Sridhar S Sundaram, Vice President, Head of Global Product Line – Grinding and Gears, FLSmidth explains the role of technology in enhancing cement manufacturing processes to enable bigger and faster strides towards net zero targets.
Productivity growth through automation in the cement industry has grown from use of technology in the old physiological days to Artificial Intelligence (AI) powered softwares today. Cement plants operate in an automated way but there are still manual interventions that happen in an operating plant. These variations are also controlled now with AI powered softwares. This is helping customers have minimum manual intervention in the operation of the cement plants and increase production up to 5 per cent. However, when productivity increases, the energy consumption also decreases since the systems are automated to use only the optimum amount of energy. FLSmidth has an optimisation software called Process Expert Controller (PXC), which does the trick for cement manufactures and helps them enhance their production and productivity levels. Data is meant to enable better decision making. There is a control system, optimisation software and apart from these systems, there is also an application called Site Connect. Data from the control system is available at the head office in a monitor, tablet and mobile phone that enables better decision making and managerial interventions, which in due course of time better production and profits. This kind of digitalisation is at a nascent stage. The aim is to get as many plants connected as possible. Data from this software goes to the cloud, then back to the stakeholders i.e., FLSmidth headquarters, customer headquarters, and to all those who need the data to make better decisions. Work is also in progress on the backend algorithms for data collection. Based on these algorithms, there can be alarms, flags etc., enabling predictive interventions of plant maintenance.
No Alternative to Safety There are quite a few experts who have spoken about how to reduce CO2. OxyRich fuel and Green Hydrogen are the next generation topics as we exhaust the existing alternative fuel options. When we go from the present 15 per cent use of alternative fuels to 50 to 60 per cent use of alternative fuels, that itself will take care of the sustainability aspect of the cement industry. Beyond this, when CO2 capture is thought of then OxyRich and Green Hydrogen come into play. This technology is evolving and will eventually benefit all industries that have a high emission rate. The industry must use alternative fuels. Agriculture wastes can contribute up to 10 per cent of alternative fuels. Now, the industry is targeting 30 to 50 per cent use of alternative fuels, which comes out as waste derived fuels. Feedback that has come from the cement plants states that the odour and other problems associated with these fuels could be hazardous to the health. While it is encouraged for cement plants to use alternative fuels, the challenge is to safeguard every employee at the plant and surroundings with the other harmful effects of the waste derived fuels. The approach towards the use of waste derived fuels should be in a manner that all aspects of its use and safety should be taken care of before its implementation.
Technology at its best The industry has an intention to reduce its carbon footprint and make cement production friendly for the environment. However, without governance and regulation, the implementation will be a challenge and there will be no standard practice. If you go back 30 years when stacks in cement plants had a lot of dust, it was the government that made the norms and kept making them stricter, which has led to a highly reduced dust emission from cement plants. Similarly, usage of technology for reduction of carbon footprint will require intervention and regulation for cement players. In Europe, there is a penalty known as carbon tax while the talk of Indian industry is Sustainability Incentive. Either way, there needs to be an intervention to bring down emission levels in any industry.
Future Collaborations FLSmidth is always with its customers. And the company has a mission zero roadmap, too. The strategy and aim are to design a plant with zero emission by 2030. There are steps involved to this. The first step is to modernise old plants, which will have a huge impact on reducing carbon emission and energy consumption. Second step would be to collaborate with new technologies and make them available in the market in an accelerated manner. For this, a deal has been signed with Dalmia Cement that both companies will collaborate in pushing the sustainability agenda at a much larger scale than before. With Dalmia Cement as a partner, FLSmidth can immediately test its new technologies. Once that is successful, it can be taken to the market faster than before. The company is looking at partnerships with leading players to help bring better technology to the industry. Their role, too, is key in bringing a change and FLSmidth is looking forward to collaborating with all players of the Indian cement industry.

Crisil said operating margins of Indian cement manufacturers are expected to decline by Rs 50-75 per tonne (t) this fiscal to Rs 925-950 per t due to higher input costs triggered by the West Asia conflict. The analysis covered 18 cement companies accounting for nearly 90 per cent of India’s domestic cement capacity and noted margins had improved sharply to around Rs 1,000 per t in fiscal 2026.
Crisil noted that the reduction would be driven mainly by higher power and fuel costs, which account for about 30 per cent of total costs, as petcoke and imported coal prices have surged amid geopolitical uncertainties. Freight costs, which account for about a quarter of total costs, are also expected to remain elevated because of higher diesel prices. The impact on profitability is likely to be more pronounced in the first half of the fiscal year before easing commodity prices moderate cost pressures later.
