Ambuja Cements (Ambuja), the building materials subsidiary of Indian infrastructure firm Adani Group, is evaluating the integration of carbon capture technology at its 6.6 million tonnes per annum Sanghi cement plant in Gujarat, India.
The company has partnered with UK-based clean energy technology firm Leilac on a pilot project that could be scaled to capture more than one million tonnes of carbon dioxide (CO2) annually.
Leilac will supply its steel tube technology, which indirectly heats the kiln to calcine limestone, enabling the production of lower-carbon cement, while generating a concentrated stream of CO2 process emissions.
The high-purity CO2 released during the process rises to the top of the system, where it is captured and kept separate from furnace exhaust gases, simplifying carbon capture and storage or utilisation.
Leilac’s hybrid-fuel technology also supports Ambuja’s decarbonisation strategy by using renewable electricity in the production process.
Karan Adani, Director of Ambuja, said, “[This technology] can reduce process emissions while improving energy efficiency and supporting long-term sustainable growth.”
Ambuja further described the demonstration plant as a step towards large-scale deployment of carbon capture and utilisation (CCU) processes at its manufacturing sites.
Ambuja is the ninth largest cement producer globally, with a cement production capacity of 109 mtpa across 24 integrated manufacturing plants and 22 grinding units.
In 2024, the Global CCS Institute reported that cement production accounts for around 5.8% of CO2 emissions in India, just below global CO2 emissions at 7-8%.
