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.
Minister calls for cancellation of new cement plant in Hub
15 February 2023Pakistan: Balochistan's local government minister has called for the cancellation of the allotment of a large area of land to a cement plant in Hub, adding that he would take the matter to court. Mohammad Saleh Bhootani said the Mines and Minerals Development Department had allotted 18,200 hectares of land that he says belonged to the people of Hub and Lasbela districts.
The allotted land comprises mountains, agriculture lands, hundreds of villages, farms and graveyards, he said, arguing that there was no justification for allotting such a vast area to a cement plant. Bhootani warned locals that fences would soon be erected around the site, forcing those that live there out of their homes. He urged Chief Minister Abdul Qudoos Bizenjo to “show mercy on the poor people of the area and cancel the allotment.” The minister said that if the allotment was not cancelled, he and the people of the area would take legal action.
The parliamentary leader of the Balochistan National Party-Mengal, Naseer Ahmed Shahwani, condemned the allotment and demanded the government withdraw its decision. 'If such practices continue, what will be the future of Balochistan?' he wondered.
Century Peak Cement starts distribution in Visayas
14 February 2023Philippines: Century Peak Cement Manufacturing has started distributed its cement products to the Visayas region. Its blended hydraulic and ordinary Portland cement product received quality standard certification from the Department of Trade and Industry in January 2023.
Century Peak Cement operates a plant at Pinamungajan in Cebu with associated limestone reserves. The unit has its own pier.
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.

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.
JK Lakshmi Cement awards solar power plant contract to Amplus Solar
08 February 2023India: Amplus Solar has secured a contract with JK Lakshmi Cement for construction of a 56MW solar power plant at the producer’s 1.7Mt/yr Durg cement plant in Chhattisgarh. The producer expects to eliminate 73,000t/yr of CO2 emissions as a result.
JK Lakshmi Cement’s president Arun Shukla said "We support the country's vision to achieve net zero emissions by 2070. We have taken multiple steps to reduce both direct and indirect carbon emissions. Last month, for the first time in India, we deployed liquefied natural gas (LNG) trucks to transport raw material. Now, with the switch to solar energy at our Durg plant, nearly 80% of the plant’s energy requirements will be met renewably.”
Amplus Energy previously partnered with UltraTech Cement for a 50MW solar installation at one of its cement plants in 2019.
OYAK Çimento/Taiwan Cement Company joint venture restarts one cement plant after Türkiye earthquake
08 February 2023Türkiye: OYAK Çimento and Taiwan Cement Company (TCC)s’ joint venture says that it has successfully restarted one of its Turkish cement plants following an earthquake on 6 February. The Netherlands-based joint venture said that two further plants remained at a standstill due to a regional power outage.
Two major tremors, of magnitudes 7.8 and 7.5 on the Richter scale, originated near Gaziantep in Türkiye’s Southeastern Anatolia Region. TCC immediately activated its Employee Care Plan to assist and arrange aid for employees and their families, dispatching 100 emergency kits by courier.
On 8 February 2023, rescuers had reported that 9460 people had died in the catastrophe, 6960 in Türkiye and 2500 in Syria.
Heidelberg Materials North America to study options for CO2 sequestration in Indiana
08 February 2023US: The Department of Energy’s (DOE) Carbon Storage Assurance Facility Enterprise (CarbonSAFE) initiative has awarded funding of US$8.9m to Heidelberg Materials North America to study the subsurface geology for suitability for the storage of carbon dioxide at the Mitchell integrated cement plant in Indiana. The proposed project will geologically characterise several prospective reservoirs under the Mitchell plant for storage of more than 50Mt of CO2 over a 30-year timeframe.
The award, which is managed by the National Energy Technology Laboratory, will be issued to the Illinois State Geological Survey at the University of Illinois (ISGS) as the prime contractor, with the company acting as a technical and industrial partner. Heidelberg Materials is contributing about US$1.5m in funding while ISGS will be contributing approximately US$0.6m for a project total of US$11.1m. The funding was part of a DOE initiative that generated nearly US$125m in funding for 10 projects to characterise suitability for carbon storage across the US.
