Enhanced Weathering

Enhanced weathering is an accelerated geological process. Mafic and ultra-mafic rocks react with CO2 dissolved in rainwater to form carbonates - permanently locking away the carbon.

Basalt

Crushed basalt is sourced from existing stockpiles, often where it is currently being produced as a by-product in the production of other valuable commodities.

02

Land

Spreading crushed basalt on agricultural land helps to improve the soil health, micronutrient development, water retention, and microbial activity.

Rain

As rain falls it dissolves CO2 in the surrounding air. This forms a dilute carbonic acid. The weak carbonic acid is the reactant in the enhanced weathering process.

04

Mineralisation

The reaction between the basalt and the rainwater permanently sequesters carbon by forming carbonates.
