ZeroEx
ZeroEx develops and scales Enhanced Rock Weathering (ERW) projects to achieve permanent carbon dioxide removal. The company utilizes innovative self-integrating accumulator (SIA) technology for precise measurement, reporting, and verification (MRV) of sequestered carbon. This approach enables the creation of financially viable, verifiable carbon credits addressing residual emissions.

Problem
Atmospheric carbon dioxide levels are rising, necessitating effective and scalable carbon removal solutions to mitigate climate change. Traditional methods of carbon sequestration often lack the permanence and co-benefits needed for long-term environmental sustainability.
Solution
ZeroEx provides enhanced rock weathering (ERW) services to permanently remove atmospheric CO₂. The process involves applying rock powder, a byproduct of gravel production, to arable land, accelerating natural weathering processes that bind CO₂. As the rock powder weathers, it not only sequesters CO₂ but also improves soil quality by releasing essential nutrients and increasing pH levels, reducing the need for liming. The captured CO₂ is transported to the ocean via rivers, where it remains stably bound for thousands of years. ZeroEx manages the entire ERW value chain, from quarry and land exploration to project implementation and independent verification of carbon credits.
Target Audience
ZeroEx targets companies seeking to offset emissions with verifiable, permanent carbon removal credits, as well as farmers interested in improving soil health and receiving compensation for participating in ERW projects.
