Taiwan Cement Corporation (TCC) has struck a deal to take control of the Türkiye and Portugal-based parts of OYAK’s cement business. The arrangement will see TCC grow its share of the joint-venture business in Türkiye to 60% from 40% at present and it will fully take over the Cimpor joint-venture in Portugal by purchasing OYAK’s 60% stake. Overall TCC is expected to pay around Euro740m for its acquisitions. A final agreement on the deal is expected to be signed in early December 2023.

The proposed deal follows on from when TCC originally spent US$1.1bn towards setting up joint-ventures as a junior partner with OYAK back in 2018. The situation now appears to have reversed with TCC becoming the main owner of the cement business in Türkiye and the sole owner of Cimpor in Portugal. In Türkiye this gives TCC control over the largest cement producer with seven integrated plants, three grinding plants, 47 ready-mixed concrete (RMX) plants, three aggregate quarries and one paper packaging plant. In Portugal (and Cape Verde) this puts TCC in charge of three integrated plants, two inactive grinding plants, 42 RMX plants, 15 quarries, two mortar plants and a cement bag unit.

This contrasts with last week’s news that CRH is buying one cement plant in Texas (with associated assets) for US$2.1bn. TCC is taking control of 10 plants in Türkiye and Portugal for Euro740m. It is not a fair comparison given the woes of the Turkish economy in recent years, prior joint-venture business ownership and so on. Yet it is one more example of the changing nature of cement company ownership around the world since the mid-2010s.

The state of the economy in Türkiye may well be a factor for the change in ownership at OYAK and Cimpor as well as negative exchange rate trends. High inflation has caused problems in recent years, although the government changed its stance on avoiding putting up interest rates following the elections in May 2023. Yet, in a statement about the OYAK deal, chair Nelson Chang said that “companies that do not understand carbon will not survive in the future.” His company is about to spend Euro740m and become the fifth largest cement producer in the world on the assertion that it does understand carbon. Good luck!

Accordingly, the language in the press releases both OYAK and TCC have released is all about sustainable growth and reducing carbon emissions. However, the detail on how exactly they intend to do this is vague. What is clearer though is that OYAK is hoping that TCC invests in energy storage and related industries such as lithium-ion battery additive carbon black in Türkiye. To this end a TCC subsidiary and OYAK are collaborating on a carbon black plant in Iskenderun and further investments may be in the pipeline. TCC and OYAK are also responsible for a couple of calcined clay projects in Sub-Saharan Africa.

Readers may recall that the chair of Chang pronounced in June 2023 that TCC was aiming to diversify the business towards over 50% sales from non-cement sectors by 2025. However, the share from the cement business was around 68% in 2022 and this latest deal with OYAK will likely send it in the ‘wrong’ direction. The company already has a production capacity of around 77Mt/yr from its cement plants in China and Taiwan. Majority ownership of OYAK Çimento and Cimpor Portugal will bump this up to 99Mt/yr and put the company into the top five of the world’s largest cement producers by capacity.

The final question here is what kind of owner TCC intends to be to its growing cement businesses in West Asia and Europe. Publicly at least, it has come across as a backseat investor since 2018 although it has been a minority owner. This has now changed but it will be interesting to observe whether the subsidiaries in the west will be run at arm’s length or more closely and if TCC unifies its global branding and so on. Watch this space.

Ghana: CIMPOR has appointed Germany-based ThyssenKrupp Polysius to build a 1280t/day flash activator for clay. The activator will supply calcined clay for use in the production of cement with a clinker factor as low as 50%. This can reduce the cement’s CO₂ emissions by 40% compared with ordinary Portland cement (OPC). The supplier’s contract covers engineering, supply of core equipment and supervision of the project. The equipment includes parts for clay handling, a hammer mill, a flash dryer and preheating and cooling equipment, as well as storage silos. The activator will be natural gas-fired.

Polysius Activated Clay product owner Leo Fit said "Our technology is not only more environmentally friendly, but also creates cost benefits for our customers like CIMPOR. In many regions, limestone is scarce and clinker has to be imported at high cost. At the same time, suitable clay sources are available. The increasing pressure to reduce greenhouse gas emissions is leading cement manufacturers to rethink. They need an alternative that is cost-efficient and at the same time provides high-quality cement. This is exactly what Polysius activated clay offers."

Türkiye: Cimpor Global Holdings has appointed Erol Tosun as Operational Technologies Unit Manager. He worked as Operational Technologies Chief for OYAK Çimento since 2019 and was the Information Technology Chief for OYAK Modern Beton from 2005 to 2019.

