Paul Baruya, Director of Strategy and Sustainability, FutureCoal, suggests that the next decade will determine whether CCUS scales from demonstration to a mainstream pathway for net-zero cement.

Cement forms the essential foundation of modern infrastructure—homes, roads, ports, hospitals, wind turbine bases, and transmission pylons. It is also one of the most challenging industrial products to decarbonise at scale. That’s why carbon capture, utilisation and storage (CCUS)—has shifted from a “nice to have” to a strategic necessity for many credible net-zero pathways.
Annual carbon dioxide (CO2) emissions from cement are around 1.6 Gt worldwide and could more than double by 2050. To many, decarbonisation involves replacing fuels, but cement differs: a significant portion of its emissions comes from chemical processes rather than fuel combustion.
Cement’s climate footprint is significant. Global cement production totals around 4 billion tonnes per year, produced across more than 3,100 plants worldwide. At this scale, even relatively modest emissions intensity results in substantial absolute emissions. As a result, cement production is widely estimated to account for around 7–8 per cent of global CO2 emissions.
A key step in cement production is the creation of clinker, an intermediate product that is ground into cement. Clinker forms by heating limestone (calcium carbonate), which breaks down into lime (calcium oxide) and releases CO2. Even with a kiln powered entirely by zero-carbon electricity, the calcination process will still emit CO2.
FutrureCoal’s Sustainable Coal Stewardship explores solutions for fossil fuel users. For example, clinker substitution using coal fly ash can significantly reduce emissions; however, it cannot eliminate the chemical release of CO2. CCUS is one of the few mature options capable of substantially removing the remaining CO2.
The IPCC considers cement a “hard-to-abate” sector. In its Sixth Assessment Report (AR6), it states that CCS is crucial to eliminate calcination emissions, which account for 60 per cent of GHG emissions in modern cement plants (IPCC). Worldwide, CCUS will deliver two-thirds of cement sector emissions reductions by mid-century (CemNet+1).

Decarbonisation is not simple, there are four considerations:

Both energy use and chemistry drive emissions, where calcination is intrinsic to conventional clinker production (hence the IPCC’s emphasis on CCS).\
Kilns operate at high temperatures of 1,450°C; electrifying heat is theoretically possible but difficult to retrofit and expensive at today’s scale.
Plants are long-lived assets that last for decades; replacement cycles are slow, so retrofits and add-ons (such as CCS) become vital.
Cement is a low-margin bulk material. A slight cost increase per tonne matters in competitive markets—yet deep decarbonisation raises costs before policy and procurement catchup.

No single capture technology fits all plants, a variety is needed. These methods begin with proven post-combustion capture, then incorporate advanced, process-specific, and next-generation technologies as plants develop, energy systems decarbonise, and transport and storage infrastructure expand.

A mine-based post-combustion capture is the most advanced, already operating at a commercial scale. It captures CO2 from flue gases after combustion and calcination, making it suitable for retrofitting, but it is energy-intensive.
Oxyfuel combustion burns fuel in pure oxygen, producing a CO2-rich exhaust that is easier to capture, although it requires major modifications to the kiln and consumes significant energy for oxygen production.
Calcium looping leverages lime’s natural affinity for CO2, suitable for cement but complex and not widespread. Technologies like LEILAC capture CO2 during calcination with high purity and lower energy use, but they still require clean energy or additional methods to reach net zero.

Global cement demand is strongly connected to urbanisation, infrastructure development, and housing. Mature markets may plateau, while emerging markets can experience rapid growth.

India: A major decarbonisation opportunity
India is central to the global cement transition for three reasons: scale, growth trajectory, and the policy imperative to reconcile development with climate commitments.
The US Geological Survey (USGS) estimates India produced ~420 Mt in 2023 and ~450 Mt in 2024. That makes India one of the world’s largest producers, with continued capacity additions expected as infrastructure and housing demand grow.
Cement accounts for approximately 7–8 per cent of global CO2 emissions and around 5.8 per cent of India’s CO2 emissions in 2022, (GCCA). As India works toward its 2070 net-zero target, carbon capture, utilisation and storage (CCUS) will be an important component of its longer-term decarbonisation pathway.
India also highlights a broader reality: cement decarbonisation cannot rely on a single solution. Instead, it will require a combination of measures, likely including:

Lower clinker-to-cement ratios and supplementary cementitious materials,
Alternative fuels and efficiency,
For deep abatement, carbon capture for the remaining process emissions.

