NCB’s ’15th International Seminar on Cement, Concrete and Building Materials’witnessed nearly 1,000 delegates congregate in New Delhi to deliberate on cement, concrete and construction technologies. Stakeholders opined that India had what it would take to assume a leadership role in the global cement business.
It was half past nine in the morning and long queues had already formed at all the registration counters in New Delhi’s sprawling Manekshaw Centre. The waiting crowd, which was growing in numbers with each passing minute, patiently waited to register itself for the biennial National Council for Cement and Building Materials’ – better known by its acronym NCB – ’15th International Seminar on Cement, Concrete and Building Materials’.
Sometime this year, India would overtake the UK and France to become the world’s fifth largest economy in dollar terms, data released by the Centre for Economics and Business Research (CEBR) has predicted. In the past couple of years, the country is back in the reckoning as one of the principle emerging powerhouses of the global economy. But even then, it is rare to come across such overwhelming response to an event catering to a highly-specialised industry.
NCB, the country’s apex body for research, technology development and transfer, education and industrial services in cement, allied building materials and construction industries, started the initiative as early as 1986. Over the years, it has emerged as an important event in South and South-East Asia, attracting a diverse range of stakeholders from the cement and construction space. The four-day seminar was held in the second week of December 2017.
"The objective of this event, eagerly awaited by the industry and the academia alike, is to bring together the captains of the industry and engineering community, on to a common platform for sharing the knowledge on latest innovations and taking India’s growth story forward," noted Ashutosh Saxena, Director General (Acting), NCB.
Notable developments in the areas of Alternate Fuels and Raw Materials (AFRM), climate change, emissions control, Clean Development Mechanism (CDM), ready mix concrete, nanotechnology, etc., were thoroughly discussed. A technical exhibition held simultaneously complemented the forum by providing ready insights into the latest in available technologies and services for efficient operation of cement plants, preparation of concrete and construction activities. A total of 86 firms showcased a diverse range of products and services in automation, instrumentation, grinding, pyro processing, coolers, AFRM utilisation and quality control.
A variety of topics ranging from manpower planning, use of raw materials and AFRM and latest developments in equipment technology were covered at the seminar. Two special technical sessions were also organised. The first, on the subject of ‘Formation and Control of Dioxins in Dry Pre-heater or Pre-calciner Kilns Co-Processing Wastes’, was addressed by the world-renowned expert on pollution and waste management, Dr Kare Helge Karstensen of the Foundation for Scientific and Industrial Research (SINTEF), Norway. Dr Karstensen spoke about the formation and control of dioxins in pre-heater and pre-calciner kilns burning waste materials. The second technical session was a panel discussion on ‘Low Carbon Transitions for the Cement and Concrete Sector, a Global Partnership Approach’. It was moderated by Philippe Fonta, Managing Director, Cement Sustainability Initiative, World Business Council for Sustainable Development (WBCSD). Speakers included Sanjay Jain, AED, Dalmia Cement (Bharat) Ltd, Sivaram Krishnamoorthy, International Finance Corporation (IFC), South Asia and Berthold Kren, Head, Geocycle India. The panel deliberated on means to reduce the industry’s carbon footprint.
This edition saw participation by nearly 1,000 delegates. INDIAN CEMENT REVIEW has learned that over 10 per cent of the delegates were from abroad. The nearly 200 papers presented in the 25 technical sessions at the seminar touched upon new research and innovations in cement, concrete and construction technologies. Over the years, the event has also become the primary platform for the Indian cement industry to discuss recent developments, identify new areas of research, and brainstorm on developing and emerging trends.
Most delegates sounded very satisfied with the event. Rakesh Sharma, Director, AMCL Machinery Ltd, said, "The NCB provides an interesting forum for people from across the cement industry to converge in one place. The opportunity to see the latest developments leaves you wiser at the end of the day." Rajesh Pathak, Director, Sales & Operations, Raymond Bartlett Snow opined, "It makes sense to come here and interact not only with your peers but also potential customers. One also gets to experience firsthand the latest technical knowhow available in the market. It’s an excellent opportunity to share ideas as well as learn from entrepreneurs from all over the globe."