Other appointments at Cimpor Global Holdings include the move by Burak Demir to Industrial Digitalisation Unit Manager. He previously worked for OYAK Çimento since 2017 in a number of process roles. Prior to this he worked for Cementir in Türkiye.

Pınar Özmen Söylemez has been appointed as Data Analytics & Planning Unit Manager. She has worked for OYAK Çimento since 2017 first as a Performance Controller and then Industrial Program and Analysis Chief. Before this she worked for Votorantim Cimentos for two years.

Portugal: Cimpor Portugal has signed a contract with Germany-based KHD Humboldt Wedag (KHD) for an upgrade to production line 7 at its Alhandra cement plant. The project is intended to increase the production capacity at the plant to 3600t/day from 3000t/day and increase the line’s alternative fuels thermal substitution rate to over 80%. It will also be the first installation of KHD’s Pyrorotor alternative fuel combustion reactor in the country.

The scope of the engineering and supply contract comprises:

• New HKSK 224/335 preheater ID fan
• New downcomer duct
• New preheater with 8064/5-type HEM cyclones
• Pyroclon R calciner with Pyrotop mixing chamber. The Pyroclon R will utilize fine refuse-derived fuel (RDF) and natural gas
• 4m x 10m Pyrorotor alternative fuel combustion reactor
• Pyrobox coal firing system for process start-up and operation balancing
• Shortening of the existing kiln and installation of new kiln inlet chamber with bypass extraction
• New kiln drive station 2 (the existing girth gear and two pinions will be reused)
• New kiln hood and take-off of tertiary air from the cooler roof
• New main kiln burner designed to use more than 50% alternative fuels (but will also be capable of burning natural gas, as well as liquid fossil and alternative fuels)
• New Pyrofloor PFC²829AW cooler with a Pyrocrusher PRC 420-3ES clinker crusher.

KHD will also be supplying its KHD ProMax software product as part of the project.

Matthias Mersmann, chief technology officer at KHD, said “The decision by Cimpor Portugal to opt for KHD pyroprocessing equipment - and especially the Pyrorotor - underlines the leading market position of KHD, as well as the outstanding capability of KHD’s unique alternative fuel-processing solution.”

Project execution will be led by KHD Germany, with support from Humboldt Wedag India and the Turkish branch office of Humboldt Wedag. Commissioning of the upgraded production line is scheduled for 2025.

Taiwan Cement said this week that it is aiming for cement to account for less than half of its sales by 2025. At the annual shareholders’ meeting chair Nelson Chang defended the cement sector as a core business but said that the company was expanding more into the green energy sector through its energy storage and vehicle charging lines. Chang directly linked the strategy to growing carbon taxes around the world, such as the European Union Emissions Trading Scheme, where the carbon price has been occasionally close to pushing past Euro100/t since early 2022. Taiwan Cement formed a joint venture with Türkiye-based Oyak Group in 2018 that runs Cimpor in Portugal.

Taiwan Cement’s plan to decrease its reliance on cement is becoming a familiar one. Holcim notably revealed in 2021 that it was growing its light building materials division. Its cement division represented 60% of sales in 2020 with concrete and aggregates making up most of the rest to 92% and the remaining 8% on other products including light building materials. This started to change with the acquisition of roofing and building envelope producer Firestone Building Products in 2021. Other similar acquisitions have followed. Holcim’s current target is to grow the Solutions & Products division to around 30% by 2025, with cement reduced to somewhere between a third and half of sales. Earlier this year Japan-based Taiheiyo Cement said it was doing a similar thing as part of its medium-term strategy to 2035. In its case cement represented 70% of its sales in 2022 but it is now aiming to reduce this to 65% by 2025 and 50% by 2035.

A common pattern for the business composition of European cement companies is a mixture of heavy building materials made up of cement, concrete and aggregate. However, not every cement company follows the same route. Some cement companies are simply parts of larger conglomerates. UltraTech Cement, for example, is mostly just a cement company. However, it is also part of Aditya Birla Group, which runs a wide range of industries including chemicals, textiles, financial services, telecoms, mining and more. Depending on how one looks at it, UltraTech Cement’s cement business ratio is large or Aditya Birla Group’s ratio is small. Siam Cement Group (SCG) in Thailand is another example of a cement producer operated by a conglomerate with other major businesses.

A different approach that some cement producers take is to mix cement production with complimentary businesses outside of heavy building materials. A good example of this is Votorantim Cement in Brazil, which manufactures cement and steel. Companhia Siderúrgica Nacional (CSN) is another Brazil-based cement producer that is also well known for steel production. Adani Group in India, meanwhile, was well known for logistics, power generation and airports before it purchased Ambuja Cements and ACC from Holcim in 2022.