Challenges for CCS in cement
Carbon capture at cement plants is technically feasible, but still faces significant practical and economic challenges:
A challenging gas stream: Cement flue gas contains CO2 along with impurities and exhibits variable flow and temperature conditions. Capture units (amines, membranes, calcium looping, oxyfuel, etc.) need to be integrated carefully to avoid disrupting kiln operations.
Energy penalty and heat management: Many capture systems require significant energy, such as steam for solvent regeneration. Providing that energy without merely shifting emissions elsewhere is a design challenge; it encourages plants to research and develop low-energy solutions, waste heat recovery, blending low-carbon fuels, or all of the above.
Space constraints and retrofit limitations: Older plants may lack the physical footprint for large-scale capture equipment, compression, liquefaction, and CO2-handling infrastructure—especially in land-constrained industrial clusters.
Transport and storage are not “at the factory gate”: Even if capture is successful, you still need pipelines, shipping terminals, injection wells, permits, monitoring, and long-term liability frameworks. Cement CCS progresses most quickly where shared CO2 infrastructure is in place.
This is why projects increasingly cluster around hubs and why policy support and shared infrastructure are often the difference between pilot and commercial deployment.

Examples of the latest carbon capture on cement plants
A few projects demonstrate where the sector currently stands, progressing from pilots and studies into first-wave industrial deployment.
Brevik CCS (Norway): Heidelberg Materials inaugurated Brevik CCS in mid-2025, described as the world’s first industrial-scale CCS facility in the cement industry, designed to capture ~0.4 Mt CO2per year (Heidelberg Materials). CO2 will be shipped to Norway’s Northern Lights storage facility and the capture volume will equal half the plant’s total emissions at full capture (Reuters). Brevik is a blueprint to demonstrate end-to-end integration from capture to storage.
Padeswood (UK): Heidelberg’s cement plant at Padeswood has its CCS project construction slated to start in 2025 and net-zero cement production targeted for 2029 (Reuters). This underscores how public funding and CO2 infrastructure (Liverpool Bay storage) can unlock investment timelines.
LEILAC (Belgium): The EU-supported LEILAC project at Heidelberg Materials’ Lixhe cement plant in Belgium is testing a novel approach that targets process emissions rather than combustion emissions. The pilot facility is designed to capture approximately 18,000 tonnes of CO2 per year, with the follow-on LEILAC-2 phase exploring pathways to scale the technology toward commercial deployment (CINEA).
North America: In the United States, Holcim’s Ste. Genevieve cement plant has completed a front-end engineering and design (FEED) study assessing commercial-scale carbon capture, targeting up to 95 per cent of total CO2 emissions using an Air Liquide capture technology (OSTI). While not every FEED study progresses to a final investment decision, these projects provide important insight into where cement-sector carbon capture could realistically be heading.
India is exploring multiple technical approaches instead of a single solution. The country’s strategy involves government-backed testbeds to reduce risks in real-world plant conditions and industry roadmaps that show CCS/CCUS is essential for deep emission cuts. The Indian government is establishing five CCU testbeds in the cement industry through a public–private partnership (ETInfra.com+1). It focuses on hubs and storage options as enabling infrastructure to develop at scale (GCCA). India has launched a first-of-its-kind cluster of five CCU testbeds for the cement sector, organised as academia–industry pilots under a PPP model (ETInfra.com+1) including:

A pilot that captures CO2 via oxygen-enhanced calcination and converts it into lightweight concrete blocks and olefins (Ballabhgarh, Haryana, with JK Cement / NCCBM), and
A demonstration of carbon-negative mineralisation that locks CO2 into solid minerals (IIT Kanpur + JSW Cement) (ETInfra.com)
These testbeds aim to show the real-world performance of capture and utilisation options—capture rates, product quality, energy needs, operability, and integration with kiln systems—before scaling up to full commercial units.

