This week we covered Capitol Aggregates’ order of an alternative fuels (AF) system from ATS Walter USA. The story is notable because it is an AF project for a cement plant in the US. Thermal substitution rates (TSR) of AF in the US have typically been lower than in the European Union (EU), but this could be changing.

The order was confirmed publicly at the end of September 2025. The subsidiary of ATS Group will supply a solid AF metering and conveying system to the integrated plant in San Antonio, Texas. The system will include a moving floor receiving station, chain belt conveyors, a screen and a separator, dosing equipment, an air-supported belt conveyor and an injection system. ATS Walter says that, by the end of 2026, it will have supplied four AF projects in North America. As an aside, Capitol Aggregates also mentioned in the press release that it “...views sustainability as essential to long-term success.” This sentiment is backed up by the fact that the plant built an early commercial carbon capture unit in the 2010s!

Data from the American Cement Association (ACA) revealed that the AF TSR in the US reached 16% in 2023 from 14.6% in 2022. This compares to a 58% rate in the EU in 2022. It is also worth noting that, in the US the share of gas in the cement industry energy mix rose from 25% to 31%. The ACA attributed this change to a falling price of gas. It added that the coal and petroleum share of the fuel mix fell to its lowest level since 1974. The point here is that the energy mix used by cement plants changes over time regardless of sustainability trends.

Research by LEK Consulting estimated that 60 of the 87 cement plants in the US had a TSR of below 20% in 2023. 39 of these were believed to have a TSR of under 5%. It summarised that hazardous waste and tyre-derived fuels have tended to predominate in the US compared to refuse-derived fuel (RDF) in the EU and elsewhere. LEK went on to say that its research suggested that a quarter of cement plants in the US were likely to install an AF feeding system in 2024 or 2025. This is likely to be the highest rate of AF uptake in the US cement sector to date.

The ACA reckons in its sustainability roadmap that with the right policies and regulations the country’s AF TSR could reach as high as 50%. Its policy suggestions include: reduce permitting barriers to use of so-called non-hazardous secondary materials (NHSM) fuels in industrial manufacturing; treating waste-to-industrial energy as valid recycling use; building robust recycling infrastructure and markets that incentivise the use of non-recycled material streams as industrial AF; community education and support for use of low carbon AF; and increasing the use of NHSMs to divert these materials from landfills. This can be mostly summarised as supporting the uptake of RDF through better permitting and building up the infrastructure and markets for it. LEK also identified the same issue. It called for the adoption of landfill reduction targets or zero-landfill policies by commercial and industrial waste generators. However, LEK believes that, even if this were done, current sources of high-quality RDF in the US would not be able to increase the TSR to even 20%.

News from Capitol Aggregates and others about AF projects in the US are encouraging. If LEK’s research is indicative then a step change in the TSR in the country’s cement sector is already underway. The beauty of AF usage is that it can both potentially cut fuel costs and reduce CO₂ emissions. It won’t be easy as new supply chains for refuse byproducts are built and utilised. Yet, as the ACA is advocating, it is possible and worthwhile.

Renewables reportedly generated more power than coal in the first half of 2025. Energy think tank Ember put out a report this week, which showed that solar and wind generation also grew faster than the rise in electricity demand in the first half of 2025. Global electricity demand rose by 2.6% year-on-year, adding 369TW. Solar increased by 306TW and wind by 97TW. Both coal and gas generation fell slightly, although a rise in other fossil fuel generation slowed the decline further.

Tellingly, fossil fuel generation fell in both China and India. Indeed, China added more solar and wind than the rest of the world combined, cutting its fossil fuel generation by 2% or by 58.7TWh. In India, renewables grew at the expense of fossil fuels, but demand growth was relatively low at 12TWh. In the US and the European Union (EU) fossil fuel generation actually increased. In the US, this was due to demand growth outpacing new renewable power. In the EU, weaker wind and hydroelectric output led to a greater reliance on coal and gas.

Meanwhile, a separate report by the International Energy Agency (IEA), also out this week, predicts that installed renewable power is likely to more than double by 2030 even as the sector navigates headwinds in supply chains, grid integration and financing. The IEA forecasts that global renewable power capacity will increase by 4600GW by 2030, roughly the equivalent of adding the total power generation capacity of China, the EU and combined. Solar photovoltaic (PV) will account for around 80% of the global increase in renewable power capacity over the next five years, followed by wind, hydroelectric, bioenergy and geothermal. Solar PV is expected to dominate renewables’ growth between now and 2030, remaining the lowest-cost option for new generation in most countries. Wind power, despite its near-term challenges, is still set for considerable expansion as supply bottlenecks ease and projects move forward, notably in China, Europe and India. However, the IEA’s outlook for global renewable capacity growth has been revised downward slightly compared to 2024, mainly due to policy changes in the US and in China.

