The organised segment continues to focus on innovative special concrete, quality and timely delivery, while the unorganised players tend to reduce the operating costs by lower compliances tax evasions and employing unskilled labour at cheaper costs, says Atul Desai.

The construction industry is having a significant role in the India’s development and it contributes about 8-10 per cent to GDP on an average. Developing nations like India need to have faster construction with high quality, durability and a pollution-free environment, which can be achieved only with ready-mix concrete (RMC).

Market size
Overall economic slowdown impacted commercial and industrial construction combined with sluggish residential real estate activity and resulted in moderate rise in RMC market at a CAGR of 4-5 per cent to reach an estimated Rs 215 billion (58 million cubic meters) in 2015-16 from Rs 184 billion (50 million cubic meters) in 2012-13. This growth is anticipated to increase to 6-8 per cent CAGR touching close to 300 billion (81 million cubic meters) by 2020-21. The growth in RMC demand may be primarily attributed to government-infused spending in infrastructure and expected demand from affordable housing.

Growth trends & future projections
Real estate currently accounts for 60-65 per cent of RMC consumption with residential real estate occupying the majority share (38-42 per cent). Further while infrastructure constitutes about 32-35 per cent of RMC demand, industrial and commercial construction constituted about 26-28 per cent of the total RMC consumption in 2016-17.

RMC penetration, measured as the proportion of cement consumed in commercial RMC to total cement consumption in India, is expected to increase to 10 per cent by 2020-21 from the current 7 per cent on the back of healthy demand growth, increased usage in infrastructure projects and penetration of RMC plants in tier-II/ tier-III cities, consistent quality requirements, stringent project timeline, and higher focus on safety and quality norms amongst others. RMC penetration in India has gradually risen with increasing acceptability and usage of higher grade of concrete; however, the current levels are very low compared to other developed economies such as USA, Europe and China where it is above 65-70 per cent.

Southwest, India is anticipated to continue to grow faster than rest of India and is expected to contribute close to 70 per cent of total growth of RMC. North and East may have stable growth and their contribution to RMC growth is only 10 per cent, which may remain more or less range bound till 2020-21.

The biggest demand drivers for the country’s RMC and batching plant segments will be the Indian Government’s large-scale infrastructure and housing for all scheme. These infrastructure projects include the Bharatmala Pariyojana, Sagarmala, the Smart Cities Mission and the Pradhan Mantri Awas Yojana, and Affordable housing. The Government initiatives on the dedicated freight corridors have also provided opportunities for setting up new RMC plants across the country. With rapid urbanisation, the Indian construction industry has witnessed a major move towards complex architectural structures in commercial buildings, elevated driveways, coastal highways, bullet trains, etc., which may further fuel the demand for high performance concrete.

National capacities & regional/metro capacities
The cumulative current RMC capacity is estimated at about 60,000 cu.m/hr with a relatively comparative spread of commercial and dedicated batching plants across India. RMC demand also has increased at a CAGR of 4-5 per cent. However, owing to inadequate awareness and soft government norms, conversion from site mix is at a very negligible pace especially in small towns and rural areas.

Mumbai and Delhi alone constitute close to 45-50 per cent of total consumption in West and North respectively whereas, Bengaluru and Hyderabad put together constitute about 45 per cent of total consumption in South.

Going further, tier-II and tier-III cities may catch up soon, and the concentration of capacities is expected to gradually rise in such cities too.

Hotspots of growth
Key demand centres of western and southern regions are the most favourable markets for RMC business. Mumbai, Nagpur from West and Chennai, Hyderabad and Amravati from southern region are among the top ranked cities for RMC business attractiveness.

Mumbai leads the city-wise attractiveness list. Construction of multiple metro rail corridors, coastal road, trans harbour sea link and Mumbai-Nagpur Expressway to name a few may spurt RMC demand.

Challenges for growth
Site mix is still prominent due to lack of awareness and lack of focus on quality control and quality assurance – grey areas neglected by the Government authorities.
Capacity utilisation continues to remain low across regions due to restricted traffic hours, limited hours of functioning, stringent regulatory norms and diverse nature of business.
Low capex encourages growth of unorganised players, a segment which is yet to professionalise this business in the right direction.
Availability of consistent quality raw materials.
Increasing credit exposure to the real estate segment, which is under stress due to drop in sales and liquidity crunch is a major concern.

