Greening of industry is a method to attain sustainable economic growth and promote sustainable economies. It includes policymaking, improved industrial production processes and resource-efficient productivity.
The United Nations Industrial Development Organization (UNIDO) can be given credit of coining the term Green Industries Initiatives. A few years back, UNIDO coined the concept ‘Green Industry’ to place sustainable industrial development in the context of new global sustainable development challenges. Green industry means economies striving for a more sustainable pathway of growth, by undertaking green public investments and implementing public policy initiatives that encourage environmentally-responsible private investments.
Green Industry Initiatives create awareness, knowledge and capacities about what is sustainable. UNIDO works with different governments to support industrial institutions that in turn provide assistance to enterprises and entrepreneurs in all aspects relating to the greening of industry. As an organisation, UNIDO extends support for integrating corporate social responsibility, water management, energy and promotion of eco-friendly processes into the policy framework of an industry.
On the other hand, industrial pollution is generally referred to the undesirable outcome when factories emit harmful by-products and waste into the environment such as emissions to air or water bodies (water pollution), deposition on landfills etc. (land pollution) or emission of toxic chemicals into the atmosphere.
Earth’s atmosphere is a dynamic system of natural gases that are necessary to sustain life, and while it has a defence mechanisms to absorb small quantities of air pollutants, high levels of gases can cause ozone depletion and other problems for living organisms. The main sources of gaseous air pollutants are fuel combustion in stationary sources, such as coal-burning power plants, as well as emissions from automobiles. While these gases are not the only ones contributing to air pollution, they are regarded as dominant sources of this world-wide problem.Carbon oxides: Carbon monoxide (CO) is a poisonous gas, dangerous due to its lack of odour and colour that is released into the atmosphere with the incomplete combustion of fuels, such as coal, wood or other natural sources, as well as exhaust from automobiles. Carbon dioxide (CO2) is the greenhouse gas widely considered the main air pollutant in the earth’s atmosphere. Despite the fact that carbon dioxide is essential to support living organisms, it is considered a dangerous air pollutant caused by human activities such as deforestation and the burning of fossil fuels.
Responsible for more than half of the global warming trend, carbon dioxide restricts infrared radiation leaving the Earth’s surface, causing the "greenhouse effect."Nitrogen oxides: Nitrogen oxides (NOx) are air pollutants that contribute the most contaminants to the earth’s atmospheric. Like carbon oxides, vehicle emissions are a major source of nitrogen oxides, and these air pollutants are easily recognizable by the brown plume or haze that forms over areas with high concentrations of the gases. Nitrogen dioxide (NO2) is one of the most prominent and dangerous air pollutants, and this toxic gas is easily identifiable by its reddish-brown color and distinctive, sharp odour.Sulphur oxides: Sulphur oxides (SOx) are another group of gases polluting the earth’s atmosphere. Of particular concern is sulphur dioxide (SO2), one of the major components of smog and a primary cause of acid rain. While sulphur dioxide is naturally produced by erupting volcanoes, the combustion of sulphur-containing fuels such as petroleum oils and coal have caused this gas to become a dangerous air pollutant that is eating away at the Earth’s fragile atmosphere. Dangerous to both plants and animals, sulphur oxides can injure organic matter when deposited in high concentrations and cause respiratory problems by irritating air passages and lungs.
On November 8, 2017, Delhi earned the unenviable distinction of becoming the most polluted city on Earth. The pollution surged so high that some monitoring stations reported an Air Quality Index of 999, way above the upper limit of the worst category, hazardous. (An extra-sensitive air quality instrument at the US embassy got a reading of 1,010, as you can see in the chart).
The airborne particles and toxic chemicals that make up the smog had choked the 19 million residents of the metropolitan area, where merely breathing the air was, at its worst, like smoking 50 cigarettes in a day. Hospitals reported a 20 percent surge in patients with pollution-related illnesses, and doctors had declared a public health emergency.
We are bringing out a classic case before the readers just to point out that what reckless industrialisation can bring out. In the entire spectrum of pollutants, automobiles cause the highest pollution then comes the power generating plants and close to that is cement industry. Therefore it is pertinent that cement industry initiates green initiatives. Why to take green steps?

