Rajesh Kumar Nayma, Associate General Manager – Environment and Sustainability, Wonder Cement, in conversation with Kanika Mathur about CCUS technology.

Wonder Cement Limited (WCL), a leading player in the cement industry, is committed to sustainable practices and innovation in its operations. Rajesh Kumar Nayma, Associate General Manager – Environment and Sustainability at WCL, shares insights into the company’s efforts to integrate Carbon Capture, Utilisation, and Storage (CCUS) technology to combat climate change. Through advanced processes and renewable energy initiatives, WCL is paving the way for a greener cement industry.

How is your company incorporating CCUS technology into its operations to promote sustainability?
To combat climate change and achieve Net Zero emissions by 2060, Carbon Capture, Utilisation, and Storage (CCUS) technology will play a pivotal role. Wonder Cement Limited (WCL) is actively collaborating with various technology providers to support this journey. Efforts include segregating greenhouse gas (GHG) emissions from stacks, implementing oxy-fuel technology, electrifying kilns, utilising 100 per cent solar energy within plants, and eliminating fossil fuel consumption.
WCL has conducted a comprehensive GHG inventory aligned with India’s COP26 commitments, aiming to achieve net-zero emissions. Technological innovations such as the installation of a 45 MW Waste Heat Recovery System (WHRS) and an additional 15 MW WHRB have been key milestones. These systems capture excess heat from production processes, converting it into energy and reducing carbon footprints. The company has also introduced advanced burner technology to lower NOx emissions and optimise energy consumption. Currently, WCL achieves less than 47 KWh/tonne of clinker and an SEC of less than 685 Kcal/kg of clinker—benchmarks among the best in the cement industry. These achievements reflect the company’s dedication to lowering environmental footprints through technological enhancements.

What challenges do you face in implementing CCUS in the cement manufacturing process, and how do you address them sustainably?
For India, CCUS is still an emerging concept. While some European companies have successfully implemented CCUS, the associated costs in the Indian context are currently prohibitive, approximately 2.5 to 3 times the cost of a cement plant. This makes large-scale implementation challenging. Some of the key challenges are:

  • High project costs: The cost of implementing CCUS is 2-3 times higher than the cost of a cement plant.
  • Energy-intensive operations: Operating CCUS facilities can double energy consumption, increasing operational expenses.
  • Space requirements: CCUS infrastructure demands substantial space.
  • Storage accessibility: Many Indian plants are located inland, far from oceans, complicating carbon storage options.

WCL is advocating for further research to optimise the utilisation of captured carbon, which could lower project and operational costs over time. The company is committed to exploring CCUS feasibility for its future projects and collaborating with technology providers to address these challenges sustainably.

How do you see CCUS contributing to achieving net-zero emissions?
CCUS is indispensable for achieving Net Zero emissions in the cement industry. Even with 100 per cent electrification of kilns and renewable energy utilisation, CO2 emissions from limestone calcination—a key raw material—remain unavoidable. The cement industry is a major contributor to GHG emissions, making CCUS critical for sustainability.
Integrating CCUS into plant operations ensures significant reductions in carbon emissions, supporting the industry’s Net Zero goals. This transformative technology will also play a vital role in combating climate change and aligning with global sustainability standards.

Any specific investments or partnerships made in CCUS research or deployment to support sustainable practices?
WCL has implemented several innovative technologies and process optimisations to minimise GHG emissions. Key initiatives include:

  • Installation of WHRS and maximising renewable energy usage.
  • Exploring the production of lower clinker cements such as LC3 and PLC, alongside increasing the share of blended cement like PPC.
  • Engaging with consultants and technology providers to develop a comprehensive Net Zero and ESG roadmap.

Any success stories or pilot projects involving CCUS that have significantly impacted your sustainability goals?
We have invested in renewable energy projects to significantly reduce its carbon footprint. Key examples include:

  • Solar power installations at Nimbahera Integrated Plant and Jhajjar Grinding Unit.
  • 15 MW windmills at Pratapgarh.
  • Renewable Power Purchase Agreements for grinding units in Aligarh, Uttar Pradesh, and Dhule, Maharashtra, replacing 50 to 60 per cent of energy demand from the grid and reducing GHG emissions.

The company is actively exploring CCUS installation for upcoming projects, assessing its viability in the Indian context.

