Cement companies put up capacities in excess of demand in anticipation of increased consumption of cement on account of expected hike in government spending, which did not materialize. N. A. Viswanathan, Secretary General, Cement Manufacturers’ Association dwells on the issues dogging the cement industry and spells out what needs to be done by the government to tackle these issues.Cement industry, which has a direct co-relation of 1.1 to 1.2 with GDP, plays a pivotal role in the infrastructure development of the country. Buoyed with various infrastructure policies and schemes of the government, particularly after 1982 (partial decontrol) of cement, this industry had added substantial cement capacities year-after-year, much ahead of the actual cement demand taking place. However, the overall slowdown in the economy at 6.5 per cent in FY12, which further contracted to 5.3 per cent in the Apr-Jun quarter of 2012, one of the lowest in nine years, resulting in dampening construction activities, weakening of the rupee value against dollar and higher interest rates of borrowings, to quote a few, have made a severe dent on the growth of the cement industry, from an average growth of around 10 per cent in the last couple of years to a low growth of 5 per cent in FY11 and 6.3 per cent in FY12 respectively. For no fault of theirs, the cement industry has recently been criticised and also harshly penalised for under-utilising the cement capacity, without appreciating the ground realities and the factors which have contributed to reduced capacity utilisation. Today, because of the huge mismatch between demand and supply of cement, the country is having about 93 million tonnes of excess cement capacity created after making colossal investments. To revive the economy from its present slackening mode, it is now imperative for the government to enh-a-nce cement demand by taking some positive and concrete policy measures.The backgroundThough the cement industry has been in existence since 1914, appreciable growth in the cement production has been witnessed only after the introduction of partial decontrol in 1982 culminating in total decontrol in 1989 and delicensing in 1991. With the implementation of liberalisation policies of the government in 1991 followed by government’s thrust on infrastructure development in the country, the pace of the growth of the cement industry has been unprecedented.Exponential GrowthThe burgeoning growth of the industry can be gauged from the fact that for creating the first 100 million tonnes capacity, prior to partial decontrol era, the industry took 83 long years, whereas to reach the second and third 100 million tonnes mark, the period had substantially shrunk to 11 years and less than 4 years, respectively (see chart). Cement capacity which was 64.55 million tonnes in 1990-91 reached 340.44 million tonnes in 2011-12. Similarly, cement production went up from 48.90 million tonnes to 247.32 million tonnes during the same period.World Class IndustryIndia is the second largest cement producing country in the world, next only to China both in quality and technology. It produces about 7 per cent of the global production. In 2010, world production of cement was 3294 million tonnes. It is a matter of concern that even after attaining the second position, our per capita cement consumption is very low at 180 kg., which is much below the global average of 450 kg. (see table).Per capita consumption of cement is accepted as an important index of the country’s economic growth. Hence, there is enough potential to enhance our per capita cement consumption to match with the world average.With the adoption of massive modernisation and assimilation of state-of-the-art technology, Indian cement plants are today most energy-efficient and environment-friendly and are comparable to the best in the world in all respects, whether it is kiln size, technology, energy consumption or environment-friendliness. Industry has progressively reduced its energy consumption from 800-900 kwh/tonne clinker in 80s to 650-750 kwh/tonne clinker now. Similarly, power consumption registered a remarkable improvement from 105-115 kwh/tonne cement to 70-90 kwh/tonne cement during the said period. Presently, about 99 per cent of the total capacity in the industry is based on modern and environment-friendly dry process technology. Cement industry has now been making sincere efforts to utilise waste heat recovery in the plants.Problems plaguing the industryThere are a number of constraints and bottlenecks which are hindering the growth of this core sector industry. A few of the major concerns of the industry are discussed below:Excess cement capacity: Cement industry has been experiencing glut situation as there has been mammoth mismatch between cement demand and its supply. The industry had created the capacity on the back of government’s projection of potential cement demand arising out of the thrust given for infrastructure development in the country and the allocation of funds earmarked for the purpose. However, the cement demand, as projected, has not materialised, despite the capacity having been created well in advance after making huge investments.Acute shortage of coal: Coal is one of the major raw materials needed by the industry both in the manufacturing of cement and also for generating power. In the last couple of years, there has been a steep drop in the supply of linked coal to the cement industry from 70 per cent in FY04 to almost 39 per cent now, mainly due to diversion