Heidelberg Materials’ Mitchell cement plant is being upgraded with a new production line. Full production on the new line is anticipated to start in early 2023.

Update on construction and demolition waste, February 2023
01 February 2023Cemex launched a new waste management division called Regenera this week. Cemex describes Regenera as a “business that provides circularity solutions, including reception, management, recycling, and coprocessing of waste.” The Mexico-based company has a long and leading history with sourcing and using alternative fuels in the cement sector and the new organisation looks set to utilise this experience. What is notable though is how the business is targeting three waste streams: municipal and industrial; industrial by-products; and construction, demolition and excavation waste (CDEW). Bringing the three waste streams together in this way appears to be novel for the heavy building materials sector, particularly the inclusion of CDEW, which we will explore further here.
CDEW is split into fractions, just like the municipal and solid waste streams that end up as alternative fuels at cement plants, but the biggest fractions are generally concrete, followed by bricks. The recycled concrete is then typically used as an aggregate, either in new concrete production or in areas like road construction and earthworks. The use of recycled aggregates (RA) made from CDEW goes back to at least the 1930s in its current form although ‘reusing’ materials from structures such as castles and churches goes back far further. Recycling and reusing CDEW gained a boost in 2020 when the European Union (EU) set a 70% recovery target. However, within the EU the CDEW recycling rates vary considerably and that 2020 target includes the use of CDEW in backfill applications.
In its launch statement for Regenera, Cemex noted that it operates a dock in Paris, where it receives a variety of materials, including construction debris, excavated material and inert soil. These materials are sorted, processed and then transformed into recycled aggregates or organic material used to restore quarries. Cemex then promptly followed up the official launch of Regenera on 30 January 2023 with the acquisition of a majority stake in Shtang Recycle, an Israel-based CDEW recycling company. It added that Shtang Recycle is preparing to build a recycling plant with a production capacity of 0.6Mt/yr of CDEW waste materials. The output from the plant will be used as raw materials for aggregate production.
The focus on CDEW recycling was flagged up at Cemex’s investor event in November 2022. It said that it was targeting a recycling rate of 14Mt/yr of construction and demolition waste by 2030. Other managed waste stream goals included doubling the amount of municipal and industrial waste it manages, to achieve a 50% to fossil fuel substitution rate, and increasing its usage of alternative raw materials and by-products by 30%, thereby eliminating 13Mt/yr of extracted materials.
Cemex is not alone in targeting the CDEW waste sector. Holcim’s recent work in the area goes back to at least 2016 when a recycling unit near its Retznei cement plant in Austria started processing 130,000t/yr of CDEW. It announced in December 2022 that it was setting up a similar recycling centre, also in Austria, at its Mannersdorf cement plant. In October 2022 Holcim acquired Wiltshire Heavy Building Materials in the UK. This company recycles 150,000t/yr of construction and demolition waste into aggregates and concrete. Holcim linked the acquisition to its Strategy 25 target of recycling 10Mt/yr of construction and demolition waste by 2025.
Activity by other cement companies includes the commissioning of a construction waste recycling plant at Gennevilliers in France by CRH-subsidiary Eqiom in April 2022. It was aiming for a target of 50,000t in 2022. In November 2022 Heidelberg Materials agreed to acquire RWG Holding based in Berlin, Germany. Then, in December 2022, it announced a deal to buy Mick George Group in the UK. Both proposed acquisitions are subject to competition authority approval. Heidelberg Materials’ current target is to offer circular alternatives for half of its concrete products by 2030.
The moves by the bigger cement companies into the CDEW sector follow sustainable thinking and the waste hierarchy. Yet the big prize here is to gain a route to dispose of some of their CO2 emissions through recarbonation and this has been flagged up in several net-zero roadmaps for the cement sector such as those by Cembureau and the Global Cement and Concrete Association (GCCA). Holcim has been involved in the FastCarb project in France, running a pilot at its Val d’Azergues cement plant in 2021. Heidelberg Materials has been testing its own process with so-called recycled concrete paste. The development now appears to be that utilising CDEW has entered the sustainability strategies for some of the big cement-concrete-aggregate producers, targets have been set and acquisitions are happening.
