Heidelberg Materials increases sales as profit drops in 2022
23 February 2023Germany: Heidelberg Materials' sales increased by 13% year-on-year to Euro21.1bn in 2022 from Euro18.7bn in 2021. This was despite a 6.1% drop in cement and clinker volumes, to 119Mt from 127Mt. Heidelberg Materials' cement and clinker volumes fell by 10% in Western and Southern Europe, by 7.8% in Northern and Eastern Europe-Central Asia, by 14% in North America, by 1.3% in Africa-Eastern Mediterranean Basin and by under 1% in Asia-Pacific. The group's materials costs rose by 23% to Euro21.4bn from Euro18.8bn. Meanwhile, its profit dropped by 9.4% to Euro1.72bn from Euro1.9bn.
Chief executive officer Dominik von Achten said "It’s evident that we can only be profitable in the long term by shaping our future as a company in a climate-compatible way, further reducing the footprint of our products and closing material loops. We are making good strides in all areas. Compared with the previous year, we were able to reduce our specific net CO2 emissions by another 2% in 2022. Our carbon capture, utilisation and storage projects launched worldwide are progressing favourably. At our CCS project in Brevik, Norway, we are well on track with the construction of the world's first CO2 capture plant in our industry, and we look forward to commissioning in 2024." Von Achten continued "We have made a good start to 2023. The fourth quarter showed that we have laid a good foundation for the development in this year. Volatility on energy and raw material markets remains high, but the current easing in energy prices is giving us some breathing room. On the demand side, government infrastructure plans should compensate for the decline in private housing construction. We are optimistic about the further course of the year.”
Leilac signs deal with Heirloom on direct air capture of CO2
22 February 2023US: Leilac has signed a memorandum of understanding (MOU) with US-based Heirloom to use Leilac’s kiln technology in Heirloom’s direct air capture (DAC) process. The MOU outlines the key terms for a licence and collaboration agreement.
Daniel Rennie, the chief executive officer of Leilac, said “Leilac is delighted to be partnering with Heirloom. Our partnership will apply Leilac’s core technology for cement and lime decarbonisation to address the global challenge of excess atmospheric CO2.” He added “Heirloom uses low-cost and abundant limestone, which Leilac’s technology is specifically designed for. Both technologies are modular, easily scalable and can be renewably powered.”
Heirloom is developing a method of using limestone to remove atmospheric CO2 in a DAC process. The proposed DAC method using both Leilac and Heirloom technology will heat limestone in a Leilac kiln to release CO2 that can then be captured and sequestered. The lime that the kiln produces will then be reformed back into limestone directly capturing CO2 from the atmosphere in an accelerated process. This limestone will then be feed back into the kiln restarting the process. The partners also suggest powering the kiln from renewable electricity sources to further increase the net reduction of CO2 emissions from the process. No cost for the combined process or who would pay for it has been revealed so far.
Leilac is a subsidiary of Australia-based Calix that has been testing its indirectly heated calcination technology with the cement and lime industry since the mid-2010s. An industrial scale application of the process at Heidelberg Material’s Hanover cement plant in Germany is expected to be ready to start testing by the end of 2023. Additional projects have been announced in Australia with Adbri and Boral.

Prometheus Materials’ product is poised to change the future of construction, converting one of the most carbon-polluting industries to a low-carbon – and one day net-zero carbon – reality.”
Hoffmann Green Cement Technologies wins three-year residential projects supply contract
21 February 2023France: Hoffmann Green Cement Technologies has won a contract to supply property developer Belin Promotion with its clinker-free cement for use in its residential property development projects up until March 2026. Dow Jones Institutional News has reported that the deal includes minimum volume commitments.
Dalmia Cement (Bharat) deploys gas-fuelled truck fleet
20 February 2023India: Dalmia Cement (Bharat) has successfully launched its new fleet of 35 liquefied natural gas (LNG)-fuelled trucks from its Murli cement plant in Maharashtra. The trucks are of two types, covering ranges of 50 - 600km, and will transport bagged cement and bulk raw materials. They have 28% lower CO2 emissions than conventional diesel-powered trucks, and are thus able to eliminate 840t/yr of CO2 emissions, while also reducing emissions of nitrous oxides (NOx) by 59% and particulates by 91%, and eliminating emissions of sulphur oxides (SOx).
Dalmia Cement (Bharat) says that its next move will be to launch a second fleet of 25 trucks from its Ariyalapur cement plant in Tamil Nadu. By April 2024, it plans to convert 10% of its 3000 truck-strong fleet to LNG fuel.
