AEROC uses the power of nature to establish agriculture as a pioneer in climate protection.
A natural process - accelerated to save the climate
Enhanced Rock Weathering (ERW) permanently removes CO₂ from the atmosphere by spreading rock flour from regional quarries onto agricultural land. The rock flour reacts with the CO₂ in the soil to form bicarbonates, accelerating natural rock weathering from centuries and millennia to months and years.

How Enhanced Rock Weathering works
01
Crushing the rock
First, the selected rock, typically basalt, is crushed or ground to increase its specific surface area for chemical reactions. This process step takes place in local quarries. The rock flour is then transported to the field. AEROC handles the entire logistics process, from procurement to delivery of the material.
02
Application on agricultural land
The rock flour is spread on the fields by farmers or contractors. It can also replace liming, as basalt increases the soil's pH.
03
Chemical reaction and carbon capture
After application, the rock flour reacts with the CO₂ present in the soil and the ambient air. This reaction leads to the formation of bicarbonates, which bind the CO₂ from the atmosphere and release valuable plant nutrients.
04
Generation of negative CO₂ certificates
Measuring and verifying the amount of CO₂ captured is the heart of the ERW process. Using state-of-the-art measurement technology and simulation models, it is possible to determine how much CO₂ is removed from the atmosphere annually after the rock flour is spread. In cooperation with certification companies and under the strictest conditions, negative CO₂ certificates can be generated, enabling companies and countries to recover their unavoidable CO₂ emissions.
Your partner in agriculture
We help you to increase the profitability of your farm
Rock flour such as basalt has been used in agriculture for thousands of years to improve soils and increase yields. ERW technology also allows for the storage of large amounts of CO₂. AEROC helps farms generate additional income based on a participation model and reduce ongoing costs by spreading basalt flour on their fields.
