Carbon Direct and Arca are collaborating to bring industrial mineralization carbon removal credits to market. The technology accelerates the natural process of turning alkaline mining and steel waste into stable minerals, permanently storing CO2 for over 10,000 years. Following a successful pilot with BHP, Arca is expanding its deployment to new sites, including projects in Western Australia. The initiative has already secured significant offtake agreements from major buyers like Microsoft and Frontier.

Carbon Direct and Arca are teaming up to turn mine tailings into carbon sinks. They are using industrial mineralization to lock CO2 into rock. It is a practical way to use existing waste piles for CDR.

Using existing mining infrastructure is the smart part here. It avoids the massive energy and land footprints of some other DAC methods. I wonder what the actual energy penalty is per tonne of CO2 removed when you scale this up.

The focus on durability is key. 10,000 years puts this in a different risk category than forestry credits. The real challenge will be the measurement and verification standards for these credits to ensure they are actually permanent.

If this can stabilize tailings while removing carbon, it solves two industrial problems at once. That makes the economics much more attractive for mining companies who already have to pay for waste management.