Poised for significant expansion
Today, India is the world’s second largest producer of cement. As per the Government’s Department of Industrial Policy and Promotion (DIPP) and analytics agency CRISIL data, the total installed production capacity for cement in the country stood at over 435 million tonnes (MT), in June 2017. The industry presently produces 280 MT for meeting the domestic demand and 5 MT for export. Even while agreeing that reduced capacity utilisation was affecting the overall efficiency of the production process, NCB’s Saxena emphasised, "The present government is trying to do a lot for development of the housing sector and infrastructure. Therefore, I am very optimistic that within the next six months to one year, the cement industry will get back on course."
The federal Government’s emphasis on infrastructure projects such as focus on affordable housing, construction of roads and highways, development of 100 Smart Cities, interlinking of 60 rivers and development of inland waterways is expected to help the industry grow between 6 to 7 per cent in the 2017-18 fiscal.
The country’s per capita consumption stands at around 225 kg. The domestic consumption of cement is likely to exceed supply over the next three years. The cement industry is expected to grow at a CAGR of 5 to 6 per cent between financial year 2017-20. Moreover, the sector also plays an important role in job creation as it employs over a million people directly or indirectly.
Industry insiders point out the fact that the Indian cement industry is very proactive in adopting new technologies that provides it with a huge advantage over competition. Sunil Potdar, Managing Director, Schenck Process Solutions India Pvt Ltd, said, "From our perspective, cement plants in India are run very efficiently and that happens by virtue of the entrepreneurs being technically very savvy, with a lot of them directly involved in technical decision making, which ultimately works to their benefit."
Observed Thomas C Dannemiller, CEO, SABIA, "India is key because it is next to China as the biggest market. India, if it chose to, could export cement. And India is the place where we could learn to stand up to China. In order to do that we need to modernise the Indian cement industry." He urged the industry to aggressively imbibe IT, big data analytics and artificial intelligence if it wanted to attain to the top spot.
At 67 per cent, the housing sector consumes the lion’s share of cement produced in the country. Infrastructure (13 per cent), commercial construction (11 per cent), and industrial construction (9 per cent), are the other major consumers of the commodity. Moreover, with an expenditure of around $427 billion, India is the fourth largest construction market globally. A joint report by KPMG and real estate body National Real Estate Development Council (NAREDCO) has said that the country would climb to the third spot by 2030.
According to the Indian Brand Equity Foundation (IBEF), a trust managed by the Department of Commerce, India’s leading 20 cement manufacturers account for almost 70 per cent of its total production. Interestingly, 188 large cement plants alone account for 97 per cent of the country’s total installed capacity, while 365 small plants account for the rest. Of these large cement plants, 77 are located in the states of Andhra Pradesh, Rajasthan and Tamil Nadu.
Foreign fund inflow for manufacturing of cement and gypsum products reached $5.24 billion between April 2000 and June 2017, reveals government data. The FDI inflows in cement and gypsum product sector increased significantly from $19.69 million during 2015-16 to $2130 million during 2016-17. Ready availability of raw materials and limestone makes the country further attractive to overseas investors.
Experts aver that in the coming years, India’s eastern states could drive the demand for cement. They also believe that over the next 10 years, India could become the main exporter of cement to developing economies.
Further, the impending growth holds an opportunity for homegrown equipment makers. Affirmed Mayank D Kamdar, Marketing Director, Lilanand Magnesites Pvt Ltd, "In terms of opportunities, as many new cement plants have come up, and several more are in the pipeline, this offers a good opportunity for refractory manufacturers to introduce more efficient products. Since China’s output has been declining internationally, it’s a good time for the Indian refractory manufactures to start exporting." He felt that the Indian equipment makers have the potential to become major global players.
Key challenges persist
In August 2017, tropical cyclone Hurricane Harvey resulted in production shutdowns at oil and gas refineries in the US, with in turn also hit pet coke supplies. Since several Indian cement firms rely on imported pet coke, they ended up paying more for it and this was reflected in their second quarter results for the 2017-18 fiscal. Moreover, cement manufacturers are apprehensive that if the present surge in global crude oil continues, it could result in further hardening of pet coke prices. Some manufacturers had to shell out more towards raw material costs after a sharp increase in slag prices. Meanwhile, freight costs have also risen due to higher diesel prices.
