Challenging Days Ahead

Bad news never comes singly. India’s economic growth has slumped to its lowest in more than two years while output expansion at key industries tumbled to a six-year low and even the finance minister, Pranab Mukherjee, has warned that there are tough times ahead. There has been a sharp deceleration in industrial growth with output growth in eight core industries, including steel, cement and coal, dropping to near-zero in October, a sharp decline from 7.2 per cent one year back. Under the circumstances, the cement sector needs to remain vigilant and while bracing itself for weaker growth, seek out newer strategies to ensure that targeted capacity and production stays on line while staying in line with environmental demands and limitations in raw material availability.It is worrying indeed that fiscal deficit for the first seven months of the year has already reached 75 per cent of the year’s estimate. Experts concur with the finance minister that a combination of domestic and international issues are going to impact the country’s growth. GDP data released by the government on in the last week of November 2011 has revealed broad-based weakness in the economy, with mining contracting 2.9 per cent and manufacturing rising by 2.7 per cent in the last quarter. Despite the gloomy outlook, the finance ministry is hopeful that the economy will recover some of its lost momentum and is expecting 7.3 per cent GDP as against last year’s 8.5 per cent.According to Research & Markets report on the Indian cement sector, economic recovery, which had gained momentum in the first half of FY11, started showing signs of moderation in the second half. The biggest hindrance to growth momentum, however, has been high inflation. Inflation refuses to abate and has forced RBI to pursue monetary tightening measures even at the cost of growth. Rising energy prices and interest rates will continue to pose a challenge for businesses in the near future. Despite these short term challenges, the overall economic sentiment remains healthy and a good growth rate for the next year is expected.FY11 was quite challenging for the cement industry. On the one hand, demand growth weakened due to lower realty and infrastructure spending, while on the other, extended monsoons and logistical constraints dampened construction activity.On the supply front, overcapacity continued to plague the industry. During the year, the industry witnessed capacity addition of around 28 million TPA in addition to the 60 million TPA added in the previous year. Industry capacity utilization was at 75 per cent against 84 per cent recorded in the previous year. Surplus cement scenario together with sluggish demand and volatile prices adversely impacted domestic realizations which were lower by 4 per cent as compared to the previous year. On the cost front, the higher price of both domestic and imported coal resulted in a 25 per cent increase in energy costs, which rose substantially from 671 per ton to 838 per ton. During the year, imported coal prices rose by 36 per cent from CIF $ 89 per ton to $ 121 per ton. In addition to the normal price hike in domestic coal, there was a further increase in domestic coal prices in the range of 30 per cent -150 per cent from 1st March, 2011, according to the report.While the larger economic issues play out a crucial role on the industry’s performance, it is left to the sector to analyse the various other shortcomings it faces and seek remedies for the same.PRESENT STATUS

  • Capacity and Production:

The installed capacity of cement in the country has grown during the period 1991 to 2011 at an average rate of 8.3 per cent CAGR while the production has grown at the rate of 8 per cent during the same period. The table -1 gives the installed capacity and production of cement between 1991-2011.

  • Thermal Energy:

The weighted average of thermal energy consumption of major 26 plants is shown in figure – 1. It would be seen that very little improvement is made over the years between 2005-2006 to 2007-2008. The world’s best ranges between 680-690 Kcal/kg clinker. Though there are some cement plants in India which are able to fall in this category but industry as a whole has challenge before it to further improve on this account.

  • Electric Energy Efficiency:

The weighted average of consumption of electric energy of 26 plants is given in figure – 2. The electric consumption has virtually reached at plateau and showing very little further improvement. The best operated plants have brought down the consumption in the range of 65-68 kwh/t cement, however, industry as a whole has scope for further improvement. Environmental Performance of Cement Plants:The National Ambient Air Quality Requirement as per CPCB is given in table – 2.The modern cement plants are able to adhere to these norms. The new generation plants with capacity 8000TPD and above are even excelling the norms.

