Arca is already collaborating with 11 mining companies and pre-sold over C$1 million worth of carbon dioxide removal credits.
“We work with rocks that are naturally reactive – they aren’t reactive when they’re in the ground, they become reactive when they’re mined, but we have a portfolio of technologies that makes sure that we capitalize on the huge reactive capacity of those materials, once they end up as mined waste,” UBC Professor of Geological Sciences and co-founder and Head of Science at Arca Greg Dipple told MINING.com.
Dipple noted the mineral content of the host rock is key, and that the technology works in ultramafic rocks, which are rich in magnesium silicate.
Arca’s technology accelerates carbon mineralization, the…
