greenSand
Enkhuizen, Noord-Holland, NetherlandsRemoves CO2 using Olvine
greenSand focuses on removing certified CO2 using the mineral Olivine. Removal by reactions with olivine is an attractive option, because it is widely available and reacts easily with the (acid) CO2 from the atmosphere. When olivine is crushed, it weathers within a couple of years, depending on the grain size and humidity. The reaction is exothermic but slow. The end-products of the reaction are silicon dioxide, magnesium carbonate, and small amounts of iron oxide.

Until 2011, the farm had been farmed in the traditional method of plowing, discing, harrowing, planting, cultivating, and then harvesting. In 2011, the Cunninghams gave up their farming activities and leased the land to Roger Blunck. Roger suggested to the Cunninghams that they consider “no-till” farming. The Cunninghams agreed. The farm has been farmed continuously since that year by Roger, and his son, Matt, utilizing “no-till.” Upon our purchase of the land, we leased the land to Roger and Matt, and they have continued the “no-till” practice on the farm. Since 2020, we have added cover crops to the land. We are considering incorporating a small grain crop into the traditional corn soybean rotation. The advantage of “no-till” is in the utilization of the decomposition of the previous year’s crop residue into the soil increasing the health of the soil. Healthy soil increases the activity of earthworms in the soil helping with moisture retention in the soil. Also, the residue, and the additional crop cover, help with soil erosion during periods of heavy rainfall. For so long as we own this farm, we will continue with the “no-till” farming operation to promote the health of the soil and to assist in the annual crop production.

The company’s core technology captures CO2 from ambient air and stores it in pressurized buffer tanks where it can be accessed for multiple applications. The modular technology can be set up quickly at any location and scaled to meet the needs of businesses of all sizes.

ECOERA Millenium 1
Falkenberg, SwedenFrom agricultural residue to inertinite biochar carbon form.
The ECOERA Millennium Biochar Carbon Removal (BCR) System removes sky carbon and puts it permanently into safe storage as biochar carbon. Using biochar as carbon storage agent is by far the most efficient carbon removal method as it only removes the carbon, not the whole bulky CO2 molecule. The Biochar is stored in the form of inertinite carbon stable for thousands of years if not millions of years. We sell the carbon removal as CO2 Removal Certificates (CORCs) on various carbon removal marketplaces.
