Amidst water crisis in the population-intense parts of the country, cement companies are striving to make a difference with their approach towards water positivity. With various initiatives such as rainwater harvesting systems, groundwater recharge, recycling and watershed management, groundbreaking work is being done to promote water positivity. ICR takes a closer look at the effects of the water crisis on the Indian cement industry and the measures it is taking to tackle the problem.
Water is one of the most precious resources on Earth and is critical for the survival of all living things. Although the planet has enormous water both on the surface and in the ground, accessible freshwater is minuscule. For India in particular, water is a crucial resource. Our planet is the only known one in the universe that has water and life. Even though 70 per cent of the planet is covered with water, only one per cent is easily accessible. Given that all life forms are dependent on water; its importance cannot be understated for domestic and agricultural use. In addition, water is used to produce power and in multiple processes in multiple industries.
India’s Water Crisis
The ongoing water crisis in India affects nearly hundreds of millions of people each year. A recent report by the National Institute for Transforming India found that most states scored below 50 per cent on the index. If current trends continue, in 20 years an estimated 60 per cent of all India’s aquifers will be at critical or over-exploited levels. India could experience a drop of 6 per cent in its GDP due to water scarcity alone.
Globally, providing clean drinking water is becoming a bigger challenge with population growth. To avert this challenge, the Government of India launched the Jal Jeevan Mission (JJM) in August 2019 to provide safe drinking water to all rural households by 2024. JJM focuses on 1592 water-stressed blocks in 256 districts. The programme will also implement source sustainability measures as mandatory.
Composite Water Management Index (CWMI), a report by NITI Aayog, June 2018, states that India was undergoing the worst water crisis in its history; that nearly 600 million people were facing high to extreme water stress; and about 200,000 people were dying every year due to inadequate access to safe water. The report further mentioned that India was placed at the rank of 120 amongst 122 countries in the water quality index, with nearly 70 per cent of water being contaminated. It projected the country’s water demand to be twice the available supply by 2030, implying severe scarcity for hundreds of millions of people and an eventual loss in the country’s GDP.
Growing Urbanisation and the Cement Market
The Indian Cement Market was valued at US$ 26023.83 million in 2022 and is anticipated to project robust growth in the forecast period with a CAGR of 8.98 per cent, owing to a rapidly increasing mega infrastructure projects, rise in renovation and construction activities says the India Cement Market Report 2022, published by Research and Markets, November 2022.
The report further adds that an estimated 270 million people will be added to India›s urban population between now and 2040. Even with such rapid urbanisation on a massive scale, the proportion of India›s population living in cities is anticipated to be less than 50 per cent by 2040. Most of the structures that will exist in India in 2040 have yet to be constructed.
Water Footprint Assessment Study of Cement Plants, a study by NCCBM, has suggested that the installed capacity of cement production is expected to reach 693 million tonnes by 2025 and 1565 tonnes by 2050. The average water consumption in the cement industry, including mining activity, process, dust suppression, green belt development, captive power plant, domestic and colony comes out to be 0.5 kl/tonne. The water requirement for the Indian cement industry is expected to reach 346.64 million m3 by the year 2025 and 782.77 million m3 by the year 2050.

Moving Towards Water Positivity
According to the report, A Tale to Remember: Growing Water Positive, by Global Cement and Concrete Association, March 2021, the net freshwater withdrawal of GCCA India member companies stood at 49.98 million cubic metre in 2019 and over the years, the best efforts were put in to reduce water consumption during production and other processes. In 2019, ACC Limited reduced specific freshwater consumption by 31 per cent in cement operations, as compared to 2015 baseline.

The report further states that all 128 production plants under GCCA India member companies are Zero Liquid Discharge, reaffirming the commitment to judicious resource use and creating zero negative impact on water sources.
Cement organisations have been proactively working towards optimising and minimising the use of water.
Adani Cement’s cement and building materials companies – Ambuja Cements and ACC Limited, have proactively undertaken a plethora of award-winning water conservation initiatives over the past two decades to address the issue of water scarcity in India. Globally, Ambuja Cements is the only cement maker that has been recognised for its leadership in water security in CDP 2021 with the best ‘A’ score. Ambuja Cements in collaboration with ATE Chandra Foundation had rejuvenated traditional water bodies in Pali District of Rajasthan and Chandrapur district of the Vidarbha region of Maharashtra just in time of the annual monsoon season. Through such efforts, 166 million litres of additional water storage capacities are created by desilting community ponds in 50 villages.

