Sanjay Joshi, Chief Projects and Manufacturing Officer, Nuvoco Vistas Corp, discusses the integration of alternative fuels and raw materials (AFR) into cement manufacturing.
Tell us about the alternative fuels and raw materials (AFR) used by your organisation in cement manufacturing.
The AFR usage can decrease environmental impacts, lower consumption of fossil fuels to reduce the economic impact to the cement industry. Fast depleting natural resources like limestone, increased cost of conventional fuels like pet coke and coal, have become a matter of great concern for cement industry all over the world. The high temperature and adequate retention time makes cement kilns most suitable for disposing of alternative fuels. Utilisation of AFR in the cement industry, helps in reduction of the carbon footprint, substituting consumption of fossil fuels and reducing its associated higher cost.
Nuvoco has been a pioneer in this regard, utilising substantial quantities of non-recyclable hazardous wastes, plastics, tire wastes, surplus biomass and RDF as alternative fuels since 2014. To support this initiative, Nuvoco has established comprehensive AFR storage, handling, and feeding facilities in all its plants. Additionally, Nuvoco incorporates alternative raw materials into its cement and clinker raw mix, sourced from industrial and mineral wastes in metallurgy, petrochemicals, chemicals, paper and pulp sectors. These materials include fly ash, slag, metallurgical slags, phosphogypsum and red mud, contributing to a reduced carbon footprint and decreased reliance on fossil fuels and natural conventional raw material.
What factors do you consider when selecting alternative fuels and raw materials?
The selection of AFR for usage in a cement kiln involves a thorough assessment of their potential impacts on clinker and cement manufacturing operations, product quality and the environment. Several important factors must be considered before finalising the choice of AFR.
Among these, key parameters include alkali, sulphur, chloride, trace element content, heat (calorific) value and moisture content. Regular reviews of the acceptance criteria are conducted in accordance with local regulations to ensure ongoing alignment with environmental standards and manufacturing requirements. This comprehensive evaluation
process ensures that the selected AFR optimally contributes to the cement kiln process while
minimising adverse effects on both the product and the surrounding environment.
What is the impact created on the environment by use of AFR in your organisation?
Concerning the co-processing of AFR, the cement industry is actively working towards reducing greenhouse gas emissions and preserving natural resources by incorporating a variety of AFRs in the cement kiln.
To ensure responsible handling, plants have implemented essential infrastructure, including AF storage sheds with impermeable flooring, leachate collection pits, firefighting arrangements and deodorisers, effectively mitigating the environmental impacts of AFR usage. The handling and feeding systems for alternative fuels are centrally operated from the Control Room (CCR), minimising manual interventions throughout the process. Rigorous monitoring and systematic storage procedures are in place for all wastes intended for co-processing in the cement kiln, ensuring a continuous and well-managed approach to environmental sustainability.
Have you faced any challenges or barriers when using AFR in cement production, and if so, how have you overcome them?
Certainly, when incorporating alternative fuels and raw materials, numerous challenges emerge throughout the process. These challenges span from the storage areas, where issues related to non-uniform quality of alternative fuel are encountered, to the pyro system, which has to adapt to process changes and blending during alternative fuel feeding.
In essence, the primary challenges faced in the utilisation of AFR can be succinctly summarised
as follows:
- Non-homogeneity of the waste: Wastes received by cement plants have varying chemical compositions, which initially result in operational disturbances.
- Coating, build-ups and refractory issues: The high content of chlorine and alkalis in hazardous solid waste combined with pet coke sulphur results in coating formation. Circulation of volatile salts increases and clogging arises in lower preheater cyclones and riser pipes.
- Availability of odour control system at storage sites.
- Wear and tear of equipment used for waste processing: AFR has different foreign materials like silt, glass, metal pieces so it makes heavy wear and tear of pre-processing equipment like shredder, trommel, belt conveyor, etc.
- Inhouse testing laboratory facilities not being available to check the quality of received material.
- CCR operators not being trained on operational parameters for alternative fuel usage.
- All these issues have been analysed systematically, discussed with suppliers and plant original equipment manufacturers (OEM). Some modifications have been made in the feeding system to avoid operational issues. Process related improvements are executed after discussion with OEM, which results in smooth burning of alternative fuels in the system.
How do you see the use of AFR in cement production evolving in the future, and what role do you think your company will play in this process?
In the current landscape of fuel availability and cost considerations, AFR has become integral to our fuel mix. Government initiatives have played a leading role in raising awareness about AFR usage, resulting in a notable uptick. The proliferation of pre-processing facilities, coupled with in-depth research and consultations with cement industries facilitated by catalyst bodies like Confederation of Indian Industry (CII) and Cement Manufacturers Association (CMA), has positioned co-processing as the preferred choice. This approach not only reduces production costs but also contributes significantly to resource conservation on a broader scale.
At Nuvoco Cement, we have embraced co-processing of AFR in all our integrated cement
plants. Our commitment to sustainability is evident through the adoption of new technologies aimed
at increasing the utilisation of AFR. We remain dedicated to continuously exploring and implementing innovative technologies across all our plants, demonstrating our proactive stance towards environmental responsibility.

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.