In October last year, the Supreme Court banned use of pet coke and furnace oil in Uttar Pradesh, Haryana and Rajasthan in view of the spike in pollution levels in the National Capital Region (NCR). However, in December, the apex court gave relief to industries like cement, lime stone and thermal power plants by permitting the federal government to modify the ban notification. The court also asked states and union territories to consider a ban on pet coke.
Reacting to the calls an embargo on pet coke use, Saxena said, "Refineries within Indian and world over generate huge quantities of pet coke and other waste materials. The cement industry has upgraded technology and its operational skills to utilise even the low volatile content pet coke with several benefits. There is a substantial saving in coal consumption as it is directly substituted by pet coke." He added that because of the low ash content in pet coke, the cement industry could utilise low grade limestone. Similarly, the fear that that pet coke burnt in boilers releases lot of sulphur into the atmosphere, was unfounded as the intrinsic chemistry of the process ensured that a substantial portion of the sulphur present in pet coke reacted with the calcium carbonate content of the limestone to convert it into calcium sulfate or gypsum. "As for the release of sulphur dioxide, there are wet scrubber and other technologies available to take care of the emission," said Saxena.
Adequate utilisation of AFRM is another challenger before the industry. Speaking to the magazine on the sidelines of the event, Ashok Kumar Dembla, President and Managing Director, Customer Service Center India, KHD Humboldt Wedag International, strongly recommended that materials such as stubble burnt by farmers in large parts of Punjab and Haryana could instead be used as fuel in cement kilns with proper regulatory support. Similarly, preparation of municipal and chemical waste could also go a long way in reducing the industry’s dependence on coal. "Several European countries use 60 per cent of waste materials as fuel. But in India, on an average, it is not more than 10 per cent. There are bottlenecks in terms of handling, government support and interest from entities that generate waste," rued Dembla.
But using AFRM requires manufacturers to put appropriate systems in place. Advised Sunil Kumbhar, Manager Projects, ATS Conveyors India Pvt Ltd, "Cement manufacturers want an assured supply of fuel. However, since you cannot rely on a single source if you are using AFRM, one must be flexible about accepting all alternatives and prepare the cement plant accordingly."
Stakeholders point out that despite the government giving certain relaxation to cement manufacturers on environmental guidelines, they were presently in a quandary on the level of expenditure they could incur on their expansion plans, even while incorporating the best possible environment-friendly technologies. "They are also trying to convince the government to move slowly while implementing stringent environmental norms, because they are facing problems of higher production costs and improving overall sales," said Dembla.
Due to the increasing demand in various sectors, the Indian cement industry is expected to reach 550-600 million tonnes per annum (MTPA) by the year 2025. But industry insiders believe that with restoration of the growth momentum in the economy, the sector might do even better. Echoing this sentiment, Mogen Fons, Managing Director, FONS Technology, remarked, "For several years I’d been repeatedly telling myself that the Indian market will surely pick up the following year before I stopped doing that. Now I say that though the boom here won’t be like what we saw ten years ago in China, it is certainly coming!"

With the commissioning of the Chennai Drive Technology Centre, SEW-EURODRIVE India continues to strengthen its manufacturing footprint and reinforces its long-term commitment to supporting industrial growth and automation development in India.
We explore how material handling systems are becoming strategic assets in cement plants, enabling efficient movement of raw materials, clinker and finished cement. Advanced conveying, automation and digital technologies are improving plant productivity while supporting energy efficiency and sustainability goals.
Material handling systems form the operational backbone of cement plants, enabling the efficient movement of raw materials, clinker and finished cement across complex production networks. With India’s cement industry producing over 391 million tonnes of cement in FY2024 and possessing an installed capacity of around 668 mtpa, according to the CRISIL Research Industry Report, 2025, efficient material logistics have become critical to maintaining plant productivity and cost competitiveness. At the same time, cement production is highly energy intensive and contributes around 7 per cent to
8 per cent of global CO2 emissions, making efficient material flow and logistics optimisation essential for reducing operational inefficiencies and emissions states the International Energy Agency Cement Technology Roadmap, 2023. As plants scale capacity and integrate digital technologies, modern material handling systems, ranging from automated conveyors to intelligent stockyards, are increasingly recognised as strategic assets that influence plant stability, energy efficiency and environmental performance.