Why the “hubs + storage” framing matters for India? Capture at plant level is only part of the solution: meaningful scale also relies on gas transport, permanent storage, and the development of CO2 hubs (Clean Energy Ministerial+1). This hub approach is particularly relevant because it can:

Reduce unit costs through shared compression/transport infrastructure,
Concentrate on early projects where storage/transport is most feasible, and
Give financiers confidence that captured CO2 has a viable end-point (storage or durable utilisation) rather than becoming stranded.

The bottom line
Cement is a foundational material with a fundamental climate challenge: process emissions that cannot be eliminated through clean energy alone. The IPCC is clear that, absent a near-term replacement of Portland cement chemistry, CCS is essential to address the majority of clinker-related emissions. With global cement production at around 4 gigatonnes (Gt) and still growing, cement decarbonisation is not a niche undertaking, it is a large-scale industrial transition.
The emergence of operational projects such as Brevik, the expansion of hub-linked initiatives across Europe, and a growing pipeline of pilots and front-end engineering studies indicate that the sector is beginning to move from ambition to execution. The coming decade will be decisive in determining whether CCS remains a premium, limited pathway, or becomes a mainstream industrial standard for delivering net-zero cement.

Roundtable discussions focus on innovation for safer highways.

Held on 12 March 2026 at Courtyard by Marriott, Mumbai, alongside the Infrastructure Today Airport Conclave, the RAHSTA Roundtable brought together stakeholders from across the highways and infrastructure ecosystem to shape the agenda for the 16th RAHSTA 2026, scheduled for 8–9 July 2026 at the Jio Convention Centre, Mumbai. The session focused on key industry themes including road construction, technology, safety and long-term sustainability.

Opening the discussion, Pratap Padode, Founder, FIRST Construction Council, said the roundtable marked the beginning of a broader consultative process leading up to the July event. The aim, he noted, is to bring together industry stakeholders to refine the agenda for discussions on the future of roads, bridges, tunnels and allied infrastructure.

Padode noted that while central road project awards have slowed in recent years, states are increasingly driving the next phase of infrastructure growth. Maharashtra, with its long-term road development plans and agencies such as MSRDC and MSIDC, is expected to play a significant role in this expansion.

RAHSTA Expo 2026 as a specialised platform dedicated to road infrastructure, covering highways, tunnels, bridges and flyovers along with construction technologies, safety systems and maintenance solutions. He also highlighted the growing importance of rural connectivity and said the organisers are engaging with government bodies to highlight rural road development initiatives.

Tanveer Padode, CIO, ASAPP Info Group, presented insights from IMPACCT, the group’s infrastructure intelligence platform. He pointed to a strong project pipeline despite slower highway awards earlier in the year, noting that states such as Maharashtra, Odisha and Arunachal Pradesh are emerging as key drivers of new projects. The data also revealed that only a small group of contractors participates in large-value infrastructure bids.

Lt Gen Rajeev Chaudhary, former Director General, Border Roads Organisation and Chairman of the RAHSTA Expo Committee, emphasised the need for stronger collaboration across the ecosystem, including policymakers, contractors, technology providers and financiers. He also called for addressing systemic issues within the sector and encouraged greater participation of women in infrastructure leadership.

The discussion also explored the evolving economics of road development. Phani Prasad Mandalaparthy, Associate Director, CRISIL Intelligence, noted that the slowdown in project awards reflects a shift towards higher-value logistics corridors rather than simple road widening projects. However, private participation through BOT and TOT models remains limited.

From the contractors’ perspective, Sudhir Hoshing, Whole-Time Director, Ceigall, said companies are becoming more selective in bidding, favouring projects with clearer payment mechanisms and efficient processes. While NHAI continues to offer greater operational clarity, states such as Uttar Pradesh and Bihar were cited as relatively supportive environments for project execution.

