CARBON MINERALIZATION MARKET SEGMENTATION ANALYSIS
BY TYPE:
The Carbon Mineralization Market by type is primarily driven by the distinction between in-situ and ex-situ mineralization processes, each addressing different industrial and environmental needs. In-situ mineralization is gaining momentum due to its ability to permanently store CO₂ directly within geological formations, reducing transportation requirements and long-term leakage risks. This approach is strongly supported by government-backed carbon sequestration initiatives, especially in regions with suitable basalt and ultramafic rock formations.
Ex-situ mineralization, on the other hand, dominates commercial scalability due to its flexibility and integration with industrial operations. It enables controlled mineralization using industrial waste streams and captured CO₂, producing value-added materials such as aggregates and construction inputs. The growing emphasis on circular economy models and industrial decarbonization is a key factor accelerating adoption of ex-situ mineralization across cement, steel, and mining industries.
BY TECHNOLOGY:
Technological segmentation plays a critical role in shaping market competitiveness and adoption rates. Technologies such as post-combustion and direct air capture mineralization are gaining traction due to their compatibility with existing industrial infrastructure.
