Heidelberg Materials Sweden calls for faster upgrade to electrical connection to Gotland
31 May 2023Sweden: Heidelberg Materials Sweden has called for swifter action to be taken by the government on a planned upgrade to the mains electricity supply to the island of Gotland. The building materials company is planning to build a full-scale carbon capture and sequestration (CCS) unit at its integrated Slite cement plant on the island by 2030. However, the newly approved plans to build two new electrical transmission cables to Gotland are currently scheduled for completion in 2031. The cement plant is expected to require annual electricity requirements of up to 1.5TWh with a power requirement of up to 250MW when the CCS unit is completed.
The cement producer has welcomed the government’s upgrade plans so far but has impressed the urgency of its timeline to build a CCS unit at the Slite plant. It says it is currently considering investing around Euro850m on the project. If completed the CCS unit is expected to capture up to 1.8Mt/yr of CO2. The company said that this corresponds to approximately 3% of Sweden's emissions annually.
Update on Saudi Arabia, May 2023
24 May 2023Sinoma International Engineering was revealed this week as the winner of a contract to build a new production line at Southern Province Cement’s Jizan plant. The China-based engineering firm said that the US$330m contract was to build a full line, from limestone crushing to bagging, with an output of 5000t/day. The construction period is expected to take just over two years, suggesting a commissioning date in mid-2025 if work starts now. The project has been in the pipeline for a while with an announcement in mid-2021. It was previously reported that the new line is intended to replace the two existing production lines at the site once completed.
Other recent projects in the country include Yamama Cement’s plans to move its cement plant near Riyadh to a new location. Sinoma International Engineering was also selected as the main contractor in November 2022 for the US$220m project. The relocated line – using both old and new equipment – will have a production capacity of 10,000t/yr. Project duration was estimated at around two-and-a half years following financial contractual commitments. So the earliest this one might be completed is also mid-2025. Eastern Province Cement also started making moves to build a new major upgrade in March 2023 when it started the tendering process for a planned 10,000t/day production line at its Al Khursaniyah Plant. The intention is to replace some of the obsolete lines at the unit. The project dates back to 2015, when it was first announced.

The timing of these new projects is compelling given that sales by the local industry peaked in 2015. They declined in 2018 to a low of around 40Mt before stabilising at around 50Mt for the last three years. However, one trend to note is how clinker exports reached 7.1Mt in 2022, the highest figure in a decade, since export rules were relaxed in 2017. They have grown year-on-year since 2018 with the exception of 2020. Cement exports have been lower since 2013 hitting a high of 1.9Mt in 2019, although 2022 was nearly as good at 1.8Mt.
The other big news story from the local sector in 2023 was the US$37m fine that the General Authority for Competition (GAC) levied for price fixing in April 2023. 14 of the 17 main cement companies in the country were found to have broken local competition law following an investigation. Detail on specifically what happened is light, but the GAC said that it took exception to companies “controlling prices of commodities and services meant for sale by increasing, decreasing, fixing their prices or in any other manner detrimental to lawful competition.”
As ever with the Saudi construction market, government spending is expected to keep things buoyant. Although input and logistic costs have risen like everywhere else, energy costs have also risen. This, no doubt, is useful to a government planning on building a bunch of so-called ‘Giga’ projects. Local sales of cement may have dipped slightly in 2022 but building all these big new projects will require plenty of cement. A report by the SICO Bank in January 2023 forecast that local cement demand was expected to remain ‘flat’ in 2023 but that it would grow by 5% year-on-year in 2024. Interestingly, it added that demand from the tourism and exhibition sector would also fuel demand in the run-up to 2030 as various schemes connected to the ‘Giga’ projects reached fruition.
Each of the three projects detailed above are intended to replace existing capacity. This suggests that none of these companies expect the market to grow significantly anytime soon. These cement producers are likely to be focusing on improving efficiencies from their existing market share. Alongside this, exports of cement and clinker have grown, giving combined local and export sales that are similar to the market peak in 2015. Efficiency savings and adapting to a mature market appear to be the way forward for Saudi cement producers in the near-term.