Durability and sustainability also emerged as key themes. Himanshu Agarwal, COO – Road & Infrastructure, Zydex Group India, highlighted the need to prioritise lifecycle performance and resilient pavements, while participants discussed the potential of alternative materials such as plastic waste, steel slag and industrial by-products in road construction.

Dr LR Manjunatha, Vice President, JSW Cement, emphasised that India has abundant fly ash, slag and other industrial materials that can improve durability and sustainability if integrated into specifications and policy frameworks.

Technology and equipment challenges were also discussed. Dr Lakshmana Rao Mantri, Dy General Manager, Afcons Infrastructure, highlighted the shortage of tunnel boring machines (TBMs), which is delaying several underground infrastructure projects. Participants agreed that developing domestic TBM manufacturing capabilities will be critical for future infrastructure expansion.

The future of concrete pavements was another area of discussion. Dr V Ramachandra, President, Indian Concrete Institute, stressed that the debate should focus on lifecycle performance rather than material choice alone, noting that evolving design standards are improving the feasibility of concrete roads.

Prof Dharamveer Singh of IIT Bombay added that while India has made significant progress in infrastructure development, stronger capacity building and better execution practices are essential to ensure consistent road quality.

The discussion also touched upon technology adoption in the sector. Rushabh Mamania, Partner & CBO, Roadvision, highlighted the growing role of AI in road infrastructure, noting that AI-driven monitoring systems are already being deployed across large stretches of national highways.

Overall, the roundtable underscored that the future of highway infrastructure will depend not only on the pace of construction but also on durability, safety, technology integration and sustainable materials. The discussions offered valuable insights that will help shape the agenda for RAHSTA 2026 and guide future collaboration within the industry.

CTS Roundtable Maps Technology Roadmap for Construction

Ahead of the Construction Technology Show (Con Tech Show) 2026, industry leaders, technology innovators and academia came together in Mumbai to deliberate on how digitalisation, automation and industrialised construction can reshape the sector. The discussion made one thing clear: construction can no longer afford to treat technology as optional.

Held on 12 March 2026 at Courtyard by Marriott, Mumbai, alongside the Infrastructure Today Airport Conclave, the CTS Roundtable served as a precursor to the Construction Technology Show 2026, scheduled for 19–20 August 2026 at NESCO, Mumbai.

A platform to move from discussion to deployment

Opening the session, Pratap Padode, Founder and Editor-in-Chief, ASAPP Info Global Group, said construction technology has long remained close to his heart, especially given the sector’s traditionally slow pace of technology adoption. He noted that over the years, the Construction Technology Summit had steadily built interest, and the next step was now to expand it into a larger, more meaningful platform that could bring together technology providers, users, startups and innovators under one roof.

Padode said the vision for CTS is not limited to software alone. The platform aims to embrace all forms of technology that can improve construction efficiency, quality and execution—from digital tools and project management systems to lean construction, off-site fabrication and startup-led innovation. He also highlighted plans to deepen startup participation and create space for young companies to showcase emerging construction solutions.

Industry at a turning point

Moderating the roundtable, Naushad Panjwani, Chairman, Mandarus Partners, set the context by pointing out that the global construction industry, despite being a multi-trillion-dollar sector, continues to lag in productivity. He noted that while manufacturing has consistently improved efficiency, construction has remained slow to modernise.

Referring to both global and Indian trends, Panjwani underlined that the industry is now at a decisive moment. India, he said, is entering a major build cycle, and delivering the next phase of infrastructure and real estate growth through traditional methods alone is no longer viable. The goal of the roundtable, therefore, was not to debate technology in isolation, but to identify the most critical conversations that would bridge the gap between innovation and implementation.

His central message was clear: CTS 2026 must be shaped around themes that make CEOs, CIOs and CTOs feel they cannot afford to miss the event.

