Over the last 18 years, Nuvoco Vistas Corp has emerged as one of the major players in India through various greenfield and brownfield projects. The company’s plants in Chhattisgarh, Haryana, Jharkhand, Rajasthan and West Bengal account for an installed cement capacity of 10.92 mtpa. The company also has a pan-India presence in the ready-mix concrete business, with close to 70 plants across the country. Its aggregates business is based in north India with a capacity of 170 tonne per hour. What’s more, to undertake R&D activities to develop innovative solutions specific to unique requirements, the company established its Construction Development and Innovation Centre (CDIC) in Mumbai in early 2012. The centre endeavours to bring solutions closer to the market, accelerate the process and build up locally through systems development.

While Pranav Desai, VP – Research & Head CDIC, Nuvoco Vistas Corp, along with his team, recently took the ICR team on a detailed tour at CDIC, spread across 17,000 sq ft, to explain its working and activities, Madhumita Basu, Chief of Marketing, Innovation, Strategy and IT, Nuvoco Vistas Corp, shared insights about the company and its future plans in conversation with BS Srinivasalu Reddy of ICR.

CDIC clearly speaks of the company’s focus on R&D. Tell us about the company’s investment in this area.

We are not really chasing a particular percentage of the turnover. It is not about being among the top five research companies and investing a certain part of the business into this. Our focus is on building a robust agenda for the centre.

Concrete is a finished product, and being in the construction space, the genesis of CDIC has largely been the concrete space. So, the centre does not only look at just the material side of it, but the placement and finishing, and ensuring it is an end-to-end solution. Our spends are currently around 0.5 per cent and will be further driven as customers show keenness to work with innovative ideas and materials. The customer or his need is the initial point for our innovation. The centre has brought unique solutions like Duraguard Microfiber cement, light weight concrete, concrete of various strengths, including for metro projects, light emitting road pavers, etc. CDIC has also recently received NABL accreditation.

While the company supplies to projects pan-India, it has only one CDIC centre based in Mumbai. Does this pose a challenge?
The nuances are different in every place in India. Infrastructure projects are crucial today; yet 65 per cent of cement goes into Individual Home Builder (IHB) operations. Certainly, in our blueprint, in the next two years, we are looking at a satellite to this centre out of our concrete plants. Having received clearance for two, we are trying to push for another centre as well. So we are working around two centres between Delhi, Chennai and Kolkata this year. We need to operate closer to the customer and this will help in quick sampling, leading to a better interface with the manufacturing team. Also, at times, there has been a fair bit of delay between the concept of an idea and speed to market. The satellites would help address this issue.

Which building or infrastructure segment contributes maximum to your business?
A large bit of it is our cement footprint where again our focus is on the individual home builder. So that is a space which afforded an early opportunity to go with differentiated products. First with Concerto -a premium cement product. It is definitely the strongest cement, but the factors we work on in our cement design include the kind of workability and finish it can give. How will the mason working with the product be able to handle it because they have a tendency to make a batch and you do not always have a very scientific process there. The third feature of this product is finished whiteness. This is after understanding that consumers many times when they build their homes do not like to paint and finish together, they wait and see one monsoon if construction is okay, then I will conduct repairs and then I will go for painting and finishing. But if I give him cement which gives him a glow and good even finish along with good workability, so it helps. So this engagement with the consumer is the same principle today we are taking to World One or the hanging swimming pool as well. Like what was your need and then I have this basket, how can I fit it in.

What was your contribution to World One project?
The world’s tallest residential building, World One is 442 meters (m) tall, with a floor area of 1,50,000 square meters (sq m), 117 floors, and over 300 apartments. The construction of such a staggering structure was incredibly challenging, owing to potentially extreme wind resistance and wear and tear of its massive sub structure and slender super structures. Nuvoco conducted extensive research and testing of locally available raw materials and design mixed methodology, to create a unique high performance concrete (HPC) with a grade of C95-M125 and an MOE (Modulus of Elasticity) of 48-52 Gpa. Not only did it offer minimal shrinkage, creep, vertical pumping above 400 m, and high compressive strength above 100 MPa, but also provided the structure with increased tensile strength and better durability, including resistance to wear and tear, making the project a success.

Is bagged concrete a unique product where you have advantage or others have started bagging as well?
They have started now. But bagged concrete the entire design concept in fact it is probably a case example of the customer discovery process. The discovery deep dive was done in the Dharavi area and the conceptualisation was done to service markets where easy accessibility for not just a concrete mixer but to do site mixing without affecting the lives of neighbours. So, bagged concrete actually has figured as a solution there. But once you get into a solution you do not limit it. In Elephanta Caves, they wanted to do some construction. Obviously they zeroed in on our bagged concrete. So that is how acceptability and other utilities of the product emerge. But we started this entire process and we have the largest range in bags in terms of concrete, micro concrete and we are just launching mortar into the market.

