AI GeneratedDecarbonizing Cement Production at Scale
Problem Definition
Cement production accounts for 8% of global CO2 emissions; current alternatives are cost-prohibitive or geographically limited. We need production methods that match current cement performance at competitive cost within 10 years.
Root Causes
Calcination of limestone (CaCO3 → CaO + CO2) is energy-intensive and chemically mandatory
Alternative binders lack established global supply chains and have unproven long-term durability
Carbon pricing mechanisms are insufficient to justify capital reallocation in developing economies