to be twice the available supply by 2030, implying
severe scarcity.
In October 2022, ACC laid down 1000 metres of pipes to supply water for approximately 150 people. ACC has been consistently making collaborative efforts for enhancing availability of water in the rural communities. ACC’s W.A.S.H is an initiative that focuses on providing water for drinking, sanitation and hygiene purposes to communities in rural India. It also aims at rejuvenating, restoring, and creating new water resources. ACC is two times water positive and committed to go up by five times by 2030. Ambuja Cement has already set benchmarks by becoming the only cement company to achieve eight times water positivity.
Keeping in line with Sustainable Development Goal (SDG) 6 – clean water and sanitation, Ultratech Cement conserves water, and is working towards rejuvenating resources through a 3R approach – Reduce, Recycle and Reuse. The organisation is 3.8 times water positive. Initiatives like water demand reduction, rainwater harvesting, groundwater recharge, water recycling, pond deepening, integrated watershed management etc., are standard operating procedures where UltraTech also builds capabilities on water and sanitation-related programmes to ensure the availability of water.
Dalmia Cement (Bharat) Limited, Dalmiapura embarked on their water positivity journey with the aim of reducing the consumption of water and harvesting more water than the consumption by creating structures, as needed. Subsequent to these implementations, the plant was able to achieve a 4.8 water positivity index in 2021, without taking into account an additional harvesting initiative, which was created after the assessment. Motivated with the results achieved, their next step is to take this up and set a new target to become 20 times water positive by 2025. Their roadmap is through creating more rain water harvesting structures to the local communities and making significant quantities of water available.
UCWL converted its limestone mine pits into rainwater harvesting systems, which has led to the organisation becoming 1.7 times water positive in 2021.
The cement sector is growing to meet the urbanisation and infrastructural demands, globally and in India as well. As the second largest cement producer in the world, it becomes important to understand the magnitude of responsibility of these organisations towards the environment and the generations to come. Leading players in the industry are making a continuous effort to reduce the consumption of water and create more than they use, thus becoming water positive. Thus, the cement sector is moving towards a greener tomorrow, so that the future generations, too, can enjoy water in its purest form and can have this basic necessity of their life met with ease.

Efficient Oil Cooling for Gearbox in the Cement Industry. How a High-Performance Plate Heat Exchanger Ensured Thermal Stability and Operational Continuity.
Contributed by: Narendra Joshi and Sourabh Mishra
Application: Gearbox Oil Cooling
Objective: To maintain optimal oil temperature in high-viscosity lubrication systems for gearboxes in cement plants, ensuring uninterrupted operations and minimizing production losses due
to overheating.
Challenge: A prominent cement manufacturing company’s conventional cooling systems were failing to maintain the oil temperature within the optimal range, jeopardizing equipment performance and leading to avoidable downtime.
Background with the Existing System
In heavy-duty industrial applications, particularly in the cement industry, gearboxes are critical components that must operate under high mechanical loads and harsh conditions. These gearboxes rely on lubrication systems where oil plays a dual role, lubrication and heat dissipation. A recurring challenge in such setups is managing the temperature of the gearbox oil. When oil heats beyond a critical limit, its viscosity drops, reducing its ability to form a protective film. This leads to increased friction between components, heat generation, and eventual damage to gearbox components — directly impacting plant uptime and production output.
Delivering Sustainable Heat Transfer Solution with HRS FUNKE High Efficiency Heat Exchanger
This system was selected for its:
- Excellent thermal performance, ensuring rapid and efficient oil cooling even with high-viscosity fluids.
- Leakage-proof operation, with no cross-contamination between cooling water and lubrication oil.
- Robust design, capable of withstanding high operating pressures and variable flow conditions.
The plate exchanger was custom configured based on the oil’s properties, desired outlet temperature, and ambient heat load, ensuring that the oil remained within the specified viscosity range necessary for maintaining gearbox operation and lubrication integrity.
Performance Benefits Delivered
- Oil temperature control and maintained consistently within target range
- Viscosity stability and prevented breakdown of lubrication film
- Equipment reliability and reduced risk of gearbox overheating or failure
- Production continuity and eliminated unplanned stoppages
- Long-Term savings and lower maintenance costs and extended oil life
Solution: To address the problem, HRS Process Systems Ltd recommended the installation of a Funke Plate Heat Exchanger a compact, high-efficiency thermal solution engineered specifically for industrial lubrication oil cooling.
Conclusion: The customer achieved precision oil temperature control, ensuring that the gearboxes operated at optimal conditions. This not only safeguarded the mechanical integrity of the gearbox but also directly contributed to higher plant uptime and improved production efficiency in heavy industries like cement manufacturing.