India: UltraTech Cement has announced a plans to install a RotoDynamic Heater (RDH) supplied by Finland-based Coolbrook at one of its cement plants. The RDH uses renewably powered electrical heat, eliminating the need for cement fuels. UltraTech Cement will initially test the equipment in the drying of alternative fuel (AF) in its existing AF line.
UltraTech Cement managing director Kailash Jhanwar said “As a founding member of the Global Cement and Concrete Association (GCCA), we are committed to the sectoral aspiration of delivering net zero concrete by 2050. Towards this end, we are continuously striving to innovate at every stage of the whole life of concrete. Coolbrook’s RDH technology represents an exciting technological pathway that we believe has the potential to exponentially accelerate our progress towards full decarbonisation. Every megawatt of clean energy we add to our mix makes a big difference.”

Türkiye: Italy-based CTP Team says it is currently installing a new waste heat recovery (WHR) system at Medcem Çimento’s Mersin plant. Its contribution to the construction of a new production line at the site includes installing an organic rankine cycle-based (ORC) 10.5Mwe WHR system and three new process fabric filters for the kiln and raw mill, coal mill and cement mills. The new line is expected to be commissioned in 2024.
US: Continental Cement has ordered a Fuelflex Pyrolyzer alternative fuels combustion system from Denmark-based FLSmidth for installation at its Davenport plant in Buffalo, Iowa. The supplier says that its product offers a lower capital expenditure compared to competing systems, can control NOx emissions without the need for ammonia water and can be installed without a long shutdown period. This is the first commercial installation of the Fuelflex Pyrolyzer system following a pre-commercial installation at the Mannok cement plant in Northern Ireland, UK, in 2022.
David Loomes, the president of Continental Cement, said “We’re very excited about what the Fuelflex Pyrolyzer will do for our process.” He added, “We’re planning to achieve 55% fossil fuel replacement across the plant, utilising non-hazardous waste that would otherwise go to landfill or incinerators. The economic and environmental benefits of this technology are very significant and a key element of executing our carbon reduction commitment.” Continental Cement, a subsidiary of Summit Materials, has been incorporating waste materials as fuels for more than 30 years.
Jens Jonas Skov Larsen, Head of Capital Sales at FLSmidth, said “Mannok has called the Fuelflex Pyrolyzer a game-changer for the cement industry.” He continued, “This system effectively rearranges the order of the combustion process to make use of hot preheater meal, which is the heat source for the waste fuel pyrolysis. It’s a more efficient way of burning alternative fuels and it comes with a host of benefits, including reduced emissions and a more stable process.”
The installation at Davenport cement plant is expected to start operation in 2024. The full commercial launch for the system is scheduled by 2025. No value for the order has been disclosed.
Update on Japan, May 2023
17 May 2023The two largest cement producers in Japan released their results for their 2023 financial years this week. Much like manufacturers elsewhere in the world they reported mounting sales revenues, but they also noted losses. Input prices such as coal rose in 2022 and these were passed on to consumers in the form of higher prices. However, this was insufficient to stop them making a loss.
In the case of Taiheiyo Cement, its domestic sales volumes of cement remained stable at 13.4Mt in the year to 31 March 2023. It made a loss at home in Japan but still reported a profit in its overseas businesses, despite export volumes falling by 41% year-on-year to 2.44Mt. The group also noted delays at construction sites due to a lack of workers. Recent domestic developments for Taiheiyo include an agreement in October 2022 to buy the cement business of chemicals company Denka. Outside of Japan, in China, the group suspended the production and sale of cement from its Jiangnan-Onoda Cement subsidiary in February 2023 citing a 'tougher competitive environment,' although it justified this decision as part of its strategy to refocus on Southeast Asia. Then, in late April 2023, the company was forced to stop its proposed acquisition of the Tehachapi cement plant in the US due to an inability to obtain regulatory approval.
