Enhanced Rock Weathering
How it Works
We accelerate natural carbon mineralization on smallholder farmlands by cooperating with farmers to evenly apply finely ground regional basalt rock dust to croplands. This stimulates chemical weathering reactions that dissolve and convert atmospheric CO2 into stable bicarbonate compounds.
This process verifiably and securely removes legacy carbon emissions through mineralisation, both on smallholder farmlands locally and when conveyed to marine environments, improving crop productivity along the way.
The basalt or wollastonite rocks are crushed and spread evenly onto agricultural lands in collaboration with farmers using specially designed spreading equipment we customize.
On farmlands, the fine particles react with carbon dioxide dissolved in rainwater. This converts atmospheric CO2 into dissolved bicarbonate ions and essential soil macro and micronutrients that improve fertility.
Through a precise scientific methodology, we accurately monitor the CO2 conversion rate from basalt weathering.
The bicarbonate formed gets incorporated into inland water table aquifers and transported via streams and rivers, eventually settling in stable solid carbonate mineral deposits.
Our initiative includes careful tracking to monitor and verify persistent storage without leakage throughout the process.
Over centuries, these carbonate sediment plaques remain isolated from the atmosphere – verifiably having removed legacy carbon emissions through natural mineralization occurring onsite and during inland aquatic transit.
ERW Co-benefits
Our Enhanced Rock Weathering offers a range of co-benefits beyond its primary goal of mitigating climate change.
Soil Fertility Improvement:
ERW involves spreading crushed silicate rocks, such as basalt on agricultural land. As these rocks weather, they release essential nutrients like magnesium, calcium, and potassium, which are crucial for maintaining soil health and reducing the need for fertilizers.
Agronomic Productivity:
By spreading finely crushed silicate rocks on agricultural lands, the project not only capture atmospheric CO2 but also release essential nutrients into the soil. This natural fertilization process can lead to increased crop yields, supporting global food security and the livelihoods of farming communities.
Water Retention:
The process of ERW improves the soil’s ability to retain water, which is particularly beneficial in areas prone to drought. This leads to more resilient crops and reduced irrigation needs, helping farmers adapt to changing climate conditions.
Creating Green Jobs:
Implementing ERW projects stimulates economic growth by creating new employment opportunities, especially in rural areas. Working with local contractors and communities, these projects can provide jobs that support sustainable practices.