From BIM to AI, data to governance

A major theme that emerged through the discussion was the need for better data, better visibility and better decision-making. Dr Venkata Santosh Kumar of IIT Bombay echoed this, saying that the underlying data infrastructure itself needs attention. Construction projects, particularly remote ones, often face issues around connectivity, data collection and data use. Without this foundation, more advanced technologies cannot deliver their full value.

Chandra Vasireddy, CEO & Co-founder, Inncircles, expanded the discussion to governance, arguing that technology must help connect the many moving parts of a construction business. For him, the real value of digital transformation lies in creating better governance, clearer visibility and stronger business outcomes.

Tejas Vara of Inncircles stressed the importance of timely site data for leadership teams, especially in large and remote projects where decisions on materials, machinery and manpower often get delayed because information does not reach headquarters in time.

The role of AI also featured prominently. Rushabh Mamania, Partner and CBO, Roadvision said that while AI and machine learning are now common terms, vision intelligence and language intelligence have still not deeply penetrated the construction sector. He emphasised that startups in India are building relevant AI-led solutions and are already attracting international interest, showing that innovation need not be imported—it can be built locally and scaled globally.

Industrialised construction gains ground

The roundtable also placed strong emphasis on industrialised construction methods. Kalyan Vaidyanathan, CTO – Construction & R&D, Tvasta, called for greater focus on off-site fabrication and the broader industrialisation of construction. Bhargav Jog, General Manager, Dextra, highlighted precast technology and alternative sustainable materials as areas with immediate relevance.

Several participants agreed that modular, precast and pre-engineered approaches are no longer niche ideas. They are increasingly becoming practical responses to the sector’s challenges around labour shortage, timelines, quality control and predictability.

Anup Mathew, Sr VP & Business Head, Godrej, argued that the industry needs a fully integrated approach—from design and procurement to execution and asset management. Unless these are connected, technology adoption will remain fragmented and sub-optimal. He pointed to pre-engineered and modular systems as examples of how industrial thinking can compress timelines, improve quality and reduce dependence on difficult on-site conditions.

Adoption remains the biggest hurdle

While there was broad agreement on the promise of technology, the discussion repeatedly returned to one fundamental challenge: adoption.

Abhishek Kumar, COO, LivSYT, observed that the market is crowded with solutions, but many buyers still struggle to evaluate which technology suits which use case. According to him, the industry needs clearer frameworks to help users select, compare and adopt solutions, rather than expecting a single platform to solve every problem.

Dr Tenepalli JaiSai, Associate Professor, School of Construction(SoC), NICMAR University, noted that isolated technologies will not solve the productivity problem by themselves. What is required is an integrated Construction 4.0 approach, where digital, physical and cyber-physical systems work together rather than in silos.

That concern around silos was reinforced by Subodh Dixit, former Director, Shapoorji Pallonji, who said the issue is not just that technologies are disconnected, but that stakeholders are as well. Clients, consultants, contractors and partners often operate with different priorities. Unless these silos are broken, technology will struggle to percolate across the full project value chain.

Harleen Oberoi, Project Management, Tata Realty shared a practical perspective from the client side, saying that successful BIM implementation requires investment across the ecosystem, not just within one organisation. Trade partners, vendors and other stakeholders must also be trained and aligned if the technology is to deliver its intended results.

Beyond buzzwords

A notable takeaway from the session was that the industry is moving past the phase of treating technology as a buzzword. Participants repeatedly stressed that the real question is not whether technology should be used, but where it creates measurable value and how that value can be scaled.

The conversation also expanded beyond mainstream themes to include repairs and rehabilitation, construction and demolition waste, sustainability, circular economy, green sourcing, carbon measurement, design interoperability, generative design, robotics, and the role of horticulture and greener built environments.

Setting the agenda for CTS 2026

By the close of the session, the roundtable had surfaced a strong set of themes for the upcoming show: BIM and digital twins, AI and data platforms, industrialised construction, startup innovation, governance-led technology adoption, robotics, sustainable materials, and integrated project delivery.

More importantly, the session established CTS 2026 as more than an exhibition. It is shaping up to be a serious industry platform where users, technology providers, researchers and policymakers can collectively define the future of construction.

