Prashant Verma, Co-founder and India Head, Nanoprecise Sci Corp, discusses the exponentially growing importance of technology and IT initiatives in all the processes related to cement production.
Tell us about the role of automation and technology in achieving efficiency in cement plants. Technology has been playing a crucial role in transforming the operations of cement plants. It has paved the way for data-driven decision-making, which is now a hallmark of modern cement plants. The vast amount of data collected through automation systems is analysed to uncover operational inefficiencies and opportunities for process improvements. This data-driven approach enables plant personnel to optimise production schedules, increase productivity and stay ahead in a competitive market. Technological evolution has also enabled the implementation of predictive maintenance solutions, which help identify potential equipment failures before they occur. The emergence of predictive maintenance solutions has revolutionised maintenance practices in cement plants. With real-time data from IoT sensors and AI-powered algorithms, these systems can predict faults in equipment well in advance, thereby preventing any unplanned down or catastrophic failure. This proactive approach optimises maintenance schedules, minimises downtime, and ultimately reduces maintenance costs. Moreover, automation and technology help maintenance teams to identify the energy consumption patterns of equipment sets, allowing them to implement energy-saving measures, leading to cost reductions and environmental benefits.
As the production of cement is moving towards Industry 4.0, how are you incorporating digitalisation in cement plants? Embracing digitalisation is a key focus for a range of cement manufacturers across the country. Nanoprecise has been helping cement manufacturers incorporate state-of-the-art digital technologies to transform traditional cement plants into smart and connected facilities, for more than four years. One of our main efforts involves the deployment of Internet of Things (IoT) devices throughout the plant to monitor the health and performance of equipment in real time. These devices continuously collect data from the machinery, which is then transmitted to the cloud for analysis. The advanced signal processing algorithms parse through this complex machine health data to detect anomalies and predict potential equipment failures. This enables cement manufacturers to anticipate maintenance needs, helping plants optimise maintenance schedules, improve resource allocation, and avoid unplanned downtime.
How do you customise your solutions for each plant? Customers generally have needs and requirements that are unique, and a one-size-fits-all approach may not meet their specific requirements. We are working with businesses across a wide range of sectors around the world, to deploy customised solutions that help them drive their digital transformation journey. Customisation is an essential component of Industry 4.0 as each cement plant has unique operating conditions and equipment configurations. Our structured process involves conducting a comprehensive assessment of the plant, gathering real-time data using our ultra-low-power wireless sensors and analysing it using patented cloud-based software that detects even small changes in the machine performance and predicts the remaining useful life of any industrial asset. The solution can be customised to monitor a wide range of equipment including complicated machines like the roller press due to its ability to monitor low and ultra-low-speed applications with ease. It also allows for seamless integrations with various vertical and horizontal stacks. Moreover, the system can also be deployed on cloud or on-premise servers, thereby allowing for a simple plug and play, hassle-free deployment, without worrying about any extra IT infrastructure.
Tell us about AI-based machine productions? How does that help cement plants? AI-based machine productions involve utilising artificial intelligence algorithms to optimise the cement production process. Through machine learning, AI algorithms can analyse historical production data, sensor readings, and other relevant factors to make accurate predictions and recommendations. AI algorithms can monitor and analyse vast amounts of data pertaining to various production parameters to maintain consistent product quality. Moreover, by analysing data from various stages of production, AI can also identify inefficiencies and bottlenecks, suggesting optimisations to enhance overall process efficiency. Furthermore, AI can be applied to predict equipment failures and schedule maintenance activities, leading to minimal disruption and downtime. It can also optimise energy consumption by suggesting the most efficient operating conditions for equipment, thereby reducing energy costs and environmental impact.
What is the kind of data collected through automation systems? How does that help with cement operations? Automated AI-based predictive maintenance solutions consist of 6-in-1 wireless sensors that measure the 6 most important parameters of Tri-Axial Vibration, Acoustics, RPM, Temperature, Humidity and Magnetic Flux. These sensors act as the vigilant eyes and ears of the manufacturing plants, continuously monitoring the vital indicators of the health and performance of machinery. The combination of these six vital parameters equips cement plants with a holistic view of their industrial assets, allowing for data-driven decisions to optimise operations and prevent costly downtime. The collected data is then transmitted to the cloud through an encrypted and secured network for analysis. The AI analyses complex machine health data to discern subtle patterns, identify anomalies, and even predict potential equipment issues well in advance. This predictive capability is a game-changer for cement operations, as it empowers maintenance teams to take proactive measures before any critical failure occurs. By leveraging the power of automation and AI-driven analytics, the cement industry can reduce maintenance costs, enhance equipment reliability, and achieve higher energy efficiency, ultimately leading to improved productivity and profitability.
