The core technological path of carbon mineralization has shifted from "energy-intensive geological storage" to "industrial synergy of waste-to-waste treatment," and is rapidly entering the industrial demonstration stage, achieving a crucial leap from carbon reduction to value creation.
Three Main Methods of Carbon Mineralization
1. Direct Mineralization of Industrial Solid Waste: Utilizing the calcium/magnesium components in alkaline solid wastes such as steel slag, carbide slag, and fly ash to react with CO₂ to generate stable carbonates (calcite, etc.).
2. Microbial-Induced Mineralization: Microbial metabolism alters the pH of the microenvironment, or cell walls adsorb metal ions, inducing CO₂ to dissolve and precipitate as carbonates.
3. Direct Air Capture Coupled with Mineralization: Directly capturing CO₂ from the air and then reacting it with solid waste for mineralization and storage.
Carbon mineralization will contribute to achieving carbon peaking and carbon neutrality goals.
