Industrial Mineralization: Repurposing Industrial Waste into Durable Climate Value
The world has a tough equation to crack: Mountains of waste on the ground. Gigatonnes of CO2 in the sky.
What if the two wrongs could make a right?
In this paper, we dive into Industrial Mineralization (IMin), a carbon dioxide removal (CDR) pathway which repurposes alkaline industrial waste such as mine tailings and steel slag to remove atmospheric CO2. It is a pathway to safe, durable, gigatonne-scale carbon removal, transforming liabilities into assets, and waste into repair.