Can costs and production be optimised or enhanced with the digitalisation of cement plants? If yes, how? Digitalisation paves the way for implementing advanced digital solutions that can help maintenance teams transition from reactive to proactive maintenance strategies. Early detection of equipment issues enables planned maintenance, reducing costly unplanned downtime and minimising repair expenses. The state-of-the-art condition monitoring solutions available in the market, have the potential to revolutionise inventory management due to their predictive capabilities, thereby allowing for optimised resource allocation and reduced wastage of raw materials. This optimisation of inventory levels minimises carrying costs and mitigates the risk of overstocking or stockouts. Moreover, digitalisation allows for better monitoring of equipment’s energy consumption. By identifying the energy consumption patterns of equipment under faulty conditions, cement plants can take corrective actions to reduce energy wastage and carbon footprint, thereby achieving significant cost reductions over time.
What are the key skills required by plant personnel to transform them digitally? Our automated solutions are designed to serve a wide range of end users, irrespective of their technical proficiency or department within the cement plant. The system generates real-time alerts that prompt the user to take necessary action, ensuring seamless and efficient operations. Moreover, our state-of-the-art dashboard and visualisation layer enables end-users and technical experts to view data from multiple dimensions, delivering an intuitive and user-friendly interface. The seamless integration of these features fosters streamlined and optimised operations within the cement plant.
Tell us about the major challenges you face in the execution of technology in cement plants. Implementation of digital technologies such as predictive and prescriptive maintenance solutions is a challenging process in asset-intensive sectors like cement manufacturing. For instance, cement plants consist of various complex machines and equipment, each with its unique operating parameters and intricacies. Integrating and optimising technology solutions for such diverse machinery requires a deep understanding of the equipment and its operations. These plants operate in harsh and rugged environments, exposing the machines and equipment to extreme temperatures, dust, moisture and vibrations, which necessitates robust solutions that can withstand these conditions. Our solution comprises robust hardware that can monitor such machines, thereby bringing peace of mind to our customers. Our solutions undergo robust testing and validations to ensure their resilience in the rugged plant environment. Secondly, the introduction of new technology is generally followed by an adoption curve, which is why we provide extensive customer support. We focus on gaining staff acceptance and support as that is vital to the successful implementation of technology solutions. We achieve this by conducting effective training programs that address staff concerns and promote acceptance of the new technology. Moreover, implementing technology solutions in large cement plants can be a time-consuming process. However, with our plug and play solutions, we closely collaborate with teams in these plants to streamline the implementation, allowing for hardware installation in less than five minutes and facilitating seamless integration of digital technology. This expedites the adoption of our solutions, minimising downtime and ensuring a smooth transition. We ultimately strive to deliver technology solutions that excel in effectiveness and efficiency, ultimately optimising performance, enhancing reliability and fostering sustainable growth in cement plants.
Two cement concrete pavement roads covering a total stretch of 2.2 km in Akhoya village were inaugurated on 27th June 2026 by MLA Nuklutoshi Longkumer, who attended as the special guest. The project comprises the one km L Pangersowa Road and the one point two km Longchara Junction to RC Chiten Jamir Memorial Government High School road. A formal programme followed the inauguration at the school auditorium.
A technical report was presented by Er Waloniba of the Urban Engineering Wing-III, Kohima, which stated the project was sanctioned in March 2026 under the Special Assistance to States for Capital Investment scheme for 2025-26 at a sanctioned cost of Rs 29.1 million (mn). The work order was issued to M/s Ensign Construction on thirtieth April 2026 with a stipulated completion period of 12 months. Work commenced on fourth May 2026 and was completed on sixth June 2026, with the contractor and team finishing the tasks in around two months. The project included a single-lane cement concrete pavement with side drains, two slab culverts and breast walls at required locations.
Longkumer acknowledged the Chief Minister, the advisor for urban development, contractors and other stakeholders for the allocation and support, and he commended the contractor for early completion. He noted that cooperation from landowners and the community had been important in resolving land related issues that can otherwise delay developmental works. He emphasised that planned developmental activities carried out with collective effort would enable more projects to be implemented successfully.