of coal to the power sector. Cement companies, therefore, have perforce to resort to either open market purchase or imported coal which works out to nearly 2 to 2.5 times higher than the domestic price or use of the alternate fuel like pet coke, lignite, etc. which also adds up significantly to the additional cost of production. What is worse, new capacities are not being given any coal under the Linkage Scheme and therefore there is a real fear that the shortage of the main fuel, with no assurance of its availability in future, may actually hamper the required capacity additions for future build up. With the increasing cost of coal and other input materials such as diesel, etc. the production cost of cement has gone up significantly.Inadequate availability of wagons: Rail is the ideal mode of transportation for cement industry. However, it has always been plagued by the short supply of wagons, particularly during the peak period. In addition to this, infrastructure constraints and also not factoring the points of view of the cement industry, which is one of its largest consumers, in the policies of the railways have been hampering the planned movement of cement to the consumption centres, adversely impacting the production schedule and also increasing the overall transportation cost of cement. Rail share for cement which was 53 per cent a couple of years back has come down to 35 per cent now, which is a matter of great concern both to the cement industry and the railways.Cement highly taxed: Although cement is a high volume low value product, it is one of the highly taxed commodities (60 per cent of the ex-factory price), even more than luxury goods. This is exclusive of the freight transportation, which is about 20 per cent of the operating cost. The levies and taxes on cement in India are far higher compared to those in the countries of Asia-Pacific region or even compared to the developing economies like Pakistan and Sri Lanka. Cement and steel are two major materials needed for construction of any infrastructure. However, it is ironic that the rate of VAT charged on cement and steel differs vastly. While the value-added tax (VAT) on steel is only four per cent, it is 12.5 per cent on cement/clinker which goes up to even 15 per cent in some of the states.Steep fall in cement exports: With the high incidence of government levies, infrastructure constraints at ports and the regulatory policies of the government providing encouragement for import of cement with nil custom duty, the export of cement and clinker from India has been steadily and continuously declining from 9 million tonnes in FY07 to 3.5 million tonnes in FY12, despite the fact that Indian cement industry is presently having the substantial excess capacity of cement and clinker.Use of fly ash unviable: Cement industry’s initiative and investment to the tune of more than Rs 1000 crore for effectively utilizing the industrial waste fly ash, which was otherwise posing a nuisance as a health hazard, has helped the thermal power plants in addressing and tackling the menace of fly ash related health and environmental hazards. However, power plants which had been earlier supplying fly ash to the cement industry free of cost have for the last couple of years, as per the order of the Ministry of Environment and Forests, started charging for fly ash from November 2009. The order has also made it mandatory for the cement plants having captive power plants to supply 20 per cent of the fly ash generated as free of cost to the small scale brick manufacturers, etc. within the vicinity of 100 kms of their plants. Both these have severely impacted the production cost of cement and also seriously threatened the fly ash recycling potential in the country.XII Plan – cement demand projectionsAs per the report submitted to the Planning Commission recently by the Working Group on Cement Industry for XIIth Plan, the country’s cement production and capacity is estimated to surge from 247.32 million tonnes and 340.44 million tonnes respectively in FY12 to 407.4 million tonnes and 479.3 million tonnes respectively by FY17.Future OutlookThe slackening economy will take at least one or two years to bounce back to its earlier level. This would, as a thumb rule, apply to the cement industry also. Since India has been emerging as one of the fastest growing economies in the world, the future outlook for cement looks to be bright, provided government formulates facilitating growth oriented policies so that our per capita cement consumption matches with at least with some of the developing economies.Measures for stimulating cement demandIt is imperative to bring back this core cement industry on higher and faster growth trajectory by revival of cement demand through faster growth of infrastructure sector, including roads, ports, airports, housing, irrigation projects, and so on. This would be possible particularly by bringing out more encouraging schemes for affordable housing with income tax relief and by constructing long-lasting cement concrete roads and adopting cement concrete canal lining to conserve 50 per cent precious water that presently seeps through our unlined canals. Water thus saved can be effectively utilized for our agriculture and other needs. The government’s long cherished ‘dream’ to provide ‘world-class standard roads’ can be fulfilled only if cement concrete roads and white topping (a technology on which a concrete layer is laid on the existing bitumen road) are adopted in the country on a larger scale. It