  • Product Mix:

The Indian cement industry has undergone major shift in product mix especially during the last decade. The environmental and sustainability issues may demand same trend to continue in the future. The table -3 gives product mix during the different periods;CHALLENGES AHEAD

  • Lime Stone:

Lime stone will continue to be the life line of cement manufacture. As per thumb rule, for every ton of clinker produced, 1.75 tonnes mineable line stone deposits of proven variety should be available. For 350 million tons installed targeted capacity by the end of XI plan (2012), nearly 600 mn.t of cement grade lime stone have to be made available annually. Keeping in view the rapid expansion of Indian Cement Industry, NCB initiated the task of preparation of national inventory of cement grade lime stone. As on 31st March, 2002, India’s total reserves have been estimated as given in table – 4.Table – 4 Lime Stone ReservesSizable reserves are located in inaccessible areas, difficult terrains reserved forests, bio-zones and coastal regulatory Zones, etc. The proven category reserves are only 22,476mn.t which are likely to last for next 35 to 40 years at the present rate of production.Apart from limited availability of measured reserve for green field projects, about 27 per cent of total reserves are of marginal grade which can only be utilized with sweetener or after up-gradation through beneficiation. Availability of cement grade limestone will be becoming a major challenge for the cement industry in the future.

  • Coal :

Availability of coal is proving another bottleneck in the growth of cement industry. The coal demand of cement industry is given in table -5.During the last decade the coal demand has gone almost four times. The infrastructure deficiencies at ports are causing problems in importing coal and availability of indigenous coal to cement industry is not assured. The first preference is being given to Thermal Power Plants and then to steel industry in allocation of coal by the Govt. The cost of coal is escalating every year and posing challenge before the cement industry. The situation is likely to aggravate in future.BLENDING MATERIALS

  • Fly Ash:

Large quality of fly ash is generated in India but in many cases, the location of major Thermal Power Plants is far away from cement plants and in absence of proper infrastructure for transportation and handing of fly ash, most of it cannot be utilized. The availability of fly ash is given in table – 6The cost of fly ash is continuously increasing due to transportation and permission given to thermal power plants to charge for it instead of giving free. The mega thermal plants located in East UP, West Bengal, North Bihar and generally in Eastern part of India have very few cement plants in close vicinity. The mismatch in location of Thermal Power Plants and cement plants is shown in Figure – 3The availability of good quality fly ash at reasonable cost is also going to be major factor before the cement industry in coming years.

  • GGBS

Ground Granulated Blastfurnace Slag (GGBS) cement is a by-product of the steel industry. Molten slag lying on top of the molten iron in the blastfurnace comprises silicates (glass), and is the raw material for GGBS cement. The molten slag – of no use to the steel making process – is cooled and then finely ground to form GGBS cement. Currently around 200 kg of slag is generated for each ton of steel produced in India making it 11 to 12 mt slag annually. Most of the slag is produced in the eastern part of the country where it is used in production of slag cement. The availability of blast furnace slag will continue to remain limited and possibilities need to be explored to use slags other than blast furnace like zinc slag, copper slag, steel slag for manufacture of slag cement. At present these slags are not permitted by BIS for production of slag cement.HIGH INPUT COSTS AND INFRASTRUCTURAL WEAKNESS

At present, the cement industry is facing two fold problems of high input costs and infrastructural weakness. The inputs with spiraling cost increase are coal, power and transport by rail or road. The coal from public sector is of poor quality, high ash and low calorific value content and at times costlier than imported coal. There is need to introduce competition for improving quality, regularity in supply and reduced prices. The power from public utilities is of poor quality due to frequent power cuts and fluctuating voltage. Power sector reforms if taken up seriously will enable quality power to cement plants at reasonable cost.Transport by rail or road is a cost-intensive component and amounts to almost 15 per cent to 20 per cent of the delivered cost to the consumers. The railway tariff is high and need to be rationalized for an essential product like cement. Road transport on the other hand, provides limited alternative because of inadequacy of road network and rising cost of road transport due to continuously rising fuel cost. Inland water transport is a low investment, eco-friendly and cheap mode especially for bulk commodities like cement. Coastal shipping and inland waterways will help in bringing down the transportation cost. Due to increasing use of cement in bilk, more and more bulk terminals will be needed in the years to come and inland water transport and coastal shipping can be of great help in this regard.TO INCREASE USE OF CEMENTCement is not the end-use product for the consumer. Concrete and mortar are the real end-products. Use of concrete at present is very low, about 0.5t per head annually against World’s average of 1.0t. Use of concrete and cement based products need to be promoted especially in the following sectors to increase the demand of cement.

