As India’s cement industry heads for unprecedented growth, the importance of smart, sustainable and strategic lubrication is gaining ground. From reducing downtime and enhancing energy efficiency to enabling predictive maintenance, lubricants are transforming plant performance. ICR explores how advanced lubrication solutions are becoming critical enablers of reliability, resilience and environmental stewardship in the cement sector.

The Indian cement industry, a cornerstone of the nation’s infrastructure development, is experiencing significant growth. In 2023, India’s cement production reached 374.55 million tonnes, marking a 6.83 per cent year-on-year growth. Projections indicate that the market size will expand from 3.96 billion tonnes in 2023 to 5.99 billion tonnes by 2032, reflecting a compound annual growth rate (CAGR) of 4.7 per cent during 2024-32. This expansion underscores the increasing demand for efficient and sustainable operations within the sector.
In cement manufacturing, equipment such as kilns, crushers, vertical mills, ball mills, conveyors and fans operate under extreme temperatures, heavy loads and high dust exposure. These demanding conditions make proper lubrication not just essential, but mission-critical. Selecting the right type of lubricant and maintaining an effective lubrication regime can drastically improve machine uptime, reduce maintenance costs, and enhance plant safety. In many cases, lubricant-related failures account for a significant proportion of unplanned downtime, underscoring the value of a well-structured lubrication strategy.
The Indian cement sector is also undergoing a technological transformation, with increasing emphasis on automation, predictive maintenance and energy efficiency. In this evolving landscape, lubricants are no longer just consumables—they are enablers of performance, longevity and sustainability. With the growing availability of advanced lubricants and condition-monitoring technologies, Indian cement plants have the opportunity to optimise their lubrication practices in line with global standards. Additionally, tightening environmental regulations and sustainability goals are driving the shift toward eco-friendly lubricants and responsible usage practices, making lubrication management a key factor in both operational and environmental performance.
As the industry moves forward, there is a growing realisation that lubrication excellence can be a competitive differentiator. This article explores the critical role of lubricants in cement manufacturing, the latest technological advancements, the environmental considerations shaping lubricant use, and the challenges and opportunities for cement producers in India aiming to maximise equipment reliability and operational efficiency.

The role of lubricants in cement manufacturing
Cement manufacturing involves heavy-duty machinery operating under extreme conditions—high temperatures, heavy loads and continuous operations. Lubricants are essential in minimising friction, reducing wear and tear, and preventing equipment failures. Proper lubrication ensures that components such as kilns, crushers and grinding mills function optimally, thereby reducing downtime and maintenance costs.
Moreover, the integration of advanced lubrication technologies has enabled predictive maintenance strategies. By monitoring lubricant conditions, operators can anticipate equipment issues before they escalate, allowing for timely interventions and uninterrupted production cycles.
“Lubricants play a crucial role in enhancing the efficiency and reliability of cement plant operations. High-performance lubricants reduce friction and wear in critical machinery such as crushers, kilns, mills, and conveyors, ensuring smoother operation and extending equipment life. By minimising mechanical breakdowns and unplanned downtime, they contribute to consistent production and lower maintenance costs. Additionally, specialised lubricants designed to withstand high temperatures, heavy loads, and dusty environments help maintain optimal performance under demanding conditions. Proper lubrication also improves energy efficiency by reducing power loss due to friction. In essence, the right lubrication strategy not only enhances equipment reliability and operational uptime but also supports overall cost-effectiveness and productivity in cement manufacturing,” says Hiten Ved, Sales Head, Royal Petro Specialities.
In addition to enhancing equipment longevity, lubricants are pivotal in ensuring uninterrupted production cycles. Cement manufacturing is a 24/7 operation, and any unexpected downtime due to mechanical failure can lead to significant financial losses. Lubricants with high thermal stability and oxidation resistance prevent the breakdown of oil films under intense heat, especially in applications like rotary kilns, vertical roller mills and clinker coolers. By reducing the likelihood of equipment seizures or breakdowns, these lubricants act as silent enablers of plant reliability and uptime.
Gaurav Mathur, Director and Chief Executive Officer, Global Technical Services, says, “Wall paintings in tombs show workers using water to move statues, indicating early recognition of lubrication. By 1400 BC, animal fat was used to lubricate chariot axles, ever since then mankind has been relentlessly working to improvise the efficiency of lubricants. Tribological advancements have propelled industrialisation in the world. Machines working in demanding environment need better performance, however merely just better lubricant that is made from highly refined base oils is not good enough. Mineral and synthetic base oils and advanced additives chemistry have given birth to advanced lubricants. These lubricants have better performance characteristics and longer service life.”
“However, the way lubrication is done is more critical and if lubrication is not performed in a proper way, highest performing lubricants would also under perform compared to the lowest specification product. Total Lubrication Management has to be implemented for better machine reliability, equipment availability and lower down time. Implementation of TLM has paid rich dividends in the industry. Pillars of TLM being, contamination free lubrication, regular testing of lubricants to access the lubricant and machine condition and regeneration of lubricants,” he adds.
Lubricants contribute directly to energy efficiency. Friction losses within rotating equipment can account for up to 30 per cent of the total energy consumption in certain plant areas. Advanced synthetic lubricants, with low traction coefficients and superior film strength, reduce this internal resistance, thus improving mechanical efficiency and lowering the plant’s overall energy footprint. As Indian cement plants pursue energy benchmarking and ISO 50001 certifications, the use of high-performance lubricants becomes an integral strategy in achieving energy conservation goals.
“The cement industry has many lubrication points that require NLGI Grade 2 grease that can be used in high temperature applications. These may include bearings on vibrating screens and roller mills; rotating joints on grinding units; and various shafts, pivots, and metal to metal contact points found throughout the plant. CorrLube™ VpCI® Lithium EP Grease has a dropping point of 360 °F (182 °C), allowing it to be used in a broad range of temperatures. For areas that need a slightly harder grease of NLGI Grade 3, EcoLine® Biobased Grease offers a
similar dropping point of 365 °F (185 °C), explain Julie Holmquist, Marketing Content Writer,
Cortec Corporation.