is a well-established fact that cement concrete roads are long-lasting, maintenance-free for 30-40 years and today, in most of the cases, are even economical than bitumen roads in the construction stage itself and are, therefore, much-needed for the exponential growth of our economy. Further, cement roads can simultaneously resolve, without entailing any extra financial cost, a number of national issues and problems the government is grappling to find solutions even after spending thousands of crores of rupees every year. The problems which would be addressed are – (a) conservation of diesel and petrol up to 14 per cent as heavy load carriers consume less fuel on concrete roads than while plying on bitumen roads (b) preservation of precious foreign exchange being spent on the import of bitumen used in the construction of roads (c) utilization of fly ash up to 35 per cent, disposal of which is a nuisance and health hazard (d) conservation of 10 per cent electricity used for the street lights (e) protection of our quarries and mines and above all (f) generation of substantial downstream employment.Coal supply and wagon availability to the cement industry, which have become very acute and uncertain in the recent past, needs to be assured on a consistent and regular basis to the cement industry to facilitate it to meet the projected cement demand of the country.Further, the government needs to initiate certain measures in the form of providing tax incentive to the industry, reduce the overall tax value on the commodity and phase out cross subsidy on electricity, diesel and railway freight in a gradual manner. The government can also consider classifying cement as "Declared Goods" like steel having a uniform VAT rate of 4 per cent throughout the country. The overall taxation value on cement can be brought down to a level of 20-25 per cent of ex-works selling price from the current level.Tax incentive should also be pro-vided by the government for pro-moting blended cement in the larger interest of mineral conservation, waste utilization and bringing down carbon emission.Above all, level playing field needs to be provided to the domestic manufacturers to encourage cement and clinker exports by re-imposing custom duty on cement, which is nil at present. Additionally, Ready Mix Concrete (RMC) needs to be encouraged leading to bulk supply of cement and consequent reduction in pack-aging cost.It is a matter of record that even during the worst phase of economic slow-down, the Indian cement industry has surprised the economy watchers by its pace of sustained growth bucking the general trend of negative or slow growth of economy and the industry sector. It is, therefore, not too optimistic to presume that if the suggested measures are implemented, the cement industry will not only become a leader amongst the various sectors of the industry but will also emerge as a showpiece of model infrastructural growth contributing, in turn, to economic growth.

Dr SB Hegde analyses the changing trend in the cement industry as it faces a growing skill gap as ageing workers retire and new talent turns away, threatening efficiency and sustainability.
Cement is the backbone of roads, buildings and cities worldwide. In 2023, the world produced 4.1 billion tonnes of cement, and that number could grow to 4.7 billion tonnes by 2030 (US Geological Survey, 2024). However, there’s a big problem — the cement workforce is ageing and not enough young workers have the skills to operate modern machines or meet new environmental standards. This skill gap — the difference between what the industry needs and what workers can do — is growing quickly. It’s a hidden threat that could slow down construction projects and
hurt economies.
Cement drives development worldwide, but countries like India are feeling the pressure the most. In 2022, India produced 410 million tonnes of cement, making it the second-largest producer after China (Statista, 2024a). With major infrastructure plans for roads and railways, India needs skilled workers more than ever. However, many cement plants are struggling to find workers who understand modern tools or environmentally friendly methods.
This article explores why this skill gap exists, how it impacts the industry, and what can be done to fix it—both globally and in India. With updated statistics and real-world examples, it sends a clear message: cement companies must take action before the problem gets worse.
The hidden crisis
The skill gap in the cement industry is a growing problem that’s not always easy to see. Across the world, experienced workers who have spent decades mastering cement production are retiring. A 2023 report shows that 30 per cent of them are over 50, and new workers aren’t stepping in fast enough, especially in Europe and the US (World Cement Association, 2024).
At the same time, cement plants are becoming more advanced, using technology like smart sensors, automated systems and robots. These systems require workers with technical and computer skills—not just physical strength and basic knowledge.
India is also feeling the heat. With the capacity to produce 690 million tonnes of cement yearly, the industry employs over 1 million people (IBEF, 2024). But according to a 2024 study, 65 per cent of plant managers report not having enough skilled workers to handle modern machinery (CII, 2024). This problem is even worse in southern India, where too many plants compete for limited talent, and low wages push skilled workers to better-paying city jobs.