The headmaster of RC Chiten Jamir Memorial Government High School, I Chubasenba Longkumer, outlined the school background, noting it was established in 1962, was earlier known as Government High School Changtongya and was renamed in 2014. Local representatives said the improved approach roads would ease access for students, staff, patients and the general public and fulfil a long standing aspiration of residents. A dedicatory prayer was offered by the pastor and the programme concluded with a ribbon cutting attended by village council and town council representatives.
Indian Cement Review (ICR) and Fuller Technologies brought industry, policy and technology leaders together to discuss how cement innovation can drive green construction at scale, writes Rakesh Rao.
India is building at a pace few countries can match. Highways, airports, housing, logistics parks, industrial corridors and urban infrastructure are reshaping the country’s economic geography. But beneath this growth story lies a difficult question: can India continue to build at scale without locking itself into a high-carbon future?
That question formed the core of an online panel discussion titled “Driving Green Construction Through Cement Innovation”, organised by Indian Cement Review (ICR) in association with Fuller Technologies as the Presenting Partner on June 25, 2026. The webinar brought together experts from cement technology, R&D, global industry platforms, building performance policy and international development cooperation to examine how low-carbon cement and material innovation can accelerate India’s green construction transition.
The discussion came at a crucial time. India has committed to achieving net-zero emissions by 2070 and reducing the carbon intensity of its economy by 45 per cent by 2030. At the same time, the country’s construction sector is expanding rapidly, driven by urbanisation, infrastructure development, housing demand and industrial growth. Cement, as one of the most widely used construction materials, sits at the heart of this transition. It is indispensable to development, but also central to the challenge of reducing embodied carbon in buildings and infrastructure.
Moderated by Nitika Krishan, Senior Urban Infrastructure and Sustainable Policy Consultant, the panel featured:
Dr Hemantkumar Aiyer, VP and Head R&D, Nuvoco Vistas Corp Ltd;
Devika Wattal, Innovation Lead, Global Cement and Concrete Association (GCCA);
Dr Sunita Purushottam, MD, GBPN India (Global Buildings Performance Network); and
Vaibhav Rathi, Senior Technical Advisor, GIZ (the German Agency for International Cooperation)
Setting the tone for the discussion, Nitika Krishan underlined the scale of the challenge before the sector. “The question before us is no longer whether we build, but how we build sustainably,” she said. She pointed out that construction accounts for nearly 40 per cent of global energy-related carbon emissions when both operational and embodied carbon are considered. Cement production, she added, remains one of the hardest industrial processes to decarbonise.
For India, this is not merely an environmental issue. It is a development issue, a competitiveness issue and increasingly, a market issue. As one of the world’s largest cement producers and among the fastest-growing construction markets, India’s material choices will influence the carbon trajectory of its built environment for decades. As Krishan observed, sustainability solutions in economies such as India must not remain limited to laboratory success. They must be scalable, commercially viable and practical at national level.
The innovation gap: From technology to market
Experts believe that there is a need to bridge the innovation gaps for making decarbonisation in cement and concrete scalable. Devika Wattal of GCCA, explained, “The starting point must be the core cement manufacturing process itself. The first and foremost is the heart of our process, the heart of cement manufacturing. How do we reduce clinker? That is always a topic where industry is working very intrinsically.”
Clinker reduction remains one of the most important pathways for lowering emissions in cement. Since clinker production is energy-intensive and chemically emits carbon dioxide, reducing the clinker factor through supplementary cementitious materials (SCMs), blended cements and new chemistries can have a significant impact. Wattal also noted that carbon capture, utilisation and storage (CCUS) will have a role, though it may not be the first lever for all markets.
However, she stressed that innovation cannot stop at technology development. A solution that works in the lab must also be adaptable to industry, scalable in production and acceptable in construction practice. “It is important for that innovation to be adaptable, to be scalable, and so that it can be executed in real time,” she said.
Wattal also called for stronger enabling systems around innovation. These include performance-based standards, product-level embodied carbon databases and clearer frameworks for evaluating green materials. Without these, low-carbon cement products may struggle to compete with conventional materials in procurement and design.
R&D must balance carbon, cost and performance
Bringing in the R&D perspective into the discussion, Dr Hemantkumar Aiyer of Nuvoco Vistas emphasised that low-carbon cement development cannot be treated as a single-variable exercise. Cement must perform in real construction conditions. It must deliver strength, durability, consistency and cost competitiveness, while also reducing carbon.