Market dynamics: growth and trends
The Indian industrial lubricants market was valued at $13.05 billion in 2024 and is projected to reach $ 20.72 billion by 2033, growing at a CAGR of 4.12 per cent. This growth is driven by the expanding industrial sector, increased mechanisation, and the adoption of advanced machinery requiring specialised lubricants.
In the cement sector specifically, the demand for high-performance lubricants is rising. The lubricants for cement market are estimated to be $ 2.5 billion in 2024 and is expected to reach $ 3.9 billion by 2033, at a CAGR of 5.3 per cent from 2026 to 2033. This surge is attributed to the need for lubricants that can withstand harsh operating conditions and enhance equipment reliability.

Advancements in lubrication technology
Recent years have witnessed significant advancements in lubrication technology tailored for the cement industry. Synthetic lubricants, known for their superior thermal stability and longer service life, are increasingly being adopted. These lubricants perform effectively under extreme temperatures and heavy loads, common in cement manufacturing processes.
Additionally, the development of bio-based lubricants offers environmentally friendly alternatives without compromising performance. These lubricants, derived from renewable sources, reduce the environmental footprint and align with global sustainability goals. Their biodegradability and low toxicity make them suitable for applications where environmental considerations are paramount.
Smart lubrication systems are another breakthrough in the cement industry. These systems use IoT-enabled sensors and controllers to monitor lubricant condition in real time—tracking parameters such as viscosity, temperature, contamination levels and usage. This data is integrated into plant maintenance software to automate lubricant replenishment and alert operators to potential failures. Predictive lubrication ensures that each component receives the right amount of lubricant at the right time, minimising waste, reducing manual intervention, and extending machinery life.
“Many VpCI® products can be applied to surfaces with minimal pre-cleaning, and the protective VpCI® layer typically does not need to be removed before equipment is put back into service. VpCI® ‘s save significant labor, time, and associated costs compared to methods that require extensive surface preparation (e.g., sandblasting) and post-application cleaning or degreasing. This allows for faster startup after maintenance,” elaborates Ana Juraga, Content Writer, Cortec Corporation.
Furthermore, Original Equipment Manufacturers (OEMs) and lubricant suppliers are collaborating to develop application-specific lubricants tailored to the unique operating conditions of cement manufacturing units. For example, gear oils designed for high-load kilns or open gear systems now come with superior Extreme Pressure (EP) additives and anti-wear properties to cope with shock loading and variable speed operations. These co-developed solutions not only enhance mechanical reliability but also ensure compatibility with diverse materials used in modern cement equipment, ensuring peak performance in both greenfield and brownfield plants.