  • Concrete roads
  • White topping over existing bitumen roads
  • Cement based bricks/blocks for walling in lieu of clay bricks
  • Pre-fab components for mass housing in lieu of conventional systems for roofing, flooring, walling etc.
  • Cement concrete lining to canals to reduce seepage losses.
  • Development of inland water ways and linking of rivers.

The average consumption of cement per head is very low in India, in the range of 180-190 kg while world average is about 400kg and in developed countries it is 600-800kg. Cement-concrete is more durable than other conventional materials and the use of concrete in construction will bring down the life cycle of civil works and will be more eco-friendly and sustainable.ENVIRONMENTAL CONSCIOUSNESS AND CUSTOMER ORIENTATION

The main global concerns at present are conservation of energy and pollution control. In future pressure will mount on the industry to reduce energy and GHG emissions. The energy consumption of many of the cement plants in India is comparable with the "best practices". However, there is still a scope to bring down the energy consumption by improving operational efficiency and plant technology. Though many plants have won environmental excellence awards but industry as a whole can still achieve better results on this front.The future initiatives have to be directed for using hazardous or waste materials (pet coke, used tyres, municipal and agricultural waste etc.) as fuel and larger use of fly ash, ggbs and other industrial waster like Zinc-lead slag, copper slag, steel slag etc. Both these ventures would contribute to environmental improvement and legislative and statutory authorities should support these initiatives.The customers have to be educated in proper use of cement and to avoid wastages at site. The inhibition to use mineral admixtures like fly ash, ggbs and blended cements should be removed through proper training and demonstrations at construction sites. The new code on concrete mix proportioning IS 10262 has been issued by BIS in 2009, rationalizing the use of binding materials and to avoid excessive use of cementing materials in concrete. The good construction practices should be encouraged by upgrading the skills of construction professionals for increasing the life of construction and to avoid the wasteful consumption of materials in repairs and rehabilitation. The mechanization in construction is another area which would need focus in future. The promotion of RMC during the last decade has brought numerous benefits in making concrete more reliable, durable and cost effective material. Similarly the pre-cast industry, which is in very nascent stage has potential to provide speed, quality and sustainability to construction projects. Promotion of these technologies and practices would provide additional impetus to the growth of cement industry in the coming decade.TOUGH TIMES CALL FOR TOUGH MEASURESThe industry has to overcome new challenges to be vibrant and healthy in future. The major hurdles are likely to be availability of quality raw materials at reasonable cost, energy sources, compatible infrastructure for movement of raw materials and finished goods, skilled man power and commensurate financial resources for continued technological up-gradations and innovations to meet the future aspirations of the construction industry and the society at large. These challenges can be met by combined efforts of industry friendly legislative frame work, boost of infrastructure by government, adoption of technologies to increase demand for cement and the cement industry by continuously striving for technological excellence and innovations in all fields of its operation. The Indian cement industry will emerge stronger, more efficient, sustainable and vibrant in future by virtue of its dedication and an intense urge to serve the construction industry in best possible manner.A.K.

Balancing Rapid Economic Growth and Climate Action

Published

Dr Yogendra Kanitkar, VP R&D, and Dr Shirish Kumar Sharma, Assistant Manager R&D, Pi Green Innovations, look at India’s cement industry as it stands at the crossroads of infrastructure expansion and urgent decarbonisation.