“The root of understanding and balancing all these aspects lies in materials, and knowing the materials,” he said.
According to Dr Aiyer, R&D teams must understand the variability of raw materials such as fly ash, slag and clinker. Different sources produce different material behaviours. This makes mix optimisation, material characterisation and processing-property relationships critical. When performance is affected, cement manufacturers must understand how strength enhancers, admixtures and other performance chemicals interact with the material system.
He also linked material science with process efficiency. Clinkerisation takes place at extremely high temperatures, around 1,400 to 1,450 degrees Celsius. Any improvement in raw mix design, process control or energy optimisation can, therefore, help reduce emissions and cost. Dr Aiyer pointed to artificial intelligence-based optimisation, Cement 4.0 tools and advanced software as important enablers for real-time process and material control.
“The more you understand the materials, the more you can control it,” he said.
LC3: The promise is proven, the sequencing is not
Limestone calcined clay cement, commonly referred to as LC3, has attracted global attention because it can reduce clinker content significantly by using calcined clay and limestone while maintaining performance in many applications. Kiranmai Sanagavarapu of Fuller Technologies said the technology itself has already moved beyond proof of concept. Fuller Technologies has worked with calcined clay technology for nearly two decades and has seen plants running in France and Ghana. These plants, she said, are meeting local and national specifications, while the economics are beginning to make sense.
“The calciner is performing, the economics is stacking up, it is making business sense to produce,” she said.
But if the technology is viable, why has adoption not scaled faster? For Sanagavarapu, the answer lies in project sequencing. Too often, clay characterisation happens after equipment is specified. This, she warned, is a backward approach because calciner design depends on clay mineralogy, kaolinite content, iron levels, reactivity, moisture and other variables.
“If you don’t know what your deposit looks like before you commit for the equipment, you are, in a way, going blind into designing,” she said.
She also identified permitting and plant integration as major bottlenecks. Environmental clearances, mining permissions and local regulatory approvals must begin early. Similarly, calcined clay must be integrated into existing grinding, blending and logistics systems from the design stage, not treated as an afterthought during commissioning.
India already has IS 18189:2023 standard for LC3, but Sanagavarapu pointed out that the standard is not yet visible enough in procurement documents. “The gap between what is technically being permitted and what the procurement is asking is the single biggest bottleneck,” she said.
In her view, successful scale-up depends on getting the sequence right: clay characterisation first, permitting in parallel, standards aligned with construction, and integration built into plant design.
India’s LC3 journey: Progress, but demand remains thin
Providing details of India’s LC3 commercialisation experience, Vaibhav Rathi of GIZ noted that JK Cement carried out the first commercial production of LC3 at its Rajasthan plant, followed by JK Lakshmi Cement three months later. These initiatives were supported by the International Climate Initiative of the Government of Germany, with IIT Delhi contributing deep institutional knowledge on LC3 research and BIS certification.
Rathi said India’s early experience has produced clear lessons. One of the biggest was the need to build capacity among regulators. While BIS certification existed, State Pollution Control Boards were unfamiliar with the technology and unsure about the approval pathway.
“The capacity building is not just needed amongst the producer and the users of the cement, but also the regulators who are working with this technology for the first time,” he said.
He also highlighted the need for better information on China clay deposits. Since China clay is currently classified as a minor mineral, centralised data on availability, quality and location is limited. If cement manufacturers are to adopt LC3 at scale, stronger mineral intelligence will be important.
The third issue is demand. LC3 has already been used in projects such as Palava City in Mumbai and Noida International Airport, but these remain limited examples. “It is in a chicken and egg situation,” Rathi said. “Cement companies are saying we need more demand, and users are saying there is not enough cement available.”
Public procurement, he suggested, could help break this cycle. If agencies such as CPWD and other public bodies begin testing, accepting and specifying LC3, it could create the market confidence needed for cement companies to invest in production and storage.
Building codes must catch up with innovation
Dr Sunita Purushottam of GBPN India argued that material choices will determine built environment emissions over the long term, but India’s current policy signals remain fragmented. Although LC3 has received BIS recognition, she pointed out that building codes, municipal bylaws, schedules of rates and sustainability codes do not yet provide uniform guidance on low-carbon cement.
“The current cement regulations are largely prescriptive and favouring traditional materials,” she said. This limits the ability of alternative materials to compete on performance, durability and emissions.