This is all very well but what does it mean for the cement sector? At face value, possibly not much anytime soon. Both Ember and the IEA are talking about domestic electricity generation, not industrial. Ember reckons that half the world’s economies may have already peaked in fossil fuel power generation, but usage rates are still high. Prices of fossil fuels may even subsequently come down - to the benefit of industrial users such as cement plants. Yet, carbon taxes should, in theory, discourage increased usage - if they are working correctly.

Market distortions should not be discounted though. Some readers may recall what happened with carbon credits in the earlier stages of the EU emissions trading scheme. Free carbon allowances, calculated during the boom years of 2005 - 2007 when production was maxed out, were far too much to cover production during the resulting economic crisis. The sale of extra allowances provided many plants with a nice little earner and did little to encourage decarbonisation. Carbon capture is likely to require large amounts of electricity, but cheaper energy from renewables may help.

However, take a look at renewable energy stories in the Global Cement website news so far in 2025 and there are nearly 30 solar-related and seven wind-related ones. Cement companies are busily adding renewable capacity to reduce the cost of their electricity. This week, for example, Equator Energy commissioned a 10MW captive solar power plant at Mombasa Cement’s Vipingo plant in Kenya. Last week, Southern Province Cement in Saudi Arabia signed a 25-year solar energy power purchase agreement for its Bisha cement plant. Lest one forget, Saudi Arabia was the largest exporter of crude oil among Organization of the Petroleum Exporting Countries (OPEC) members in 2023 at 6,659,000 barrels/day. If a cement plant in Saudi Arabia is investing in renewables, then one might suspect a change in the global energy mix is occurring.

Electricity accounts for around 12% of the energy demand at a cement plant. Nearly two-thirds of that demand comes from either grinding raw materials or cement. Then, as mentioned above, carbon capture is expected to increase the demand for electricity. One estimate reckons it will increase electricity consumption by 50 - 120%. Renewables are expected to bring down the price of electricity but demand will also grow.

So… expect more renewable projects linked to cement plants.

There have been a few burner and related stories to note in the cement industry news this week. Firstly, Canada-based PyroGenesis announced that it had signed a deal with an unnamed-European cement company to supply a plasma torch system for a ‘calcination furnace.’ Around the same time UBE Mitsubishi Cement (MUCC) revealed that it had successfully tested natural gas co-firing at MUCC’s Kyushu Plant using a newly developed burner.

The PyroGenesis project is a potential game-changer for the sector because it alters the way cement production lines are heated. Roughly one third of CO₂ emissions associated with cement manufacture arise from the fossil fuels used to heat the kiln and the pre-calcination system. Cut out some of that and the specific CO₂ emissions of cement production drop. PyroGenesis’ approach uses electricity to generate high-temperature plasma. This then gives the cement plant the option of obtaining its electricity from renewable sources. PyroGenesis signed a memorandum of understanding with the power conversion division of GE Vernova in March 2025. This had the aim of targeting high temperature processes, such as cement production, with electric plasma torches. The current deal with a cement producer has been valued at US$871,000 with delivery to the client scheduled for the first quarter of 2026.

We don’t know who the mystery client might be. However, Heidelberg Materials reportedly operated a 300kW plasma-heated cement kiln at its Slite cement plant in February 2025 as part of the ELECTRA project. The producer said it had achieved 54 hours of continuous operation, with 60% CO₂ concentration in the flue gas. The aim was to reach 99%. It then said that it was planning to build a larger 1MWel furnace at its Skövde cement plant in 2026 with tests to continue in 2027. In an interview with Global Cement Magazine in May 2025, Heidelberg Materials said that it was using commercially supplied CO₂ as the ionising gas in the plasma generator but that it was considering using captured CO₂ from the production process in the future. It also mentioned issues from its trials such as the effective ‘flame’ being hotter than the conventional process but not as long. This increased the reactivity of the resulting clinker. Finally, Heidelberg Materials noted from a feasibility study that a 1Mt/yr cement plant would need around 170MW of plasma generation, but that typical plasma generators topped out at around 8MW. Hence, any full set-up would likely require multiple plasma generators. For more on non-combustion style kilns see GCW561.