This skill shortage affects the industry in several ways:
- Higher maintenance costs: Without skilled workers, machines break down more often.
- Reduced cement quality: Poorly operated machinery affects the consistency and quality of cement.
- Increased production costs: Inefficiencies lead to higher operational costs.
The crisis is reshaping how cement is made and forcing companies to rethink their strategies. If the industry doesn’t tackle this problem soon, it could face severe setbacks in productivity, quality and profitability.
From skill to crisis
Cement production used to rely heavily on hands-on skills. Workers learned through experience—breaking rocks, firing kilns and mixing materials. But today, machines handle most of that work. Around 80 per cent of the world’s cement now comes from dry processes, which require less labour but more technical expertise (Rhodium Group, 2024).
The older generation of workers, who mastered traditional methods, often struggle to adapt to modern systems. Meanwhile, younger workers are not being trained quickly enough to fill the gap. This shift is making the industry less efficient and more vulnerable.
India is a prime example of this transformation. Small cement plants once thrived on local skills and traditional methods. But now, large companies like UltraTech, which produces 79 million tonnes of cement annually, are using advanced technologies like waste heat recovery systems (WHRS) to save energy and reduce emissions (IBEF, 2024).
However, a 2023 survey by the National Skill Development Corporation (NSDC) revealed that only 20 per cent of cement workers in India are capable of handling these modern systems (NSDC, 2024). This lack of expertise leads to several problems:
- Inefficiencies in production: Poorly operated technology slows down manufacturing.
- Reduced sustainability efforts: Without skilled workers, eco-friendly systems like WHRS are not fully effective.
- Higher operating costs: More downtime and maintenance result from improper handling of equipment.
The old craftsmanship is fading, leaving the industry at a crossroads. Without immediate action, this skill shortage could severely impact cement production’s ability to meet growing demands and adopt sustainable practices.
Technology’s double-edged sword
Technology is both a solution and a challenge for the cement industry. Around the world, new tech is making cement production faster, cleaner and more efficient. For example, Cemex tested solar-powered cement in 2023, aiming for eco-friendly production, while Heidelberg invested €450 million in carbon capture technology in Belgium (World Cement Association, 2024). These innovations are part of why the global cement market could reach $686 billion by 2032 (Fortune Business Insights, 2025).
However, the catch is that these high-tech solutions require skilled workers who understand how to operate and maintain advanced systems—not just traditional manual labour.
India is also riding the wave of automation. Cement plants are now getting 20–25 per cent of their power from WHRS, which save energy and reduce costs (World Cement, 2025). When Adani acquired Sanghi Industries for $606.5 million in 2023, it added more advanced technology to its operations. But the problem remains: local workers often lack the skills needed to handle this new machinery effectively.
While technological advancements have helped India produce 375 million tonnes of cement in 2023, they are also creating a divide within the workforce. The industry is splitting into two groups:
- Tech-savvy workers: A small group trained to handle automation, digital systems and advanced equipment.
- Traditional workers: A much larger group lacking the skills needed to work with modern technology.
This divide leads to several challenges:
- Underutilised technology: Many high-tech systems are not fully used due to a lack of trained operators.
- Increased operational costs: Companies spend more on training and maintenance when technology is poorly managed.
- Job insecurity: As automation grows, workers with outdated skills face the risk of being left behind.
The cement industry must find a balance between adopting new technologies and ensuring workers have the skills to operate them effectively. Without doing so, the push for efficiency and sustainability could leave a large part of the workforce struggling to keep up.
Why is the young talent avoiding the cement industry?
Young people are not interested in working in the cement industry. Globally, only about 5 per cent of engineering graduates from the US and Europe consider manufacturing jobs, according to a 2023 report (McKinsey, 2023). They see cement jobs as dirty, boring and outdated compared to high-paying tech jobs with modern offices and exciting projects.
India faces the same problem. Although the cement industry contributes around 6 per cent to the country’s economy, it struggles to attract fresh talent. In 2023, the IT sector hired 1.5 million graduates, while the cement industry managed to recruit only about 50,000 (NSDC, 2024). Cities like Bengaluru, known for their booming tech hubs, lure young engineers who prefer coding jobs over working in hot, dusty cement plants in places like Rajasthan.
