Early adopters can realise competitive advantages by leveraging digital technologies to identify and propagate best practice throughout their organisation, creating value for stakeholders.
ROLE OF AUTOMATION IN CEMENT INDUSTRY Automation has a significant role to play in the cement industry. Here are some examples of how automation is being used in the industry:
Artificial intelligence shall be used to analyse production data, to optimise processes and reduce energy consumption
Process control: Automation systems can be used to monitor and control various stages of the cement production process. This includes controlling the raw material feed, grinding, and blending of raw materials, and the kiln and clinker production process. By automating these processes, cement companies can improve product quality, reduce energy consumption, and increase production efficiency. Quality control: Automation systems can be used to monitor the quality of cement at various stages of production. This includes monitoring the chemical composition of raw materials, the fineness of grinding, and the composition of the final product. By automating quality control, cement companies can ensure consistent quality and reduce waste. Maintenance: Automation systems can be used to monitor the condition of equipment in real-time, enabling predictive maintenance. By using data to predict when maintenance is needed, cement companies can reduce downtime and optimise maintenance schedules. Logistics: Automation systems can be used to optimise logistics processes, including transportation, storage, and distribution. By automating logistics processes, cement companies can reduce transportation costs, improve inventory management, and increase delivery efficiency. “For the cement industry we primarily have bulk loading systems with an objective to reduce fugitive emissions that are generated while bulk loading. This means that we are trying to control dust at the cement plant,” says Venkatesh Ravula, CEO, DCL Bulk Technologies. “We are the first organisation to bring this technology to the customers which makes us leaders in the field of dust emission control while bulk loading. Over a period of 4 decades, we have constantly upgraded our products and have made them better suited to the Indian requirements,” he adds. Safety: Automation systems can be used to improve safety in the cement industry. For example, automated systems can be used to monitor the emission of pollutants, detect potential hazards, and improve emergency response times. By improving safety, cement companies can protect workers and reduce the risk of accidents. Automation has a significant role to play in the cement industry. By automating processes and leveraging data, cement companies can improve product quality, reduce energy consumption, optimise maintenance schedules, improve logistics, and enhance safety.
EFFICIENCY FROM SOFTWARES AND MONITORING SYSTEMS To achieve efficient and productive functionality in plants, multiple softwares, equipment, and monitoring systems are installed to ensure that production processes run smoothly, and equipment operates optimally.
By automating logistics processes, cement companies can reduce transportation costs, improve inventory management, and increase delivery efficiency.
Monitoring systems help ensure consistent product quality by providing real-time data on the production process. By monitoring production parameters, such as temperature and pressure, operators can quickly detect and correct any deviations that could impact product quality. They also help in identifying inefficiencies in the production process, such as equipment breakdowns, and can trigger automated responses to reduce downtime. This reduces the time and cost associated with maintenance and repair. “We are an AI and IoT based predictive and prescriptive maintenance solution company. We predict the maintenance of equipment and save downtime for the plant which can cause millions of dollars to the organisation. We have an IoT device which can calculate six parameters like vibration, temperature, humidity, acoustic data, electric signals and the speed of the machine. Once this data is retrieved from the machine, the cloud systems analyses this data and comes up with analytics with its algorithm,” says Prashant Verma, Co-Founder and India Head, Nanoprecise Data Services. Monitoring systems can help reduce operational costs by optimising energy consumption and reducing waste. By monitoring energy usage and production data, operators can identify opportunities for improvement, such as reducing the use of raw materials or optimising kiln temperatures. They also help improve maintenance operations by providing real-time data on equipment performance. This enables predictive maintenance, where maintenance tasks are scheduled before equipment failures occur. This reduces downtime, reduces the cost of repairs, and increases equipment lifespan. “Our instruments are mainly used for the purpose of efficiency measurements. We have equipment that helps measure ultrasonic heat in the preheaters which helps detect any irregularity in the temperatures. This helps them take corrective action, thus, preventing damage or slowing down of the plant which leads to better efficiency. Similarly, we have multiple equipment that support the efficiency of cement plants,” says Piyush Patel, Head – Strategic Business, Testo India. Monitoring systems help improve safety in the Indian cement industry by monitoring equipment for potential hazards and detecting potential safety risks. Automated responses can be triggered to prevent accidents, and operators can be alerted in real-time to potential issues. monitoring systems have numerous advantages for the Indian cement industry, including improved product quality, increased efficiency, cost reduction, enhanced safety, and improved maintenance. By investing in monitoring systems, Indian cement companies can become more competitive, sustainable, and efficient.

