Olivine / mineral carbon capture
Olivine is one of the most common minerals on Earth, making up between 60-80% of the Earth's mantle. It can absorb its own mass of CO2 when powdered and scattered on the ground in a process known as mineral carbonation. Olivine, milled down to beach-compatible sand, may also be added to coastal protection projects where it gradually dissolves in the seawater, reducing ocean acidity and removing carbon dioxide from the atmosphere.
Aireal describes olivine as one of the most promising natural materials in the field of carbon capture.
MIT Technology Review describes how olivine carbon-capturing rocks can counteract climate change.
Natural Resources Defense Council describes olivine, a magnesium-iron silicate that absorbs CO2 from the air.
The Olivine Foundation promotes olivine applications to policy makers, governmental institutions, and companies
