Thailand: Switzerland-based Maerz has commissioned a new 150t/day lime kiln at Bangkok CaO’s plant at Saraburi. The kiln is the third Parallel Flow Regenerative (PFR) unit that Maerz has supplied to the site following previous installations in 1996 and 2008. All the kilns at the plant use waste oil as a fuel.

Congratulations to Lafarge France for launching the first calcined clay cement unit in Europe. The subsidiary of Holcim says that the unit, based at the integrated Saint-Pierre-la-Cour cement plant, is the first of its kind on the continent. It is using the company’s proprietary proximA Tech technology and will produce up to 500,000t/yr of cement in its ECOPlanet range. The operation is also powered with biomass alternative fuels and uses a waste recovery system to further drive down overall CO₂ emissions. Once production ramps-up the producer expects that 30% of cement from the Saint-Pierre-la-Cour plant will be from the ECOPlanet range by 2024.

The investment at Saint-Pierre-la-Cour was Euro40m. Holcim is also producing calcined clay cement at its La Malle plant in France. It received an investment of Euro6m in 2022 to produce low-carbon cements. Together, both plants are aiming to produce over 2Mt/yr of calcined clay cement by 2024. As is usual for these kinds of projects, the French government partly funded the clay calcination unit at Saint-Pierre-la-Cour as part of the ‘France Relance’ scheme investing in large-scale decarbonisation and energy efficiency initiatives.

Calcined clay cements in Europe aren’t exactly new, but Holcim’s new unit in France does appear to be the first full-scale line located at a cement plant. Research by OneStone Consulting, for example, reckons that the first flash activated clay unit expressly set up to supply the cement sector was commissioned in 1995 in Toulouse, France. More recently, Hoffmann Green Cement inaugurated its 50,000t/yr pilot plant at Bournezeau in France in 2018. This site produces cements made from flash calcined clay and blast furnace slag, although it is unclear how demand for the different products varies. A new 0.25Mt/yr plant in the Vendée department was scheduled for commissioning in the second half of 2022. Another 0.25Mt/yr plant in Dunkirk is expected to be commissioned in the second half of 2024.

Cementir Group launched its calcined clay cement product FUTURECEM in Denmark in 2021 with production via a pilot plant. It then extended this to the Benelux and French cement markets in 2022. As part of its industrial plan for 2021 - 2023 it was planning to build a clay calcination unit to support the growth of FutureCem. FLSmidth revealed in June 2021 that it had won a contract to build a 400t/day clay calcination unit for Vicat’s Xeuilley integrated cement plant. The deal was worth around Euro27m and commissioning is scheduled for 2023.

Firstly, it is interesting to see a focus on France for some of the projects above. The presence of Lafarge’s technical centre in Lyon may explain the interest for that company. However, Hoffmann Green Cement and Vicat are also active in the field. It is worth noting that France also holds a busy secondary cementitious material market with standalone operators including Ecocem, Cem’In’Eu and Hoffmann Green Cement. Secondly, despite the early start, clay calcination for cement is currently more active outside of Europe. In Africa, for example, there is at least one live full production line and a number of other projects on the way. Various other pilots and projects are also happening elsewhere around the world, often in conjunction with the limestone calcined clay cement (LC3) initiative. Where calcined clay cement production in Europe goes from here is uncertain at present as it is one solution among many for lower carbon cement products in the future. Yet, the projects that have made it so far to the commercial scale will be watched closely by the companies that have invested in them - and their competitors.

Bangladesh: Aman Cement has held a ceremony to launch a second 5000t/day vertical roller mill at its Unit 2 Siragonj grinding plant in Narayangonj. The plant now has a total production capacity of 10,000t/day, according to the Daily Star newspaper. Germany-based Loesche previously supplied the first mill for the plant.

France: Holcim has opened what it says is the first calcined clay unit in Europe at its Saint-Pierre-la-Cour cement plant. The production line uses the company’s proximA Tech process to produce up to 0.5Mt/yr of products in the ECOPlanet range. The unit is powered with 100% biomass-based alternative fuels and uses waste heat recovery systems to make production “nearly carbon free and ultra-efficient.”

Miljan Gutovic, Region Head Europe for Holcim, said “The opening of the first calcined clay cement production line in Europe is another milestone in our mission to decarbonise building. We are scaling up our calcined clay cements across all regions by 2025, to advance our ECOPlanet range of low-carbon cement, making low-carbon construction possible at scale.”

The upgrade project received financial support from the French government, as part of the ‘France Relance’ scheme to invest in large-scale decarbonisation and energy efficiency initiatives.

Australia: Boral recorded sales of US$1.17bn during the first half of its 2023 financial year, up by 12% year-on-year from US$1.05bn during the first half of its 2022 financial year. Cement sales were US$128m, 11% of group sales. The producer’s net profit fell by 91% year-on-year to US$62.5m from US$715m.

During the half, Boral’s subsidiary Geelong Cement commissioned a new 0.8Mt/yr grinding unit at its 0.6Mt/yr Waurn Ponds grinding plant in Victoria. The group also upgraded the chlorine bypass system at its Berrima cement plant in New South Wales to support increased alternative fuel (AF) co-processing. Throughout 2022, Boral substituted 15% AF into its fuel mix.