The rating agency said steady domestic demand and strong balance sheets should keep credit profiles stable despite the moderation in margins. Green energy currently accounts for 35-40 per cent of the sector’s total electricity consumption and is expected to partly cushion higher energy costs. Operating cash flows are likely to remain resilient, supported by projected 6-7 per cent growth in cement demand this fiscal.
Crisil highlighted that demand growth will be driven primarily by infrastructure spending, which meets about one-third of sector consumption, and by a nearly 18 per cent higher budgetary allocation for core ministries that should support project execution. Weaker rural housing demand amid pressure on agricultural incomes from a possible below-average monsoon may be offset by improved urban housing demand supported by favourable home-loan rates and a strong pipeline of Pradhan Mantri Awas Yojana-Urban projects. Ongoing capacity additions will keep capital expenditure elevated and may lift net debt to EBITDA to between 1.2 and 1.4 times from around 1.0 time last fiscal, though ratios are expected to remain healthy.
UltraTech Cement’s board of directors has approved raising Rs 5,000 crore (Rs 50 bn) through non?convertible debentures issued in rupees.
The finance committee cleared a proposal to issue up to 500,000 fully paid, unsecured, listed, rated, redeemable, rupee?denominated, non?convertible, non?cumulative debentures of Rs 1 lakh each (Rs 0.1 mn each), aggregating to the Rs 5,000 crore programme.
As of June 2026 the firm reported net debt of Rs 15,875 crore (Rs 158.75 bn) and said its capacity expansion projects under execution are backed by capital expenditure of about Rs 17,000 crore (Rs 170 bn) over the next two to two?and?a?half years.
UltraTech spent Rs 9,500 crore (Rs 95 bn) on capital expenditure in financial year 2026 and in April the group crossed 200.1 mn tonnes per annum of domestic grey cement capacity and 205.5 mn tonnes per annum of global capacity.
The chief financial officer indicated the company would take consolidated capacity beyond 242 mn tonnes per annum, with grey cement capacity reaching 212.7 mn tonnes per annum by the end of financial year 2027. He noted the net debt?to?earnings before interest, taxes, depreciation and amortisation ratio stood at 0.87 times as of June 2026 and the company was confident of ending financial year 2027 with the ratio below one time.
In the first quarter of financial year 2026?27 UltraTech’s net profit attributable to owners rose 16.8 per cent year?on?year to Rs 2,599.3 crore (Rs 25.993 bn) and revenue from operations increased 15.9 per cent to Rs 24,648.20 crore (Rs 246.482 bn). The board approval is expected to complement internal cash flows as the company advances its expansion programme.
Andhra Pradesh Education and IT Minister Nara Lokesh on Wednesday laid the foundation stone for the Line-2 expansion of Dalmia Bharat Cement at Chinnakomerla village in Mylavaram Mandal in Kadapa district. The project carries an investment of Rs 31 billion (bn) and is slated for completion by the third quarter of the financial year 2028. The expansion is intended to boost industrial growth and employment generation across the Rayalaseema region.
Once commissioned, the Kadapa facility will become Dalmia Bharat’s largest integrated cement manufacturing ecosystem in southern India, creating over 1,000 direct and indirect jobs and opening new business avenues for regional micro, small and medium enterprises and transport operators. Lokesh said the expansion signalled growing corporate confidence in the state and reflected the practical ease of doing business that secured repeat investment.
He placed the project within the government’s wider economic targets and recalled the Yuvagalam padayatra commitment to generate two million (mn) jobs within five years, noting that the state would cultivate talent while industry created opportunities. Lokesh highlighted Andhra Pradesh’s competitive pursuit of major manufacturing accounts, mentioning past successes and a personal initiative to engage global investors when persuading them to anchor expansion in the state.
The plant will leverage Kadapa’s abundant limestone reserves to scale production and sustainability. Clinker capacity is planned to rise from two point five million tonnes per annum (mn tpa) to six point one mn tpa, while overall cement output will increase from three point six mn tpa to nine point six mn tpa. The unit is designed to operate on over eighty per cent renewable energy and deploy waste heat recovery, zero liquid discharge, water recycling and advanced AI systems to optimise efficiency. Industries Minister TG Bharat, BC Welfare Minister S. Savitha and Jammalamadugu MLA C. Adinarayana Reddy attended the ceremony.
