Project data
Location: Netherlands
Cleanup started: 2023
Cleanup potential: 5,000 tons of CO₂
Weathering rate: approx. 10 years
Cleaning up both debris and CO2
Mixed granulate, which is made from concrete and brick rubble, is widely used as a water-permeable and stable underlay for driveways, car parks and roads, for example. By adding olivine-rich powder you clean up both debris and CO2.
Fast, faster, fastest
In the face of accelerated rock weathering, this is our champion. The powder is only 10-30 um and weathers quickly. At the moment we assume a weathering period of approx. 10 years. See the results of the Deltares field studies for this.
This will help you towards Net-Zero in 2035.
Solid foundation
It is not the most eye-catching CO2 solution, but one with a major impact.
With the recycled rubble and the combination with greenSand's fastest weathering olivine powder, which is created as a residue from a processing process and is reused by us, you create a solid foundation and a sustainable future.
