Mati Carbon
Houston-based carbon removal organization
From Wikipedia, the free encyclopedia
Mati Carbon is a Houston-based carbon removal organization. It uses enhanced rock weathering, a process in which crushed basalt is applied to farmland so that carbon dioxide reacts with water and minerals and becomes bicarbonate.[1][2]
In 2025, Mati Carbon received the $50 million prize in the XPRIZE Carbon Removal competition.[1][3]
History
Technology
Mati Carbon uses enhanced rock weathering to remove carbon dioxide from the atmosphere.[7] The process involves applying crushed basalt to cropland.[1][2][5]
When basalt interacts with water and carbon dioxide, the carbon dioxide is converted into bicarbonate.[3][5][8] The bicarbonate can move through water into rivers, aquifers, or oceans.[3][5] The process also releases minerals from the rock into the soil.[5][8]
Mati Carbon uses soil sampling, geotagging, transport data, and software-based tracking to measure and document its carbon removal process.[5][8]

XPRIZE Carbon Removal
In April 2025, Mati Carbon received the $50 million prize in the XPRIZE Carbon Removal competition.[1][2][3][6][9]
The competition was launched in 2021 and included 1,300 teams from 88 countries.[1][6]
The competition required teams to demonstrate a system for removing carbon dioxide from the atmosphere or oceans and storing it.[5][6]
Mati Carbon and three runner-up teams met the competition requirement of removing at least 1,000 tons of carbon dioxide during the final year of the competition.[2][10]