The cement industry plays an indispensable role in India’s infrastructure development and economic growth. As the world’s second-largest cement producer after China, India accounts for more than 8 per cent of global cement production, with an output of around 418 million tonnes in 2023–24. It contributes roughly 11 per cent to the input costs of the construction sector, sustains over one million direct jobs, and generates an estimated 20,000 additional downstream jobs for every million tonnes produced. This scale makes cement a critical backbone of the nation’s development. Yet, this vitality comes with a steep environmental price, as cement production contributes nearly 7 per cent of India’s total carbon dioxide (CO2) emissions.
On a global scale, the sector accounts for 8 per cent of anthropogenic CO2 emissions, a figure that underscores the urgency of balancing rapid growth with climate responsibility. A unique challenge lies in the dual nature of cement-related emissions: about 60 per cent stem from calcination of limestone in kilns, while the remaining 40 per cent arise from the combustion of fossil fuels to generate the extreme heat of 1,450°C required for clinker production (TERI 2023; GCCA).
This dilemma is compounded by India’s relatively low per capita consumption of cement at about 300kg per year, compared to the global average of 540kg. The data reveals substantial growth potential as India continues to urbanise and industrialise, yet this projected rise in consumption will inevitably add to greenhouse gas emissions unless urgent measures are taken. The sector is also uniquely constrained by being a high-volume, low-margin business with high capital intensity, leaving limited room to absorb additional costs for decarbonisation technologies.
India has nonetheless made notable progress in improving the carbon efficiency of its cement industry. Between 1996 and 2010, the sector reduced its emissions intensity from 1.12 tonnes of CO2 per ton of cement to 0.719 tonnes—making it one of the most energy-efficient globally. Today, Indian cement plants reach thermal efficiency levels of around 725 kcal/kg of clinker and electrical consumption near 75 kWh per tonne of cement, broadly in line with best global practice (World Cement 2025). However, absolute emissions continue to rise with increasing demand, with the sector emitting around 177 MtCO2 in 2023, about 6 per cent of India’s total fossil fuel and industrial emissions. Without decisive interventions, projections suggest that cement manufacturing emissions in India could rise by 250–500 per cent by mid-century, depending on demand growth (Statista; CEEW).
Recognising this threat, the Government of India has brought the sector under compliance obligations of the Carbon Credit Trading Scheme (CCTS). Cement is one of the designated obligated entities, tasked with meeting aggressive reduction targets over the next two financial years, effectively binding companies to measurable progress toward decarbonisation and creating compliance-driven demand for carbon reduction and trading credits (NITI 2025).
The industry has responded by deploying incremental decarbonisation measures focused on energy efficiency, alternative fuels, and material substitutions. Process optimisation using AI-driven controls and waste heat recovery systems has made many plants among the most efficient worldwide, typically reducing fuel use by 3–8 per cent and cutting emissions by up to 9 per cent. Trials are exploring kiln firing with greener fuels such as hydrogen and natural gas. Limited blends of hydrogen up to 20 per cent are technically feasible, though economics remain unfavourable at present.
Efforts to electrify kilns are gaining international attention. For instance, proprietary technologies have demonstrated the potential of electrified kilns that can reach 1,700°C using renewable electricity, a transformative technology still at the pilot stage. Meanwhile, given that cement manufacturing is also a highly power-intensive industry, several firms are shifting electric grinding operations to renewable energy.
Material substitution represents another key decarbonisation pathway. Blended cements using industrial by-products like fly ash and ground granulated blast furnace slag (GGBS) can significantly reduce the clinker factor, which currently constitutes about 65 per cent in India. GGBS can replace up to 85 per cent of clinker in specific cement grades, though its future availability may fall as steel plants decarbonise and reduce slag generation. Fly ash from coal-fired power stations remains widely used as a low-carbon substitute, but its supply too will shrink as India expands renewable power. Alternative fuels—ranging from biomass to solid waste—further allow reductions in fossil energy dependency, abating up to 24 per cent of emissions according to pilot projects (TERI; CEEW).
Beyond these, Carbon Capture, Utilisation, and Storage (CCUS) technologies are emerging as a critical lever for achieving deep emission cuts, particularly since process emissions are chemically unavoidable. Post-combustion amine scrubbing using solvents like monoethanolamine (MEA) remains the most mature option, with capture efficiencies between 90–99 per cent demonstrated at pilot scale. However, drawbacks include energy penalties that require 15–30 per cent of plant output for solvent regeneration, as well as costs for retrofitting and long-term corrosion management (Heidelberg Materials 2025). Oxyfuel combustion has been tested internationally, producing concentrated CO2-laden flue gas, though the high cost of pure oxygen production impedes deployment in India.
Calcium looping offers another promising pathway, where calcium oxide sorbents absorb CO2 and can be regenerated, but challenges of sorbent degradation and high calcination energy requirements remain barriers (DNV 2024). Experimental approaches like membrane separation and mineral carbonation are advancing in India, with startups piloting systems to mineralise flue gas streams at captive power plants. Besides point-source capture, innovations such as CO2 curing of concrete blocks already show promise, enhancing strength and reducing lifecycle emissions.
Despite progress, several systemic obstacles hinder the mass deployment of CCUS in India’s cement industry. Technology readiness remains a fundamental issue: apart from MEA-based capture, most technologies are not commercially mature in high-volume cement plants. Furthermore, CCUS is costly. Studies by CEEW estimate that achieving net-zero cement in India would require around US$ 334 billion in capital investments and US$ 3 billion annually in operating costs by 2050, potentially raising cement prices between 19–107 per cent. This is particularly problematic for an industry where companies frequently operate at capacity utilisations of only 65–70 per cent and remain locked in fierce price competition (SOIC; CEEW).
Building out transport and storage infrastructure compounds the difficulty, since many cement plants lie far from suitable geological CO2 storage sites. Moreover, retrofitting capture plants onto operational cement production lines adds technical integration struggles, as capture systems must function reliably under the high-particulate and high-temperature environment of cement kilns.
Overcoming these hurdles requires a multi-pronged approach rooted in policy, finance, and global cooperation. Policy support is vital to bridge the cost gap through instruments like production-linked incentives, preferential green cement procurement, tax credits, and carbon pricing mechanisms. Strategic planning to develop shared CO2 transport and storage infrastructure, ideally in industrial clusters, would significantly lower costs and risks. International coordination can also accelerate adoption.
The Global Cement and Concrete Association’s net-zero roadmap provides a collaborative template, while North–South technology transfer offers developing countries access to proven technologies. Financing mechanisms such as blended finance, green bonds tailored for cement decarbonisation and multilateral risk guarantees will reduce capital barriers.
An integrated value-chain approach will be critical. Coordinated development of industrial clusters allows multiple emitters—cement, steel, and chemicals—to share common CO2 infrastructure, enabling economies of scale and lowering unit capture costs. Public–private partnerships can further pool resources to build this ecosystem. Ultimately, decarbonisation is neither optional nor niche for Indian cement. It is an imperative driven by India’s growth trajectory, environmental sustainability commitments, and changing global markets where carbon intensity will define trade competitiveness.
With compliance obligations already mandated under CCTS, the cement industry must accelerate decarbonisation rapidly over the next two years to meet binding reduction targets. The challenge is to balance industrial development with ambitious climate goals, securing both economic resilience and ecological sustainability. The pathway forward depends on decisive governmental support, cross-sectoral innovation, global solidarity, and forward-looking corporate action. The industry’s future lies in reframing decarbonisation not as a burden but as an investment in competitiveness, climate alignment and social responsibility.