Sustainability and environmental considerations
The cement industry is under increasing pressure to reduce its environmental impact. Lubricants contribute to this goal by enhancing energy efficiency and reducing emissions. High-quality lubricants decrease friction, leading to lower energy consumption and, consequently, reduced greenhouse gas emissions.
Furthermore, the use of long-life lubricants minimises the frequency of oil changes, thereby reducing waste generation and disposal issues. The shift towards bio-based and recyclable lubricants also supports circular economy principles, promoting resource efficiency and environmental stewardship.
A report by Klüber Lubrication India suggests that sustainability continues to be a key focus for industries, the Securities and Exchange Board of India (SEBI) has mandated Business Responsibility and Sustainability Reporting (BRSR) for the top 1,000 listed companies. This framework requires organisations to disclose their environmental, social and governance (ESG) initiatives, including energy conservation, emission reductions and resource optimisation. Beyond compliance, BRSR reporting allows companies to showcase their sustainability leadership and build investor confidence. Organisations that proactively address sustainability challenges are better positioned to attract long-term investors, secure financing, and maintain a competitive advantage in an evolving regulatory landscape.
The report also states that their high-performance synthetic lubricants play a crucial role in helping cement manufacturers meet these regulatory requirements by enhancing energy efficiency and reducing CO2 emissions in critical machinery such as vertical roller mills (VRMs) and main gearboxes. By adopting our energy-efficient solutions, companies can strengthen their BRSR compliance while achieving tangible operational benefits.
An emerging trend in the lubricant industry is the formulation of biodegradable lubricants specifically tailored for heavy industries like cement manufacturing. These eco-friendly alternatives are made from renewable base stocks and are designed to degrade naturally without leaving behind harmful residues. In environmentally sensitive zones or operations with high spill risk, such as open gear applications or hydraulic systems exposed to the elements, biodegradable lubricants offer a sustainable solution that aligns with stricter environmental regulations and the growing emphasis on corporate social responsibility (CSR) in India’s industrial sector.
KB Mathur, Founder and Director, Global Technical Services, says, “In the world of industrial machinery, lubricating oils while essential; are often misunderstood in terms of their life cycle. When oils are used in machinery, they don’t simply ‘DIE’. Instead, they become contaminated with moisture (water) and solid contaminants like dust, dirt and wear debris. These contaminants degrade the oil’s effectiveness but do not render it completely unusable. Used lubricants can be regenerated via advanced filtration processes/systems and recharged with the use of performance enhancing additives hence restoring them. These oils are brought back to ‘As-New’ levels. This new fresher lubricating oil is formulated to carry out its specific job providing heightened lubrication and reliable performance of the assets with a view of improved machine condition. Hence, contributing to not just cost savings but leading to magnified productivity, and diminished environmental stress.”
Lubricant manufacturers are increasingly focusing on circular economy principles, offering oil analysis, filtration and recycling services that extend lubricant life and minimise waste. Used oil regeneration programs not only reduce disposal costs but also help cement plants meet regulatory norms under the Hazardous Waste Management Rules of India. This closed-loop approach not only lowers the environmental burden but also enhances economic efficiency—making sustainability a dual benefit for operational and ecological performance. As cement companies work towards science-based targets and carbon neutrality, lubricant selection and management play a more strategic role in meeting these broader sustainability commitments.

