Pelletized material made from finely crushed, highly weatherable igneous rocks such as basalt is applied to forestland (forested slopes), where it undergoes weathering and fixes atmospheric carbon dioxide underground in the form of bicarbonate ions or stable carbonate minerals.
This technology is a nature-based climate solution that works in harmony with natural ecosystems. It enhances the carbon sequestration function of forests while also contributing to sustainable forest management through benefits such as improved soil nutrient retention.
The following benefits are expected:
1. Carbon Dioxide Removal
Silicate minerals contained in the rock react with soil water, absorbing carbon dioxide and fixing it as bicarbonate ions or carbonate minerals.
This process works synergistically with the natural carbon uptake that occurs as forests grow.
2. Mitigation of Soil Acidification and Improved Soil Fertility
Nutrients released through basalt weathering, including calcium, magnesium, and potassium, are supplied to the soil. These nutrients help suppress soil acidification while promoting plant growth.
