Ajay Kapur, CEO – Cement Business, Adani Group, explores India’s proactive measures, from embracing renewable energy and waste heat recovery to reducing clinker usage and innovatively repurposing industrial by-products, signaling a promising shift towards sustainable cement manufacturing.

Imagine a world without cement – it’s almost like picturing a skyline without its defining structures. As one of the most commonly used building materials, the manufacturing of cement faces significant challenges in decarbonising. Tackling this challenge goes beyond the ordinary, considering that the cement sector is a major player, contributing up to 7-8 per cent of global greenhouse gas emissions. The significance of this issue is particularly pronounced for India, as we currently hold the dual status of the world’s second-largest producer and consumer of cement. The production capacity of the Indian cement sector is poised to grow to more than 700 million tonnes (MT) over the next five years from around 570 MT now. Consumption on the other hand is also set to grow to 450 MT by 2027.
As the Indian economy expands and continues on this growth path to reach $5 trillion in GDP in the near term and emerge as the world’s third largest economy before the end of the current decade, the environmental challenges will also become more formidable.
Most large cement manufacturers in India have already committed to becoming carbon neutral sometime around the middle of this century and this is also going to contribute to India’s Net Zero ambition set for 2070. The road ahead for Indian cement manufacturers is very similar to what the energy sector faces. India’s economic turnaround that started in 1991 also brought home conversations around the rising and unprecedented levels of consumption of energy to fire up the economy, putting the country under the environmental spotlight, too. Cement production is not only energy intensive but also depends on natural mineral resources. The widespread adoption of well-understood and sustainable cement production practices has been a gradual process, gaining momentum over time. Today, the Indian cement sector is ready to meet sustainability challenges head-on through a whole range of measures that covers the entire value chain in cement manufacturing, leading all the way to increasing the share of green cement on the demand side.

Alternative fuel and raw materials
Being an energy-intensive sector, cement manufacturers have started investing in cleaner sources of energy like solar and wind as captive generation units to run their plants. This shift in no small measure is supported by the falling cost of renewable energy India. Between 2010 and now, the cost of solar modules in India have dropped by more than 80 per cent, making it one of the most sought after sources of clean energy for large industrial units including cement. Similar efforts are also on to move finished cement, packed and bulk on more sustainable or green logistics like soya extract-based biofuel powered shipping. Bulk terminals and grinding units along India’s long coastline can enable the movement of clinker and cement through the sea route at the lowest possible cost.
The share of green energy is further enhanced through investments in Waste Heat Recovery Systems (WHRS). These systems not only adhere to the principles of the circular economy but also result in fossil fuels savings. This not only nurtures a more cost-efficient process but also directly impacts the bottom line.
According to the Ministry of New and Renewable Energy (MNRE), the Indian cement Industry has the highest potential to adopt WHRS as an alternative to conventional sources of energy. WHRS installations will continue to grow along with the increase in capacity to manufacture cement, bringing it close to 1.3 GW at current production capacity levels. It is estimated that WHRS would help replace the energy requirement equivalent to 8.6 million tonnes of coal, resulting in emissions savings of 12.8 million tonnes of CO2 by the Indian cement manufacturers.
Cement manufacturers are also cutting down on the ‘clinker factor’ by replacing them with industrial by-products without compromising the quality (strength) of the cement. Cutting down the clinker factor offers two immediate benefits. One, it reduces energy consumption because clinker is produced at ~1400°C (from limestone etc.,) and two, it also softens the environmental impact of by-products like flyash, slag and silica fumes. Manufacturing a tonne of Ordinary Portland cement also releases around 800 kg of CO2. Investments are also made in recycling massive quantities of municipal waste into Refuse Derived Fuel or RDF through its pre- and co-processing facilities, which is then used as energy to run cement kilns. The impact of producing and using RDF not only saves on energy from conventional sources but also helps large cities manage municipal waste in a safe manner. Mega cities like Mumbai are now working with cement companies to manage municipal waste through a symbiotic relationship that benefits manufacturers and city administrators.
Red mud, a waste derived from aluminium production, is also now used in the cement manufacturing process as an alternative raw material. Again, this helps build a circular economy through utilisation of aluminium industry’s by-products in an environmentally sound manner. Other large industrial sectors like pharmaceuticals also tapped for zero residue of their process waste and ETP sludge. Similarly cement manufacturers are also able to process hazardous wastes released by the automobile and automobile ancillary sector such as chromium, zinc and paint sludge, oil residue and cotton waste.
Water management is yet another area that is making cement manufacturing in India more sustainable. Apart from becoming water positive (returning more water than what is consumed) from an operations point of view, a lot is also being done under the larger banner of CSR where cement manufacturers are now active participants in water conservation projects, working along with local rural communities including farmers. Large cement manufacturers in India are also working on conserving biodiversity in their areas of operations including large afforestation projects, which helps in strengthening the water table.