The perception problem is real. A 2024 survey revealed that 70 per cent of Indian engineering students described cement work as ‘dull’ and ‘unappealing,’ even though starting salaries can be quite competitive, ranging from `8 to Rs.12 lakh per year (CII, 2024). They don’t see cement as a modern, innovative field with growth opportunities.
Beyond the factory floor
The skill shortage in the cement industry isn’t just a factory problem—it’s a major issue for big construction projects worldwide. When cement plants struggle to find skilled workers, everything slows down, causing costly delays.
In the US, the $1.2 trillion infrastructure plan aimed at upgrading roads, bridges and railways is already feeling the pressure. Cement shortages caused by untrained workers are holding back progress (Fortune Business Insights, 2025).
Africa faces a similar problem. Cement demand on the continent is expected to grow by 77 per cent by 2030. But without skilled workers, meeting that demand will be nearly impossible, stalling economic growth and infrastructure development (World Cement Association, 2024).
India is feeling the pinch more than most. The country’s $14.59 billion infrastructure plan, which includes building highways, smart cities and bullet train projects, heavily relies on cement (IBEF, 2024). One of the most ambitious projects, the Mumbai-Ahmedabad Bullet Train, requires a staggering 20,000 cubic metres of cement daily. But skill shortages are disrupting supply, leading to delays.
The problem isn’t just limited to mega-projects. For example, Chennai’s metro expansion faced major delays in 2023 because local cement plants couldn’t meet demand on time. The skill gap is directly impacting the speed and quality of these projects.
What’s at risk?
- Job creation: India’s construction boom is expected to create around 1 million jobs, but if the cement industry can’t keep up, those opportunities will be lost.
- Economic growth: Infrastructure development contributes significantly to GDP. Delays in cement supply can slow down the entire economy.
- Global competitiveness: If India and other countries can’t resolve this skill gap, their ability to compete on a global scale will be compromised.
Bridging the gap
The skill gap in the cement industry isn’t impossible to fix—new training models worldwide are making a difference. Countries and companies are trying out fresh ideas to build a skilled workforce.
In Germany, a dual education system that combines classroom learning with hands-on factory training is producing 60,000 skilled workers every year (IEA, 2023). It’s a practical approach where students gain real-world experience while studying, making them job-ready from day one.
Companies are also stepping up. Holcim introduced virtual reality (VR) training in 2024, allowing workers to practice operating complex cement plants in a simulated environment. This approach saves time, money, and reduces accidents during training.
India is making efforts too. UltraTech’s skill centres trained 10,000 workers in 2023, focusing on areas like automation, machine handling, and safety (IBEF, 2024). The company is trying to bridge the skill gap by equipping workers with modern technical skills.
Collaborations are also happening. Shree Cement has partnered with IIT Kharagpur, producing 500 skilled engineers annually since 2022. This initiative aims to bring fresh talent into the industry, particularly in high-tech areas.
The National Skill Development Corporation (NSDC) and Ambuja Cement have even bigger plans. They aim to train 50,000 young people by 2029, with a special focus on green technologies and sustainable manufacturing.
Why this matters:
- Reducing the skill gap: If these training programmes expand successfully, India’s 65 per cent skill shortage could be significantly reduced by 2030.
- Improving productivity: Better-trained workers mean fewer machine breakdowns, improved cement quality and reduced costs.
- Boosting economic growth: Skilled workers are essential for completing big infrastructure projects on time, directly supporting economic development.
Sustainability at risk
Achieving sustainability in cement production isn’t just about technology—it’s about having skilled workers who can operate and maintain green systems. The cement industry is responsible for 6–8 per cent of the world’s CO2 emissions, pushing companies to find eco-friendly solutions (IEA, 2023).
In 2024, a plant in the UK managed to cut its emissions by 85 per cent by adopting advanced technologies. But here’s the catch: running these systems needs highly trained workers who understand how to use and maintain them.
India is also striving for greener cement production. Major companies like JK Cement have set ambitious targets, aiming to use 50 per cent biomass fuel by 2030. However, only 15 per cent of the workforce currently has the necessary skills to handle this transition effectively (CII, 2024).
