Rock Flour Company (RFC) taps nutrient-rich glacial rock flour naturally created by Greenland’s glaciers to create a sustainable plant nutrient that can both raise agricultural productivity and sequester CO₂. Field trials in Ghana and Denmark, funded by the Novo Nordisk Foundation, have shown crop-yield increases of up to 30 percent while allowing farmers to cut back on synthetic fertilizers. The company plans to deploy its first commercial project in Greenland, run additional long-term pilot programs, and secure large-scale extraction permits. Funds will also support partnerships with growers and agribusiness groups and accelerate R&D on processing innovations to raise the profile of glacial rock flour in regenerative farming. With Greenland’s glaciers producing more than a billion tons of rock flour annually, RFC positions itself to transform cropland into lasting carbon sinks. The company’s operations are headquartered in Greenland, and it has already attracted a roster of climate-focused investors. RFC’s recent €6.1 million seed infusion provides its initial external capital to fast-track commercialization and scale global outreach.
