Shift Towards Sustainable Construction

Published

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.

India Sets Up First Carbon Capture Testbeds for Cement Industry

Five CCU testbeds launched to decarbonise cement production

Published

The Department of Science and Technology (DST) recently unveiled a pioneering national initiative: five Carbon Capture and Utilisation (CCU) testbeds in the cement sector, forming a first-of-its-kind research and innovation cluster to combat industrial carbon emissions.
This is a significant step towards India’s Climate Action for fostering National Determined Contributions (NDCs) targets and to achieve net zero decarbonisation pathways for Industry Transition., towards the Government’s goal to achieve a carbon-neutral economy by 2070.
Carbon Capture Utilisation (CCU) holds significant importance in hard-to-abate sectors like Cement, Steel, Power, Oil &Natural Gas, Chemicals & Fertilizers in reducing emissions by capturing carbon dioxide from industrial processes and converting it to value add products such as synthetic fuels, Urea, Soda, Ash, chemicals, food grade CO2 or concrete aggregates. CCU provides a feasible pathway for these tough to decarbonise industries to lower their carbon footprint and move towards achieving Net Zero Goals while continuing their operations efficiently. DST has taken major strides in fostering R&D in the CCUS domain.
Concrete is vital for India’s economy and the Cement industry being one of the main hard-to-abate sectors, is committed to align with the national decarbonisation commitments. New technologies to decarbonise emission intensity of the cement sector would play a key role in achieving of national net zero targets.
Recognizing the critical need for decarbonising the Cement sector, the Energy and Sustainable Technology (CEST) Division of Department launched a unique call for mobilising Academia-Industry Consortia proposals for deployment of Carbon Capture Utilisation (CCU) in Cement Sector. This Special call envisaged to develop and deploy innovative CCU Test bed in Cement Sector with thrust on Developing CO2 capture + CO2 Utilisation integrated unit in an Industrial set up through an innovative Public Private Partnership (PPP) funding model.
As a unique initiative and one of its first kind in India, DST has approved setting up of five CCU testbeds for translational R&D, to be set up in Academia-Industry collaboration under this significant initiative of DST in PPP mode, engaging with premier research laboratories as knowledge partners and top Cement companies as the industry partner.
On the occasion of National Technology Day celebrations, on May 11, 2025 the 5 CCU Cement Test beds were announced and grants had been handed over to the Test bed teams by the Chief Guest, Union Minister of State (Independent Charge) for Science and Technology; Earth Sciences and Minister of State for PMO, Department of Atomic Energy, Department of Space, Personnel, Public Grievances and Pensions, Dr Jitendra Singh in the presence of Secretary DST Prof. Abhay Karandikar.
The five testbeds are not just academic experiments — they are collaborative industrial pilot projects bringing together India’s top research institutions and leading cement manufacturers under a unique Public-Private Partnership (PPP) model. Each testbed addresses a different facet of CCU, from cutting-edge catalysis to vacuum-based gas separation.
The outcomes of this innovative initiative will not only showcase the pathways of decarbonisation towards Net zero goals through CCU route in cement sector, but should also be a critical confidence building measure for potential stakeholders to uptake the deployed CCU technology for further scale up and commercialisation.
It is envisioned that through continuous research and innovation under these test beds in developing innovative catalysts, materials, electrolyser technology, reactors, and electronics, the cost of Green Cement via the deployed CCU technology in Cement Sector may considerably be made more sustainable.
Secretary DBT Dr Rajesh Gokhale, Dr Ajai Choudhary, Co-Founder HCL, Dr. Rajesh Pathak, Secretary, TDB, Dr Anita Gupta Head CEST, DST and Dr Neelima Alam, Associate Head, DST were also present at the programme organized at Dr Ambedkar International Centre, New Delhi.
