About olivine
What is olivine?
Olivine is one of the most common minerals on Earth. This mineral, which owes its name to its characteristic olive-green color, can be found in many places on the Earth's surface, such as in Norway, Italy, and Spain.
Crucial to greenSand's mission is its unique property of being rich in magnesium and having the capacity to capture carbon dioxide (CO₂) and permanently convert it into a calcium compound.
The term "olivine" can refer to both the mineral and the rock in which it occurs. For this reason, we mainly write about olivine-rich rock.
Rock weathering
When the olivine-rich rock comes into contact with water (rain) and CO₂, a chemical reaction occurs. This permanently fixes and stores CO₂ for the long term.
We accelerate this natural process by grinding the rock, which increases the reaction surface and speeds up the effect.
The natural CO₂ cycle has been disrupted. CO₂ reduction is no longer enough to limit the rise in global temperature.
Therefore, removing CO₂ from the atmosphere is a necessary second track within climate policy.
greenSand helps by permanently removing part of the resulting CO₂ surplus to bring the Earth's CO₂ cycle back into balance.
Scalable applications
greenSand Olivine are our products consisting of this olivine-rich rock.
greenSand offers a variety of grain sizes for many applications where sand and stone are used. By spreading olivine in as many places as possible, we give the earth more surface area and capacity to remove CO₂.
