Sanjay Kumar Khandelwal, Head – Power Plants, JK Cement, shares details about the working of waste heat recovery systems (WHRS) and its benefits, while elaborating on the efforts undertaken by his company to become energy-efficient.
What are the alternative or renewable sources of energy used by your organisation for the process of cement manufacturing?
At JK Cement, we are at the forefront of our sustainability journey. To achieve our clean energy targets, the alternative renewable energy sources used by our organisation are solar plants, wind energy, hydel energy, biomass and waste heat recovery systems (WHRS). The use of alternative fuels and raw material (AFR) to substitute fossil fuels has also been initiated.
We have installed WHRS with all the kilns except one kiln which we are planning to install in FY 22-23. In FY21 our Green Power Mix was 25 per cent and we are working to increase it to 75 per cent by FY 2030.
We started our AFR journey in FY 2013-14 with a very small quantity and now we have achieved a TSR of 6.5 per cent in FY 2020-21. We are proud to share that we have achieved a TSR of 20 per cent at one of our plants. To achieve the TSR target of 35 per cent we have made huge investments for installation of shredder, covered storage shed and feeding arrangement for both solid and liquid waste, refuse derived fuel (RDF), plastic waste etc. Further, to overcome the operational challenges we are installing chlorine bypass, an outside burning system and more shredders are also in the pipeline. For the supply side, we have recently signed a MoU with PRESPL for the supply of biofuel and biomass to achieve the proposed TSR target of 35 per cent
When did your organisation install the WHRS in cement plants and what were the key considerations taken into account while doing the same?
The first WHRS with a capacity of 13.2 MW was commissioned in 2008 at JK Cement Works, Nimbahera. Recently in our plant at Mangrol, we upgraded the capacity to 29.1 MW from 10 MW after the installation of Kiln-3. Our objective was to generate power without any additional fuels, maximise utilisation of waste heat generated from kiln operations, minimise heat losses into the environment and finally minimise water consumption.
What was the energy consumption of the plant prior to the system and how has that changed post installation?
Installation of WHRS plays a major role in not only reducing the overall energy consumption cost but also the requirement of other available non-renewable energy resources. This has resulted in minimising the Grid and CPP as a result of implementing WHRS to meet our energy requirements. Apart from that, regular monitoring of WHRS parameters and process optimisation is being done on a regular basis to recuperate maximum heat from the system so as to generate maximum power and to keep the WHRS system efficient.
How does the process of waste heat recovery work? What is the technology used by your organisation for its functionality and monitoring?
WHRS works on the thermal Rankine Cycle concept. Steam (hot gases) emitted from the preheater exit as well as clinker cooler from the Kiln operations, enters into the WHRS system. The steam then passes through the turbine to further the power generation process.
In order to ensure that our power generation is as efficient as possible, we have adopted the best operating and maintenance practices. This includes operating from a central control room using a state-of-the-art PLC-based operating system while keeping manual intervention to a minimum. We also compare the actual results with the design and the best data on a daily basis, making any adjustments necessary in real-time besides conducting regular system audits to ensure the efficiency of our WHRS.
On an average, energy cost is around 40 per cent of the production cost for cement manufacturing. What is the impact of the waste heat recovery system on the energy cost of the cement plant?
WHRS utilises hot gases emitted both from preheater as well as clinker cooler to generate power without the usage of any additional fuel. In other words, we are able to generate power without utilising any fossil fuels; which not only reduces overall carbon footprints but also restricts hot gases from entering into the atmosphere. This system results in reducing the overall cost of production by reducing overall power consumption cost followed by a reduction in cost through optimum power mix (maximum usage of WHRS and renewable power sources and least usage of grid and CPP power) through effective power management.
The WHRS is a major contributor towards reducing the carbon footprint. Tell us about its impact and support in achieving the decarbonising goals of the cement industry.

What other technological or automation advancements can contribute towards making the process of cement manufacturing energy optimised?
