Shift Towards Sustainable Construction

Neeraj Akhoury, CEO India Holcim and Managing Director and CEO, Ambuja Cements, draws a clear path for sustainable shift towards blended cement, which would lead to lesser use of clinker, thereby enabling the industry to reach its decarbonisation targets.

In today’s world, cement stands shoulder to shoulder with core sectors like steel, energy and others as one of the key building blocks to nation building. With the current market size of $325 billion, the cement industry (in GDP terms) would rank among the top 50 industrialised nations in the world today. By 2028, this market is expected to grow to $460 billion. And when that happens, the global cement industry would have raced past another dozen or more countries in GDP terms.
Leaders in the cement sector across the world are not only aware of the opportunity this represents, but the weight of the responsibility that comes with it. Almost all major cement producers have committed themselves to a Net Zero future, an important decarbonisation movement that has also taken the larger industrial world by storm.

Planning Ahead
In the cement sector, we have identified every stage in the value chain as a potential target for decarbonisation. The execution of this change is happening within the bigger framework of ‘Circular Economy’. In simple terms, the principles of circular economy pushes manufacturers to treat every material (natural and processed) to be used in perpetuity. A key element in this system is the ability to cut down or reduce as one of the three Rs, along with reuse and recycling to achieve long term sustainability.
For the cement sector, one of the focus areas has been reduction of the use of clinkers in the manufacturing process, or what in industry parlance is called ‘clinker factor’. Clinker is an intermediary material used in the production of cement.
The reduction of clinker factor is achieved by replacing it with alternative blending materials like pozzolana, slag or fly ash (industrial waste) to produce blended cements. This reduces the carbon intensity of the cement—a primary lever for reduction of carbon emissions.
So, the more we shift towards blended cement, the lesser will be the use of clinker and thus move the cement industry closer to its ultimate decarbonisation targets.
The growing demand for blended cement in a country like India is particularly very effective in combating climate change. India is today the second-largest cement producer and consumer, with the share of blended cement of around 75 per cent of our total production mix. However, India’s per capita cement consumption at around 235 kg is less than half of the global average (520 kg).

Surging Demand
The economic growth we are foreseeing over the next few years and decades including the target of becoming a $5 trillion GDP will push the demand for cement to much higher levels. The surge in demand for cement can be environmentally sustained only by our efforts to push for wider use of blended and green cement. From the manufacturers point of view such a shift is already gaining a lot of momentum through more investment in R&D-led innovation to improve products and processes and in no small measure a strong and consistent consumer-focussed advocacy.
As one of the leading markets for cement in the world, this is an historic opportunity for India to establish its leadership in the true sense of the word.

The building materials industry is projected to grow by 8-12 per cent over the next five years. How is Aparna Enterprises positioning itself to leverage this momentum and solidify its market presence?

The Indian construction and building materials industry is projected to witness significant expansion, with estimates suggesting an 8-12 per cent compound annual growth rate (CAGR) over the next five years. This growth is fuelled by rapid urbanisation, increased infrastructure investments and sustainability-focused policies. With India’s real-estate market expected to reach $ 1 trillion by 2030, the demand for high-quality building materials is at an all-time high.

The Government of India’s flagship programmes, such as PM Gati Shakti, the Smart Cities Mission and the Housing for All (PMAY-Urban) initiative, are key drivers of this surge. The infrastructure sector alone is expected to receive a budgetary push of over Rs 11 trillion in FY25, with enhanced capital expenditure allocation.

At Aparna Enterprises, we are proactively aligning with this momentum through capacity expansion, product diversification, and cutting-edge technological integration.

Our key strategic priorities include:

Expanding operations in high-growth regions across Tier-2 and Tier-3 cities, ensuring access to quality building materials nationwide
Investing in automation, AI-driven quality control systems and digital integration, enhancing efficiency and precision in manufacturing
Scaling up production capabilities in our RMC, tiles, uPVC and other divisions to meet the anticipated surge in demand.

Start-ups worldwide are invited to contribute to the global cement and concrete industry’s efforts to reduce CO2 emissions and combat climate change. The Global Cement and Concrete Association (GCCA) and its members are calling for applicants for the Innovandi Open Challenge 2025.

Now in its fourth year, the Innovandi Open Challenge aims to connect start-ups with GCCA members to develop innovations that help decarbonise the cement and concrete industry.

The challenge is seeking start-ups working on next-generation materials for net-zero concrete, such as low-carbon admixtures, supplementary cementitious materials (SCMs), activators, or binders. Innovations in these areas could help reduce the carbon-intensive element of cement, clinker, and integrate cutting-edge materials to lower CO2 emissions.

Thomas Guillot, GCCA’s Chief Executive, stated, “Advanced production methods are already decarbonising cement and concrete worldwide. Through the Innovandi Open Challenge, we aim to accelerate our industry’s progress towards net-zero concrete.”

Concrete is the second most widely used material on Earth, and its decarbonisation is critical to achieving net-zero emissions across the global construction sector.