Geographically, where does your strength lie in terms of sales?
Our concrete business is strong in the south and west. In the north and east, we are strong cement players. We service Madhya Pradesh and a part of Uttar Pradesh between our north and west plants. So we have a strong presence between the two businesses. There is definitely a leveraging base in the east and north for the concrete business. We are looking at some more home builder-specific solutions, for which we have started an engagement with our cement channel partners, particularly because we have the concrete range in bags. We have already kick-started this process in the east.

How many channel partners do you have?
Including the dealers and retailers we have in our northern, central and eastern footprint, there are about 18,000 to 19,000 channel partners. We continuously run engagements with them, such as loyalty-driven programmes and several other activities.

How do you see 2019 panning out for your company in terms of growth?
Cement and concrete mirror the same consistent growth rate, which has been consistent on a year-on-year basis at 6-7 per cent. At the micro-market level, there have been localised issues like that related to the sand mining ban in States such as Jharkhand, Bihar and Bengal; but some of these are correctional issues also that would be faced by any growing economy. In fact, I would see a little disruption in the first one or two quarters for two reasons one is the election process and then 45 days before cooling period will kick in. And by the time the budgets are out we will hit monsoons and the low construction activity. Markets in H2 will re-bound with encouraging growth figures expected at 9 to 11 per cent.

In Pyro, this is achieved by optimising fuel consumption (Coal / AFR), reducing Specific Heat Consumption and reduction in emissions (CO2, SOx and NOx) through continuous monitoring of thermodynamics in pyro and recommending set-points of crucial parameters in advance for maintaining stable operations.
Within the mill, this is achieved by improving throughput, reduce energy / power consumption and maintaining stable operations on a continuous basis. Our ROI-based value proposition captures the project KPIs like reduction of coal usage, increase of AFR, reduction of specific heat consumption (Kcal / Kg), reduction of specific power consumption (KWH / tonne), reduction of emissions, etc., by a specific percentage. This gives clarity to our customers to understand the investment vis-à-vis savings and estimate the recovery time of their investment, which typically is achieved within one year of DigiMine AI Pyro and Mill solutions implementation.

What role do digitalisation and motor monitoring play in overall plant energy optimisation?
Motors are being used extensively in cement production, and their monitoring play crucial role in ensuring continuous operation of applications. The monitoring system can automatically generate alerts for any anomaly / abnormalities in motor parameters, which allows plant team to take corrective actions and avoid any major equipment damage and breakdown. The alerts help maintenance team to plan maintenance schedule and related activity efficiently. Centralised and organised data gives overview to the engineers for day-to-day activities. Cement is amongst the top energy intensive industries in comparison to other industries. Hence, it becomes critically important to optimise efficiency, productivity and up-time of plant equipment. Motor monitoring and digitalisation plays a vital role in it. Monitoring and control of multiple applications and areas
within the plant or multiple plants becomes possible with digitalisation.
Digitalisation adds a layer on top of OT systems, bringing machine and process data onto a single interface. This solves the challenges such as system silo, different communications protocol, databases and most importantly, creates a common definition and measurement to plant KPIs. Relevant stakeholders, such as engineers, head of departments and plant heads, can see accurate information, analyse it and make better decisions with appropriate timing. In doing so, plant teams can take proactive actions before machine breakdown, enable better coordination during maintenance activities while improving operational efficiency and productivity.
Further using latest technologies like Artificial Intelligence can even assist operators in running their plant with minimal requirement of human intervention, which allows operators to utilise their time in focusing on more critical topics like analysing data to identify further improvements in operation.

Which of your high-efficiency IEC low-voltage motors deliver the best energy savings for cement mills or fans?
Innomotics India offers a range of IEC-compliant low-voltage motors engineered to deliver superior performance and energy savings, particularly for applications such as cement mills, large fans, and blowers. Innomotics has the complete range of IE4 motors from 0.37kW to 1000kW to meet the demands of cement industry. The IE5 range is also available for specific requirements.

These motors have ingress protection that prevents dust, moisture ingress and can withstand mechanical stress. These motors are available in IE3 / IE4 efficiency classes thereby ensuring lower energy consumption during continuous operation. These motors comply with relevant Indian as well as international standards.

How do your SD Severe Duty motors contribute to lower emissions and lower cost in heavy duty cement applications?
Severe duty motors enhances energy efficiency and durability in demanding cement applications, directly contributing to lower emissions and operational costs. With high-efficiency ratings (such as IE3 or better), they reduce power consumption, minimising CO2 output from energy use. Their robust design handles extreme heat, dust and vibration—common in cement environments—ensuring reliable performance and fewer energy losses.
These motors also lower the total cost of ownership by reducing downtime, maintenance and replacement frequency. Their extended service life and minimal performance degradation help cement plants meet sustainability targets, comply with emissions regulations and improve overall energy management—all while keeping production consistent and cost-effective.

What pump, fan or compressor drive upgrades have shown approximately 60 per cent energy savings in industrial settings and can be replicated in cement plants?
In the cement industry, the primary high-power applications are fans and mills. Among these, fans have the greatest potential for energy savings. Examples, the pre-heater fan, bag house fan, and cooler fans. When there are variations in airflow or the need to maintain a constant pressure in a process, using a variable speed drive (VSD) system is a more effective option for starting and controlling these fans. This adaptive approach can lead to significant energy savings. For instance, vanes and dampers can remain open while the variable frequency drive and motor system manage airflow regulation efficiently.

