns), a fineness that competing silicate rocks such as basalt or olivine can only match through energy-intensive mechanical crushing requiring approximately 300 kWh per ton. The product functions as a dual-purpose agricultural input: it delivers Potassium, Phosphorus, and micronutrients as a slow-release fertilizer while capturing up to 25% of its weight in CO2 through enhanced rock weathering, with the CO2 locked away as stable bicarbonates for over 100,000 years.

The company operates a partnership-based go-to-market model rather than direct sales. It targets four partner archetypes globally: individual farmers focused on regenerative practices, consortiums and cooperatives, organic fertilizer suppliers as channel partners, and other novel soil health solution providers. Field trials in Ghana and Denmark, funded by the Novo Nordisk Foundation, have demonstrated yield uplifts of up to 30% over multiple growing seasons. Rock Flour Company maintains ongoing engagement with Greenlandic and Danish authorities and local communities to secure legal, environmental, and social acceptance for harvesting operations.

The company has 1–10 employees and an 8-person leadership team including Co-founder and Chief Scientist Minik Thorleif Rosing, CTO Clive Eley, Director Eliot Booth, Agriculture Scientist Laura Dethier, and GHG & Carbon Removal Lead David Oldcorn. No funding rounds, revenue figures, or commercial customers are publicly disclosed; pricing is not published and the company is explicitly in a partnership-development phase seeking collaborators via direct email outreach and its website. Distribution is positioned globally, with effectiveness optimized for warm, wet climates with slightly acidic soils.

Revenue model

1. Greenlandic Rock Flour Product Sales: Rock Flour Company sells Greenlandic Rock Flour (GRF) as a natural, non-toxic plant nutrient solution for climate-friendly crop agriculture. GRF serves dual purposes as an organic fertilizer and carbon sink, with profitable unit economics enabled by its dual benefit as fertilizer and carbon sink. The product is sourced from Greenland glacial deposits and distributed globally to farming operations.

Core offering

Rock Flour Company commercializes Greenlandic Rock Flour (GRF), a 100% natural ultra-fine silicate rock powder sourced from Greenland glacial deposits. The product functions as a non-toxic organic fertilizer providing Potassium (K), Phosphorus (P) and micronutrients to crops while simultaneously capturing up to 25% of its weight in CO2 through enhanced weathering. GRF is distributed globally to farmers, cooperatives, and organic fertilizer suppliers seeking regenerative agriculture and carbon sequestration solutions.

Product overview

Rock Flour Company offers a single core product: Greenlandic Rock Flour (GRF), a naturally occurring, ultra-fine silicate rock powder sourced from glacial deposits in Greenland. The product functions as both an organic fertilizer and a carbon capture solution, providing crops with Potassium (K), Phosphorus (P), and micronutrients while simultaneously capturing atmospheric CO2 through enhanced rock weathering. GRF is the only naturally pre-ground silicate rock, with an average grain size of 3/1000 millimeters, making it uniquely suited for rapid weathering when applied to croplands in warmer climates.
