Ganesh W Jirkuntwar, Senior Executive Director & National Manufacturing Head, Dalmia Cement (Bharat) Limited, analyses the effects of raw materials on emission and efforts taken by his company to conserve the environment.

Tell us about the efforts taken by your organisation to better the environment in and around the manufacturing unit.
Our company has taken a number of efforts to better the environment in order to maximise the proportion of blended cement in our product basket, promote the usage of alternative supplementary cementitious materials recommended by IS for cement and increase the usage of alternative fuels.
We have also installed the appropriate systems to co-process wastes judiciously and follow a pre-processing system for alternative fuels. We have implemented a waste heat recovery system and are now able to tap into solar energy.

How does the use of environmentally friendly fuels or raw materials impact the profitability of the organisation?
Dalmia Bharat Limited follows the business philosophy of ‘Clean & Green is Profitable and Sustainable.’ By using environmentally friendly fuel and raw materials, we have managed to create an impact on our triple bottom line: social, environmental as well as financial performance. A proper strategy for selection and adopting environment-friendly initiatives that act as fuel and raw materials is expected to significantly boost the organisation’s profitability.
Large volumes of legacy municipal waste are available at various municipal dump sites, that can be converted to Refuse Derived Fuel (RDF) and can be used by Indian cement Industries. Cement industries are currently facing a tough time due to the steep rise in fuel prices. The usage of RDF and other alternative fuels will help the cement industry in optimising its fuel cost.

Tell us about the types of blended cement and their composition manufactured by your organisation. How does the strength of blended cement differ from OPC?
At Dalmia Cement (Bharat) Limited, we manufacture PPC, PCC and PSC as blended cements. The composition of blended cements is decided strictly in accordance with BIS norms.
The overall strength of blended cement is comparable with OPC 43 Grade. However, Indian Specification (IS) recommends that blended cement should meet the strength Norms of OPC 33 Grade.

What are the key supplementary materials used to manufacture blended cement?
The key supplementary materials used to manufacture blended cement are pulverised fuel ash, known as flyash, and granulated slag.

Tell us about the impact blended cement creates on the environment.
Blended cement has higher durability and better resistance towards the aggressive environment of chloride and sulphate. Additionally, less clinker is being consumed to produce the same volume of cement, resulting in raw materials savings, energy savings (thermal and electrical), reduced CO2 emission and waste utilisation.

How does the use of alternative fuels impact the productivity and efficiency of the manufacturing process?
The use of alternative fuels leads to a marginal increase in overall heat consumption. In case a preheater fan and other equipment are being used at their full capacity, usage of alternative fuels may result in a marginal reduction of clinker throughput.

What role does technology play in creating blends that help curb emissions and make the environment better?
Technology helps reduce CO2 emission as a result of low clinker consumption in blended cement compared to non-blended cement.

What are the major challenges your organisation is facing to curb the emission rate?
Although cement manufacturing is an energy-intensive process, during clinker manufacturing, the emission of process CO2 is inevitable. The only way to curb the emission significantly as of now helps replace fossil fuels with alternative fuels.
The major challenges in increasing the usage of alternative fuels include adopting RDF which is the only alternative fuel and is available in large volumes. However, the quality of RDF being supplied in India is very poor and inconsistent. Additionally, high ash content and moisture in RDF restrict the higher usage of RDF.
In India, the use of alternative fuel is at a very nascent stage and cement players need to invest in R&D on understanding its impact on cement and corrective actions

How do you foresee the future of emissions created by the cement industry?
The cement industry is putting in unrelenting efforts to reduce the Cement Clinker Ratio (CC Ratio), higher usage of alternative fuels and increased the usage of renewable energy. This will reflect in their carbon footprint figure in the next few years. We expect that, in a few years, newer technological adoption such as carbon capture, green hydrogen usage, rotodynamic heater etc. will also decide the future of emissions by cement industries.

UltraTech Cement’s Kukurdih Cement Works in Chhattisgarh has met 100 per cent of its electricity requirement through green energy every month since April 2026. Commissioned in 2024, the integrated cement manufacturing unit has an installed grey cement capacity of 3.3 million tonnes per annum.

The plant meets its electricity requirement through a combination of renewable power sourcing and Waste Heat Recovery Systems (WHRS). UltraTech said the combination enables the unit to meet its power needs through green energy while maintaining operational reliability.

