Whitepaper: Beyond Extraction: Transforming Mine Waste into a Net Zero, Multibillion-Dollar Opportunity
Authored by Arca, nonprofit consultancy The Climate Agency, and former Financial Times Natural Resources Correspondent Will MacNamara, the white paper outlines how mine waste consisting of mafic and ultramafic rock can remove carbon dioxide from the atmosphere at scale—representing one of the great untapped resources for a low-carbon economy.
In this white paper we examine the geological potential, technical innovations, commercial pathways, public incentives and sustainability benefits of this multibillion-dollar opportunity.