Strategic role of material handling
Material handling is no longer viewed as a secondary utility within cement plants; it is now recognised as a strategic system that directly influences production efficiency and process stability.
Cement manufacturing involves the continuous movement of large volumes of limestone, clay, additives, clinker and finished cement across multiple production stages. Even minor disruptions in conveying systems or storage infrastructure can lead to kiln feed fluctuations, production delays and significant financial losses. According to Indian Cement Industry Operational Benchmarking Study, 2024, unplanned downtime in large integrated cement plants can cost between Rs.15–20 lakh per hour, highlighting the economic importance of reliable material handling systems.
Modern cement plants are therefore investing in advanced mechanical handling systems designed for high throughput and operational reliability. Large integrated plants can process over 10,000 tonnes per day of clinker, requiring highly efficient conveying systems and automated stockyards to maintain continuous material flow, suggests the International Cement Review Industry Analysis, 2024. Efficient material handling also reduces spillage, minimises dust emissions and improves workplace safety. As cement plants become larger and more technologically advanced, the role of material handling is evolving from simple transport infrastructure to a critical operational system that supports both productivity and sustainability.
From quarry to plant
The transport of raw materials from quarry to processing plant represents one of the most energy-intensive stages of cement production. Traditionally, limestone and other raw materials were transported using diesel-powered trucks, which resulted in high fuel consumption, dust generation and increased operational costs. However, modern plants are increasingly adopting long-distance belt conveyors and pipe conveyors as a more efficient alternative. These systems allow continuous material transport over distances of 10–15 kilometres, significantly reducing fuel consumption and operating costs while improving environmental performance, states the FLSmidth Cement Industry Technology Report, 2024.
Milind Khangan, Marketing Manager, Vertex Market Research & Consulting, says, “Efficient and enclosed handling of fine materials such as cement, fly ash and slag requires modern pneumatic conveying systems. By optimising the air-to-material ratio, these systems can reduce energy consumption by 10 per cent to 15 per cent while ensuring smooth material flow. Closed-loop conveying further minimises dust loading and improves the performance of bag filters, supporting cleaner plant operations. In addition, flow-regulated conveying lines help prevent clogging and maintain reliable dispatch performance. Overall, automation in pneumatic conveying delivers immediate operational benefits, including improved equipment uptime, lower energy use, reduced material spillage and more stable kiln and mill performance.”
Pipe conveyor systems are particularly gaining traction because they provide a completely enclosed transport system that prevents material spillage and dust emissions. According to global cement engineering studies, conveyor-based transport can reduce energy consumption by up to 30 per cent compared to truck haulage, while also improving operational reliability. Several cement plants in India have already implemented such systems to stabilise quarry-to-plant logistics while reducing carbon emissions associated with diesel transport.
Stockyard management and homogenisation
Stockyards play a critical role in maintaining raw material consistency and stabilising kiln feed quality. Modern cement plants use advanced stacker and reclaimer systems to ensure efficient storage and blending of raw materials before they enter the grinding and pyroprocessing stages. Automated stacking methods such as chevron or windrow stacking enable uniform distribution of materials, while bridge-type or portal reclaimers ensure consistent extraction during kiln feed preparation. These systems are essential for maintaining stable chemical composition of raw meal, which directly influences kiln efficiency and clinker quality. The Cement Plant Operations Handbook, 2024 indicates that advanced homogenisation systems can reduce raw mix variability by up to 50 per cent, significantly improving kiln stability and energy efficiency. Integrated stockyard management systems also incorporate sensors for monitoring bulk density, moisture levels and stockpile volumes, enabling real-time control over material blending processes.
