Ganesh W Jirkuntwar, Senior Executive Director and National Manufacturing Head, Dalmia Cement (Bharat) talks about technology and alternative fuels, which are important tools in the cement industry’s march towards reduction of carbon footprint.

Dalmia Cement Bharat has evolved to create a distinct identity for itself that is synonymous with sustainability and growth. The philosophy of ‘Clean and Green is Profitable and Sustainable’ has helped the company deliver on the expectations of its stakeholders. As a champion of blended cement, it is rapidly gaining popularity as a ‘green’ alternative to the traditional Ordinary Portland Cement in the construction sector. Three levers are being used to decarbonise the cement. Uses of supplementary cementitious materials like fly ash and slag have reduced clinker consumption and hence reduced carbon footprint in cement. Alternative fuels (green fuel) like industrial wastes, renewable biomass, municipal wastes etc., have reduced consumption of fossil fuel facilitating in achieving carbon neutrality. Increased dependence on renewable power sources like solar, waste heat recovery systems, wind power etc., is also helping the company achieve its goal of becoming the second green cement manufacturer.
Alternative fuels to the tune of 20 per cent by heat substitution are being used, putting it far ahead of any other Indian cement manufacture in uses of alternative fuel. Dalmia Cement Bharat wants to lead and drive the industry’s shift towards a sustainable use of alternative fuel in cement production by investing in requisite technology and machineries, and setting an ambitious target of achieving 35 per cent TSR by FY25. It uses industrial wastes, municipal wastes, agricultural wastes etc., as alternative fuel, which otherwise goes either into a water source or landfill and creates environmental issues. The use of these industrial wastes is a great example of a circular economy ecosystem.

Reducing the Carbon Footprint
Uses of alternative fuels and raw materials is helping the company fast-track its journey of achieving carbon negative. Dalmia carbon footprint at 467 kg CO2/tonne of cement (specific net CO2) is one of the lowest in the cement sector globally. Since the announcement of the carbon negative ambition in 2018, the specific carbon footprint has reduced by more than 9 per cent in the Scope 1 category and it is currently at 12.55 million tCO2/year. By reducing the scope 1 GHG emissions to 32 per cent per ton of cementitious material by FY ’34, they have also reduced overall scope 2 emissions by 30 per cent and are targeting to reduce scope 2 GHG emissions to 61.9 per cent per tonne of cementitious material by FY’34. Both these are on FY ’19 as base year and within the same timeframe validated by SBTi.

Role of Technology
Technology plays a pivotal role in determining the quantum of alternative raw materials and fuels to be used without compromising properties of cement. Online sampling, online particle size analyser, robotic lab etc., are great enablers for determining composition of alternative raw materials and fuels to be used. Nowadays digital technology is also facilitating in generating lots of insights from process data, which is helping in taking real-time basis decisions on desired composition of alternative raw materials and alternative fuels for achieving targeted quality of clinker and cement.
Cement making process has not undergone major overhaul since inception of dry cement making process, therefore basic chemistry and machinery are pretty much standardised across the industry. Cement composition is decided based on end uses and does not depend on plant machinery per say. Plant machineries are upgraded for switching to newer and efficient designed machines, replacing the old and obsolete machines etc. Plant machinery upgradation is a situational call in Dalmia and is decided based on group guidelines for reliability, technology adoption, ROA etc.

Alternative Fuels and Profitability
Cement producers worldwide are striving to lower their production costs. One effective method of achieving this end is the use of alternative fuels. Use of low-grade alternative fuels such as sewage sludge, biomass fuels such as wood products, agricultural wastes, etc. in precalciners is a viable option because combustion in a precalciner vessel takes place at a lower temperature.
Alternative fuel uses have been quite beneficial for us not only in terms of improving bottom-line but also helping gain tall recognition at the international stage. During peak fossil fuel prices, its uses helped reduce the spend on fuel to great extent and optimise variable cost of cement. Despite having a handicap of regional presence, Dalmia Cement Bharat could beat pan India cement players on cost front as result of substantial uses of alternative fuels.
Usages of alternative fuels lead to marginal increase in overall heat consumption. In case preheater fans and other equipment are being used at its full capacity, usage of alternative fuels may result in marginal reduction of clinker throughput.
Similarly, uses of alternative raw materials may impact cement quality, if not proportioned carefully.
Alternative fuel uses in Indian cement kilns is at the cusp of transformational change. Almost all cement players are adopting traditional technology and installing necessary infra for using alternative fuels in kilns. Uses of alternative fuel in kilns are limited by its chloride and ash contents. These issues are being taken care of by industry wide research and piloting of technologies, which has potential to reduce chloride and ash contents from alternative fuels. Various technologies for preprocessing of alternative fuels like pyrolysis, pyrorotor etc. are being piloted in India.
Government bodies, academia, industry bodies etc. are also doing extensive research on uses
of alternative raw materials for decarbonising cement.

Higher capex, city-led growth and CCUS funding improve demand visibility and decarbonisation prospects for cement

Mumbai

Cement manufacturers have welcomed the Union Budget 2026–27’s strong infrastructure thrust, with public capital expenditure increased to Rs 12.2 trillion, saying it reinforces infrastructure as the central engine of economic growth and strengthens medium-term prospects for the cement sector. In a statement, the Cement Manufacturers’ Association (CMA) has welcomed the Union budget 2026-27 for reinforcing the ambitions for the nation’s growth balancing the aspirations of the people through inclusivity inspired by the vision of Narendra Modi, Prime Minister of India, for a Viksit Bharat by 2047 and Atmanirbharta.