UBE Mitsubishi Cement’s burner installation is more conventional but again it is concerned about sustainability. In this case the line has tested burning natural gas. The cement producer says it is the first such installation at a cement plant in Japan to do so commercially. The burner was jointly developed by UBE Mitsubishi Cement, Osaka Gas and Daigas Energy. Firstly, the plant will consider switching to natural gas. This will reduce the unit’s CO₂ emissions from fuel combustion. However, a later step being considered is to move on to e-methane. This is a synthetic methane made from CO₂ and hydrogen using renewable energy.

Finally, another recent story on this theme is the installation of a new satellite burner by Northern Ireland-based Mannok at its Derrylin cement plant in August 2025. This is Phase One of a two-part project to upgrade the pyro kiln system at the site. The cement company worked with FLSmidth on the €2.5m upgrade. The new burner has now allowed the plant to burn solid recovered fuel (SRF) by up to a 30% substitution rate in the kiln. This followed a project, also with FLSmidth, to install a FuelFlex Pyrolyzer in 2022. This is used to replace coal with SRF in the pre-calcination stage of cement production. Phase two will be an upgrade of the main burner to a new Jetflex burner. Once this part is completed, Mannok is aiming for an overall substitution rate of 65 - 70% on the whole pyro-processing system.

Burners at cement plants are replaced fairly commonly. However, the supplier companies don’t advertise every installation due to the commercial relationships with their clients and other factors. Hence the more interesting upgrades tend to get the publicity. Typically this means if a burner uses new technology, meets sustainability goals and so on, we find out about it. It’s a similar situation when a new heating technology such as plasma is trialled. Changing trends in fuel types for cement plants suggest different types of conventional burners. Some of this can be seen in the burner stories above with the trend moving towards ever higher rates of alternative fuels usage. Combustion in cement kilns is here to stay for the time being but plasma trials will be watched carefully.

The 18th Global CemFuels Conference & Exhibition on alternative fuels for cement and lime 2025 will take place in Milan on 17 - 18 September 2025

Japan: Mitsubishi UBE Cement Corporation (MUCC), Osaka Gas, Daigas Energy and Saibu Gas have successfully tested natural gas co-firing at MUCC’s Kyushu Plant in the Kurosaki area. Using a newly developed burner, the companies replaced 40% of coal with natural gas at commercial scale without affecting kiln stability, product quality or environmental performance.

The burner was developed using MUCC’s coal combustion expertise alongside Osaka Gas and Daigas Energy’s gas combustion and simulation technologies, with Saibu Gas supplying natural gas from LNG tank trucks. MUCC said the trial paves the way for full-scale implementation and supports future use of e-methane in cement kilns.

MUCC aims to cut CO₂ emissions by 40% by 2030, compared to 2013 levels, and achieve group-wide carbon neutrality by 2050 under its medium-term management strategy “Infinity with Will 2025 – MUCC Sustainable Plan 1st STEP.”

Najmat Al Samawa Cement (NAS Cement) in Iraq announced this week that its second production line was successfully fired up on 13 May 2025. The new 5500t/day line was formally announced in May 2023. It joins the existing line at the site and should bring the plant’s total production capacity to around 3Mt/yr. The plant is a joint-venture between Pakistan-based Lucky Cement Limited and the Al Shumookh Company in Dubai and its representatives in Iraq.

Global Cement Magazine interviewed Intezar Ahmad, the Director of Operations at NAS Cement, in the November 2024 issue. He explained that China-based TCDRI was the main contractor for both the original and new lines. Equipment for Line 2 was also supplied by Fives Pillard, Loesche and IKN. Commissioning was scheduled for the second quarter of 2025. This, nicely, appears to be spot on. Lucky Cement added in its statement about the new line this week that it is also building a new 0.65Mt/yr cement grinding mill at the plant. This addition is expected to be commissioned during the second half of the 2025 calendar year. Lucky Cement also operates a cement grinding plant, under a joint-venture, in Basra.

