Compost and biochar could boost carbon sequestration by crushed rock

Xprize Carbon awarded to a dirt simple carbon removal technology

Mati Carbon walked away with the $50 million grand prize for its enhanced rock weathering program that locks carbon in soils for thousands of years.

Compost and biochar could boost carbon sequestration by crushed rock

Enhanced rock weathering (ERW) is a proposed method of carbon dioxide sequestration that involves spreading crushed silicate minerals on soils to drive chemical reactions that form carbonate minerals: Essentially, the idea is to boost the natural process of rock weathering, in which carbon is transferred from the atmosphere into rocks. But few large-scale field studies of ERW exist, making it difficult to determine the technique's practical feas…

Improved rock alteration (ERW) is a proposed carbon dioxide sequestration method that involves the propagation of silicate minerals crushed on soil to produce chemical reactions that form carbonate minerals: essentially, the idea is to stimulate the natural process of rock alteration, in which carbon is [...]
