Changing fuel policies and stricter boiler safety norms have given rise to demand for advanced boiler systems that offer energy efficiency and flexibility in the same package. Only those who can offer specialised designs, backed by a solid design and development team, are successful in the market. Shridhar Nambi, Director & Chief Executive Officer, Greenesol Power Systems, elaborates on how the market is warming up to new boiler technologies. Excerpts from the interview.

What is the range of boiler technologies offered by you in terms of capacity and fuel flexibility?

We offer a pulverised coal fired boiler with capacity upto 1080 TPH for any kind of coal, lignite with subcritical pressure. We offer CFBC from 35 TPH to 800 TPH subcritical pressure for fuels like coal rejects, washers rejects, Dolochar, Indian coal, Indonesian coal, Indian lignite, biomass and sludge.

Apart from this, we offer municipal solid waste fired boilers upto 600 T/D infiltration for power production and Heat Recovery Steam Generator (HRSG) behind gas turbine frame 9SA. We also supply Waste Heat Recovery boilers (WHRB) behind kilns for steel industries, cement industries and coke oven plants.

How has boiler technology evolved to meet the needs of the cement industry?

Cement industries being located in remote areas, may not always have grid connectivity. Such companies have to rely on captive power generation using diesel based generator.

Rising costs of fuel oil has made coal based systems more attractive. Companies are now opting for advance technologies like AFBC, CFBC with ash generation, which can be blend into cement directly. Boiler technology has evolved with time to meet the changing needs of the country.

What are the latest innovations in boiler design that can improve energy efficiency?

Installing WHRB is a critical improvement for cement industries trying to achieve better energy efficiency. The technology has matured sufficiently and we have tested it in many nations.

How is changing fuel policy affecting the boiler manufacturing business?

Changing fuel policies lead to variation in fuel price fluctuations. Being tied up with a system that runs on only one type of fuel is no longer an economically viable option. Today, boilers are being designed to be compatible with different types of domestic and imported coal like Indonesian coal, Australian coal and other countries. The industry is looking for systems that offer flexibility. One such option is the CFBCs technology.

What are the major factors that reduce the boiler’s lifecycle and reliability?

If the boiler is designed for a specific type of fuel is run on a different fuel due to logistics or economic reasons, then the boiler’s lifecycle will be significantly affected.

It will also impact the reliability of the systems performance.

Where do customers usually go wrong while picking up boilers?

End users at times go wrong while planning the lifecycle duration of the boiler. Apart from this, often users go for boilers compatible with fuel available at low prices and fail to foresee price fluctuations in the future. Prices may fluctuate and it is a good idea to go for systems compatible with different fuel types.

Hence, it is very important to plan availability of fuel in the long run depending on the geographical location and other such factors.

Where do Indian cement manufacturers stand when it comes to predictive maintenance of boilers?

Normally, manufacturing of the main product will be the key focus of the production staff, while issues like regular maintenance take the back seat. Regular predictive maintenance of boilers, though, is an requirement IBR but priority is not given to it.

Which are the new challenges and opportunities in boiler design and manufacture?

Boiler design is more than satisfying the standard designing requirements. One has to deliver more than the standard requirements and often customise the design as per the requirements. A good design must ensure best returns on investment.

Boiler efficiency is a measure of how much combustion energy is converted into steam energy, while steam quality measures how much liquid water is present in the steam produced. Steam pressure reduction has the potential to save fuel consumed by a steam system. The amount of capital investment may be minimal for the appropriate application of this efficiency measure. The amount of fuel that can be saved varies with the design and maintenance of the existing system. Steam pressure reduction should be tested to establish the critical minimum pressure at a steam load that is above average but below peak. This will provide an estimate of savings.

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.

On the occasion of World Environment Day, industry leaders reaffirmed their commitment to supporting India’s climate goals while delivering the materials required for resilient, durable and sustainable infrastructure.

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.