Beyond CCUS, what other sustainable practices or innovations is your company implementing to reduce its environmental footprint?
WCL’s sustainability initiatives include:

Energy efficiency: Installing Variable Frequency Drives (VFDs), optimising differential pressures across bag filters, and enhancing kiln operations.

  • 3R principles: Emphasising reduce, reuse and recycle to optimise resource utilisation and waste management.
    Waste co-processing: Utilising over 50,000 tonnes of RDF/plastic waste and ensuring proper disposal of hazardous waste like used oil and lead-acid batteries.
  • Alternative raw materials: Substituting natural resources with industrial by-products like red mud, chemical gypsum and ETP sludge.
  • Plastic waste management: Increasing recycled content in PP bags and achieving Extended Producer Responsibility (EPR) targets.
  • Carbon sequestration: Planting over 250,000 trees, sequestering 5,000-10,000 tonnes of CO2 annually.
  • Water conservation: Operating as a water-positive organisation, with a focus on rainwater harvesting and groundwater recharge.

How do you balance the cost challenges of CCUS with your commitment to sustainable development?
WCL prioritises environmental stewardship alongside financial sustainability. While CCUS implementation involves high costs, WCL sees opportunities in mechanisms such as Carbon Border Adjustment Mechanism (CBAM), carbon trading, and Renewable Energy Certificate (REC) trading. These avenues provide financial incentives to offset the initial investment in green technologies.

World Environment Day spotlight on innovation and circularity

On World Environment Day, the Indian cement industry reiterated its commitment to supporting India’s climate ambitions through sustainable manufacturing, resource efficiency and the adoption of cleaner technologies.

The Cement Manufacturers’ Association (CMA) said the sector remains aligned with the Government of India’s Net Zero commitments and is accelerating efforts to reduce its environmental footprint while supporting the country’s infrastructure and development agenda.

Parth Jindal, President, CMA and Managing Director, JSW Cement, said the industry is increasingly adopting cleaner technologies, improving energy efficiency and expanding the use of alternative fuels and raw materials. He also highlighted the growing importance of circular economy practices, where industrial by-products and waste streams from one sector are utilised as resources in another.

“The Indian Cement Industry is aligned to the Government’s commitments on carbon mitigation and is accelerating the adoption of cleaner technologies, resource efficiency and circular economy practices while actively exploring the potential of Carbon Capture, Utilisation and Storage (CCUS) as a critical pathway for deep decarbonisation,” said Jindal.

He added that coprocessing industrial waste and by-products helps conserve natural resources, reduce disposal requirements and lower the environmental footprint across multiple sectors.

According to Jindal, sustainability is no longer limited to manufacturing processes but is increasingly influencing investment decisions, innovation strategies and long-term growth plans within the industry.

Echoing similar views, Dr Raghavpat Singhania, Vice President, CMA and Managing Director, JK Cement, said sustainable development extends beyond emissions reduction and must also focus on responsible resource utilisation and waste minimisation.

“Sustainability in the built environment cannot be measured by emissions alone. It is equally about how efficiently we use resources, how effectively we minimise waste and how responsibly we create the infrastructure that will serve future generations,” said Singhania.

He noted that the cement industry is advancing its sustainability agenda through greater resource efficiency, increased circularity, technological innovation and continuous improvements in manufacturing practices. As a key contributor to India’s infrastructure development, the sector has a critical role to play in balancing economic growth with environmental responsibility.

Environmental sustainability requires immediate action, not just long-term commitments and discussions. Recycling, circular economy practices, and technology-driven waste management can help industries reduce environmental impact while supporting sustainable growth.

Author: Jignesh Kundaria, Director and CEO, Fornnax Technology

World Environment Day serves as an important reminder that environmental sustainability can no longer remain confined to discussions, reports, or long-term commitments. The environmental challenges facing the world today demand immediate, measurable, and collective action. Across industries and communities, waste generation continues to outpace our ability to process it responsibly, placing increasing pressure on ecosystems, natural resources, public health, and the well-being of future generations.

One of the most significant shifts required today is a change in how society perceives waste. Rather than being viewed as a material to be discarded, waste must be recognised as a valuable resource that can contribute to both economic growth and environmental protection when managed through the right technologies and systems. This mindset forms the foundation of the circular economy model that countries across the world are increasingly adopting to reduce landfill dependence, recover valuable materials, and create more sustainable industrial ecosystems.

India has made meaningful progress in strengthening awareness around sustainability, recycling, and environmental responsibility over the past decade. Significant efforts are being made to formalise the recycling sector through improved infrastructure, technology adoption, policy implementation, and broader stakeholder participation. These developments are creating a stronger foundation for responsible waste management and resource recovery across the country.

