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!"

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:
- 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.
- 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.
- 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.
- 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.
- 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

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.