Sumitomo Osaka reported a similar situation, with cement sales volumes also down year-on-year. Again, cement price increases were unable to catch coal prices made worse by negative currency exchange effects. Having got the bad news out of the way, it then it took the opportunity to outline its medium term strategy to 2035. It said that becoming carbon neutral was the key to this. In its 2022 financial year cement accounted for around 70% of total sales. However, it is now aiming to reduce this to 65% by 2025 and 50% by 2035. If this sounds familiar this is because it is similar to what Holcim is doing with its growing light building materials division and its diversification away from the heavy building materials trio of cement, concrete and aggregates. Sumitomo Osaka plans to invest over US$3.5bn towards this goal by developing its presence in the semiconductors sector, building its business in Australia and starting new ventures in decarbonisation.
Of the other cement producers, Tokuyama Corporation said in late April 2023 that it was considering suspending operation of one of the three kilns at its 4.54Mt/yr Nanyo cement plant as part of measures to strengthen profitability. It reported a growing loss for the current financial year that it blamed on raw material and fuel costs. Mitsubishi Materials and Ube Industries formed their merged cement businesses in April 2022 known as Mitsubishi UBE Cement Corporation. Ube said, as part of its latest financial results, that, despite a gradual decrease in the domestic market, cement sales had remained stable but that the business was “heavily affected” by rising energy prices such as coal. It added that demand for cement and concrete remain strong in its overseas market in North America.

The Japanese cement market peaked in the 1990s. Domestic sales of cement in Japan have declined over the last decade, as can be seen in Graph 1 above, but at a slower rate. Exports rose to a peak of just under 12Mt in 2017 but have slipped a little since then. Data from the Japan Cement Association placed production at 53.2Mt in 2022 compared to 61.7Mt in 2013. This trend explains the move by the cement producers towards decarbonisation, offshoring, diversification and consolidation. The bump in fuel prices over the past year may have accelerated this process, as examples such as Taiheiyo Cement’s takeover of Denka and Sumitomo Osaka’s new business strategy suggest. The race continues to keep cement production profitable in a changing business environment.
India: Sagar Cements says that its subsidiary Andhra Cements will relaunch the clinker line at its Durga cement plant in Andhra Pradesh before July 2023. The Hindu BusinessLine newspaper has reported that the producer previously relaunched grinding operations at the plant in April 2023.
Sagar Cements plans to invest a further US$56.8m in Andhra Cements’ Durga cement plant to increase its installed cement capacity by 67% to 3Mt/yr and its clinker capacity by 39% to 2.3Mt/yr before 2025.
Flender enlarges Voerde production plant
17 May 2023Germany: Flender has officially completed construction work on an expansion at its site in Voerde with the opening of its new logistics and storage hall for the assembly of large gear units. The hall has been built on an open area on the company's premises covering almost 8000m2. The new building is part of the drive manufacturer’s investments to be able to handle the expected growth in the global wind energy business and to drive the energy transition in Europe. In addition to large components for wind power gearboxes, the logistics hall will also serve its industrial business. The company has also leased another 10,000m2 hall, directly next door to its Voerde unit, to further support its logistics.
Flender’s chief executive officer Andreas Evertz said "With the new storage areas, we are making our logistics processes sustainable and thus reducing a considerable part of the previous transport routes and the associated CO2 emissions. Components that were previously stored elsewhere can now be stored centrally and made available for assembly more quickly with optimised transport routes.”
Flender’s Voerde plant is the company’s largest in Germany with an area of 276,000m2. It employs 1500 people.
Mexico: Cemex's waste management subsidiary Regenera has signed a deal with the municipal council of Huajuapan de León to receive the latter's sorted non-recyclable municipal solid waste (MSW). Under the deal, Regenera will receive up to 6000t/yr of MSW, which it will supply to Cemex's Tepeaca cement plant in Puebla.
France: Hoffmann Green Cement Technologies has commissioned its H2 plant, a 1000t/day clinker-free cement plant, adjacent to its existing H1 clinker-free cement plant in Bournezeau, Pays de la Loire. L'Usine Nouvelle News has reported that the new plant took 24 months to build and cost Euro22m. The main part of the plant consists of a 70m tower, where activated clay, ground granulated blast furnace slag (GGBFS) and gypsum are mixed to produce the cement. It is installed with solar panels capable of supplying 50% of its energy consumption. The producer says that its clinker-free cement has over 90% lower CO2 emissions than cement produced with ordinary Portland cement (OPC). It aims to sell 24,000t of the product throughout 2023.