However, achieving long-term environmental impact requires collaboration from all stakeholders. Industries, policymakers, technology providers, and communities must work together with greater accountability to strengthen recycling ecosystems, encourage responsible waste management practices, and create sustainable outcomes through consistent execution rather than temporary interventions.

As someone closely associated with the recycling industry, I firmly believe that technology will play a decisive role in addressing future environmental challenges. Advanced recycling systems have the potential to recover valuable resources, reduce pollution, minimise landfill burdens, and conserve energy, creating a more sustainable future for generations to come. This belief is deeply reflected in Fornnax’s motto, “Committed to Create a Green Future,” which embodies our commitment to building long-term environmental value through innovation and responsible action.

At the same time, technology alone cannot deliver meaningful change. Real progress requires intent, awareness, participation, and a shared sense of responsibility. Sustainable development can only be achieved when innovation is supported by collective action and a genuine commitment to environmental stewardship.

On this World Environment Day, let us move beyond conversations and take meaningful steps towards creating a cleaner, greener, and more sustainable planet. By embracing innovation, strengthening recycling ecosystems, and acting responsibly today, we can create lasting environmental impact and secure a better future for generations to come.

Dalmia Cement executed a Business Transfer Agreement with Jaiprakash Associates and Adani Infra, to acquire 5.2 MnTPA of cement capacity across Madhya Pradesh and Uttar Pradesh.

Dalmia Cement (Bharat) announced on May 22, 2026 that it had signed a Business Transfer Agreement with Jaiprakash Associates Limited and Adani Infra (India) Limited for the acquisition of cement plants located at Rewa in Madhya Pradesh and Churk, Chunar and Sadwa in Uttar Pradesh. The deal was struck at an enterprise value of ₹2,850 crore and is expected to close within two weeks of execution.

The acquired assets from Jaiprakash Associates include 5.2 MnTPA of cement capacity and 3.3 MnTPA of clinker capacity. The package also covers 99 MW of thermal power capacity and railway sidings at Rewa, Chunar, and a common siding at Churk. This infrastructure gives the acquisition immediate operational utility beyond just production tonnage.

The transaction has a long backstory. Dalmia Cement had originally entered into a framework agreement with Jaiprakash Associates in December 2022, covering the sale of these business assets along with a long-term clinker supply arrangement. However, before the deal could be completed, Jaiprakash Associates was admitted to insolvency proceedings under the Insolvency and Bankruptcy Code. The earlier agreements could not be consummated as a result.

In an official statement, Puneet Dalmia, Managing Director & CEO, Dalmia Bharat, said, “I am very excited about addition of these assets in our portfolio. This serves as a great strategic fit for Dalmia. It helps us move forward in our journey to be a pan India player and provide a strong head start to serve the high potential markets in Central region. I am optimistic that the expansion potential of these assets along with close proximity with Dalmia’s captive mines will help us create a capacity hub for the future”.

Following the approval of Adani Group’s resolution plan for Jaiprakash Associates under the IBC framework, Dalmia approached the new management to revive discussions. The fresh Business Transfer Agreement was executed to settle all pending disputes, legal proceedings, and arbitration matters arising from the original framework agreement with Jaiprakash Associates.

Expanding market reach

Dalmia added, “Our familiarity with these assets under the earlier tolling arrangement gives us a deep understanding of the facilities and helps us establish strong connect with channel partners and vendors. We believe that this will help us in faster ramp up of capacities and quicker inroads into the market. As we look forward, I am very confident that we will be able to leverage the strengths of Dalmia to operate these assets in a manner where we can maximise value creation for all our stakeholders.”

With the addition of these plants, Dalmia Bharat’s total installed cement capacity will rise to 54.7 MnTPA upon consummation. The company has further expansion projects underway at Belgaum, Pune, and Kadapa, which are expected to take overall capacity to 66.7 MnTPA by Q2 to Q3 FY28.

The Central India location of the Jaiprakash Associates plants gives Dalmia Bharat faster access to markets in Madhya Pradesh and Uttar Pradesh than a greenfield build would have allowed. The company also cited debottlenecking and brownfield expansion as near-term opportunities at the acquired sites. Dalmia Bharat said the assets were expected to contribute positively to EBITDA and overall returns, given the pricing environment in the region and the company’s cost structure.