The expansion at NAS Cement is by no means the only one as there have been a number of project announcements over the last three months. Germany-based Gebr. Pfeiffer revealed in late-March 2025 that it had won an order to supply a vertical roller mill for the Al Amir cement plant in Najaf. This contract was awarded through the China-based contractor Sinoma Suzhou. Commissioning is planned for the second half of 2026. Then, one month later in April 2025, Prime Minister Mohammed Shia Al-Sudani made a statement launching ‘implementation works’ at four cement plants in Al-Muthanna Province. This included the 6000t/day Al-Arabi Cement Plant, the 6000t/day Al-Khairat Al-Muthanna Cement Plant, the 6600t/day Al-Samawa Cement Plant and the 6000t/day Al-Etihad Cement Plant. Al-Sudani also mentioned the start of commercial operations at NAS Cement’s second line. Subsequently, IVI Holding signed a US$240m deal with Sinoma Overseas in mid-May 2025 to build a 6000t/day plant in Al-Muthanna Province. Presumably, this is one of the projects that the government highlighted. Finally, the Kurdistan Region prime minister Masrour Barzani inaugurated the 6300t/day Dabin cement plant at around the same time. This last project was built by PowerChina together with a power station.

The Iraqi economy has been doing well in recent years. The International Monetary Fund (IMF) reported in May 2025 that the non-oil sector experienced “very strong growth” of 13.8% in 2023. This slowed down to 2.5% in 2024 due to a slowdown in public investment and in the services sector, and a weaker trade balance. However, the IMF noted that the agriculture, manufacturing, and construction sectors had remained resilient. Non-oil sector growth is forecast to remain subdued in 2025 amid a “...challenging global environment and financing constraints.” In its coverage of the new line at NAS Cement, Pakistan Today reported that the country has a notional cement production capacity of around 40Mt/yr but that many of the older plants have suffered from under-investment. Accordingly, the domestic market is around 25Mt/yr supported by state-funded housing projects, oil-field infrastructure schemes and reconstruction in Mosul. 3 - 4Mt of this is supplied via imports from Iran and Türkiye. The newspaper also noted the risk that all these new cement plant projects may face from variable gas supplies from the government. NAS Cement, for example, switched from heavy fuel oil (HFO) to gas in 2022.

Cement sector capacity expansion is coming in Iraq following a revived local economy. Risks abound though due to the country’s economic outlook, its dependence on oil and an geopolitical uncertainty. Yet money is being spent and new projects are starting to be commissioned. Onwards!

Bangladesh: Chhatak Cement’s plant in Sunamganj remains idle despite construction completing in March 2023, with production suspended due to unresolved gas and limestone supply issues, according to the Prothom Alo newspaper. The plant project began in 2016. New details confirm that the Bangladesh government has approved subcontracting of a cross-border ropeway to import limestone from India. Local firm Komorah Limestone Mining Company (KLMC), which already supplies limestone to Chhatak Cement, is in talks regarding the role. China-based contractor for the project, Nanjing Sea-Hope Cement Engineering, has agreed ‘in principle’ to this handover as of 18 March 2025, according to Chhatak Cement managing director Abdur Rahman.

Project officials stated that, once the new plant begins operations, it will be capable of producing 1500t/day of clinker and 500t/day of cement, triple its previous capacity. Reporters conducted a site visit on 8 April 2025, observing that a jetty had been constructed on the riverbank to unload clinker from the plant for grinding elsewhere. A conveyor system has been set up to move cement bags directly from the plant to transport, and a new conveyor belt has also been installed alongside the existing belt.

Bangladesh: Chhatak Cement Factory has ceased production due to severe gas and limestone shortages, despite a modernisation project having reached 91% completion.

The Bangladesh Chemical Industries Corporation (BCIC) began a US$54.7m project to convert the plant’s production process from wet to dry in 2016, in order to increase capacity to 1500t/day (0.45Mt/yr). The project cost rose to US$116m, with US$68m spent by November 2024. However, the plant remains idle despite the completion of construction works over a year ago, due to the lack of a new gas pipeline and ropeway to import limestone from India. This ropeway was supposed to transport limestone from the Komorrah Limestone Mining Company in Meghalaya.

The project's committee has proposed extending the deadline to June 2026 and allocating an additional US$25m for a 43km gas pipeline from Sylhet to Chhatak. Trial runs are now being conducted every 15 days in order to prevent the plant’s machinery from rusting.

Project director Abdur Rahman Badsha said that the Chinese contractor responsible for the ropeway construction, Nanjing C-Hope Cement Engineering Group, is awaiting a subcontracting agreement with KLMC to begin work in India.