Energy efficiency has always been a cost-saving lever for the cement industry. Today, it is the backbone of sustainability and competitiveness. Cement manufacturers are under growing pressure to optimise consumption, diversify power sources and align with decarbonisation targets. Shree Cement has been at the forefront of this transformation, significantly scaling up its green power capacity and embedding advanced technologies across operations. In this exclusive conversation, MM Rathi, Joint President – Power Management, Shree Cement, shares insights on the company’s approach to energy efficiency, challenges in brownfield modernisation and long-term strategies for achieving net zero alignment.

What percentage of your total operational cost is attributed to energy consumption?
At Shree Cement, energy is one of the most significant components of production cost, accounting for nearly 30 per cent to 40 per cent of total operational expenses. Within this, thermal energy typically contributes around 20 per cent to 25 per cent, while electrical energy forms about 10 per cent to 15 per cent. The exact share varies depending on factors such as the fuel mix (coal, pet coke or alternative fuels and raw materials), the power source (grid-based or captive like solar, wind or thermal), raw mix quality, and regional fuel and electricity price variations. This makes energy efficiency and the adoption of sustainable power sources a key focus area, both from a cost and sustainability perspective.

How has your company improved energy efficiency over the past five years?
Over the past five years, Shree Cement has consistently invested in enhancing energy efficiency across operations. Our green power capacity, covering wind, solar and Waste Heat Recovery (WHR), has more than doubled from 245 MW in 2020 to 592 MW in 2025. All grinding units are now equipped with biomass firing facilities, reducing dependence on conventional fuels. From the project stage itself, we prioritise efficiency by selecting advanced technologies such as six-stage kilns with integrated WHR, CFD-designed plants, and equipment fitted with VFDs, centrifugal compressors and high-efficiency fans. We also review and upgrade equipment systematically, replacing fans, compressors, blowers, pumps, boilers and turbines with more efficient options. This continuous approach has reduced costs while significantly advancing our sustainability journey.
What technologies or practices have shown the highest energy-saving potential in cement production?
WHR stands out as one of the most effective solutions, offsetting a significant portion of electricity required for clinker production. Hot air recirculation has also proven highly beneficial in reducing heat losses. Additionally, regular energy audits help us identify opportunities for improvement and implement corrective measures in daily operations. Together, these practices play a critical role in optimising energy efficiency and driving sustainable operations.

What are the key challenges in adopting energy-efficient equipment in brownfield cement plants?
The biggest challenge is the significant upfront investment required for upgradation. Retrofitting existing facilities often involves complex civil and structural modifications, which add costs and extend downtime. Integration is another hurdle, as new high-efficiency equipment may not align seamlessly with older kiln systems, fans, mills or automation setups. These factors make the transition in brownfield plants more resource-intensive and time-consuming compared to greenfield projects.

How do you measure and benchmark energy performance across different plants?
We track key performance indicators such as specific heat consumption and specific power consumption for each unit, benchmarking them against internal and external standards. Thermal Substitution Rate (TSR percentage) is another critical metric, measuring the share of alternative fuels in the thermal energy mix. Internally, we benchmark performance across plants to encourage best practice sharing. Externally, we compare against national averages and align with the Bureau of Energy Efficiency’s PAT (Perform, Achieve, Trade) scheme, which sets Specific Energy Consumption (SEC) baselines and targets for cement plants. This multi-layered approach ensures continuous monitoring, improvement, and industry leadership in energy efficiency.

What role does digitalisation play in achieving energy efficiency in your operations?
Digitalisation is pivotal in driving energy efficiency at Shree Cement. IoT sensors integrated with SCADA and DCS systems allow real-time monitoring of parameters like heat consumption and energy use, moving beyond periodic reports. Our digital platforms consolidate plant data, enabling management to compare metrics such as SPC, SHC, kWh per tonne and kcal per kg across units in real time. This visibility supports data-driven decisions, faster corrective actions, and higher operational efficiency.

How do government policies and incentives influence your energy-saving decisions?
Government policies and incentives strongly shape our energy-saving decisions. The Perform, Achieve, Trade (PAT) scheme sets plant-specific SEC targets. Non-compliance incurs penalties, while compliance earns tradable energy-saving certificates. This ensures energy efficiency is both cost-driven and regulatory. Additionally, subsidies and viability gap funding for renewable energy projects in wind, solar and AFR co-processing help reduce payback periods and make energy-saving investments more viable.

What is your long-term strategy for aligning energy efficiency with decarbonisation goals?
Our long-term strategy aligns energy efficiency with India’s net zero 2070 goals. Key levers include improving efficiency, expanding green electricity, producing more blended cement, and increasing alternative fuel use. Today, more than 60 per cent of our electricity comes from green sources such as solar, wind, and WHR, the highest in India’s cement industry. Our blended cement products, which reduce limestone and fuel consumption, further lower emissions. These products are certified under the GreenPro ecolabel by CII, validating our sustainability practices and environmental standards.