Ambuja Cement’s Concrete Futures Lab is one initiative trying to close the skill gap by training 2,000 workers each year in eco-friendly cement production. But compared to the scale of the industry, that’s not nearly enough.
Why this matters:
- Carbon-neutral goals at risk: India’s target of achieving carbon-neutral cement production by 2050 is in danger if the workforce isn’t adequately skilled.
- Need for better training programmes: Without widespread and advanced training programmes, green technologies will remain underutilised, slowing down the progress toward sustainability.
- Global impact: What’s true for India is true for the world—if we don’t bridge the skill gap, the dream of reducing cement’s carbon footprint may stay out of reach.
- The solution is clear: We need more training centres, better courses, and partnerships between companies, educational institutions, and the government to make green cement production a reality.
The global skill gap
The skill gap in cement manufacturing is a worldwide problem, but it looks different depending on where you are.
In the US, which produced 91 million tonnes of cement in 2023, the main issue is a shortage of workers with digital skills to operate advanced systems (World Cement, 2025).
In Africa, the problem is more basic. The industry lacks trained workers altogether, which could severely impact its cement demand expected to rise by 77 per cent by 2030 (World Cement Association, 2024).
India faces a mixed challenge. Northern cement plants struggle to find workers with the technical expertise to handle modern, automated systems. In contrast, southern plants have a surplus of workers, but their skills are outdated or irrelevant. NSDC trains around 50,000 workers annually, but that’s far too little compared to the rapidly growing demand (World Cement, 2025).
In China, the government takes a proactive approach, training 200,000 workers each year through organised programmes to support its massive production of 2.1 billion tonnes in 2022 (Statista, 2024b).
Why this matters:
- India’s demand boom: Cement demand in India is projected to increase by 42 per cent by 2030, but without the right skills, meeting that demand will be difficult.
- Learning from others: Countries need to collaborate, sharing training models and technologies to address skill shortages effectively.
- Bridging the gap: Without the right skillsets, the cement industry’s growth and sustainability goals are at serious risk worldwide.
The urgent need to address the skill shortage
Time is running out. By 2024, the world will have a surplus of 1 billion tonnes of cement, but only skilled workers can make sure it’s used properly (World Cement Association, 2024). In India, the demand for cement could grow by 7–8 per cent every year through 2027, needing $14.89 billion in new plants (CRISIL, 2024). But without the right skills, this growth is at risk.
Here’s the hard truth for cement companies: current efforts aren’t enough. Training 10,000 workers, like UltraTech did, is a good start, but India needs 500,000 more skilled workers by 2030 to keep up with demand. Globally, companies are hoarding technology but aren’t sharing the necessary training, leaving developing regions behind. In India, companies often focus more on profits than on developing talent. Southern plants, for example, lower wages instead of investing in training, causing skilled workers to leave for better-paying jobs in IT. As for sustainability? Many green projects are just for show unless workers have the skills to run them.
So, what’s the solution? Companies need to think bigger. Globally, the cement industry should pool resources and create an industry fund for training, like the oil industry does for research and development. They should share training tools, like virtual reality, to help regions like Africa catch up. In India, companies like UltraTech and Adani should take the lead by partnering with all engineering colleges—not just the top ones—and offering scholarships to attract young talent. Rural plants should raise wages to compete with city jobs. Governments can help too, like India’s 2025 budget could offer tax cuts to companies that train workers, similar to Germany’s model.
But here’s the tough reality: many cement companies resist change. They prefer to squeeze more out of their current workforce rather than investing in new talent. That approach won’t work. If they don’t act now—really act—plants will shut down, projects will be delayed, and sustainability goals will fail. The choice is clear: build a skilled future or watch everything collapse. Which path will you take?
Conclusion
The skill shortage in cement manufacturing is a serious issue, both globally and in India, and it can’t be ignored any longer. As older workers retire, technology is taking over, but young people aren’t interested in cement jobs. This is causing growth to slow down and impacting green initiatives worldwide. In India, with its massive cement production of 410 million tonnes a year and big plans for the future, the situation is even more critical—65 per cent of plants lack skilled workers, putting jobs and infrastructure at risk.