Clinker and cement conveying technologies
Once clinker is produced in the kiln, it must be efficiently transported to storage silos and subsequently to grinding and packing units. Modern cement plants rely on high-capacity belt conveyors, bucket elevators and pneumatic conveying systems to manage this stage of material flow. Steel-cord belt bucket elevators are now capable of lifting materials to heights exceeding 120 metres with capacities reaching 1,500 tonnes per hour, making them suitable for large-scale clinker production lines, states the European Cement Engineering Association Technical Paper, 2023.
For fine materials such as cement, fly ash and slag, pneumatic conveying systems provide a reliable and dust-free solution. These systems transport powdered materials using controlled airflow, ensuring enclosed and contamination-free movement between grinding units, silos and packing stations. Optimised pneumatic systems can reduce energy consumption by 10 per cent to 15 per cent compared to older conveying technologies, while also improving plant cleanliness and environmental compliance, according to the Global Cement Technology Review, 2024.
Automation and digitalisation
Digitalisation is transforming material handling systems by introducing real-time monitoring, predictive maintenance and automated control. Advanced sensors and Industrial Internet of Things (IIoT) platforms enable plant operators to track conveyor health, stockpile levels and equipment performance in real time. Predictive maintenance systems analyse vibration patterns, temperature fluctuations and equipment load data to detect potential failures before they occur. According to McKinsey’s Industry 4.0 Manufacturing Report, 2023, for heavy industries, digital monitoring and predictive maintenance technologies can reduce equipment downtime by up to 30 per cent and increase productivity by 10 per cent to 15 per cent. Digital control centres also integrate data from conveyors, stacker reclaimers and dispatch systems, enabling centralised management of material flows from quarry to dispatch.
Handling of AFR
The growing adoption of Alternative Fuels and Raw Materials (AFR) has introduced new challenges and opportunities for material handling systems in cement plants. AFR materials such as refuse-derived fuel (RDF), biomass and industrial waste often have irregular particle sizes, variable moisture content and lower bulk density compared to conventional fuels. As a result, specialised storage, dosing and feeding systems are required to ensure consistent kiln combustion. According to the Cement Sector Decarbonisation Roadmap published by NITI Aayog in 2026, increasing the use of AFR could enable India’s cement sector to achieve thermal substitution rates of around 20 per cent in the coming decades. To support this transition, plants are investing in automated receiving stations, shredding units, drying systems and precision dosing equipment to stabilise AFR supply and combustion performance.
Energy efficiency and dust control
Material handling systems also play a crucial role in improving plant energy efficiency and environmental performance. Modern conveyor systems equipped with variable speed drives and energy-efficient motors can significantly reduce electricity consumption. Permanent magnet motors used in conveyor drives can deliver 8 per cent to 12 per cent energy savings compared to conventional induction motors, improving overall plant energy efficiency according to the IEA Industrial Energy Efficiency Study, 2023. Dust control is another major concern in cement plants, particularly during material transfer and storage operations. Enclosed conveyors, dust extraction systems and advanced bag filters are widely used to minimise particulate emissions and improve workplace safety.
Future trends in material handling
The future of material handling in cement plants will be shaped by automation, digitalisation and sustainability considerations. Emerging technologies such as AI-driven logistics optimisation, autonomous mobile equipment and digital twins are expected to further improve plant efficiency and operational visibility. Digital twin models allow engineers to simulate material flow patterns, optimise stockyard operations and predict equipment performance under different operating conditions. According to the International Energy Agency Digitalisation and Energy Report, 2024, the adoption of advanced digital technologies could improve industrial energy efficiency by up to 20 per cent in heavy industries such as cement manufacturing. As cement plants expand capacity and adopt low-carbon technologies, intelligent material handling systems will play a critical role in maintaining productivity and reducing environmental impact.
Conclusion
Material handling systems have evolved from basic transport infrastructure into strategic operational systems that directly influence plant efficiency, reliability and sustainability. From quarry transport and automated stockyards to digital dispatch platforms and advanced conveying technologies, modern material handling solutions enable cement plants to manage large production volumes while maintaining process stability.
As India’s cement industry continues to expand to meet infrastructure and urban development demands, investments in advanced material handling technologies will become increasingly important. By integrating automation, digital monitoring and energy-efficient systems, cement manufacturers can improve operational performance while supporting the industry’s long-term sustainability and decarbonisation goals.

