Permanent Atmospheric Carbon Dioxide Removal
At Tephracor, we are dedicated to helping create a healthier planet by decreasing the environmental footprint of agriculture. A better planet depends upon the actions we all take.
Tephracor is focused on improving food production and soil health using natural volcanic materials from the Earth to reduce the need for traditional fertilizers and associated environmental impacts while at the same time mitigating greenhouse gasses.
TephraMax® permanently removes CO2 by accelerating the natural geological process of enhanced weathering of basalt volcanic rock carbon sequestration.
TephraMax® Enhanced Rock Weathering Provides A Significant Permanent Carbon Sequestration Solution With Potential For Gigaton Scale CDR
Carbon Dioxide Removal (CDR) By Enhanced Rock Weathering (ERW)
The basaltic volcanic material in TephraMax® permanently sequesters about 250-350 kg of CO2 per ton of material applied as the weathering of basalt naturally produces soluble bicarbonate ions. CO2 sequestration by TephraMax® is verifiable through measurements of beneficial bicarbonate in soil pore water and runoff using in-situ electrical conductivity and pH meters and by tracing index minerals and trace elements unique to TephraMax®.
How TephraMax® CDR Works:
CO2 in the atmosphere and soil combines with water to form carbonic acid.
Carbonic acid dissolves minerals in the basalt, releasing cations and carbonate ions.
Bicarbonate ions move into porewater solutions or are deposited as soil carbonate.
Dissolved bicarbonate ions are transported through groundwater and streams.
Bicarbonate ions reach the ocean for long-term storage, reducing ocean acidity.
Tephracor Carbon Credits
We permanently sequester carbon from the atmosphere through science-based geological solutions that meet the highest industry standards for certification to create high-quality carbon credits offering farms and landowners a strategic value advantage when using TephraMax. Our science team is data-driven to ensure high-standard verification and reporting.
