Location: Various locations in the Netherlands and Belgium, including Graft and Eemnes
Clean-up potential: On average, 1 ton of CO2 is captured per ton of olivine-rich rock dust.
Capturing CO2
Rock dust as a lime substitute
According to greenSand, rock dust is a promising application of olivine-rich rock. It offers farmers a great alternative to using lime to deacidify the soil. The advantage is that the Olivine rock dust removes CO₂ from the air. Because nickel is present in olivine rocks, we were reluctant to use it in agriculture, but the extensive research carried out by Deltares has shown that the nickel in olivine rocks poses no risk and remains far below the standard.
A good soil environment requires certain conditions, with pH and oxygen being the two most important elements. If these are not in order, the absorption of nutrients is limited and there is a greater chance that pathogenic micro-organisms will develop. The Olivine rock dust ensures healthy soil.
So the country
Like the farmer
After a rainy spring, we had to wait a long time before we could start. That gave us the opportunity toONCRAto collect all the necessary information. The rock dust has been applied to the first fields.
The farmers participating in this project receive the greenSand Olivine Stone Flour, in exchange for the opportunity to conduct research and measurements regarding the influence on soil quality and the speed at which the olivine reacts.
Good for everyone
CO2 cleanup project
Do you also want to contribute? We support theOxford Principles, which among other things points out the importance of reducing CO₂ emissions. Otherwise it is literally and figuratively, mopping with the tap open.
In addition, it is important to actually clean up CO₂. Preferably with nature-based solutions where the CO₂ is stored for a long time and there is little chance of it being released again.
By purchasing these CO₂ clean-up certificates you support our mission to help the earth restore balance to the CO₂ cycle.