Cement plant modernisation is reshaping the industry through upgrades in
kilns, energy systems, digitalisation, AFR integration and advanced material
handling. We explore these technologies that improve efficiency, reduce
emissions, strengthen competitiveness, while preparing the industry for India’s
next phase of infrastructure growth.
India’s cement industry, the world’s second-largest, is undergoing a rapid transformation driven by infrastructure demand, decarbonisation targets and technological advancement. The sector’s installed capacity stood at approximately 668 million tonnes per annum (mtpa) in FY2025 and is projected to reach 915–925 mtap by 2030, supported by large-scale capacity expansions and infrastructure investment cycles, suggests CRISIL Intelligence Industry Report, 2025. At the same time, cement production remains highly energy intensive and contributes about 6 per cent to 7 per cent of India’s total greenhouse gas emissions, making efficiency improvements and modernisation critical for long-term sustainability as stated in CareEdge ESG Research, 2025. As a result, cement manufacturers are investing in advanced kiln technologies, digital monitoring systems, waste heat recovery, alternative fuels, and modern material handling infrastructure to enhance productivity while aligning with global decarbonisation pathways.
Need for modernisation
The need for plant modernisation is closely linked to the sector’s rapid capacity expansion and rising operational complexity. India’s installed cement capacity has grown significantly in the last decade and is expected to exceed 900 mtpa by 2030, driven by demand from housing, infrastructure and urban development projects, as per the CRISIL Intelligence Industry Report, 2025. However, increasing scale also places pressure on energy efficiency, logistics, and production stability. The report also suggests that the cement plants must upgrade equipment and processes to operate at higher utilisation rates, which are projected to reach 75 per cent to 77 per cent by the end of the decade, compared to around 72 per cent to 74 per cent in FY2026.
Environmental imperatives are another major driver of modernisation. Cement manufacturing is responsible for a significant share of industrial emissions because clinker production requires high-temperature processes that depend heavily on fossil fuels. According to CareEdge ESG research, the cement sector contributes 6–7 per cent of India’s total greenhouse gas emissions, with approximately 97 per cent of emissions arising from direct fuel combustion and process emissions in kilns. Consequently, plant modernisation initiatives now focus not only on productivity improvements but also on reducing emissions intensity, energy consumption, and reliance on conventional fuels.
“One of the most impactful upgrades implemented at Shree Cement in the last five years has been the adoption of advanced data management platforms that provide real-time visibility across major process areas. This digital advancement has strengthened plant automation by enabling faster and more accurate responses to process variations while improving the reliability of control loops. Real-time dashboards, integrated analytics and automated alerts now support quicker, data-driven decision-making, helping optimise kiln and mill performance, improve energy control and detect deviations early. By consolidating data from multiple systems into a unified digital environment, the company has enhanced operational consistency, reduced downtime and improved both productivity and compliance. This shift towards intelligent automation and real-time data management has become a key driver of operational excellence and future-ready plant management,” says Satish Maheshwari, Chief Manufacturing Officer, Shree Cement.
Kiln and pyroprocessing upgradation
The kiln remains the technological heart of cement manufacturing, and modernisation efforts often begin with upgrades to pyroprocessing systems. Many older plants in India operate with four- or five-stage preheaters, while modern plants increasingly adopt six-stage preheater and pre-calciner systems that significantly improve heat efficiency and clinker output. These systems enhance heat transfer, reduce fuel consumption, and stabilise kiln operations under high throughput conditions.
Professor Procyon Mukherjee suggests, “Cement manufacturing is, at its core, a thermal process. The rotary kiln and calciner together account for energy consumption and emissions. The theoretical thermal requirement for clinker production is around 1700–1800 MJ per tonne, yet real-world plants often operate far above this benchmark due to inefficiencies in combustion, heat recovery and material flow. Modernisation, therefore, must begin with the
kiln system, and not peripheral automation or
isolated upgrades. The shift from wet to dry process kilns, combined with multi-stage preheaters and precalciners, has already delivered step-change improvements, making dry kilns nearly 50 per cent more energy efficient.”
