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 NO_x 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.

The 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.

Germany: 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.

India: Ambuja Cements has placed orders with equipment suppliers for an 8Mt/yr clinker capacity expansion across two of its cement plants. The plants in question are the 2.9Mt/yr Bhatapara cement plant in Chhattisgarh and the 4.5Mt/yr Maratha cement plant in Maharashtra. Ambuja Cements will also build 42MW-worth of waste heat recovery (WHR) power capacity. The new cement capacity will be able to operate on renewable energy and use 50% alternative fuel (AF). As such, upon completion of the project, the plants will together produce 14Mt/yr of Ambuja Cements' reduced-CO₂ Blended Green Cement. The producer will fund the work through internal accruals, and expects to complete it in May 2025.

CEO Ajay Kapur said "These brownfield expansion projects are part of our strategy to double our production capacity over the next five years from the current capacity of 67.5Mt/yr. Our ongoing investments in capacity expansion and sustainability will enable us to achieve our long-term objectives, as we remain committed to delivering sustainable growth and value to our stakeholders."

Eagle Materials announced this week that it had completed the acquisition of Martin Marietta’s cement import business in the north of California. A key part of the deal includes the sale of a cement terminal at Stockton. No value for the transaction has been disclosed.

The agreement prompts discussion for two immediate reasons. Firstly, it continues the enlargement of Eagle Materials’ cement business with its second terminal in California. The company operates its cement business in a band running almost right across the US. It runs seven cement plants in seven different states and jointly operates, with Heidelberg Materials, a plant in Texas too. It also runs a network of 25 cement terminals, including the new acquisition, stretching from California in the west to Pennsylvania in the east.

Eagle Materials’ focus on the cement sector also harks back to its previous plans to separate its various businesses. In 2019 it approved a plan to split its heavy materials and light materials businesses into two publicly-traded entities. The decision was made in response to pressure by shareholder Sachem Head Capital Management to make the company, in its view, more valuable. A strategic portfolio review followed but the planned separation was subsequently delayed due to the Covid-19 pandemic and poor market conditions, amongst other reasons. The board of the company then cancelled the proposed separation in 2021 citing the financial benefits of a diversified business, opportunities for strategic growth and the divestment of its oil and gas proppants business.

The other talking point is that the Eagle Materials transaction follows a positive response by the Federal Trade Commission (FTC) in response to the abandonment of CalPortland’s attempt to buy the Tehachapi cement plant in southern California and two related terminals from Martin Marietta. CalPortland’s parent company Taiheiyo Cement said in late April 2023 that it had terminated the acquisition agreement originally announced in mid-2022 due to its inability to obtain approval from the FTC in a timely manner. Whilst the FTC did not say if it had directly tried to block the proposed deal it did say, “The abandonment is a victory for consumers and preserves competition for a key component of Southern California’s construction and infrastructure industries.”

The FTC argued that the transaction would have reduced the number of cement suppliers in Southern California from five to four, further concentrating an already concentrated market, and was “presumptively illegal.” It noted that the Tehachapi plant was only about 20km away from CalPortland’s Mojave cement plant. It went on to say that, if the deal had gone ahead, CalPortland was poised to own half of the cement plants serving the Southern California market. It added that it would have been well-placed to raise its prices and that, “the transaction would have also increased the likelihood for coordinated action between the remaining competitors in this concentrated market.”

The de-facto block by the FTC of the Tehachapi sale now opens up the question of who Martin Marietta might try to sell it to next. Cemex, Mitsubishi Cement and National Cement (Vicat) are the obvious contenders given that they each also run integrated plants in the state. Of course another company, especially one with some form of existing distribution network, may express interest. Given its enlarged presence in Northern California, Eagle Materials springs to mind. Other potential buyers are, of course, available.