Challenges and opportunities
Despite the benefits, the adoption of advanced lubricants in the Indian cement industry faces challenges. These include the higher initial costs of synthetic and bio-based lubricants and a lack of awareness about their long-term benefits. Additionally, the integration of lubrication management systems requires investment in training and infrastructure.
However, these challenges present opportunities for innovation and collaboration. Manufacturers
can work closely with lubricant suppliers to develop customised solutions that meet specific operational needs. Moreover, government incentives and regulatory frameworks promoting sustainable practices can accelerate the adoption of advanced lubrication technologies.
Another key challenge is the limited awareness and technical training available at the plant level regarding proper lubrication practices. Many maintenance teams still rely on outdated methods such as manual greasing or fixed-interval lubrication schedules, which often lead to over-lubrication, under-lubrication or lubricant contamination. This results in premature equipment wear and higher operating costs. There is a growing need for skill development programmes and collaboration with lubricant suppliers to train technicians on best practices, condition-based monitoring, and the use of smart lubrication systems.
“Oil in the machine is like blood in the human body. There is no rotating machine that works without lubricants (liquid, semi liquid or solid). Based on the machine component, type of lubricant is used to minimise the mechanical changes in the machine. Lubricant being the product that separates two or more materials under movement. With modern machines being more and more sophisticated and tolerances being finer than before, cleanliness of Lubricants is critical, would the source of contamination be internal wear or external contamination. These contaminations rupture and compromises lubricant film, contamination particles when come in-between the fine tolerances, become cause of catastrophic failure,” expounds Gaurav Mathur.
At the same time, the industry is witnessing an opportunity to leverage digitalisation in lubrication management. Advanced lubrication tracking tools, coupled with ERP and maintenance software, can now offer real-time visibility into lubricant consumption, scheduling and health diagnostics. Integration of AI-powered analytics helps predict equipment failure based on lubricant data, enabling a shift from reactive to predictive maintenance. For Indian cement manufacturers aiming to digitise plant operations as part of Industry 4.0, lubrication is an ideal entry point that delivers immediate ROI and long-term gains in efficiency, asset life and sustainability.

Conclusion
As the Indian cement industry continues its trajectory of growth, the role of high-performance lubricants in ensuring operational reliability, energy efficiency and cost savings cannot be overstated. From kilns and crushers to ball mills and gearboxes, modern lubrication solutions are critical in
reducing downtime and maximising equipment lifespan. With rising demand and increased production pressures, cement plants must adopt a proactive approach to lubrication management—viewing it not as a routine maintenance task, but as a strategic pillar of plant performance.
Recent advancements in lubricant technology, such as synthetic formulations, nano-additives, and smart dispensers, have opened new avenues for boosting equipment efficiency and longevity. Digital tools and IoT-based systems now allow plant operators to monitor lubricant condition in real time, enabling predictive maintenance and minimising the risk of failure. As cement manufacturers increasingly pursue digital transformation and automation under Industry 4.0 frameworks, lubrication systems must be seamlessly integrated into broader asset management strategies.
At the same time, sustainability imperatives are reshaping lubrication choices. There is growing emphasis on biodegradable lubricants, optimised lubricant consumption, and environmentally responsible disposal practices. Overcoming challenges such as limited awareness, inconsistent maintenance practices, and cost sensitivity will require collaboration between lubricant manufacturers, OEMs and cement producers. The opportunities, however, are substantial—by aligning lubrication strategies with efficiency, digitalisation and sustainability goals, the Indian cement industry can significantly enhance its competitiveness and resilience in the years ahead.

CarbonStrong has raised Rs 125 million (125 mn) to scale a low carbon cement technology and build commercial production capacity. The startup was founded in 2022 by Harsh Jain and Vikramaditya Singh and has moved from customer trials to plans for industrial supply. The company said its material replaces up to 50 per cent of cement in concrete while reducing costs and improving durability.

CarbonStrong states the product is around 30 per cent cheaper than cement and compatible with existing concrete plants, reducing the need for new equipment and operational disruption. Trials and paid pilots have been conducted in Bengaluru, Hyderabad and Chennai with demonstration projects involving ready-mix firms and precast manufacturers. Compatibility with current workflows forms a central part of the commercial strategy, aiming to ease adoption by builders and contractors.

The funding will support construction of a facility with capacity of up to 100,000 tonnes (100,000 t) a year over the next two years to supply early customers commercially. The firm is also developing materials from steel slag, copper slag and mine tailings to expand its feedstock base, while noting the technical challenge of homogenising different waste streams. Recognition by HCL ClimaForce in 2026 and by the Avaana-Startup India-NITI Aayog AIM Grand Challenge in 2025 has underscored progress.

Industry adoption remains the principal test and will require consistent material performance, supply reliability and competitive economics. CarbonStrong projects the Indian market for cement substitutes could reach Rs 250 billion (250 bn) by 2030 and has set an ambition to produce 10 million tonnes a year by 2035 (10 mn t), a target far above its near term capacity. Moving from pilots to production demands capital, manufacturing discipline and customers willing to specify the material beyond demonstrations. The recent Rs 125 million raise is intended to fund the next phase of scale and to demonstrate that industrial waste can become a dependable input for lower carbon construction.