As Padode noted in his closing remarks, the conversation will continue through further consultations and possibly webinars in the run-up to the show. If the roundtable is any indication, CTS 2026 will aim not merely to showcase technology, but to push the industry towards meaningful adoption at scale.

SEEPEX introduces BN pumps with Smart Joint Access (SJA) to improve efficiency, reliability, and inspection speed in demanding rock blasting operations.
Designed for abrasive and chemical media, the solution supports precise dosing, reduced downtime, and enhanced operational safety.

SEEPEX has introduced BN pumps with Smart Joint Access (SJA), engineered for the reliable and precise transfer of abrasive, corrosive, and chemical media in mining and construction. Designed for rock blasting, the pump features a large inspection opening for quick joint checks, a compact footprint for mobile or skid-mounted installations, and flexible drive and material options for consistent performance and uptime.

“Operators can inspect joints quickly and rely on precise pumping of shear-sensitive and abrasive emulsions,” said Magalie Levray, Global Business Development Manager Mining at SEEPEX. “This is particularly critical in rock blasting, where every borehole counts for productivity.” Industry Context

Rock blasting is essential for extracting hard rock and shaping safe excavation profiles in mining and construction. Accurate and consistent loading of explosive emulsions ensures controlled fragmentation, protects personnel, and maximizes productivity. Even minor deviations in pumping can cause delays or reduce product quality. BN pumps with SJA support routine maintenance and pre-operation checks by allowing fast verification of joint integrity, enabling more efficient operations.

Always Inspection Ready

Smart Joint Access is designed for inspection-friendly operations. The large inspection opening in the suction housing provides direct access to both joints, enabling rapid pre-operation checks while maintaining high operational reliability. Technicians can assess joint condition quickly, supporting continuous, reliable operation.

Key Features

Compact Footprint: Fits truck-mounted mobile units, skid-mounted systems, and factory installations.
Flexible Drive Options: Compact hydraulic drive or electric drive configurations.
Hydraulic Efficiency: Low-displacement design reduces oil requirements and supports low total cost of ownership.
Equal Wall Stator Design: Ensures high-pressure performance in a compact footprint.
Material Flexibility: Stainless steel or steel housings, chrome-plated rotors, and stators in NBR, EPDM, or FKM.

Operators benefit from shorter inspection cycles, reliable dosing, seamless integration, and fast delivery through framework agreements, helping to maintain uptime in critical rock blasting processes.

Applications – Optimized for Rock Blasting

BN pumps with SJA are designed for mining, tunneling, quarrying, civil works, dam construction, and other sectors requiring precise handling of abrasive or chemical media. They provide robust performance while enabling fast, reliable inspection and maintenance.With SJA, operators can quickly access both joints without disassembly, ensuring emulsions are transferred accurately and consistently. This reduces downtime, preserves product integrity, and supports uniform dosing across multiple bore holes.

With the Smart Joint Access inspection opening, operators can quickly access and assess the condition of both joints without disassembly, enabling immediate verification of pump readiness prior to blast hole loading. This allows operators to confirm that emulsions are transferred accurately and consistently, protecting personnel, minimizing product degradation, and maintaining uniform dosing across multiple bore holes.

The combination of equal wall stator design, compact integration, flexible drives, and progressive cavity pump technology ensures continuous, reliable operation even in space-limited, high-pressure environments.

From Inspection to Operation

A leading explosives provider implemented BN pumps with SJA in open pit and underground operations. By replacing legacy pumps, inspection cycles were significantly shortened, allowing crews to complete pre-operation checks and return mobile units to productive work faster. Direct joint access through SJA enabled immediate verification, consistent emulsion dosing, and reduced downtime caused by joint-related deviations.

“The inspection opening gives immediate confidence that each joint is secure before proceeding to bore holes,” said a site technician. “It allows us to act quickly, keeping blasting schedules on track.”

Framework agreements ensured rapid pump supply and minimal downtime, supporting multi-site operations across continents
