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.

Nuvoco Vistas Corp. Ltd., one of India’s leading building materials companies, has reported its highest-ever second-quarter consolidated EBITDA of Rs 3.71 billion for Q2 FY26, reflecting an 8% year-on-year revenue growth to Rs 24.58 billion. Cement sales volume stood at 4.3 MMT during the quarter, driven by robust demand and a rising share of premium products, which reached an all-time high of 44%.

The company continued its deleveraging journey, reducing like-to-like net debt by Rs 10.09 billion year-on-year to Rs 34.92 billion. Commenting on the performance, Jayakumar Krishnaswamy, Managing Director, said, “Despite macro headwinds, disciplined execution and focus on premiumisation helped us achieve record performance. We remain confident in our structural growth trajectory.”

Nuvoco’s capacity expansion plans remain on track, with refurbishment of the Vadraj Cement facility progressing towards operationalisation by Q3 FY27. In addition, the company’s 4 MTPA phased expansion in eastern India, expected between December 2025 and March 2027, will raise its total cement capacity to 35 MTPA by FY27.

Reinforcing its sustainability credentials, Nuvoco continues to lead the sector with one of the lowest carbon emission intensities at 453.8 kg CO? per tonne of cementitious material.

Jindal Stainless Limited has announced an investment of $150 million to build and operate a new wet milling plant in Jajpur, Odisha, aimed at doubling its capacity to recover metal from industrial waste. The project is being developed in partnership with Harsco Environmental under a 15-year agreement.

The facility will enable the recovery of valuable metals from slag and other waste materials, significantly improving resource efficiency and reducing environmental impact. The initiative aligns with Jindal Stainless’s sustainability roadmap, which focuses on circular economy practices and low-carbon operations.

In financial year 2025, the company reduced its carbon footprint by about 14 per cent through key decarbonisation initiatives, including commissioning India’s first green hydrogen plant for stainless steel production and setting up the country’s largest captive solar energy plant within a single industrial campus in Odisha.

Shares of Jindal Stainless rose 1.8 per cent to Rs 789.4 per share following the announcement, extending a 5 per cent gain over the past month.

Vedanta Limited has received approval from the Competition Commission of India (CCI) to acquire Jaiprakash Associates Limited (JAL) for approximately Rs 17,000 million under the Insolvency and Bankruptcy Code (IBC) process. The move marks Vedanta’s strategic expansion beyond its core mining and metals portfolio into cement, real estate, and infrastructure sectors.

Once the flagship of the Jaypee Group, JAL has faced severe financial distress with creditors’ claims exceeding Rs 59,000 million. Vedanta emerged as the preferred bidder in a competitive auction, outbidding the Adani Group with an overall offer of Rs 17,000 million, equivalent to Rs 12,505 million in net present value terms. The payment structure involves an upfront settlement of around Rs 3,800 million, followed by annual instalments of Rs 2,500–3,000 million over five years.

The National Asset Reconstruction Company Limited (NARCL), which acquired the group’s stressed loans from a State Bank of India-led consortium, now leads the creditor committee. Lenders are expected to take a haircut of around 71 per cent based on Vedanta’s offer. Despite approvals for other bidders, Vedanta’s proposal stood out as the most viable resolution plan, paving the way for the company’s diversification into new business verticals.