However, there’s hope. New training programmes, like UltraTech’s centres or global VR training tools, show progress, but these efforts aren’t enough yet. Companies must act quickly, share ideas and invest more in training their workforce. If India makes the right moves, it could boost its production to 599.7 million tonnes by 2032 (IMARC Group, 2024). The global cement industry can also thrive with the right investment in skills.
Ignoring the skill gap means risking the foundation of the cement industry—and the future of construction worldwide. Cement companies must decide now: invest in skilled workers and grow, or let the industry’s progress crumble.

Alternative fuels reduce cement plants’ carbon footprint, but infrastructure challenges limit adoption. Technologies like the HOTDISC® Reactor help overcome these barriers.
Alternative fuels are a relatively straightforward and readily available means of reducing a cement plant’s carbon footprint. The technology is proven and well used worldwide, and with the right controls in place the switch from fossil fuels to waste-derived fuels does not impact the quality of the end product. In some countries, cement plants are achieving near 100 per cent substitution in the calciner and high levels of substitution in the kiln. However, this trend is not universal, and some countries are struggling to achieve a thermal substitution rate (TSR) of 25 per cent. In this article, we will look at the obstacles to alternative fuels use and the technology that is available to overcome them.
Advantages of alternative fuels
Alternative fuels offer three key environmental advantages.
1) A lower carbon alternative to coal or petcoke.
2) A pathway for waste that might otherwise be landfilled, including hazardous waste.
3) An alternative to waste incineration, which is typically done at lower temperatures where emissions tend to be higher.
In addition, the cost of alternative fuels can often be lower than fossil fuels and is not subject to the fluctuations of the energy market.
The sources of alternative fuels are many and varied – to the extent that the supply chain looks vastly different from one region to the next. For example, whereas India has abundant sources of biomass such as rice husk, in Western Europe there are plentiful supplies of refuse-derived fuel (RDF). This is partly a matter of industry and partly of infrastructure. But given the importance of reducing the cement industry’s reliance on coal, a lack of infrastructure must not prevent greater utilisation of alternative fuels – which is why FLSmidth Cement has for some time been developing alternative fuels solutions that reduce the burden of pre-processing and enable cement plants to more easily and more cost-effectively utilise a wide variety of waste streams.
A solution for all waste
Direct calciner injection may seem like the simplest way to replace fossil fuels with alternatives. However, it’s not always the best. The options for alternative fuels are limited by the necessity to pre-process fuel in preparation for burning, which, as stated, requires established infrastructure, or additional facilities at the plant.
Though the CAPEX cost of direct calciner injection is low, the calciner fuel substitution rate is also low, so this method doesn’t enable cement plants to optimise the potential for fuel replacement. Plant operators must also consider the impact on the process of direct injection, which doesn’t allow the long residence time that can be required to reduce process volatility. No plant wants to contend with greater instability or an increase in emissions from adding alternative fuels to the mix. Fortunately, direct calciner injection is not the only option. There are other ways of extracting energy from waste that require no pre-processing at all.
The HOTDISC® Reactor can handle a wide variety of solid waste in sizes up to 1.2m – from sludge or grains to whole truck tyres. There’s no need for expensive shredding or pre-drying, or any pre-processing, which removes one of the obstacles to adopting alternative fuels. The broad range of accepted fuel types also means cement plants are free to shop the market and not tied into one supplier. This makes it a very cost-effective solution because cement plants can select the lowest cost fuel without worrying about the quality.
How does the HOTDISC® work?
The HOTDISC® is a moving hearth furnace that is integrated into the pyroprocess below the calciner bottom and above the kiln riser. Coarse alternative fuels are fed onto a slowly rotating disc. Hot tertiary air is directed into the HOTDISC to provide an oxidising atmosphere for the alternative fuel to burn. As the alternative fuel slowly travels around approximately 270 degrees on the rotating disc, almost all of it fully combusts. Depending on the nature of the alternative fuel (size, heat content, moisture, etc.), the rotational speed of the HOTDISC can be adjusted to optimise the residence time (up to 45 minutes) and combustion rate. In addition, the temperature inside the HOTDISC is controlled by directing a portion of the preheated raw meal into the HOTDISC. The HOTDISC operation generates a controlled mix of hot gases, combustion residue (ash) and calcined raw meal that exits the HOTDISC. The combustion gases and finer materials are carried with the hot gases into the bottom of the calciner, while the coarser residues meet a scraper at the end of the 270 degrees rotation, where they are directed down into the riser duct. From there, this material falls into the kiln and is incorporated into the clinker.