Recent investment programmes across the industry have included kiln cooler upgrades, advanced burners, and improved refractory materials designed to increase operational reliability and reduce specific heat consumption. Such upgrades are essential because cement production remains highly energy intensive, and continuous efficiency improvements are required to meet global decarbonisation targets. According to the International Energy Agency (IEA) Cement Tracking Report, 2023, the cement sector must achieve annual emissions intensity reductions of around 4 per cent through 2030 to align with global net-zero scenarios.
Energy efficiency and WHRS
Energy efficiency remains one of the most important areas of modernisation in cement manufacturing, given the sector’s heavy reliance on thermal and electrical energy. Modern plants deploy advanced process controls, efficient grinding systems, and improved combustion technologies to reduce specific energy consumption. The adoption of energy-efficient technologies is particularly important in India, where energy costs account for a large share of production expenses. As demand grows and plants expand capacity, improving energy performance becomes essential to maintain competitiveness.
Waste Heat Recovery Systems (WHRS) have emerged as a key solution for improving plant energy efficiency. During cement production, large volumes of high-temperature gases are released from kilns and coolers. WHRS technology captures this waste heat and converts it into electricity, thereby reducing reliance on external power sources. According to energy benchmarking studies for the Indian cement industry, installed waste heat recovery capacity in the sector has reached approximately 840 MW, with an additional potential of around 500 MW states the Green Business Centre, Energy Benchmarking Report, 2023. Several leading producers have already implemented large WHRS installations; for example, UltraTech Cement has deployed systems with around 121 MW of waste heat recovery capacity, reducing carbon emissions by nearly 0.5 million tonnes annually according to the Energy Alternatives India Case Study, 2024.
Integration of AFR
The integration of Alternative Fuels and Raw Materials (AFR) is another critical dimension of cement plant modernisation. AFR refers to the use of industrial waste, biomass, refuse-derived fuel (RDF), and other non-fossil materials as substitutes for conventional fuels such as coal and petcoke. Increasing the use of AFR helps reduce fossil fuel consumption while simultaneously addressing waste management challenges. According to the NITI Aayog Decarbonisation Roadmap, 2026, scaling the use of RDF and other alternative fuels could enable the sector to achieve thermal substitution rates of around 20 per cent in the coming decades.
However, integrating AFR requires significant plant modifications and operational adjustments. Waste-derived fuels often have inconsistent calorific values, higher moisture content, and heterogeneous physical properties compared to traditional fuels. As a result, modern plants invest in advanced fuel preparation systems, dedicated feeding equipment, and automated dosing technologies to ensure stable kiln operation. These upgrades allow plants to maintain consistent clinker quality while increasing the share of alternative fuels in their energy mix.
Digitalisation and smart plant operations
Digitalisation is rapidly transforming cement plant operations by enabling data-driven decision-making and predictive maintenance. Industry 4.0 technologies such as IoT sensors, artificial intelligence (AI), and advanced analytics are now used to monitor equipment performance, optimise process parameters, and anticipate maintenance requirements. These digital tools enable plant operators to detect early signs of equipment failure, minimise unplanned downtime, and improve operational efficiency. Predictive maintenance systems, for example, analyse vibration, temperature, and acoustic signals from rotating equipment to identify potential faults
before they escalate into major breakdowns. Digital twins and integrated control systems further allow operators to simulate plant performance under different scenarios and optimise production strategies. Such technologies are becoming increasingly important as cement plants operate at larger scales and higher levels of process complexity.
Maheshwari also adds, “Plant modernisation is also increasingly central to the global competitiveness of Indian cement manufacturers. As cost pressures rise across energy, logistics and regulatory compliance, modern plants offer the structural efficiency required to operate reliably and competitively over the long term. Technologies such as AI-driven Advanced Process Control (APC) integrated with real-time data systems are emerging as essential investments for the future. These platforms use predictive algorithms, machine learning and live process inputs to optimise kiln, mill and utility operations with greater precision than traditional control systems. By continuously analysing variations in feed chemistry, temperature profiles, energy demand and equipment behaviour, APC enables stable operations, lower specific energy consumption, reduced emissions and improved product consistency. As regulatory expectations tighten and plants pursue higher efficiency with lower carbon intensity, AI-enabled APC will play a crucial role in strengthening automation, enhancing decision-making and ensuring long-term operational resilience.”
