It is necessary to demystify the concept of green and sustainable housing, writes Anil Banchor.

India ranks second as the country with the largest number of green buildings after the US. Most of the Indian projects have demonstrated through their simplicity that green buildings and sustainable construction are not complex or high-tech ventures. In particular the retrofitting of old buildings demonstrates that it is an easy procedure which can be replicated with ease to transform scores of old buildings in the country?s cities and towns.

The difference in a green building is in the approach to its design, which focuses on a concern for extending the life span of natural resources; reducing operating costs such as for use of energy and water; providing human comfort, safety and productivity. Other typical features would include the use of non-toxic, recycled and environmental friendly building materials.

Analysts estimate the differential cost to be no more than 3-5 per cent. If you factor in savings of 25-30 per cent in the water and electricity consumption bill in an average green building in India, the additional expense is not just recovered within five years but such buildings can be profitable.

In spite of these facts most green buildings in India are non-residential commercial structures concentrated in a few of the big cities and the common man still sees such homes as a luxury. Therefore, it is necessary to demystify the concept of Green and Sustainable Housing.

There are several smart green building materials which are cost effective and long lasting available for the modern home owner which would help them build or rebuild their homes, as a more eco-friendly and sustainable habitat. Traditional construction materials now have greener and smarter substitutes such as:

Replace natural sand with finely powdered crystalline silica made from rejected limestone. It helps in replacing natural sand usage in concrete and plastics. It also ensures a comparatively denser concrete than those made only with natural sand and quarry fines resulting in a significant increase in compressive strength and durability. Using this alternative also aides in preserving natural reserves and protecting the environment.

Replace clay bricks with a more eco-friendly, technically superior, fly ash-based composition. They are superior in quality than any other bricks available in the market in terms of strength, water absorption, efflorescence and various other parameters. Apart from the quality and mechanical properties, fly ash-based bricks are energy and resource efficient bricks produced using cleaner production techniques and reduce carbon footprints.

The third important component is concrete, the versatility of which is yet to be properly explored. It can be customised to serve several purposes. Some of these are: Let concrete weather-proof your house: A mix of concrete which makes use of Portland Cement to a higher extent with cement materials without replacing any other important properties has a higher durability compared to OPC against external weathering loses. This special composition increases the concrete?s resistance to sulphates, reduces chloride ion penetration, and improves resistance to aggressive environments.

Concrete can now be used to beautify: Concrete need not always be mundane, it can be printed or stamped for making decorative surfaces on porch, paving, footpath and walkways. Whether, the driveway to a garage or a poolside private access path, this product can help add a new colour to a mundane surroundings.

Concrete can self-drain water: High performance concrete is available which is porous within its body to permit water drainage to lower surface, thus improving ground water table. It allows drainage of water, the large pores present in the no-fines concrete allow easy drainage in to ground under appropriate conditions. It helps keep the area dry and clean and prevents warm and polluted water from entering our streams. It enables more efficient land developments.

Concrete can reduce your electricity bills: Concrete is now designed to provide thermal comfort in the premises. A layer of customised concrete can be applied over the top layer of the roof slab, so that the heat or cold is not directly allowed inside the building. This kind of arrangement keeps the building cool in summer and warm in winters. The trapped insulation in the concrete layer provides a bed for energy control in the cement. Energy consumption is reduced to a great extent due to this mechanism.

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.