SUSTAINABILITY WITH TECHNOLOGY Technology can play a critical role in achieving sustainability in cement production by improving energy efficiency, reducing carbon emissions, reducing waste, and improving production processes through digitalization and data analytics. To achieve Net Zero, it is essential to use alternative fuels and raw materials. Growing technology in the Indian cement industry can help in analysing and adjusting equipment of fuels and raw materials that can make a viable end product that serves the purpose and protects the planet. Keyur Shah, Business Manager, SB Engineers, says, “As far as alternative fuels are concerned, petcoke, lignite, municipal wastes etc., are being used. When fuel type is changed, the burning process changes. The calculation with a different fuel is the quantity of fuel that needs to be pumped in to achieve the thermal balance in the burning zone area. It becomes more relevant to monitor and understand thermal knowledge in this scenario. Cement industry is using cementitious materials in their raw mix. Flyash or gypsum is mixed with clinker and then grinding is done. The percentage of this mix varies and grinding properties also change accordingly. What needs to be monitored is the particle size to understand if the process of grinding is giving an optimum output. Our equipment help monitor the changes in process when alternative fuels are used and when the raw mix has other cementitious materials in various proportions.” Technology can help improve the energy efficiency of cement production equipment, such as kilns and mills. Advanced process control systems can optimise production parameters, such as temperature and pressure, to reduce energy consumption. Additionally, energy-efficient motors, variable speed drives, and heat recovery systems can help reduce energy usage. “In the area of AFR, we are working on equipment and are one of the first ones to provide solutions for AFR when the equipment was newly installed and even spares were unavailable in the country. Many esteemed groups in the country use our solutions for AFR and life enhancement of these components. When it comes to heat, Vautid has always been working on areas where heat is an integral part of the process and leads to wear. Our products are designed in a manner to meet a combination of wear requirements, mostly to do with heat” says Anand Sundaram, Managing Director, Vautid India. Newer technologies like carbon capture are slowly advancing in the Indian cement industry and can revolutionalise the decarbonisation mission of the industry. Similarly, data analytics can help optimise production processes by identifying areas of improvement, reduce energy consumption, and improve product quality. Digitalisation can also help improve supply chain efficiency, reduce logistics costs, and improve inventory management. Technology can also help cement companies recycle waste materials from the production process, such as slag or fly ash. This reduces waste and conserves natural resources. Additionally, technology can help companies optimise the use of water and reduce the amount of wastewater produced during the production process. With the use of softwares, monitoring systems, better machinery, newer technologies and taking the digital route, the Indian cement industry is moving towards cost and energy effective cement manufacturing, which is going to benefit the industry with better production value in the long run.
India’s cement sector has improved its energy and carbon efficiency, but rising groundwater use in water-stressed regions and deteriorating worker safety remain significant concerns, according to a report by the International Forum for Environment, Sustainability & Technology (iFOREST). The findings also highlighted weak policy implementation and gaps in sustainability reporting.
India, the world’s second-largest cement producer, uses about 2.54 gigajoules of energy per tonne (GJ/t), below the global average of 2.88 GJ/t. However, renewable sources accounted for only 5.1 per cent of the sector’s energy mix, indicating continued dependence on conventional sources.
The report assessed 18 cement companies against 107 Business Responsibility and Sustainability Reporting indicators for FY24 and FY25. The companies covered 87 per cent of India’s cement production. Carbon emissions intensity declined from 0.58 to 0.57 tonnes of carbon dioxide per tonne, but total emissions increased 4 per cent to 224.3 mn t, equivalent to about 6 to 7 per cent of India’s overall emissions.
Overall water withdrawal declined 9.5 per cent during the study period, while withdrawals in water-stressed areas, mainly in Rajasthan, increased by more than 20 per cent. Groundwater’s share of withdrawals in these areas rose from 27 per cent to 38 per cent, raising concerns about the sector’s impact on vulnerable water resources.
The sector employs about 228,000 people, including 63 per cent contractual workers, 3.1 per cent women and 0.07 per cent persons with disabilities. Women in key managerial roles earned 26.8 per cent less than men, while median pay for women workers fell 11.1 per cent in FY25 as men’s pay increased. Worker injuries rose 36.5 per cent to 359, and fatalities increased from 17 to 22, with workers accounting for more than 90 per cent of deaths.
iFOREST recommended cement-specific reporting guidance, standardised metrics, mandatory production disclosure and third-party verification. It also called for environmental, social and governance policies to be integrated into business strategies and implemented more effectively on the ground.
Ambuja Cements expects its sales volumes to grow faster than the cement industry during the second half of fiscal year 2027, as it seeks a recovery in institutional demand after a weak first half. The Gautam Adani-owned company is aiming to rebuild volumes while protecting profitability.
The company reported a 90 per cent year-on-year decline in consolidated net profit attributable to owners of the parent to Rs. 1.93 bn for the quarter ended 30 September, from Rs. 17.74 bn a year earlier. The previous year’s profit included a reversal of income-tax provisions worth Rs. 16.97 bn. Revenue from operations rose marginally to Rs. 91.66 bn from Rs. 91.3 bn.
Trade volumes increased 8.6 per cent year-on-year in the September quarter, but weaker institutional sales left overall volumes broadly unchanged. Ambuja Cements expects both trade and institutional sales to turn positive in the third and fourth quarters. Trade sales are made through dealers and distributors, while institutional or business-to-business sales involve bulk supplies to infrastructure developers, government projects and real estate companies.
The company had earlier reduced institutional sales that did not generate adequate returns. It now plans to rebuild the business selectively, while continuing to prioritise trade sales and higher-value products. Trade accounted for 74 per cent of sales in the quarter, up six percentage points from a year earlier, while premium products increased to 37 per cent of trade sales from 35 per cent. Blended cement’s share rose to 82 per cent from 77 per cent.
Ambuja Cements commissioned 4.6 mn t of capacity during the quarter. Another 3.2 mn t at Bathinda in Punjab and Jodhpur has stabilised, with the facilities expected to ramp up in the second half. A further 2.4 mn t facility at Varkala in Bihar is scheduled for commissioning during the period. Higher fuel and logistics costs remain a challenge, while the company has realised a cement price increase of about Rs. 10 per bag in October and is targeting operating costs of Rs. 4,250 per t for the full year.