In a research-backed article, Dr SB Hegde examines why carbon-adjusted profitability and LC3 will decide the next set of winners in cement manufacturing.

The Indian cement industry has achieved world-class operational efficiency through lower specific energy consumption, high plant utilisation and a reduced average clinker factor of approximately 67.5 per cent. These traditional measures of operational excellence remain essential. However, they are no longer sufficient. Carbon now carries a measurable financial cost under India’s Carbon Credit Trading Scheme (CCTS) and under European carbon markets. Future leadership will be defined by carbon-adjusted profitability, the ability to generate strong returns while systematically lowering the carbon intensity of every ton sold.
Limestone calcined clay cement (LC3) offers a practical, scalable pathway to achieve this dual objective. By replacing up to 50 per cent of clinker with calcined clay and limestone, LC3 can reduce CO2 emissions by 30–40 per cent while delivering comparable or superior durability performance.
This article examines the technical foundations of LC3, European industrial practices, the emerging Indian carbon market and a concrete roadmap for Indian companies to embed carbon-adjusted metrics and LC3 into daily operations, incentives and commercial strategy.

Limits of traditional operational excellence
For many years, plant performance has been judged primarily by five indicators: specific heat consumption, specific power consumption, kiln and mill utilisation, clinker factor and overall equipment effectiveness. These metrics drove continuous improvement and helped the industry reduce energy use and increase the share of blended cement. Three structural changes have rendered them incomplete as sole measures of success.
First, carbon now carries a real or opportunity cost. Plants that improve volume or lower cash cost while raising or stagnating emissions intensity create a hidden liability that will surface as CCTS trading matures and as green procurement expands.
Second, lower-carbon products such as LC3 and high-performance blended cements are creating differentiated market segments. Customers in infrastructure, real estate and export-oriented construction are beginning to specify embodied-carbon limits.
Third, investors and lenders increasingly treat carbon intensity as a financial risk factor. Traditional KPIs can mask the divergence between short-term cash profit and long-term carbon-adjusted value.

What is carbon-adjusted profitability?
Carbon-adjusted profitability evaluates normal profit after explicit adjustment for carbon performance. A practical expression is:
Carbon-Adjusted EBITDA = Conventional EBITDA – Carbon Cost + Green Premium Income
Carbon cost may be an internal carbon price, the actual cost of purchasing Carbon Credit Certificates under CCTS, or the opportunity cost of high emissions relative to peers. Green premium income arises when customers pay more for verified lower-carbon cement or when the company sells surplus credits. Tracking both conventional and carbon-adjusted profit side-by-side gives management a clearer picture of value creation under evolving market rules.

Table 1. Traditional KPIs versus Carbon-Adjusted Leadership Metrics
Traditional Focus New Leadership Metric Why It Matters
Specific energy consumption Emissions intensity (kg CO2/t cement) Directly linked to future CCTS and CBAM costs
Kiln utilisation Carbon-adjusted contribution margin Reveals true value of incremental volume
Clinker factor Share of lower-carbon products sold (incl. LC3) Measures commercial success of the transition
Power cost per tonne Effective carbon cost per tonne sold Expose hidden liabilities
Absolute EBITDA Carbon-adjusted EBITDA + green premium Aligning profit with future market reality