To name a few: VFD installation, PID-based automation, low DP control valve installation, high energy efficient fans, high efficient motors, PF improvement system, cross country belt conveyors for material conveying, installation of horizontal roller press (HRP) mills with lower specific energy consumption, high efficiency cooler, lower pressure drop preheater, high efficiency latest motors, mechanical conveying in place of pneumatic conveying, replacement of reciprocating compressors with screw compressors, automation of compressed air pressure as per requirement with installation of controller, adopting drip irrigations to conserve water, regular audits etc, can all go a long way in improving and optimising cement manufacturing process.
Are there any specific researches taken in the direction of finding more alternative sources of energy that have a lower impact on the environment?
At a global level, to extract heat at a low temperature range, Organic Rankine Cycle based power generation, Vapour Absorption Machine, water heating and the use of CPP are some of the latest developments, which contribute a lot in reducing the carbon footprint. However, this requires very high capital investments.
The use of green hydrogen as an alternative fuel, electrification of clinkering process, use of concentrated solar energy for producing clinker are the fields that can be explored that has the potential to lower environmental impact
How do you foresee the future of energy consumption in the cement manufacturing process and its impact on the end product cost?
World energy demand is expected to increase by 35 per cent by 2030 as developing nations have to modernise and expand their economic output. This creates a near impossible scenario for secure, low carbon energy supplies to keep pace with this demand. So, the need of the hour is to be 3 times more energy efficient!
In today’s scenario, the cement industry is becoming more and more energy efficient not only through its process optimisation but also by adopting newer technologies. Waste Heat Utilisation is now a proven technology and has become an integral part of the cement manufacturing process. AFR is another viable option that has the potential to reduce the consumption of fossil fuels. This can not only help in reducing carbon footprint but also improve cost economics besides reducing environmental impact. Other industry wastes like slag, red-mud, zinc waste etc. and hazardous wastes along with biomass are also being used.
Chemical gypsum and similar alternative raw materials are also being used in the cement process. This has not only made the manufacturing process energy efficient but has also optimised the end product cost. However, other factors like increasing fuel and raw materials cost, manpower, overheads, logistics and mining cost etc. are major concerns that can increase the end-product cost, therefore, nullifying the effect of optimisation and energy efficiency.
With a strong focus on AFR usage, the challenge that we face is in terms of its availability, utilisation, economic and technical feasibility. This also requires creating an ecosystem that supports its adoption. Therefore, regulatory authorities need to come forward and help take this to the level that has been achieved by developed countries.

ABB reconditions 25 drives at ACC’s Jamul cement plant, avoiding 16 tonnes of CO₂ emissions while improving reliability through predictive maintenance.
Chhattisgarh
ABB has signed a multi-year Motion OneCare service agreement with ACC Limited, part of the Adani Group, to modernise ageing industrial drives at its Jamul cement plant in Chhattisgarh, improving operational reliability while avoiding approximately 16 tonnes of carbon dioxide (CO₂) emissions without disrupting production.
Announced on 27 October 2026, the agreement combines scheduled drive reconditioning, digital condition monitoring and energy appraisals to extend equipment lifespan, improve plant uptime and optimise maintenance costs. The initiative marks a shift from conventional equipment replacement towards a more resource-efficient approach to industrial asset management.
The first phase, completed in April 2026, involved the on-site reconditioning of 25 ABB ACS800 variable speed drives without a major plant shutdown. By retaining the existing cabinets and restoring the drive modules rather than replacing entire panels, ABB helped ACC preserve capital investment, minimise material consumption and avoid approximately 16 tonnes of CO₂ emissions.
A second phase, covering an additional 25 ACS800 drive modules, is scheduled for the fourth quarter of 2026. The programme is designed to improve long-term equipment reliability while allowing maintenance activities to be aligned with the plant’s operational schedules.
The ACS800 drives, installed at Jamul in 2010, had delivered more than a decade of near-continuous service in demanding cement manufacturing conditions. However, ageing electrical components and changing fault patterns had begun to affect their ability to meet the plant’s reliability requirements.