The driver for cement companies looking to reduce cement as a proportion of their businesses has varied between the three examples presented above. Holcim’s approach has been in response to growing European carbon costs but it also fits with a general desire to broaden its business as the company has sought to reshape itself following the merger between Lafarge and Holcim. Taiheiyo Cement’s plans also have a sustainability angle but the Japanese market has been in slow decline since the 1990s and this has been made worse by the spike in energy prices since 2022. Investing in new businesses makes sense for either of these reasons. Lastly, Taiwan Cement says it is taking action in response to carbon prices around the world. However, its proximity to many other large-scale producers in the Far East may also be a factor. Whether more companies follow suit and also start to reduce the ratio of their cement businesses remains to be seen. Yet, mounting carbon taxes and global production overcapacity look set to make more of the larger cement producers consider their options in certain places.

Cape Verde: Portugal-based Cimpor has signed a deal with the government of Cape Verde to develop and exploit a pozzolan deposit over the next 30 years. Exploration of the site is expected to begin by late 2024. The immediate location has reserves of around 0.5Mt in an area of 108 hectares. However, the scheme also has the option to expand the site to 790 hectares, increasing the estimated pozzolan reserves to 4Mt. The project has an investment of Euro3m and is expected to create around 80 jobs.

Cimpor’s parent company OYAK Cement previously said in 2019 that it was planning to invest in pozzolan extraction in Cape Verde.

African cement producers have confirmed their interest in calcined clay over the last month with two new projects. The big one was announced last week when FLSmidth revealed that it had received an order from CBI Ghana. This follows the launch of a Limestone Calcined Clay (LC3) project in Malawi in mid-March 2022 in conjunction with Lafarge Cement Malawi.

FLSmidth says that its order includes the world’s largest gas suspension calciner system and a complete grinding station. The kit will be installed at CBI Ghana’s plant near Accra in the south of the country. The new clay calciner system is expected to substitute 30 - 40% of the clinker in the final product, resulting in a reduction of up to 40% CO₂/t of blended cement compared to Ordinary Portland Cement (OPC). Overall the equipment manufacturers reckon that the grinding plant will reduce its CO₂ emissions by 20% compared to its current output. There has been no indication of how much the order costs but CBI Ghana expects energy and fuel savings, as well as lower overheads from clinker imports.

The public announcement of the Ghana project was also foreshadowed by the visit of Professor Karen Scrivener to the Ghana Standards Authority in February 2022. This was significant because Scrivener is the head of the Laboratory of Construction Materials at the Ecole Polytechnique Fédérale de Lausanne (EPFL) and has been one of the key instigators of the LC3 initiative since the early 2000s. Other calcined clay cements are available such as Futurecem or polysius activated clay (see below) but LC3 is arguably the most famous given its promotion in developing countries.

The Malawi project is at a much earlier stage. The government launched the public private partnership LC3 project in mid-March 2022 in conjunction with Lafarge Cement Malawi and Terrastone, a brick manufacturer. The Ministry of Mining is currently developing a memorandum of understanding with the Gesellschaft für Internationale Zusammenarbeit (GIZ), a Germany-based development agency. India-based Tara Engineering has also been linked to the scheme.

One thing to note about the Malawi project is that it is the first calcined clay project in the cement industry based in East Africa. All the other African ones are based in West Africa. The other two projects in this region are run by Turkey-based Oyak Çimento and its subsidiary Cimpor. The first of these is a 0.3Mt/yr calcined clay and a 2400t/day cement grinding production line that was commissioned in mid-2020. This plant is based at Abidjan in Ivory Coast. The second is a new plant that Germany-based ThyssenKrupp Industrial Solutions is building for Oyak Çimento at Kribi in Cameroon. This unit has a 720t/day calcined clay and a 2400t/day cement production capacity and it will use the supplier’s ‘polysius activated clay’ technology. ThyssenKrupp’s involvement came to light in early 2020 and commissioning was scheduled for late 2021. However, no update on the state of the project has been issued so far in 2022.

As the above examples show, Sub-Saharan Africa has at least one live calcined clay plant, two plants are being built and there’s one more at the development stage. This puts the region neck-and-neck with Europe, which has a similar mixture of current and developing projects. This column has been covering the wider trend of the growing usage of various types of blended cements recently, particularly in Europe and the US, with slag cements, Portland Limestone Cement (PLC) and more. With PLC, for example, note the transition of another two North American cement plants to PLC this week alone. As for calcined clay cement, it is fascinating to see the focus move to a different part of the world. Several commentators have predicted that the future looks set to be dominated by blended cements using whichever supplementary cementitious material (SCM) is most available for each plant. The growth in calcined clay confirms this view.

