Yes, olivine is highly abundant, but due to lack of demand, most of it is currently staying underground. We seek to change that.

We are looking for synergies like that, such as covering eroding beaches, breakwaters, etc with olivine.

If you are interested in sand in construction and otherwise, I highly suggest you check out the book The World in a Grain.

The importance of sand in our everyday life blew my mind. I mean the device you are using right now to access this website, has a processor made out of silicon sand, the screen is made of quartz sand. The building you are in is likely made of aggregate sand, and the road to get to your house etc. But also, don't forget that sand was used to make the lenses for reading that made possible for our older academics, extra decades of research and enabled us to carry out astronomy and to create microscopes...

Sand has shaped the world in such a massive way, and we are hoping it can save us from our CO2 problems as well.


a processor made out of silicon sand, the screen is made of quartz sand

The processor is made from silicon, plus trace amounts of aluminum, glass, and other materials. Silicon is smelted from silica, which is silicon dioxide; same difference as hydrogen gas and water, iron and rust, or aluminum and ruby. The common crystalline form of silica is quartz, which is the most common sand (precisely because olivine sand weathers). Most glass, including the glass used in lenses today, is a non-crystalline blend of typically about 80% silica with other materials, largely to lower its Tg. Other sands (notably garnet and aluminum oxide) are important in optics as abrasives. I hope this clears up some of the confusions you are expressing.

Yes, I was just quickly paraphrasing the major takeaways on the impact of sand and its importance in our lives from the excellent book I referenced, The World in a Grain. Here is an excerpt for you and any others interested:

"He rummages through his knapsack, then pulls out a plastic sandwich bag full of white powder. “I hope we don’t get arrested,” he says. “Someone might get the wrong idea.” ... But it’s the mineral in Glover’s bag—snowy white grains, soft as powdered sugar—that is by far the most important these days. It’s quartz, but not just any quartz. Spruce Pine, it turns out, is the source of the purest natural quartz—a species of pristine sand—ever found on Earth. This ultra‑elite deposit of silicon dioxide particles plays a key role in manufacturing the silicon used to make computer chips. In fact, there’s an excellent chance the chip that makes your laptop or cell phone work was made using sand from this obscure Appalachian backwater. “It’s a billion‑dollar industry here,” Glover says with a hooting laugh. “Can’t tell by driving through here. You’d never know it.” ... Most of the world’s sand grains are composed of quartz, which is a form of silicon dioxide, also known as silica. High‑purity silicon dioxide particles are the essential raw materials from which we make computer chips, fiber‑optic cables, and other high‑tech hardware—the physical components on which the virtual world runs. The quantity of quartz used for these products is minuscule compared to the mountains of it used for concrete or land reclamation. But its impact is immeasurable."


Thank you!

Are you selling your olivine operations as CO2 offsets?

If so, how cost effective would that be vs those offsets that are based on planting trees?