Jacob Brinch-Nielsen, Vice President of Professional Services, FLSmidth Cement, brings together recommendations from experts across the flow sheet to demonstrate the role of upgrades in optimising the cement manufacturing process.
Improving energy efficiency in material transport
Pneumatic conveying offers a cleaner and more contained alternative to mechanical conveying. However, pneumatic systems can also be energy-intensive, with inefficiencies arising from air leakage, pressure losses, and outdated equipment designs. Optimising these systems can significantly reduce energy consumption and operating costs.
“One major challenge is maintaining efficient air-to-material ratios, as excessive air use leads to unnecessary power consumption,” explains Emilio Vreca, Manager of PT Product Engineering “Leaks in piping and inefficient compressors further compound energy losses. To address these issues, upgrading to the latest pneumatic conveying solutions can yield substantial improvements.”
The latest pump design—the Fuller-Kinyon® (FK) ‘N’ Pump—provides power savings of up to 15 per cent thanks to an improved seal, while an extended barrel and screw design have improved volumetric efficiency by more than 15 per cent. Similarly, the latest generation Ful-Vane™ Air Compressor has been engineered for increased energy efficiency, with an improved inlet area for capturing larger air flows and compatibility with variable frequency drives.
Optimising energy efficiency in packing and dispatch
Even minor inefficiencies in bagging and palletising can lead to higher maintenance demands, increased material waste, and unnecessary energy use. Reducing these inefficiencies is yet another lever to improve overall plant performance and sustainability.
Upgrading rotary packers enhances weighing accuracy, reduces spout-to-spout variations, and lowers reject rates, improving both product consistency and energy efficiency. Similarly, replacing pneumatic drive systems in palletisers with electric alternatives eliminates compressed air dependency, leading to more precise bag handling and reduced energy demand. These targeted upgrades help streamline operations while minimising environmental impact.
A key development in dust control is the FILLPro™ Dust Reduction Kit for GIROMAT® EVO. “By refining material flow and fluidisation, FILLPro reduces dust emissions at the source, improving bagging efficiency and plant cleanliness,” explains Gabriele Rapizza, Proposal Engineer. “This reduces material loss, prevents blockages, and cuts down on maintenance, helping plants achieve a more stable and energy-efficient packing operation.”
How services contribute to increased energy efficiency
In the past, many viewed the role of the supplier as a “sell-and-move-on” model. Things have certainly changed. As cement producers face challenging markets, heightened competition, and increasingly ambitious decarbonisation targets there is little room to tolerate inefficiencies within the plant. The paradigm has shifted such that the value of expert services is as essential as the initial equipment supplied. Furthermore, as digital solutions progress at speed, a fluid, long-term partnership gives cement plants the best platform to take advantage of the latest tools.
Whether it’s an audit to identify why energy efficiency has decreased from one year to the next, or even an optimisation package preparing your plant for carbon capture solutions – we are believers in the principle that there is always more we can do to improve efficiency. For example, our Online Condition Monitoring Services (OCMS) provide continuous monitoring of critical equipment such as the kiln, mills, cooler and fans, aggregating data and utilising advanced algorithms to identify potential trouble spots. As the OEM and an experienced full solutions provider, we can support these services with expert advice, not only alerting you to a problem but also providing recommendations as to how to remedy it or attending site to support you in person.
Small upgrades, big impact
Energy efficiency is a critical factor, influencing both operational costs and sustainability goals. While large-scale innovations such as carbon capture will play an essential role in long-term decarbonisation (and steal the headlines), incremental mechanical upgrades offer an immediate pathway to lower energy consumption with minimal disruption.
By optimising key process areas — grinding, dosing, combustion, cooling, and material transport — you can achieve measurable energy savings while improving performance and flexibility. These solutions provide a strong return on investment and pave the way for a more sustainable cement industry.