Conclusion
India today has a very robust legislative mechanism to ensure that industrial sectors like cement abide by environmental laws. But cement manufacturers, recognising the growing environmental consciousness among consumers, are actively pursuing higher benchmarks to minimise burden on environmental damage. With the growing consumer centricity that has moved cement from being a commodity to a branded consumer product, manufacturers are now able to offer sustainability as part of the brand value and appeal. Green cement as a product in India is still in its nascent stage with a miniscule share in the overall market. It is expected to grow in coming years as sustainability is an important factor for today’s buyers.
Today’s well-informed consumers also expect manufacturers to play a more responsible role in protecting the environment through sustainable manufacturing practices. The transformation of the Indian cement sector has only begun.

Milind Khangan, Marketing Head, Vertex Market Research, sheds light on Adani’s rapid cement consolidation under its ‘One Business, One Company’ strategy while positioning it to rival UltraTech, and thus, shaping a potential duopoly in India’s booming cement market.

India is the second-largest cement-producing country in the world, following China. This expansion is being driven by tremendous public investment in the housing and infrastructure sectors. The industry is accelerating, with a boost from schemes such as PM Gati Shakti, Bharatmala, and the Vande Bharat corridors. An upsurge in affordable housing under the Pradhan Mantri Awas Yojana (PMAY) further supports this expansion. In May 2025, local cement production increased about 9 per cent from last year to about 40 million metric tonnes for the month. The combined cement capacity in India was recorded at 670 million metric tonnes in the 2025 fiscal year, according to the Cement Manufacturers’ Association (CMA). For the financial year 2026, this is set to grow by another 9 per cent.
In spite of the growing demand, the Indian cement industry is highly competitive. UltraTech Cement (Aditya Birla Group) is still the market leader with domestic installed capacity of more than 186 MTPA as on 2025. It is targeted to achieve 200 MTPA. Adani Cement recently became a major player and is now India’s second-largest cement company. It did this through aggressive consolidation, operational synergies, and scale efficiencies. Indian players in the cement industry are increasingly valuing operational efficiency and sustainability. Some of the strategies with high impact are alternative fuels and materials (AFR) adoption, green cement expansion, and digital technology investments to offset changing regulatory pressure and increasing energy prices.

Building Adani Cement brand
Vertex Market Research explains that the Adani Group is executing a comprehensive reorganisation and consolidation of its cement business under the ‘One Business, One Company’ strategy. The plan is to integrate its diversified holdings into one consolidated corporate entity named Adani Cement. The focus is on operating integration, governance streamlining, and cost reduction in its expanding cement business.
Integration roadmap and key milestones:

  • September 2022: The consolidation process started with the $6.4 billion buyout of Holcim’s majority stakes in Ambuja Cements and ACC, with Ambuja becoming the focal point of the consolidation.
  • December 2023: Bought Sanghi Industries to strengthen the firm’s presence in western India.
  • August 2024: Added Penna Cement to the portfolio, improving penetration of the southern market of India.
  • April 2025: Further holding addition in Orient Cement to 46.66 per cent by purchasing the same from CK Birla Group, becoming the promoter with control.
  • Ambuja Cements amalgamated with Adani Cement: This was sanctioned by the NCLT on 18th July 2025 with effect from April 1, 2024. This amalgamation brings in limestone reserves and fresh assets into Ambuja.
  • Subject to Sanghi and Penna merger with Ambuja: Board approvals in December 2024 with the aim to finish between September to December 2025.
  • Ambuja-ACC future integration: The latter is being contemplated as the final step towards consolidation.
  • Orient Cement: It would serve as a principal manufacturing facility following the merger.

Scale, capacity expansion and market position
In financial year-2025, Adani Cement, including Ambuja, surpassed 100 MTPA. This makes it one of the world’s top ten cement companies. Along with ACC’s operations, it is now firmly placed as India’s second-largest cement company. In FY25, the Adani group’s sales volume per annum clocked 65 million metric tonnes. Adani Group claims that it now supplies close to 30 per cent of the cement consumed in India’s homes and infrastructure as of June 2025.
The organisation is pursuing aggressive brownfield expansion:

  • By FY 2026: Reach 118 MTPA
  • By FY 2028: Target 140 MTPA

These goals will be driven by commissioning new clinker and grinding units at key sites, with civil and mechanical works underway.
As of 2024, Adani Cement had its market share pegged at around 14 to 15 per cent, with an ambition to scale this up to 20 per cent by FY?2028, emerging as a potent competitor to UltraTech’s 192?MTPA capacity (186 domestic and overseas).

Strategic advantages and competitive benefits
The consolidation simplifies decision-making by reducing legal entities, centralising oversight, and removing redundant functions. This drives compliance efficiency and transparent reporting. Using procurement power for raw materials and energy lowers costs per ton. Integrated logistics with Adani Ports and freight infrastructure has resulted in an estimated 6 per cent savings in logistics. The group aims for additional savings of INR 500 to 550 per tonne by FY 2028 by integrating green energy, using alternative fuel resources, and improving sourcing methods.

Market coverage and brand consistency
Brand integration under one strategy will provide uniform product quality and easier distribution networks. Integration with Orient Cement’s dealer base, 60 per cent of which already distributes Ambuja/ACC products, enhances outreach and responsiveness.
By having captive limestone reserves at Lakhpat (approximately 275 million tonnes) and proposed new manufacturing facilities in Raigad, Maharashtra, Adani Cement derives cost advantage, raw material security, and long-term operational robustness.

Strategic implications and risks
Consolidation at Adani Cement makes it not just a capacity leader but also an operationally agile competitor with the ability to reap digital and sustainability benefits. Its vertically integrated platform enables cost leadership, market responsiveness, and scalability.

Challenges potentially include:

  • Integration challenges across systems, corporate cultures, and plant operations
  • Regulatory sanctions for pending mergers and new capacity additions
  • Environmental clearances in environmentally sensitive areas and debt management with input price volatility

When materialised, this revolution would create a formidable Adani–UltraTech duopoly, redefining Indian cement on the basis of scale, innovation, and sustainability. India’s leading four cement players such as Adani (ACC and Ambuja), Dalmia Cement, Shree Cement, and UltraTech are expected to dominate the cement market.

Conclusion
Adani’s aggressive consolidation under the ‘One Business, One Company’ strategy signals a decisive shift in the Indian cement industry, positioning the group as a formidable challenger to UltraTech and setting the stage for a potential duopoly that could dominate the sector for years to come. By unifying operations, leveraging economies of scale, and securing vertical integration—from raw material reserves to distribution networks—Adani Cement is building both capacity and resilience, with clear advantages in cost efficiency, market reach, and sustainability. While integration complexities, regulatory hurdles, and environmental approvals remain key challenges, the scale and strategic alignment of this consolidation promise to redefine competition, pricing dynamics, and operational benchmarks in one of the world’s fastest-growing cement markets.