Carbon Capture Systems

Published

Nathan Ashcroft, Director, Strategic Growth, Business Development, and Low Carbon Solutions – Stantec, explores the challenges and strategic considerations for cement industry as it strides towards Net Zero goals.

The cement industry does not need a reminder that it is among the most carbon-intensive sectors in the world. Roughly 7–8 per cent of global carbon dioxide (CO2) emissions are tied to cement production. And unlike many other heavy industries, a large share of these emissions come not from fuel but from the process itself: the calcination of limestone. Efficiency gains, fuel switching, and renewable energy integration can reduce part of the footprint. But they cannot eliminate process emissions.
This is why carbon capture and storage (CCS) has become central to every serious discussion
about cement’s pathway to Net Zero. The industry already understands and accepts this challenge.
The debate is no longer whether CCS will be required—it is about how fast, affordable, and seamlessly it can be integrated into facilities that were never designed for it.

In many ways, CCS represents the ‘last mile’of cement decarbonisation. Once the sector achieves effective capture at scale, the most difficult part of its emissions profile will have been addressed. But getting there requires navigating a complex mix of technical, operational, financial and regulatory considerations.

A unique challenge for cement
Cement plants are built for durability and efficiency, not for future retrofits. Most were not designed with spare land for absorbers, ducting or compression units. Nor with the energy integration needs of capture systems in mind. Retrofitting CCS into these existing layouts presents a series of non-trivial challenges.
Reliability also weighs heavily in the discussion. Cement production runs continuously, and any disruption has significant economic consequences. A CCS retrofit typically requires tie-ins to stacks and gas flows that can only be completed during planned shutdowns. Even once operational, the capture system must demonstrate high availability. Otherwise, producers may face the dual cost of capture downtime and exposure to carbon taxes or penalties, depending on jurisdiction.
Despite these hurdles, cement may actually be better positioned than some other sectors. Flue gas from cement kilns typically has higher CO2 concentrations than gas-fired power plants, which improves capture efficiency. Plants also generate significant waste heat, which can be harnessed to offset the energy requirements of capture units. These advantages give the industry reason to be optimistic, provided integration strategies are carefully planned.

