Carbon Direct–Arca Industrial Mineralisation: design and revenue notes for mines
Reviewed by Joe Ashwell
First reported on International Mining – News
30 Second Briefing
Carbon Direct and Arca have formed a partnership to commercialise Arca’s “first-of-its-kind” Industrial Mineralisation (IMin) carbon dioxide removal credits, based on accelerated carbon mineralisation in mine waste. The field-scale system is designed to react CO₂ with magnesium- and calcium-rich tailings to form stable carbonates in situ, turning legacy and ongoing waste streams into long-term carbon sinks. For mine operators, this creates a potential revenue stream from CDR credits while incentivising geochemical characterisation and engineered placement of reactive waste materials.
Technical Brief
- Verification focuses on quantifying net CO₂ removal after subtracting mining, processing and monitoring emissions.
Our Take
The related 28 April piece notes that Arca’s Industrial Mineralization credits are tied to alkaline mine and steelmaking residues, signalling that this collaboration is directly relevant to miners and steel producers looking to monetise waste streams as carbon removal rather than just abatement.
With Carbon Direct already visible in our database alongside buyers such as Microsoft and the Frontier coalition, the tie-up suggests Arca’s technology is being positioned for bankable, third‑party‑verified CDR credits rather than purely internal decarbonisation tools for mine sites.