Dr Purushottam also raised the issue of taxation. Cement, including LC3, currently falls under the same GST bracket as conventional cement. A differentiated tax structure, she argued, could help accelerate market adoption. “In order for the market to demand LC3, that differentiation in the GST could go a long way,” she said.
She noted that green building certifications such as IGBC and GRIHA are already creating demand for low-carbon materials by assigning points for embodied carbon and sustainable material use. However, she said large-scale adoption will require regulatory mandates, particularly through building codes and state-level notifications.
She also cautioned that low-carbon cement alone does not solve the entire building performance problem. A material may reduce embodied carbon, but the operational carbon of a building depends on thermal performance, design, insulation and energy use. “The energy part has two elements,” she said. “One is the embodied carbon of the material itself, and the other is the operational carbon.”
Collaboration is the bridge between invention and impact
Wattal said GCCA sees innovation as a strategic priority and works through platforms that connect industry with academia and start-ups. “There is no way we will decarbonise our sector without innovation,” she said.
However, she stressed that research must be connected to actual industry challenges. Innovations developed in isolation may fail when they encounter real-world barriers such as raw material variability, plant integration, cost, standards and finance. Start-ups, too, need industry mentorship and scale-up pathways.
Wattal also flagged the importance of finance. Even strong technologies may struggle to attract investment if there is no common understanding of bankability. “We have always put projects into, is this a bankable project? But the definition of a bankable project has never been defined,” she said.
For India, she saw strong potential in its academic and start-up ecosystem, but said the challenge lies in alignment and prioritisation. The country has the research base, industrial capacity and market size. What it now needs is a coordinated route from innovation to deployment.
There is a practical concern for cement manufacturers: how can existing plants be adapted for lower emissions without compromising reliability or commercial viability?
Kiranmai Sanagavarapu addressed, “The reliability risk in calcined clay retrofit is definitely real, but it is almost always self-inflicted. The risk arises when a new process is added to an existing circuit without properly redesigning grinding and blending configurations.”
Existing cement plants, she explained, can take two broad routes. The first is external sourcing of calcined clay combined with mill optimisation. This requires lower capital investment and can potentially move in 12 to 18 months if other conditions are in place. It may reduce emissions by around 20 to 30 per cent. The second route is integrated calcination on site, which requires higher capital expenditure and longer lead times, but provides greater control over quality, supply and emissions reduction potential.
For Sanagavarapu, the principle is simple: low-carbon retrofits must be designed with intent. “Design it with an intent properly from the start. Start in the market conditions where the economics are already working,” she said.
Circularity: The overlooked advantage
According to Vaibhav Rathi, fly ash and slag are already well established in cement and construction (C&D), but construction and demolition waste remains underutilised. “C&D waste is a growing business opportunity which not many have taken up,” he said. India’s continuous construction and demolition activity creates huge volumes of waste, much of which contributes to air pollution, land degradation and material inefficiency. With the right processing and standards, this waste can be converted into useful construction products.
Rathi also pointed out that LC3 has a circular economy dimension that is often overlooked. It can use low-grade kaolin-rich clay left behind after high-grade clay is extracted for other applications. “LC3 is not only a low-carbon solution, but also a circular economy solution,” he said.
At the same time, he cautioned that LC3 in India is not yet cheap because it has not reached scale. Site-specific techno-commercial feasibility studies, supported jointly by development agencies and industry, could help companies assess whether LC3 production makes technical and financial sense at a given location.
Dr Purushottam added that India must address both low-carbon cement and construction waste together. “Both low-carbon cement and C&D waste go hand in hand. India does not have an option but to work on both,” she said.
Dr Aiyer called for policy shifts from both government and industry, including preferential purchasing of sustainable materials, minimum supplementary cementitious material requirements in public and public-private projects, and faster regulatory implementation. “If we can fast-track the regulatory standards and their implementation on the ground, that is the way to go,” he said.
From green ambition to green construction
Cement innovation is no longer only about chemistry. It is about systems. Low-carbon cement will scale only when technology, standards, procurement, finance, regulation, education and construction practice move together.
LC3 and other low-carbon technologies have shown promise. India has early commercial examples, strong research capability and growing market interest. But mainstream adoption will depend on whether demand can be created, regulators can be capacitated, standards can be embedded in procurement, and manufacturers can see a clear business case.
For a country building at India’s scale, the opportunity is enormous. Cement will continue to be central to infrastructure and urban development. The challenge now is to ensure that the cement used in India’s growth story carries a lower carbon burden.