Since April 2026, nearly a third of UltraTech’s 76 manufacturing units in India have maintained green energy utilisation above 50 per cent of their electricity requirement. Five units, including Kukurdih, have exceeded 95 per cent green energy utilisation.

The company is also progressively deploying Battery Energy Storage Systems (BESS) across its manufacturing network to support greater integration of renewable energy. UltraTech said it has not invested in new captive thermal power capacity at its integrated units, including greenfield projects and brownfield expansions, for more than 10 years.

As of Q1FY27, UltraTech’s captive green energy capacity stood at 1,897 MW, comprising 1,463 MW of renewable capacity from solar, wind and hybrid sources, and 434 MW of WHRS capacity.

Under its RE100 commitment, the company aims to increase the share of green power in its total power mix to 85 per cent by 2030 and 100 per cent by 2050.

Cement Prices Rise Rs. 7 per Bag in September; October Hikes Expected

Cement prices rose in September as companies weighed further increases.

Cement companies may seek to raise prices by Rs. 5 to Rs. 20 per bag across most markets in October, although the ability to sustain the increases will depend on demand recovery and dealer acceptance, according to a report by Centrum Broking. The outlook follows a pickup in pricing momentum during September after largely stable prices in July and August.

The all-India average trade price increased by Rs. 7 per bag month-on-month to Rs. 356 in September. Centrum Broking’s channel checks indicated gains across both trade and non-trade segments, with non-trade prices recording sharper increases in most markets. However, higher company billing rates were not fully passed on to customers in several regions because dealers continued selling at earlier prices to meet quarter-end volume targets.

The brokerage said demand weakness in Q2FY27 was less pronounced than the usual seasonal trend, with construction activity improving in several markets towards the end of the quarter. Demand remained range-bound across several markets in July and August, while September produced mixed regional trends. Higher rainfall affected activity in some areas, whereas lower rainfall supported construction work elsewhere.

South India recorded the largest price increase in September, at Rs. 11 per bag, followed by West India at Rs. 9. Central, East and North India each reported increases of Rs. 5 per bag. Despite the September recovery, the average all-India trade price for Q2FY27 stood at Rs. 351 per bag, down Rs. 1 sequentially, as weaker pricing in July and August offset the later gains.

Centrum Broking said the success of any October increases would depend on the pace of demand recovery and dealers’ willingness to accept higher prices. Fuel prices have also risen sharply in recent weeks, making the implementation and sustainability of price increases a key factor for the cement industry’s pricing outlook.

The Andhra Pradesh government has approved a greenfield cement project worth Rs. 30 bn by My Home Industries, along with incentives of up to Rs. 11.29 bn. The decision comes amid a political controversy in Telangana involving allegations about landholdings associated with My Home Group.

According to an Industries and Commerce Department order issued on September 25, 2026, the project is expected to create 2,000 jobs and begin commercial production by March 2029. The proposed facility will have capacity to produce 3.5 MTPA of clinker and 3.5 MTPA of cement.

The total investment includes fixed capital investment of Rs. 25.97 bn, pre-operative expenses of Rs. 2.23 bn, contingencies of Rs. 1.26 bn and working capital margin of Rs. 540 mn. The incentive package is capped at Rs. 11.29 bn, equivalent to up to 43.48 per cent of fixed capital investment, subject to completion of the committed investment by March 2029.

The package includes a capital subsidy of 39 per cent of eligible fixed capital investment, capped at Rs. 9.43 bn, payable over 10 years from the start of commercial production. It also provides reimbursement of Rs. 1 per unit on electricity purchased from distribution companies for 10 years, subject to a ceiling of Rs. 1.86 bn. A further incentive equivalent to 2 per cent of fixed capital investment is linked to the creation of the committed jobs and other policy conditions.

The state has approved the allotment of 27.19 acres through the Andhra Pradesh Industrial Infrastructure Corporation at actual cost. The project also involves land linked to two temples and the realignment of a canal across approximately 9.93 acres, with conditions requiring alternative temple facilities and company-funded infrastructure work. Telangana Chief Minister A. Revanth Reddy has separately raised allegations concerning land associated with My Home Group, including 2,463 acres near Shamshabad. The allegations remain subject to verification through official records and any investigations.