LC3: Technical foundations and performance advantages
LC3 is a ternary blended cement that typically combines approximately 50 per cent clinker, 30 per cent calcined clay, 15 per cent limestone and 5 per cent gypsum (the classic LC3-50 formulation). The decisive technical advantage is that clay is calcined at 700–850 °C, far below the 1,450 °C required for clinker production. This lower temperature, together with the substantial reduction in clinker content, delivers CO2 reductions of 30–40 per cent relative to ordinary Portland cement (OPC).
Chemistry is synergistic. Calcined kaolinitic clay (metakaolin) reacts with calcium hydroxide from clinker hydration and with limestone to form additional C-A-S-H gel and carboaluminate phases. These phases densify the microstructure, reduce porosity and improve durability.
Field experience shows superior resistance to chloride ingress, sulphate attack and alkali–silica reaction. Early-age strength can match OPC with high-reactivity clays; later-age strengths routinely meet 42.5 and 52.5 grade requirements.
Importantly, LC3 does not require high-purity kaolin. Clays with 40 per cent or even lower kaolinite content can be activated successfully, expanding raw-material availability across India. Calcination can use adapted rotary kilns or dedicated flash calciners, making the technology compatible with existing plant infrastructure and far less capital-intensive than carbon capture.
Economic analyses show that LC3 can be produced at equal or lower cost than OPC in many locations because of reduced energy demand and cheaper clay. Life-cycle assessments consistently report 30–40 per cent lower embodied CO2 per tonne of cement.
Table 2. Comparative profile: OPC versus LC3-50
Parameter OPC LC3-50
Typical clinker content ~95 per cent ~50 per cent
CO2 emissions (relative) Baseline (≈0.85 t CO2/t cement process + fuel) 30–40 per cent lower
Clay calcination temperature Not applicable 700–850 °C
Key hydration products C-S-H, portlandite, ettringite C-A-S-H + carboaluminates
Chloride & sulphate resistance Good Superior
Production cost potential Baseline Equal or lower in most locations
Infrastructure compatibility Existing High (minor adaptations)

In India, commercial adoption has begun in earnest. JK Cement commenced the first commercial production of LC3 in the Indian subcontinent at its Mangrol plant in Rajasthan in 2025 under BIS standard IS 18189.
By early 2026, approximately 2,000 tonnes had been produced and sold, avoiding an estimated 500 tonnes of CO2. JK Lakshmi Cement followed with commercial launch of its Green PRO LC3 grade from the Jaykaypuram plant. As of mid-2026, two producers are supplying LC3 to the market. The first large-scale infrastructure application is the Noida International Airport (Jewar), where LC3 was used in the runway and a building complex, demonstrating full constructability and performance under demanding conditions. These early volumes are still small relative to national cement demand, but they mark the critical transition from pilot to commercial reality. Companies that scale capacity now will be positioned to capture both CCTS credits and emerging green-procurement demand.

Why the shift is accelerating
According to the World Bank’s State and Trends of Carbon Pricing 2026, direct carbon pricing now covers nearly 30 per cent of global greenhouse-gas emissions and generated more than US$107 billion in public revenue in 2025. The average global carbon price stands at approximately US$21 per tonne, although regional prices vary widely.
In Europe, the EU ETS price has traded near €80–85 per tonen in mid-2026. Free allocation for cement is being withdrawn in parallel with CBAM. European producers therefore face a clear signal: every tonne of avoided CO2 improves both compliance and competitiveness. Holcim has scaled calcined-clay production, including Europe’s first dedicated line at Saint-Pierre-la-Cour (France) and a second line in the Czech Republic (2026). Heidelberg Materials, Cementir (FUTURECEM) and others have commercialised low-clinker calcined-clay blends across multiple markets, showing that carbon-adjusted profitability is already reshaping capital allocation in the world’s most mature carbon market.India’s CCTS is now operational. Binding emission intensity targets apply to 186 cement facilities for FY 2025–26 and FY 2026–27. Average required reductions for integrated plants are modest (around 2.7 per cent by FY 2027), yet the direction is clear.
Trading of Carbon Credit Certificates is expected in the second half of 2026, with early prices likely in the `800–1,500 per tonne range. Plants that outperform targets can sell credits; those that underperform must buy them or face compensation. Cement is well positioned to be a net supplier of credits if clinker factor continues to fall through LC3 and other low-clinker systems.

Way forward for India
India starts from a strong baseline, world-class energy efficiency and a clinker factor already lower than the global average. The next competitive frontier is the deliberate reduction of process emissions through clinker substitution at scale. LC3 is uniquely suited to Indian conditions because suitable clays are widely distributed, the technology fits existing kiln and grinding infrastructure, and the resulting product can meet the performance demands of both infrastructure and building construction.
A practical national pathway contains five interlocking elements:

  1. Standards and acceptance: Accelerated finalisation and promotion of BIS specifications for calcined-clay and limestone–calcined-clay cements will remove a key barrier to commercial uptake. Alignment with European practice (EN 197-5) can facilitate knowledge transfer and export readiness.
  2. Supply-chain development: Investment in flash calcination capacity and systematic characterisation of regional clay deposits will secure reliable, low-cost feedstock. Existing rotary kilns can be adapted for initial volumes while dedicated calciners are built.
  3. Incentive alignment: Part of variable compensation for plant managers, sales teams and senior leadership should be linked to emissions intensity reduction and to the volume of lower-carbon products (including LC3) sold. Without this link, traditional volume and cost targets will continue to dominate behaviour.
  4. Product-level carbon accounting: Reliable measurement of emissions intensity at the individual cement grade level, supported by third-party verification where required, is essential for both CCTS compliance and credible green claims.
  5. Demand-side pull: Green public procurement policies that specify maximum embodied-carbon thresholds for major infrastructure projects will create a predictable market for LC3 and other low-carbon cements, accelerating scale and cost reduction.
    Companies that treat LC3 as a strategic product line rather than a niche offering will be better positioned to generate surplus Carbon Credit Certificates, capture any emerging green premium, and protect margins as carbon costs rise.

Organisational changes required
Technical capability alone is insufficient. Three organisational shifts are required.
Daily management: Emissions intensity must appear on the same daily and monthly dashboards as heat consumption, power consumption and utilization. Plant reviews should examine both conventional and carbon-adjusted results.
Incentives: A meaningful portion of bonuses for plant heads, technical teams and sales leadership should be tied to lower emissions intensity and successful commercialisation of LC3 and other low-carbon grades.
Commercial approach: Sales teams need clear volume and pricing targets for lower-carbon products, supported by technical service that helps customers specify and place the material correctly. Without commercial pull, excellent technical performance remains under-utilised.

Table 3. Three-stage roadmap to carbon-adjusted profitability
Time Horizon Priority Actions Expected Outcome
Next 12 months Add emissions intensity to plant dashboards; establish internal carbon price; initiate LC3 pilot production and customer trials Visibility and early organisational learning
12–24 months Revise incentive systems; scale LC3 and other low-carbon grades to key accounts; secure third-party verification capability People and sales aligned with carbon goals
24–36 months Embed carbon-adjusted metrics in board reporting and capital allocation; expand calcined-clay capacity Full system integration and competitive advantage

Questions senior leaders should ask
Boards can accelerate the transition by insisting on answers to a short list of questions:
• Is our carbon-adjusted profit improving, stable or declining relative to conventional EBITDA?
• Did recent volume growth improve or worsen our emissions intensity?
• What share of sales already comes from lower-carbon products, including LC3, and what is the trajectory?
• How exposed is our capital expenditure plan to rising carbon costs under CCTS and potential CBAM-related requirements?
• Do our incentive systems still reward only volume and cost, or have they been updated to include carbon performance?
Treating carbon with the same seriousness as energy cost or kiln utilization does not diminish operational excellence; it expands the definition of excellence to match the new competitive reality.

Looking ahead
By 2030 the gap between leading and lagging cement companies will not be decided by who records the lowest specific heat consumption. It will be decided by who delivers the strongest carbon-adjusted profits.
Absolute emissions may still rise as national production grows. That is not the issue. Companies that reduce intensity year after year and successfully sell cleaner products will pull ahead in both domestic and export markets. Those that do not will fall behind, even if their traditional efficiency numbers look strong.
Operational excellence built the Indian cement industry. It remains the foundation. It is no longer the complete picture. Carbon-adjusted profitability is the clearer measure of success.
LC3 is not a distant technology. It is available now. It cuts CO3 by 30–40 per cent, works with existing plants, and is already in commercial production in India. Companies that treat it as a strategic product, not a pilot, will protect their margins and generate tradable credits.
Leaders who act now will place carbon metrics on daily dashboards, link incentives to intensity reduction and LC3 sales, invest in calcined-clay capacity, and build commercial capability to sell lower-carbon products. They will shape the next chapter of the industry.

More Oversight Makes Cement Plants Less Safe

Published

Dijam Panigrahi makes a counterintuitive but data-backed argument that routing every sensor alert through human approval does not make cement plants safer.

