Senegal: The International Finance Corporation (ICF) has arranged a Euro242m finance package for SOCOCIM Industries to build a new production line at its Rufisque cement plant in Dakar Region. Euro214m of the loans will be used to decarbonise cement production at the site, including a contribution towards a larger Euro260m upgrade project. The new planned production line will have an alternative fuels substitution rate of 70%, increased energy efficiency and will reduce the plant’s CO2 emissions.
The finance package organised by the IFC comprises a Euro120m loan from the IFC's own account and Euro122m equivalent in local currency parallel loans from Société Générale Sénégal, CBAO Groupe Attijariwafa Bank, Banque Internationale Pour Le Commerce et l'Industrie du Sénégal, and Ecobank Sénégal. Société Générale Sénégal has been appointed as the administrative agent to manage the local currency financing with the other lenders.
SOCOCIM is a subsidiary of France-based Vicat. Fives revealed in early 2022 that it would supply a 6500t/day kiln line for the Rufisque plant.
Switzerland: Holcim has commissioned the world's first cement plant digital twin at one of its cement plants in Switzerland. The software models the plant and is integrated with sensors, analytics and machine learning technology. UK-based HyBird also participated in the development of the technology. Holcim expects it to help to optimise its operations. Under its Plants of Tomorrow automation strategy, it will now aim to roll out the system across all of its cement plants, beginning with those in Europe.
Holcim's global head of Plants of Tomorrow, Rozemarijn Wesby, said "Our digital twin in Switzerland is a breakthrough for the entire industry. By leveraging digital technologies like this, we are generating massive amounts of data, allowing smarter decision-making to take our operational efficiency to the next level."
Rohrdorfer commences carbon capture at Rohrdorf cement plant
22 February 2023Germany: Austria-based Rohrdorfer has started up an amine-based carbon capture system at its Rohrdorf cement plant in Bavaria. The producer plans to ultimately expand the system up to a capture capacity of 1500t/day. The inauguration follows a successful continuous trial of the technology since August 2022, excluding a regular kiln maintenance period over winter. Austria-based Andritz designed the system specifically for the Rohrdorf cement plant. It yields CO2 that is suitable for numerous applications, including in food and beverages and in intermediate products in pharmaceuticals production. The Rohrdorf cement plant also hosts a formic acid plant which uses captured CO2.
Rohrdorfer aims to achieve carbon-neutral cement production by 2038. Alongside production-related optimisations, the producer plans to realise its aim through a future expansion to the Rohrdorfer plant’s carbon capture system and the implementation of a further carbon capture upgrade at a second cement plant in Austria.
Maerz commissions lime kiln for Bangkok CaO
22 February 2023Thailand: 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.
Update on calcined clays in Europe, February 2023
15 February 2023Congratulations 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.

14 February 2023Bangladesh: 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.
Holcim opens its first calcined clay unit in Saint-Pierre-la-Cour cement plant in France
13 February 2023France: 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.

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.
