In memory of

Olaf Schuiling

Professor, doctor, geologist, researcher and professor of geochemistry. How you know Olaf depends on where you met him. For us, Olaf will always be the Olivine Father. The founder of the ideology and movement focused on the natural solution of the climate problem. Olaf is the founder of greenSand. The company is built entirely on the scientific research and evidence he has collected over the years.

Taken from nature

Olaf borrowed the Olivine concept against climate change from nature. After a calculation he found out that: If all the CO₂ ejected by volcanoes were still in the atmosphere, then there would be no more life on Earth.

Almost all the excess CO₂ that has entered the atmosphere since the creation of the earth has been removed again by a simple geological process. That process is the weathering of rocks, part of the earth's CO₂ cycle.

1 kg greenSand clears 1 kg CO₂

It has been proven in the lab that greenSand Olivine records its own weight net in CO₂. By using greenSand Olivine as a replacement in as many applications worldwide as possible, we can already permanently capture a large part of the CO₂ surplus in a natural way. The more surface area the more CO₂ we clean up.

Grounded in Science

Mg2SiO4+ 4CO2+ 2H2O => 2Mg2+ + SiO2+ 4HCO

Weather olivine rich rock and sand like iron rusts. The mineral olivine reacts with CO₂ (acid) and water (rain) during weathering. During the chemical reaction, silicate, bicarbonate and magnesium are released again. These are in turn important nutrients for the plants.

Good for soil and air

Because Olivine converts the CO₂ into other substances, it can no longer be released. As long as it does not reach 1600 degrees on Earth, it is a permanent solution for capturing CO₂.

The end product of the chemical reaction also has a deacidifying effect on the soil. Magnesium is a natural substitute for lime, which ensures greener leaves and stronger stems. This makes Olivine healthy for the air and the soil.

The weathering rate

The rule of thumb is: the smaller the gradation, the faster it weathers. Gradations below 1 mm weather up to 70% within the first hundred years.

Even smaller grades, such as our greenSand Olivine powder (found in the sprinklers and buckets), can weather completely (~95%) within 30 years. This powder has a grain size of approximately 30μm (0.03 mm!).

The graph on the right shows the weathering rates based on lab testing. However, we believe that the weathering process is even faster under natural conditions.

Better than trees

Planting trees is often seen as the ultimate climate solution. But did you know that a tree only clears CO₂ after +/- 50 years? In addition, trees release all the captured CO₂ after their lifespan.

Olivine removes the CO₂ permanently. Under normal circumstances, the CO₂ is never released again, even if the stone crumbles. This actually speeds up the weathering!