India’s cement industry has spent the last two years wiring kilns, mills and coolers with sensors and automated control systems, and the safety case for doing so is strong on paper. Contract workers still make up the majority of the industry’s workforce, and fatal accidents remain a recurring problem. The Indian National Cement Workers Federation has noted that around 83 per cent of workers in the sector hold precarious positions, a fact that resurfaced after an oxygen cylinder explosion killed three contract workers at a plant in Chhattisgarh.
Industry tallies compiled by IndustriALL found cement plants recorded at least seventeen accidents in one year with 21 workers killed, and ten accidents the following year with nine killed, most of them contract staff. Automated monitoring, in theory, closes that gap. A sensor never gets complacent and never skips a check because a shift is short staffed.
However, plants that respond by routing every anomaly reading to a person for approval are quietly building a system that fails the same way understaffing does. When operators receive dozens of flagged deviations a shift, most of them minor, they learn a simple lesson: the fastest way through the queue is to approve without reading closely. The safety benefit disappears, not because the technology failed, but because the humans supervising it adapted to the volume.

Why alerts get ignored
A study cited by manufacturing technology publisher Applied SmartFactory found more than 95 per cent of alarms in a semiconductor fab were low priority, and only about 4 per cent ever triggered an action, with just 100 out of 5,000 alarms accounting for 70 per cent of all alarm activity. The mechanism is the same whether the trigger is a vibration sensor or an AI model flagging a kiln temperature swing. Once the ratio of noise to signal crosses a threshold, workers stop treating the system as a decision aid and start treating it as a formality to clear.
The scale of AI deployment underway makes this more than a theoretical risk. Stanford’s 2026 AI Index Report found organisational adoption of AI has reached 88 per cent, even as documented AI incidents rose to 362 in 2025, up sharply from 233 the year before, according to analysis of the report. The Index also found only about a third of organisations have adopted a formal governance framework, with NIST’s AI Risk Management Framework cited by 33 per cent and ISO/IEC 42001 cited by 36 per cent.
Most manufacturers are deploying monitoring systems faster than they are building the judgment for when a flagged event actually needs a person’s attention. In India, plants run by JK Cement have begun pairing CCTV feeds with AI to define safe zones around heavy machinery, a promising direction that still depends on operators trusting and reading the alerts the system generates.

A three-tier model for cement plant
The fix is not less monitoring or more monitoring. It is classifying decisions by risk and by novelty, rather than treating human oversight as a single switch that is either on or off. A workable model sorts factory floor events into three tiers.
The first tier, proceed, covers deviations the plant has seen before that fall within known safe bounds, such as a kiln feed rate adjustment within an established range. These should run without a stop for approval, because routing them to a person only trains that person to click through.
The second tier, pause, covers events that are unusual but not yet dangerous, such as a vibration reading trending toward a limit or a fuel blend shifting outside its typical mix. These warrant a brief human check before the system proceeds, giving an operator the chance to apply judgment the model does not yet have.
The third tier, escalate, covers events that are both high risk and unfamiliar, such as a pressure reading combined with a temperature spike that has no close precedent in the plant’s history. These should stop the process entirely and require a decision from someone with the authority to shut down a line.

Who should set the threshold
Where these tiers get drawn matters as much as the framework itself. Threshold setting is frequently handed to the vendor supplying the monitoring software or to a plant’s IT department, both of which understand the technology but not the specific tolerances of a given kiln, mill or line. Operations staff, who know that a particular grinding unit runs hotter under monsoon humidity or that a calciner behaves differently after a refractory reline, are better positioned to calibrate what counts as routine on their own equipment.
Handing threshold ownership to operations does not remove IT or vendors from the process, but it puts the calibration decision closest to the people who live with its consequences on the floor.

Signals that oversight is actually working
A few concrete indicators reveal whether a monitoring setup is functioning as intended or simply providing the appearance of safety. The escalation rate over time is the first: a rate that stays flat or climbs slowly as operations mature is healthy, while one that spikes and then falls sharply often means operators have started overriding the system rather than engaging with it. Time to resolution is the second: escalations that take progressively longer to close suggest fatigue or confusion about ownership, not diligence. The third, and most telling, is how accurate the system’s own uncertainty estimates turn out to be, meaning whether events flagged as high risk actually correlated with real incidents, and whether events waved through stayed incident free. A system whose escalations do not track with actual outcomes trains operators toward the same complacency that unmonitored equipment produces.
None of this argues against automation in Indian cement manufacturing, where a labor structure built on contract work and a track record of serious accidents make better monitoring an urgent need. It argues for treating human oversight as a design problem with three distinct settings, rather than a single
dial turned up whenever a plant wants to look safer on paper.
