Ambuja Cements Partners With Leilac To Capture 1 Million Tonnes Of CO2 At Sanghipuram

Market snapshot: Ambuja Cements has entered into a strategic collaboration with UK-headquartered Leilac Limited to implement pioneering carbon capture technology at its Sanghipuram facility. This partnership aims to establish one of the world's largest commercial-scale pathways for low-carbon cement production, reinforcing the Adani Group's commitment to achieving Net Zero by 2050. The initiative focuses on Leilac’s unique 'direct separation' technology, which separates CO2 emissions from limestone calcination without requiring additional chemicals.

Data Snapshot

• Targeting capture of over 1 million tonnes of CO2 annually upon successful scaling.
• Projected scaling of 7x to 8x following initial demonstration phase.
• Ambuja Cements reported Q4 FY26 Total Income of ₹11,149.36 crore, up 6.6% YoY.
• Consolidated capacity utilization reached 77% as of March 31, 2026.

What's Changed

• The shift from traditional high-emission calcination to Leilac’s indirectly heated calcination allows for high-purity CO2 capture with minimal energy penalty.
• Integration of hybrid electric heating signifies a move toward 100% renewable energy use in process heating, a first for large-scale Indian cement plants.
• This marks a evolution from simple abatement to industrial-scale carbon capture and utilization (CCU), improving the long-term cost curve of low-carbon building materials.

Key Takeaways

• The partnership supports Ambuja’s SBTi-validated net-zero target for 2050 by addressing hard-to-abate process emissions.
• Successful demonstration at the 6.6 MTPA Sanghipuram plant will create a scalable global model for industrial decarbonization.
• The move provides a competitive edge in green public procurement and international markets with strict carbon regulations.

SAHI Perspective

Ambuja Cements is aggressively positioning itself as a technology leader within the Adani Portfolio. By securing Leilac's technology, Ambuja is not just pursuing environmental compliance but is actively de-risking its future capital expenditure against potential carbon taxes and rising coal prices. The ability to switch between fuel sources and electricity (hybrid heating) offers significant operational flexibility in a volatile energy market.

Market Implications

The cement sector is witnessing a shift where ESG credentials directly impact institutional capital allocation and access to green financing. This move likely increases Ambuja's attractiveness to global sustainability-focused funds. For the sector, it sets a benchmark for 'Green Cement' that competitors like UltraTech and Shree Cement will need to match to protect their market share in high-value infrastructure projects.

Trading Signals

Market Bias: Bullish

Ambuja Cements shows strong momentum with its 155 MTPA capacity target and high EBITDA performance. Q4 FY26 income growth of 6.6% and aggressive decarbonization tech adoption provide a robust growth and margin-protection signal.

Overweight: Cement, Green Technology, Infrastructure

Underweight: Traditional Coal Utilities

Trigger Factors:

• Implementation of the India Carbon Credit Scheme
• Successful integration of Penna and Orient Cement assets
• Trends in domestic limestone and clinker prices

Time Horizon: Medium-term (3-12 months)

Industry Context

The global cement industry is responsible for approximately 7-8% of global CO2 emissions. In India, the second-largest producer, the push toward Net Zero is accelerating under the Paris Agreement commitments. Technologies like Leilac's are critical because process emissions (from limestone breakdown) cannot be solved by renewable energy alone; they require carbon capture.

Key Risks to Watch

• Technological risk associated with scaling carbon capture from pilot to commercial million-tonne levels.
• High initial capex requirements for hybrid electrification retrofits across older plants.
• Regulatory uncertainty regarding the pricing of captured carbon in the domestic market.

Recent Developments

Ambuja Cements has been on a rapid expansion spree, completing the acquisition of Penna Cement for ₹10,422 crore and securing NCLT approval for the Sanghi Industries merger in early 2026. The board recently approved the amalgamation of Orient Cement and ACC to streamline operations under a single platform, targeting a total capacity of 155 MTPA by FY28. Financials remain strong with a cash reserve of over ₹24,000 crore reported earlier in the year.

Closing Insight

As Ambuja Cements integrates its recent acquisitions and pioneers deep-tech carbon solutions, it is transforming from a traditional materials manufacturer into a modern, sustainable industrial powerhouse. This partnership with Leilac is a definitive signal that the future of cement in India will be defined by carbon efficiency as much as volume growth.

FAQs

How does Leilac technology differ from traditional carbon capture?

Traditional methods use chemicals to scrub CO2 from flue gases, which is energy-intensive. Leilac uses indirect heating to separate high-purity CO2 directly from the limestone during calcination, reducing the energy penalty and cost.

What is the expected impact on coal consumption at the Sanghipuram plant?

The hybrid electrification technology is designed to potentially reduce coal consumption to zero by switching to renewable electricity and alternative fuels for process heating.

Will this low-carbon initiative increase cement prices for retail home builders?

While sustainable technologies involve initial investment, they are aimed at long-term efficiency and avoiding carbon taxes. Current market dynamics suggest competitive pricing will continue as manufacturers focus on volume-led growth to hit the 155 MTPA target.