Portugal: Cimpor is participating in a consortium, led by power company Rega Energy, which plans to invest Euro100m in developing scalable green hydrogen production plant technologies. The consortium will deploy infrastructure for its upcoming Vale Hidrogénio Verde Nazaré (NGHV) green hydrogen plant by 2023, including a dedicated 40MW solar-powered electricity grid. It will commission its first green hydrogen plant by 2026, creating 140 new jobs. The consortium aims subsequently to scale up the plant to a renewable power consumption of 600MW. It hopes that, when fully commissioned, the NGHV plant will be a reference project for green hydrogen production.

Portugal: Cimpor has announced plans for the establishment of 1MW solar power plants at each of its three cement plants in Portugal. The Dinheiro Vivo newspaper has reported that the measure comes under a planned Euro130m investment package in upgrades to its cement operations before 2030. The plans include the expansion of the solar power plants to a total capacity of 10MW by 2025. Additionally, the producer will install two waste heat recovery (WHR) plants with a combined capacity of 8MW at its Alhandra and Souselas cement plants. The company is aiming to reduce its indirect CO₂ emissions by 30%. It also has an alternative fuel (AF) substitution rate target of 70% by 2030 - compared to 3% in 2020, when it used 150,000t of AF.

Cimpor has previously invested a total of Euro7.2m in dedicated sustainability-related measures.

The latest piece of China-based Huaxin Cement’s global ambitions slotted into place this week with the news that it is preparing to buy plants in Zambia and Malawi. Its board of directors has approved plans to spend US$150m towards acquiring a 75% stake in Lafarge Zambia and US$10m on a 100% stake in Lafarge Cement Malawi. The move will gain it two integrated plants with a combined production capacity of 1.5Mt/yr in Zambia, and a 0.25Mt/yr grinding plant in Malawi.

This latest proposed acquisition represents the next step for Huaxin Cement in Africa following its purchase of African Tanzanian Maweni Limestone from ARM Cement in mid-2020. The company has also been busy along the more traditional Belt and Road Initiative land routes in Asia. It started up the kiln at its new 2Mt/yr Jizzakh cement plant in mid-2020. Elsewhere in Central Asia it runs two plants in Tajikistan and one plant in Kyrgyzstan via various indirectly-owned subsidiaries. While in South Asia it runs a plant in Nepal and in South-East Asia it runs one in Cambodia. If the plans in Zambia and Malawi pay off then it will give the Chinese producer a growing presence in East Africa, with plants in three countries.

The China Cement Association ranked Huaxin Cement as the country’s fifth largest clinker producer in 2021 with an integrated capacity base of just under 63Mt/yr. Domestically, the company operates 57 cement plants and most of these are based in the Yangtze River Economic Belt region. In 2020 it reported cement and clinker sales of 76Mt, a small decrease from 2019. Its operating income fell by 6.6% year-on-year to US$4.58bn and profit dropped by 12% to US$1.2bn. This performance was blamed on the emergence of Covid-19 at the start of 2020 and then floods later in the year.

Compared to the other larger Chinese cement producers, Huaxin Cement roughly appears to be holding rank with its overseas expansions. The leaders, CNBM and Anhui Conch, hold subsidiaries with plants in South-East and Central Asia and CNBM’s engineering wing, Sinoma, has a far bigger reach, building plants all over the place. Information has been scarce since mid-2020 on the long heralded 7Mt/yr plant in Tanzania due to be built by Sinoma and local subsidiary Hengya Cement. At that time local residents in Mtimbwani, Mkinga District were reportedly being compensated for their land. Other than this, one of the other big players internationally is Taiwan Cement. In 2018 it invested around US$1.1bn for a 40% stake in Turkey-based Oyak Cement. As well as a presence in Turkey this also gave it a share of plants in Portugal in 2019 when Oyak completed its acquisition of Cimpor.

Elsewhere this week, carrying some of the themes above with expansion in Central Asia, two new integrated cement plant projects were announced in Kyrgyzstan and Turkmenistan respectively. Meanwhile, Italcementi said it will invest Euro5.0m to restart clinker production at its Trentino cement plant in Sarche di Madruzzo, Italy. The unit has been operating as a grinding plant since 2015. This might be viewed as an unexpected decision considering the high local CO2 price but it shows some level of confidence in the local market by Italcementi and its parent company, HeidelbergCement. The next step will be when or if a European producer decides to build a brand new integrated plant in Italy or elsewhere.