Senegal: China-based Sinoma CBMI Construction has commissioned a new production line at Ciments du Sahel’s Kirene plant near Dakar. The new 6000t/day line is intended to replace the plant’s existing third production line. Ciments du Sahel signed a contract with Sinoma CBMI to upgrade the plant in 2020.

Japan: Mitsubishi Heavy Industries (MHI) has won an Award for Excellence at the 41st Nikkei Excellent Products and Services Awards for its carbon capture system. It was among eight industrial products to win the award for the year. The panel of judges selected MHI's system for its compact and versatile module configuration, which shortens installation and transport times.

MHI's model has been in industrial operation since June 2022, when MHI inaugurated its first system at Taihei Dengyo Kaisha's Seifu Shinto biomass power plant. The technology is now in operation or under implementation at cement plants in Japan and overseas. Most recently, MHI secured a carbon capture contract with a UK cement plant, Hanson's Padeswood plant, in mid-December 2022.

Finland: Finnsementti and energy provider St1 have selected Norway-based Aker Carbon Capture to carry out a pre-engineering study for a planned carbon capture system at the cement producer's Lappeenranta cement plant in South Karelia. Dow Jones Institutional News has reported that Aker Carbon Capture offers a 40,000t/yr carbon capture system, capable of producing 25,000t/yr of methanol for use as transport fuel. The project is scheduled to deliver commercial synthetic methanol by 2026.

The Lappeenranta cement plant carbon capture project recently received Euro35.4m in additional funding from the Finnish government, subject to European Commission approval.

Germany: Hazemag has successfully completed its construction of a Centre Sizer 1025 crusher and a HAF25142 apron feeder. Hazemag will now despatch the equipment to Florida, US, where a ‘major aggregate and cement producer’ will integrate them in its operations.

Hazemag said “From the project’s inception, this producer focused on key partners that could deliver proven, reliable solutions - we are happy to be one of them.”

Cementos Artigas inaugurated an upgrade to its integrated Minas plant this week. The joint-venture between Spain-based Cementos Molins and Brazil-based Votorantim Cimentos has been working on the US$40m project since mid-2020. The main plan is to combine the functions of the integrated Minas plant in Lavalleja and the company’s cement grinding plant at Sayago in Montevideo at one site. Key parts of the upgrade included the installation of a new vertical grinding mill, a cellular silo and a bulk cement despatching centre. The Uruguayan president Luis Lacalle turned up for the opening ceremony.

The cement sector in the country is modest compared to those in its much larger neighbours, Argentina and Brazil. It only has four integrated plants with a total production capacity of around 1.4Mt/yr compared to, say, Brazil’s 70-odd plants with a capacity in excess of 85Mt/yr. However, a few things have been happening recently that are worth noting. Firstly, a new integrated plant operated by a new entrant opened in mid-2021. Cielo Azul Cementos y Calizas was set up by investors in Brazil with links to Uruguay. It started in ready-mixed concrete (RMX) in the early 2010s before it contracted FLSmidth in 2017 to build it a 0.6Mt/yr integrated cement plant at La Pacífica in Treinta y Tres. It has also opened an RMX plant in neighbouring Paraguay.

Votorantim Cimentos may have been irked by the opening of a new competitor in Uruguay as it blamed it for a drop in its third quarter revenue in 2022 in its Latin American region outside of Brazil. It described the dynamic in the country as ‘challenging.’ Its local business partner, Cementos Molins, was a bit more balanced in its assessment for 2021, reporting that earnings had falling slightly due to global input cost rises and that sales had fallen due to increased competition from new capacity. Whatever else happens, now that the Minas upgrade project has finished, it seems likely that Cementos Artigas’ costs have the potential to decrease.

The country’s third cement producer, Cementos del Plata, was also busy in 2022. The subsidiary of state-owned Administración Nacional de Combustibles, Alcohol y Portland (ANCAP) announced in September 2022 that is was going to seek a business partner in its business. Its reasoning was that it wants to restore competitiveness to the local cement market and reverse the ‘deficit’ economic situation of the last 20 years. By November 2022, 11 companies had been selected for the next stage of the process. Notable entrants include InterCement-subsidiary Loma Negra, Empresa Publica Productiva Cementos de Bolivia (ECEBOL), Cementos Artigas, Cielo Azul Cementos y Calizas and the Turkish Cement Manufacturers' Association (TürkÇimento). That last name is particularly interesting as it is the only organisation with an obvious link to the cement sector from outside of South America. Two China-based engineering companies are also among the contenders.

Prior to the current initiative to gain inward investment into Cementos del Plata, ANCAP has been noteworthy for union activity at its plants such as strikes in recent years. A reported attempt to privatise the Paysandú plant in 2020 was blocked by the unions, according to local press. In separate news, ANCAP concluded from an investigation in June 2022 that persons unknown had attempted to intentionally damage the kiln of its Minas plant through the introduction of foreign materials. There is no reason to connect the two stories but it does suggest that any investor into the business might want to consider a wide variety of stakeholders as part of any due diligence process.

Uruguay’s cement sector is changing as we have seen above. Cementos Artigas has completed an upgrade to one of its plants, Cielo Azul Cementos y Calizas built a new integrated plant in 2021 and Cementos del Plata is actively hunting for a partner. Just who that new investor might be has implications for the local sector. The Government of Uruguay announced in 2021 that it wanted to set up free trade agreements with China and Türkiye. Unsurprisingly, both Turkish and Chinese organisations are amongst the ones that have made it to the current selection stage.