Modern material handling and logistics
Material handling systems play a critical role in ensuring smooth plant operations and efficient logistics. Modern cement plants rely on advanced conveying systems, automated stockyards, and digital dispatch platforms to manage the movement of raw materials, clinker, and finished cement. Long-distance belt conveyors and pipe conveyors are increasingly replacing truck-based transport between quarries and plants, reducing fuel consumption, dust emissions, and operational costs. Automated stacker-reclaimers ensure consistent blending of raw materials,
which improves kiln stability and clinker quality. Meanwhile, advanced packing and dispatch systems equipped with high-speed rotary packers and robotic palletisers enhance throughput and reduce manual labour. These technologies allow cement plants to optimise logistics efficiency while supporting higher production capacities.
Emission control and environmental compliance
Environmental compliance has become a central focus of cement plant modernisation as regulators and investors place greater emphasis on sustainability performance. Modern plants deploy advanced emission control technologies such as high-efficiency bag filters, electrostatic precipitators, and selective non-catalytic reduction systems to reduce particulate matter and nitrogen oxide emissions.
Sine Bogh Skaarup, Vice President, Head of Green Innovation and R&D, Fuller Technologies says, “One of our key focus areas is decarbonisation. We help cement producers reduce CO2 and overall carbon emissions. We offer alternative fuel solutions and calcined clay technologies to enable the production of LC3 cement, which play a significant role in decarbonising the cement industry. By combining alternative fuels and calcined clay solutions, CO2 emissions can be reduced by up to 50 per cent, making this a highly impactful approach for sustainable cement production.”
Continuous emission monitoring systems are increasingly used to track environmental performance in real time and ensure compliance with regulatory standards. In addition to air pollution control, cement companies are also investing in water recycling systems, renewable energy integration, and carbon reduction initiatives. These measures are essential for aligning the sector with national climate goals and improving the environmental footprint of
cement manufacturing.
Economic benefits and future outlook
Beyond environmental and operational advantages, cement plant modernisation also delivers significant economic benefits. Energy efficiency improvements, digital process optimisation, and advanced material handling systems reduce operating costs and improve asset utilisation. Waste heat recovery and alternative fuels help lower fuel expenditure and reduce exposure to volatile fossil fuel markets. As the industry expands capacity to meet growing demand, modernised plants are better positioned to achieve higher productivity and maintain profitability. The long-term outlook for the sector remains positive, with India expected to continue large-scale infrastructure investments in roads, housing, railways, and urban development.
Milan R Trivedi, Vice President – Projects, Prod & QC, MR, Shree Digvijay Cement, says, “The main focus in case of modernisation projects drives through the investment decision, which is mainly based on IRR and impact on overall efficiency improvement, cost optimisation and improvement in reliability. However, there are certain modernisation, which has high impact on environmental impact, statutory requirements, etc. has higher priority irrespective of ROI or payback period.”
“The energy efficiency and reliability investment projects generally provide fast return on investment whereas strategic, digitalisation and environmental investment projects provide long term and compounded benefits. Typical modernisation investment projects are decided with IRR of about > 20 per cent, payback period of typically 2-3 years for fast-track projects,” he adds.
In this context, modernisation will remain a key strategic priority for cement manufacturers seeking to maintain competitiveness in an increasingly sustainability-focused market.
Conclusion
The modernisation of cement plants is no longer a purely technical upgrade but a strategic transformation that reshapes how the industry operates. As India’s cement sector expands capacity toward the next growth cycle, improvements in energy efficiency, digitalisation, alternative fuels and advanced logistics will determine the competitiveness of individual plants. Modern technologies allow producers to operate at higher productivity levels while simultaneously reducing energy consumption and emissions intensity.
Looking ahead, the pace of technological adoption will play a decisive role in shaping the future of
the cement industry. Companies that successfully integrate modern equipment, digital systems, and sustainable production practices will be better positioned to meet rising infrastructure demand while aligning with global climate commitments. In this evolving landscape, plant modernisation stands as the cornerstone of both operational excellence and environmental responsibility.
