In the realm of green cement, various strategies and innovations are being explored to reduce carbon emissions and promote sustainability. The focus is on Southeast Asia, China, India, South Korea, and Australia, where the global cement/clinker market is under discussion.
Key Strategies and Innovations by Region
China
China leads in the deployment of Carbon Capture, Utilization, and Storage (CCUS) technologies, with 11 of 12 operational CCUS projects in Asia. The government has strong regulatory frameworks, financial incentives, and has integrated CCUS into national plans targeting net zero emissions by 2060. China focuses on carbon capture during cement production, reuse of captured CO2, and developing low-carbon cement technologies as part of broader climate commitments.
India, South Korea, Southeast Asia
While specific cement sector data is limited, these regions are recognising the benefits of renewables and energy transition. Strategies likely include growing use of Supplementary Cementitious Materials (SCMs), where available, and gradually adopting CCUS technologies aligned with regional policies.
Australia
With federal government support, Australia is advancing climate policies encouraging innovation in low-carbon cement and related industries. Partnerships like Graymont with Fortera are deploying breakthrough low-carbon cement technologies that chemically reuse industrial CO2 via Fortera’s ReAct™ and ReCarb® systems, scaling production without major plant changes.
Supplementary Cementitious Materials (SCMs)
Across regions, using SCMs such as fly ash, ground granulated blast-furnace slag (GGBS), pozzolan, and limestone reduces clinker demand and CO2 emissions. However, availability varies geographically; for example, North America reports SCM shortages, but stocks are expected to last longer in Asia due to slower industrial decarbonisation, promoting imports and synthetic SCM innovations.
Artificial Intelligence (AI)
Researchers have developed AI models to optimise cement formulations that maintain material quality but drastically reduce carbon emissions, offering a promising pathway for all regions to innovate cement recipes tailored to their resources and requirements.
Summary of Key Decarbonisation Approaches
| Strategy/Technology | Regions Emphasized | Description | |------------------------------|-----------------------------------------------------|-------------------------------------------------------------------------------------------------| | Supplementary Cementitious Materials (SCMs) | All (notably China, Southeast Asia, Australia) | Reduces clinker content by substituting for more carbon-intensive materials | | Carbon Capture, Utilization, and Storage (CCUS) | China (lead), emerging in India, South Korea, Australia | Captures CO2 from production, stores underground or reuses chemically in cement or other products | | Low-carbon cement recipes via AI | Emerging globally | AI-designed cement formulas to minimise emissions while preserving strength | | Carbon reuse technologies (e.g., Fortera's ReAct™ and ReCarb®) | Australia, potentially other regions adopting | Converts industrial CO2 into carbonated cementitious products, scaling with minimal infrastructure change | | Policy and incentives | China, Australia, Southeast Asia | Regulatory support, subsidies, and integration of low-carbon tech into national strategies |
These diverse strategies are driving the transition towards green cement across these Asia-Pacific and Oceania regions by combining material innovation, carbon management technologies, and supportive policies. Clinker substitution and SCMs trade flow are also part of the conversation.