  • Cement production is the third ranking producer of anthropogenic (man-made) CO2 in the world after transport and energy generation
  • About 4 – 5 per cent of the worldwide total of CO2 emissions is caused by cement production
  • CO2 is produced at two points during cement production:
  • The first is as a by-product of burning of fossil fuels, primarily coal, to generate the heat necessary to drive the cement-making process. The second from the thermal decomposition of calcium carbonate in the process of producing cement clinker.
  • CaCO3 (limestone) + heat -> CaO (lime) + CO2
  • Production of one tonne of cement results in 780 kg of CO2
  • Of the total CO2 output, 30 per cent derives from the use of energy and 70 per cent results from de-carbonation

Important to realise is that although 5 per cent of the worldwide generation of CO2 is due to cement production, that level of output also reflects the unique and universal importance of concrete throughout the construction industry.Measures adopted by cement
The emission regulations moved from 250 mg/Nm3 to 30 mg/Nm3 progressively on par with the global best practices. The cement Industry is continuously adapting to the latest air pollution control technologies like Electrostatic Precipitators, Bag Filters for achieving lower stack emissions of 30 mg/Nm3. Cement Industry installed Continuous Emission Monitoring Systems and Continuous ambient air quality monitoring stations for on line reporting dust emissions. The provisions of Air (Prevention and Control of Pollution) Act, 1981, National Ambient Air Quality Standards has accelerated the Cement Industry’s efforts to pursue their initiatives more vigorously.Measures to control of water pollution: Cement Industry installed Sewage Treatment Plants and Effluent Treatment Plants to treat this water and to reuse for dust suppression & gardening. It is also doing huge amount of rain water harvesting in their mined out pits. Corporates like ACC, Ambuja and Dalmia Bharat have taken steps at few of their plants to become water positive. Sustainable mining and biodiversity conservation: All captive mines operated by Cement Industry strictly adhere to mining, environmental norms laid by Indian Bureau of Mines, Ministry of Environment & Forest & Climate Control , State Pollution Control Board for eco-friendly mining and safety norms by Directorate General of Mines Safety (DGMS) for safe mining. All cement plant and mine sites complies with earmarking 33 per cent of total land area for the green belt development and afforestation. Wild Life Protection Act (WPA) 1972 is further augmenting the Cement Industry’s efforts in preserving the biodiversity with clear guidance. Hazardous waste management & co-processing:Cement industry generates very limited quantity of hazardous waste such as spent oils and lubricants, grease, etc., which are either co-processed in cement kilns or sold to authorised recyclers. The Hazardous Waste (Management, Handling and Transboundary Movement) Rules, 2008 & amendment 2010 gives a clear guidance to the Industry for safe management, handling and disposal of hazardous waste. Apart from this industry also co-process various waste materials generated by other industry. The kiln of a cement plant is the best suited for processing of waste in the most cost effective manner which none other system offers world over. Today rapid urbanisation has created several problems of disposing off waste either industrial or domestic. The stock of fossil fuels is depleting very fast, we have to look for another source of energy. Therefore processing of waste in cement kilns has vast potential in our country. The technology as such is quite proven in Europe and other advance countries. We need to adapt it to local conditions. TSR (Thermal Substitution Rate) is a per cent age replacement of conventional fuel and the number for some of the countries is as high as 60 per cent where as in our case it is at meagre 4 per cent.
Apart from the above, the cement industry has following various innovations towards the sustainable development. Equipment Innovation: Cement
Industry has taken various energy conservation activities throughout the cement manufacturing process. Some of the notable initiatives are as given are
as under:

  • Advanced dry process kiln with energy efficient cooler with 6/7 stage pre heater
  • Low NOX burners and low NOX calciners to reduce NOX from the kiln
  • Energy-efficient grinding equipment like roller press and VRMs
  • Energy efficient compressors, pumps, lighting, variable speed drives, fans and motors
  • Process optimiser along with advanced energy management system, etc.,

Clinker factor improvement and natural resources conservation: Total cement grade limestone reserve available to meet the industry requirements is 89.86 billion tonne, which are expected to last only for another 40 years. Cement industry has carried out extensive research and development for substituting clinker and to absorbs huge quantities of industrial wastes like fly ash and slag. This not only helps in reduction in CO2 emission but also preserving natural resources like limestone and corrective materials.
Recycling of concrete as of date happens to be far stretched. Concrete mixture has the highest proportion of natural materials like stone chips, sand, water etc. If we are able to make use of used concrete we shall save our natural sources of sand and stones. Cement industry is expected to make investments in processing of used concrete which is not happening. With focus on infra development, the day is not far away when we shall be compelled to explore these options. With confidence we can say that Indian cement industry is on the right track though may be little late on few initiatives. The days ahead of us will see industry becoming greener.

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.