Alpacem said this week that it had completed its acquisition of the Fanna cement plant near Pordenone. The 0.66Mt/yr integrated plant and a number of ready-mixed concrete plants became part of the Austria-headquartered group at the start of February 2025. Alpacem now has three integrated plants, with units at Wietersdorf in Austria and Anhovo in Slovenia, in addition to Fanna.

The deal dates back to mid-2023 when Alpacem said it had signed an agreement with Buzzi. In return Buzzi was set to receive a 25% stake in Alpacem Zement Austria. Prior to this the two companies had a strategic partnership in Austria and Slovenia that dated back to 2014. At the time of the agreement Buzzi held a 25% share in each of two Alpacem subsidiaries: Salonit Anhovo in Slovenia; and W&P Cementi in Italy. The Fanna plant was originally owned by Cementizillo before it was bought by Buzzi in 2018.

Also this week, Federbeton warned that the high cost of gas would add €80m/yr to the cost of cement production. Nicola Zampella, General Manager of Federbeton and the cement association AITEC, noted that local energy costs would reduce the competitiveness of producers against imports from outside of the European Union (EU). This ties into comments Stefano Gallini, the president of Federbeton, made in December 2024 when he highlighted the growing share of imports from outside the EU.

Federbeton raised the issue in its annual report for 2023, showing that imports rose to a 19% production share in 2023. Italy produced 18.8Mt of and imported 3.6Mt of cement and clinker in 2023. This is its highest level of imports for at least a decade. Over the same period the country’s cement exports, as a share of production, have remained steady at around 10 - 11%. In 2023 Türkiye was the biggest source of imports (25%) followed by Greece (17%), Slovenia (17%), Tunisia (12%) and Algeria (10%).

It is worth recalling that the cement sector in Italy used to be larger before it started consolidating in the late 2000s. Italcementi was acquired by Germany-based Heidelberg Materials. Operations by Sacci, Cementir and Cemenzillo were all bought out too. Local cement production reached a high of 47.9Mt in 2006 before it stabilised at around 20Mt/yr from 2015 onwards.

In its preliminary results for 2024, out this week too, Buzzi reported that the construction market In Italy probably shrank in 2024 due to a poor residential housing market. However, the cement company managed to keep its local net sales stable by raising prices and focusing on exports. Despite this, it noted a drop in cement and concrete sales volumes at the end of 2024. More data on the construction market in Italy may emerge when Heidelberg Materials releases its 2024 financial results at the end of February 2025.

The backdrop to this has been a rise in gas prices in Europe towards the end of 2024 as the EU ‘emergency’ price cap finished on 31 January 2025. Around the same time the EU is preparing to reveal information on its Clean Industry Deal towards the end of February 2025. Plus, the first active phase of EU Carbon Border Adjustment Mechanism (CBAM) is preparing to enter into force from the start of 2026. Each of these issues has implications for the cement sector in Italy as the location associations have been highlighting. One question will be whether the Clean Industry Deal can help producers cope with mounting energy prices. Another will be whether CBAM will change the proportion of imports for countries like Italy or will the sources of the imports simply change. Plenty to consider for the year ahead.

Italy: Federbeton, the Italian cement association, has expressed alarm that the high price of gas is adding €80m/yr to the cost of cement production. Nicola Zampella, the general manager of Federbeton, called for an ‘urgent’ change to the national energy system to make it more equitable, sustainable and competitive, according to Adnkronos. He recommended energy diversification, further encouraging the use of alternative fuels, simplifying regulations, making investing and supporting sustainable technologies easier and adding incentives to use carbon capture and storage.

Moldova: The Rybnitsa cement plant has closed amid a cutoff of gas supply to the Transnistrian region, leaving half of its 650 employees at home with 66% of their pay, while the rest carry out equipment repairs and cleaning, according to IPN news.

Interim director Oksana Baka said “The plant had a plan to produce about 30,000t of cement during this period. This stock would have ensured our protection on the market, but now the situation is critical because our supplies are insufficient.” Contributions to the local budget will decrease if gas supplies are not restored by February 2025.

The plant is modernising its dust filtration system and preparing for resumption once gas supplies are restored. On 1 January 2025, Gazprom stopped supplying gas to the Transnistrian region, after gas transit through Ukraine ended. The region remains under a state of emergency until 8 February 2025.