The HOTDISC is designed to achieve a calciner substitution rate in the range of 50 to 80 per cent – or even higher – of the calciner fuel. Results vary by the specific plant conditions and fuel specification, but based on over 20 years of plant data it is possible to predict the substitution rate in each application.
The HOTDISC was originally designed for use with In-Line Calciners (ILCs), but new models are now available for use with Separate Line Calciners (SLCs), enabling the HOTDISC to be installed under the calciner and still deliver the same benefits. The HOTDISC-S is installed in the bottom part of the SLC calciner on the ground, the reject will be cooled and transported to a container or back into the system, gas flow and AF flow operates counter current.
For cement plants that wanted to utilise a wide range of alternative fuels, the HOTDISC®-S is a cost-saving solution that avoids the expense of changing the SLC to an ILC while enabling a high substitution of alternative fuels. Another model, the HOTDISC®-HMT (Hot Material Transport), enables quicker and easier installation of the HOTDISC in existing plants. Instead of directly integrating the exit of the HOTDISC reactor to the calciner and riser duct, the new layout allows the HOTDISC reactor to be mounted two to five metres away. It is then connected to the calciner and riser duct via a hot material transport chute for gas flows and combustion ashes.
Further advances in alternative fuels technologies
Low or varying quality alternative fuels can be another inhibitor to substitution, given the requirements of the relatively delicate cement pyro process. FLSmidth Cement has expended considerable R&D effort developing solutions that can accommodate a wide range of fuel types, knowing that this is the easiest path to greater substitution and ultimately the near-elimination of fossil fuels. The FUELFLEX® Pyrolyzer was one result of this effort and offers an exciting prospect for cement plants wishing to achieve near – 100 per cent substitution in the calciner and minimise NOx emissions.
The FUELFLEX® Pyrolyzer utilises hot meal from the lower preheater cyclones (yellow arrows) to dry and pyrolyze RDF or biomass. Either part or the full stream of hot meal from a lower preheater cyclone is admitted to the Pyrolyzer via the U-Lock (controlled by two dividing gates). The U-Lock fluidises the hot meal, forming a U-shaped gas lock that prevents pyrolysis gases from flowing backwards through the process. Subsequently the hot meal stream flows into the Pyrolyzer vessel, which also has a U-shaped lower aerated section to contain the hot fluidised meal. Fuel is pneumatically fed to the pyrolyzer vessel wherein through contact with the hot meal, it is dried, heated and pyrolyzed to form reactive gases and char. The gases push upwards into the main pyrolyzer vessels while the char falls down into the fluidised meal bed, before being reunited and fed as a very reactive stream into the calciner. Aeration panels are used to fluidise the hot meal and drain gates are used to drain out debris and meal from the pyrolyzer to the kiln system in a controlled manner. The reactive stream of pyrolysis products reacts with rotary kiln NO by so-called ‘re-burning’ reactions, utilising pyrolysis gases to convert NO into free N2 in the reduction zone prior to mixing with preheated combustion air in the calciner. In addition, the full fuel pyrolysis preceding the calciner helps limit calciner NOx formation by limiting access to oxygen when burning.
By using the FUELFLEX® Pyrolyzer, cement plants can achieve up to 100 per cent fossil fuel replacement in the calciner, with the following benefits:
- Reduced CO2 emissions, as net CO2 emissions from alternative fuels generally are lower than from fossil fuels.
- Increased utilisation of local waste streams, avoiding the need to dispose of or store this waste in other ways.
- Reduced fuel costs, especially in times of fluctuating energy prices.
- Reduced fossil fuel use saves the associated environmental impact of fossil fuel extraction and transport.
Conclusion
The challenge is on: cement plants must reduce carbon emissions now, and continue to do so for the next several decades until the target of net zero is met. While there are some solutions that are not ready yet – i.e. carbon capture – alternative fuels offer a valuable means of reducing the cement industry’s environmental impact immediately, with the added benefit of providing a controlled means of waste disposal. New and proven technologies will help the cement industry to overcome alternative fuel supply chain problems and achieve a dramatic reduction in fossil fuel use.