The budget underscores India’s steady economic trajectory over the past 12 years, marked by fiscal discipline, sustained growth and moderate inflation, and offers strong demand visibility for infrastructure linked sectors such as cement.

The Budget’s strong infrastructure push, with public capital expenditure rising from Rs 11.2 trillion in fiscal year 2025–26 to Rs 12.2 trillion in fiscal year 2026–27, recognises infrastructure as the primary anchor for economic growth creating positive prospects for the Indian cement industry and improving long term visibility for the cement sector. The emphasis on Tier 2 and Tier 3 cities with populations above 5 lakh and the creation of City Economic Regions (CERs) with an allocation of Rs 50 billion per CER over five years, should accelerate construction activity across housing, transport and urban services, supporting broad based cement consumption.

Logistics and connectivity measures announced in the budget are particularly significant for the cement industry. The announcement of new dedicated freight corridors, the operationalisation of 20 additional National Waterways over the next five years, the launch of the Coastal Cargo Promotion Scheme to raise the modal share of waterways and coastal shipping from 6 per cent to 12 per cent by 2047, and the development of ship repair ecosystems should enhance multimodal freight efficiency, reduce logistics costs and improve the sector’s carbon footprint. The announcement of seven high speed rail corridors as growth corridors can be expected to further stimulate regional development and construction demand.

Commenting on the budget, Parth Jindal, President, Cement Manufacturers’ Association (CMA), said, “As India advances towards a Viksit Bharat, the three kartavya articulated in the Union Budget provide a clear context for the Nation’s growth and aspirations, combining economic momentum with capacity building and inclusive progress. The Cement Manufacturers’ Association (CMA) appreciates the Union Budget 2026-27 for the continued emphasis on manufacturing competitiveness, urban development and infrastructure modernisation, supported by over 350 reforms spanning GST simplification, labour codes, quality control rationalisation and coordinated deregulation with States. These reforms, alongside the Budget’s focus on Youth Power and domestic manufacturing capacity under Atmanirbharta, stand to strengthen the investment environment for capital intensive sectors such as Cement. The Union Budget 2026-27 reflects the Government’s focus on infrastructure led development emerging as a structural pillar of India’s growth strategy.”

He added, “The Rs 200 billion CCUS outlay for various sectors, including Cement, fundamentally alters the decarbonisation landscape for India’s emissions intensive industries. CCUS is a significant enabler for large scale decarbonisation of industries such as Cement and this intervention directly addresses the technology and cost requirements of the Cement sector in context. The Cement Industry, fully aligned with the Government of India’s Net Zero commitment by 2070, views this support as critical to enabling the adoption and scale up of CCUS technologies while continuing to meet the Country’s long term infrastructure needs.”

Dr Raghavpat Singhania, Vice President, CMA, said, “The government’s sustained infrastructure push supports employment, regional development and stronger local supply chains. Cement manufacturing clusters act as economic anchors across regions, generating livelihoods in construction, logistics and allied sectors. The budget’s focus on inclusive growth, execution and system level enablers creates a supportive environment for responsible and efficient expansion offering opportunities for economic growth and lending momentum to the cement sector. The increase in public capex to Rs 12.2 trillion, the focus on Tier 2 and Tier 3 cities, and the creation of City Economic Regions stand to strengthen the growth of the cement sector. We welcome the budget’s emphasis on tourism, cultural and social infrastructure, which should broaden construction activity across regions. Investments in tourism facilities, heritage and Buddhist circuits, regional connectivity in Purvodaya and North Eastern States, and the strengthening of emergency and trauma care infrastructure in district hospitals reinforce the cement sector’s role in enabling inclusive growth.”

CMA also noted the Government’s continued commitment to fiscal discipline, with the fiscal deficit estimated at 4.3 per cent of GDP in FY27, reinforcing macroeconomic stability and investor confidence.

Going forward, domestic steel mills are targeting capacity expansion
of nearly 40 per cent through till FY31, adding 80-85 mt, translating
into an investment pipeline of $ 45-50 billion. So, Jhunjhunwala points
out that continuing the safeguard duty will be vital to prevent a surge
in imports and protect domestic prices from external shocks. While in
FY26, the industry operating profit per tonne is expected to hold at
around $ 108, similar to last year, the industry’s earnings must
meaningfully improve from hereon to sustain large-scale investments.
Else, domestic mills could experience a significant spike in industry
leverage levels over the medium term, increasing their vulnerability to
external macroeconomic shocks.(~$ 60/tonne) over the past one month,
compressing the import parity discount to ~$ 23-25/tonne from previous
highs of ~$ 70-90/tonne, adds Jhunjhunwala. With this, he says, “the
industry can expect high resistance to further steel price increases.”

Domestic HRC prices have increased by ~Rs 5,000/tonne
“Aggressive
capacity additions (~15 mt commissioned in FY25, with 5 mt more by
FY26) have created a supply overhang, temporarily outpacing demand
growth of ~11-12 mt,” he says…
