Enhanced Rock Weathering

Verde has developed partnerships with leading British universities in Soil Science⁷ that have proven Verde’s Product has the potential to capture carbon dioxide from the atmosphere through Enhanced Rock Weathering (“ERW”).

ERW refers to a suite of techniques aimed at accelerating natural rock weathering, which involves the breakdown of minerals and the absorption of CO₂ from the atmosphere. In nature, the process takes centuries as the rocks’ surface is gradually weathered down and reacts with CO₂ to form new stable carbonate minerals or bicarbonate ions, effectively removing CO₂ from the atmosphere and storing it for thousands of years.

By crushing and grinding such minerals and spreading it over large areas, ERW significantly accelerates the absorption of CO₂. The speed of mineral weathering can be calculated using a ‘shrinking core model’, which assumes that the reaction occurs at the surface of the mineral so that the unreacted core gradually shrinks over time.

As detailed by an independent study conducted at Newcastle University under the leadership of Prof. David Manning, PhD, a renowned soil scientist, the carbon dioxide capture properties of the Products are estimated at 120kg per ton. The potential CO₂ removal does not require any change to the Products’ production and farmland application methods, nor does it change the nutritional benefits to plants. Thus, the Products undergo ERW to permanently capture atmospheric CO₂ while releasing potassium and other plant nutrients.

In addition, the Product potentially undergoes mineral dissolution in only a matter of months to a year from its application to soils, faster than the most rapid reacting silicate minerals (forsterite), which takes years to decades for a similar dissolution. Mineral dissolution is directly correlated to the capture of carbon dioxide from the atmosphere, the faster the dissolution the faster the absorption of CO₂. The conclusion was reached by a commissioned study conducted by Phil Renforth, Ph.D., at Heriot Watt University, based on peer-reviewed publication and commercial data.