Issues at hand
Deterioration in quality due to site mix.
Limited supply of consistent quality river sand and availability of aggregate nearer to major city.
Freshly-made RMC needs to be placed or used in a fixed time frame, but transportation is a constraint due to huge traffic congestion and entry restrictions in city.
The perishable nature of RMC necessitates the need for the RMC batching plant to be located near construction sites. However, the setting up of commercial plants in metro cities is a challenge due to space constraints as there is no designated zone for RMC units,
Output is restrained due to reduction of working hours – no night work is entertained in residential zones.
Unrealistic short duration and multi-layer Government approvals lead to uncertainty of the plant locations.
Increase in credit exposure to real estate segment has led to huge working capital requirements.
Limited existence of product differentiation and less technological know-how due to spurt in local players is also a significant issue.
Unethical practices by local players.

Outward transport: 12-15 per cent (Unpredictable oil prices, which are directly linked to global crude oil prices are as well increase the cost.)
Power: 2-3 per cent
Wages: 7-8 per cent
Other overheads: 4-6 per cent
Cost due to high working capital because of huge credit exposure to real estate developer segment
Operating margins: 3-6 per cent
The organised segment continues to focus on innovative special concrete, quality and timely delivery. The segment is thus marred with high operating cost owing to high overheads and expenses, which are incurred on training, safety, technology, continuous R&D, QA/QC and testing to bring about transparency in the process. Huge credit exposure also carries significant cost.
The unorganised players, on other hand, tend to reduce the operating costs by lower compliances tax evasions and employing unskilled labour at cheaper costs, overlooking safety/quality norms with minimal upkeep and maintenance of the batching plant.

Crucial differentiators
RMC is operated in the local market, but provides global solutions, which are a real differentiator.
Quality and customised concrete suitable for each application, combined with speed at optimum cost differentiates RMC with site mix.
RMC being a service oriented industry; timely reach to the customer is significant.
Quality authorised labs affiliated to recognised professional bodies to ensure quality assurance and control.

Cement downstreams v/s standalone players
RMC is a local business, provides global solutions.
Its more construction service oriented business and hence may be seen as standalone business.
RMC provides opportunity to cement companies to understand the customer closely, thereby avoiding commercialisation of cement.
Various options of cement are available.
RMC may also offer aggregate crushers opportunity to ride on value chain, locking the customers.
Pragmatically, since local flavour is more prominent and a lot of options w.r.t cement are available, standalone plants preferably supported by aggregate supply back up may be desired.

Organised v/s unorganised players
Majority forward integrated players with nation-wide business reach constitute organised segment. They have large operational setups with huge capacities in anticipation of meeting the long-term demand. The product offerings are application based superior ones and they maintain highest safety standards. Their labs are usually certified by professional bodies like BIS/QCI/NABL and are well equipped. Continuous R&D is part and parcel of business, resulting in to new product developments and implementation of out-of-box innovations. Driven by professionalism, lots of focus is on training and development of the team.

Whereas, unorganised players are the local standalone one, who caters to regional demand with smaller capacities thriving on moderate profitability. Prices are generally lower and product offerings are standard replicated ones. Desired standards and quality are rarely implemented. Safety is a big concern. Grades widely used are replicated and on-the-job training is usually carried out.

Impact of demonetisation
Demonetisation had majorly hit residential real estate construction, which is characterised by large cash transactions. Furthermore, demonetisation also severely impacted unorganised players thriving on tax evasion and cash payments.

Impact of GST
Cement will attract 28% GST resulting in increased costs for the infrastructure sector. GST in India was a dream to reform various area of economy and taxation system. Implementation of GST has benefitted organised players as the same has brought about transparency in dealings.

Recommendations to the Government
Construction industry in India is in developing stage and the role of Government in bringing about changes is very significant as many areas need complete revamping. A few suggestions relevant suggestions are below mentioned:

Stringent and well-defined QA/QC and safety norms need to be laid down by the Government, which discourages and completely abolishes usage of site mix.
RMC being environment-friendly and pollution-free industry, the Government must enforce usage of RMC at all levels and ban site mix.
RMC being a green industry needs to have designated zones for setting up plants in major cities with long term approval of 10 years to reduce establishment cost.
Long terms single-window approvals from the Government, avoiding multiple agencies for ease-in-business and sustainability is expected.
Value concrete and environment-friendly solutions like UTWT for roads, Dyecrete for pavements and perviouscrete to avoid water logging may be recommended or even made mandatory as the case be.
To avoid accidents and have a safe ride, paver blocks need to be banned and better alternative solutions like Dyecrete?stamped concrete need to be specified.
Solution to traffic restrictions need to be worked out and permission to transport through transit mixers 24×7 should be allowed.
Quality authorisation from BIS/QCI should be mandatory not only for prequalification and tenders, but also for small sites.
Sops may be considered for encouraging RMC industry towards its valuable contribution by becoming environment friendly in "go green" concept utilising fly ash and GGBS.

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.

Modernise to Optimise

Published

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.