Rather than opting for complete equipment replacement, ACC engaged ABB’s certified engineers to conduct a comprehensive asset health assessment. The evaluation found that the existing cabinets and enclosures remained structurally sound, making targeted reconditioning a technically viable and cost-effective alternative to full replacement.
Drawing on nearly two decades of experience with ACC’s equipment and operating requirements, ABB developed a maintenance framework tailored to the plant’s shutdown windows, budget cycles and production priorities.
The Motion OneCare agreement incorporates planned equipment restoration, condition-based monitoring and energy assessments, enabling ACC to adopt a more systematic approach to maintaining critical electrical infrastructure.
As part of the programme, ACC has implemented ABB Ability™ Digital Powertrain Insights to monitor drive performance and identify emerging operational issues before they result in equipment failures.
The digital platform provides continuous visibility into parameters such as temperature, current, vibration and fault patterns. These insights allow maintenance teams to detect early signs of equipment deterioration, schedule interventions more effectively and reduce the likelihood of unexpected downtime.
Amit Gupta, Local Division Manager, Motion Services, ABB India, said: “We know what unchecked wear costs over time: a small inefficiency that eats away at ROI for years. At Jamul, the evidence pointed clearly to assets with productive life still in them.”
“Our job was to restore them properly and give the team the tools to stay ahead of the next problem. At ABB, we don’t just fix what fails. We want to protect what works.”
The initiative also demonstrates the growing relevance of circular economy principles in cement manufacturing, where extending the service life of existing industrial equipment can reduce capital expenditure, material consumption and the environmental impact associated with manufacturing replacement components.
According to ABB, drive reconditioning can reduce lifecycle emissions by 50 to 80 per cent compared with complete equipment replacement. By preserving functional components and restoring critical modules, the process helps retain the economic and material value of existing industrial assets.
The addition of energy appraisals in subsequent phases will further expand the programme beyond equipment restoration, enabling ACC to assess drive performance, identify energy-saving opportunities and improve operating efficiency.
For cement manufacturers, variable speed drives play an important role in controlling motors and optimising energy consumption across production processes. Maintaining their reliability and efficiency is essential for minimising operational disruptions and managing electricity costs.
Vinod Bahety, CEO – Cement Business, Adani Group, said: “Moving from reactive firefighting to a structured maintenance plan was exactly what this operation needed. That kind of peace of mind doesn’t come easily. It comes from a partner that understands how your business runs.”
“We didn’t need a full system overhaul; we needed expert support, actionable insights, and a plan we could execute around our schedule. That’s what we got.”
The project supports ACC’s broader strategy to improve manufacturing efficiency through digital transformation, preventive maintenance and sustainable asset management.
ACC, a subsidiary of Ambuja Cements and part of the Adani Group, operates 20 cement manufacturing facilities and 119 ready-mix concrete plants across India. The company has been advancing initiatives focused on renewable energy, circular economy practices and technology-driven operational improvements.
Alongside Ambuja Cements, ACC is part of a large-scale building materials business committed to achieving net-zero emissions by 2050, with near-term and net-zero targets validated by the Science Based Targets initiative (SBTi).
The Jamul initiative aligns with these sustainability objectives by demonstrating how equipment life extension and digital monitoring can contribute to resource efficiency without requiring large-scale replacement of existing infrastructure.
ABB, a global technology company specialising in electrification and automation, brings more than 140 years of industrial expertise and employs approximately 110,000 people worldwide. Its Motion Services business supports industrial customers through equipment maintenance, modernisation, digital monitoring and lifecycle management solutions.
The agreement also reflects a wider shift in industrial maintenance practices, with manufacturers increasingly adopting predictive technologies to improve equipment availability, manage costs and reduce unplanned shutdowns.
With 25 drives already reconditioned and another 25 scheduled for restoration, ABB’s collaboration with ACC illustrates how targeted modernisation, digital monitoring and circular maintenance practices can extend the operational life of critical equipment while supporting more efficient and sustainable cement production.
