Madhusudan Rasiraju, Country Head, IKN India, talks about enhancing cement plant efficiency with energy-saving, reliable, and customised solutions while supporting sustainability through innovations like oxy-fuel plants and AFR adaptability.

Could you explain what IKN Engineering is, what the company specialises in, and share insights about your clinker cooling solutions?
IKN is a Germany-based company that specialises in providing advanced clinker cooling solutions to the cement industry. Our expertise lies in developing and supplying innovative cooling systems that focus on energy efficiency, durability and cost-effectiveness.
The clinker cooling process is a critical stage in cement production, as it significantly influences the energy efficiency of the entire plant. Our coolers are designed with cutting-edge technology to recuperate a substantial amount of heat from the clinker. This recovered heat is redirected back into the cement production process, enabling our customers to reduce their fuel consumption significantly. Moreover, IKN coolers are engineered for reliability. They are built to operate with minimal maintenance, which helps to lower operational costs and reduce downtime. By focusing on high performance and long-term reliability, we ensure that our solutions are both economically and environmentally beneficial.

How does IKN contribute to improving the efficiency of cement plant operations and supporting sustainability goals?
IKN plays a pivotal role in enhancing the operational efficiency of cement plants while aligning with global sustainability objectives. Historically, clinker coolers required frequent maintenance, with intervals as short as five to six months. This led to regular shutdowns, which disrupted operations and increased costs. With IKN’s advanced cooling solutions, cement plants can now operate their coolers for extended periods without significant maintenance. Our coolers are not only more reliable but also consume less power, which directly reduces energy costs. Additionally, the high heat recuperation efficiency of our systems ensures that less fuel is required for the cement-making process, contributing to a lower carbon footprint.
Sustainability is embedded in our solutions. By reducing energy consumption, optimising processes, and minimising maintenance, we help our customers achieve their operational goals while supporting their commitment to environmental stewardship.

What role does technology play in the clinker cooling process, and how does IKN leverage it to provide advanced solutions?
Technology is the cornerstone of clinker cooling and a driving force behind our innovative solutions at IKN. The cement industry’s needs are constantly evolving, and to stay ahead, we ensure our technologies remain dynamic and adaptable. We adopt a customer-centric approach, continuously collecting feedback from our clients to improve our systems. Every clinker cooler we supply is tailored to meet the specific requirements of the plant it serves. For instance, the physical layout, production capacity, and operational challenges of each facility are unique, and we ensure our solutions address these specific needs.
Moreover, our ongoing research and development efforts focus on enhancing reliability, improving heat recovery, and lowering energy consumption. By integrating the latest technological advancements, we make sure our coolers set new benchmarks in performance and sustainability.

Do you offer customised solutions for each cement plant, and how does the increasing use of alternative fuels (AFR) impact your clinker cooling solutions?
Absolutely, customisation is at the core of what we do at IKN. In the case of retrofits, every cooler is custom-designed to fit the specific layout and operational needs of the existing cement plant. For new installations, we collaborate closely with our clients to design coolers that are precisely sized and configured to meet their requirements.
Regarding alternative fuels (AFR), their increasing use in cement plants presents unique challenges. AFR often results in the production of finer clinker, which can be more difficult to handle during the cooling process. To address this, we optimise the operating parameters of our coolers, such as airflow density and cooler speed, to ensure they perform effectively with the type of clinker being produced. This adaptability ensures that our coolers remain efficient and reliable, even in plants using diverse and non-traditional fuels.

What challenges do you face in providing clinker cooling solutions, both from your operations and from the cement industry’s perspective?
Challenges are inevitable in any advanced technological field, and clinker cooling is no exception. One of the primary challenges we face is adapting to the changing demands of our customers. For example, frequent shifts in fuel types or the introduction of AFR can disrupt the cooling process. These changes often result in variations in clinker properties, requiring us to make adjustments to maintain optimal performance. Additionally, the grid surfaces in coolers may face increased wear and tear due to these changes. At IKN, we address such challenges by reinforcing the grid surfaces and fine-tuning our systems to handle these dynamic conditions.
From an industry perspective, there is an increasing emphasis on efficiency, sustainability, and cost reduction. Meeting these expectations while maintaining high performance is challenging, but it is a challenge we embrace through innovation, research, and collaboration with our clients.

What are your views on the net zero mission, and how is IKN contributing toward this goal?
The net zero mission is a vital initiative for energy-intensive industries such as cement, steel, and power. It requires a collective effort across the supply chain to achieve meaningful progress.
At IKN, we are committed to supporting this global goal. One of our key contributions is the development of oxy-fuel plants, which are designed to significantly reduce carbon emissions during production. We are also exploring innovative cooling methods, such as the use of nitrogen or other media, to further enhance sustainability. Currently, we have two oxy-fuel projects underway in Germany. These plants not only demonstrate our commitment to the net zero mission but also serve as examples of how advanced technology can drive sustainability in the cement industry. By focusing on durability, efficiency, and innovation, we help our clients reduce their environmental footprint while maintaining high operational standards.

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.

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.