From acceptance to implementation
The cement sector has already acknowledged the inevitability of CCS. The next step is to turn acceptance into a roadmap for action. This involves a shift from general alignment around ‘the need’ toward project-level decisions about technology, layout, partnerships and financing.
The critical questions are no longer about chemistry or capture efficiency. They are about the following:

  • Space and footprint: Where can capture units be located? And how can ducting be routed in crowded plants?
  • Energy balance: How can capture loads be integrated without eroding plant efficiency?
  • Downtime and risk: How will retrofits be staged to avoid prolonged shutdowns?
  • Financing and incentives: How will capital-intensive projects be funded in a sector with
    tight margins?
  • Policy certainty: Will governments provide the clarity and support needed for long-term investment
  • Technology advancement: What are the latest developments?
  • All of these considerations are now shaping the global CCS conversation in cement.

Economics: The central barrier
No discussion of CCS in the cement industry is complete without addressing cost. Capture systems are capital-intensive, with absorbers, regenerators, compressors, and associated balance-of-plant representing a significant investment. Operational costs are dominated by energy consumption, which adds further pressure in competitive markets.
For many producers, the economics may seem prohibitive. But the financial landscape is changing rapidly. Carbon pricing is becoming more widespread and will surely only increase in the future. This makes ‘doing nothing’ an increasingly expensive option. Government incentives—ranging from investment tax credits in North America to direct funding in Europe—are accelerating project viability. Some producers are exploring CO2 utilisation, whether in building materials, synthetic fuels, or industrial applications, as a way to offset costs. This is an area we will see significantly more work in the future.
Perhaps most importantly, the cost of CCS itself is coming down. Advances in novel technologies, solvents, modular system design, and integration strategies are reducing both capital requirements
and operating expenditures. What was once prohibitively expensive is now moving into the range of strategic possibility.
The regulatory and social dimension
CCS is not just a technical or financial challenge. It is also a regulatory and social one. Permitting requirements for capture units, pipelines, and storage sites are complex and vary by jurisdiction. Long-term monitoring obligations also add additional layers of responsibility.
Public trust also matters. Communities near storage sites or pipelines must be confident in the safety and environmental integrity of the system. The cement industry has the advantage of being widely recognised as a provider of essential infrastructure. If producers take a proactive role in transparent engagement and communication, they can help build public acceptance for CCS
more broadly.

Why now is different
The cement industry has seen waves of technology enthusiasm before. Some have matured, while others have faded. What makes CCS different today? The convergence of three forces:
1. Policy pressure: Net Zero commitments and tightening regulations are making CCS less of an option and more of an imperative.
2. Technology maturity: First-generation projects in power and chemicals have provided valuable lessons, reducing risks for new entrants.
3. Cost trajectory: Capture units are becoming smaller, smarter, and more affordable, while infrastructure investment is beginning to scale.
This convergence means CCS is shifting from concept to execution. Globally, projects are moving from pilot to commercial scale, and cement is poised to be among the beneficiaries of this momentum.

A global perspective
Our teams at Stantec recently completed a global scan of CCS technologies, and the findings are encouraging. Across solvents, membranes, and
hybrid systems, innovation pipelines are robust. Modular systems with reduced footprints are
emerging, specifically designed to make retrofits more practical.
Equally important, CCS hubs—where multiple emitters can share transport and storage infrastructure—are beginning to take shape in key regions. These hubs reduce costs, de-risk storage, and provide cement producers with practical pathways to integration.

The path forward
The cement industry has already accepted the challenge of carbon capture. What remains is charting a clear path to implementation. The barriers—space, cost, downtime, policy—are real. But they are not insurmountable. With costs trending downward, technology footprints shrinking, and policy support expanding, CCS is no longer a distant aspiration.
For cement producers, the decision is increasingly about timing and positioning. Those who move early can potentially secure advantages in incentives, stakeholder confidence, and long-term competitiveness. Those who delay may face higher costs and tighter compliance pressures.
Ultimately, the message is clear: CCS is coming to cement. The question is not if but how soon. And once it is integrated, the industry’s biggest challenge—process emissions—will finally have a solution.