A spokesperson for the company said “Dalmia Cement has been following the business philosophy of Clean & Green is Profitable and Sustainable. Our overall CO2 emissions have come down from 670kg/t to 467kg/t – one of the lowest globally – and we are focusing on realising our carbon negative goal by 2040. We are delighted to partner with GreenLine Logistics for further reduction of our Scope 3 greenhouse gas emissions.”
South/Central America: Holcim Latinoamérica says that it expects to use 18% renewable power across its operations in February 2023, compared to 8% throughout 2022. The regional unit of Holcim says that it will increase its share of renewable power to 25% by the end of 2023. It is committed to a target of 60% renewables by 2030. Holcim Latinoamérica's operations span Argentina, Colombia, Costa Rica, Ecuador, El Salvador, Nicaragua and Mexico.
Earlier in February 2023, Holcim Nicaragua commenced construction of a 3.38MW solar power plant in Nagarote, León Department. The producer said that the solar power plant's contribution to the national grid will cover 40% of its consumption in its cement operations there.
Holcim's Latin America regional head Oliver Osswald said “Our world is in constant change from population growth, urbanisation and the climate challenge. That is why, at Holcim, we are determined to put our best foot forward to accelerate low carbon circular construction."
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.
RHI Magnesita invests in MCi Carbon on decarbonisation deal
15 February 2023Austria: RHI Magnesita has invested in Australia-based MCi Carbon as part of a long-term strategic cooperation agreement to research and develop technologies to decarbonise the production of refractories. MCi Carbon sells a mineral carbonation process that creates a range of low-carbon embodied materials, including calcium and magnesium carbonate by carbonating minerals in by-products of industrial processes. RHI Magnesita intends to use this process to reduce its Scope 1 emissions from mineral processing during its refractory production process.
Stefan Borgas, the chief executive officer of RHI Magnesita, said "This partnership could become a breakthrough towards decarbonising the industry. It fits seamlessly with RHI Magnesita's ambitious sustainability strategy." He added "We still have a long way to go but our early-stage investment and the clear intention of a long-term collaboration make this day so memorable. Together with the like-minded team from MCi we will pave the way for a greener industry."
So far, both companies have worked together on CO2 mitigation studies, mineral carbonisation feedstock assessments and techno-economic analyses at RHI Magnesita's sites around the world. In a next step, the companies' joint efforts will focus on industrial scale-up, expected to start in 2024 with the set-up of a demonstration plant by MCi at Newcastle in Australia, supported by the Australian government.
Titan Cement buys share in Aegean Perlites
14 February 2023Greece: Titan Cement has acquired a share in Aegean Perlites. The company operates perlite and pozzolan quarries on the island of Yali. It also has access to port facilities. Titan Group says it is making the investment to gain direct access to pozzolan reserves to increase its volume of pozzolan-based cementitious products with a lower clinker factor. The deal is connected to Titan’s target to reduce its CO2 emissions by 35% by 2030, compared to 1990 levels, and increase the share of green products in its portfolio to over 50%.
Yanni Paniaras, the Group Executive Director Europe of Titan, said “We are pleased to partner with the Govdelas family as joint shareholders in Aegean Perlites, building on our excellent long-term collaboration and aiming to grow our business, maximising the high potential of the Yali pozzolans.”
Belgium: Cembureau, the European cement association, has warned against a proposed 2041 phase-out date for industrial CO2 in the Commission draft Delegated Act on renewable fuels of non-biological origin (RFNBOs). The European Commission’s (EC) draft Delegated Act on the greenhouse gas saving criteria for RFNBOs sets the rules under which such fuels can qualify as sustainable. The European Commission considers that CO2 from industrial sources should not be allowed for the production of synthetic fuels as of 2041, as this would go against the objective of carbon neutrality by 2050.
Koen Coppenholle, the chief executive officer of Cembureau, said “By proposing an arbitrary deadline on the use of industrial CO2, the EC severely restricts the deployment of carbon capture and utilisation (CCU) in the cement sector.” He continued “We regret that this phase-out date was established without a thorough impact assessment. This risks negatively impacting several on-going carbon capture projects in the European Union (EU), at a time of a global race for green investments.” Coppenholle also called for a “real, thorough debate on CO2 utilisation” to ensure that EU policies support CCU and the deployment of CO2 transport infrastructure and storage.
The association is objecting against this proposal because in its view: manufacturing synthetic fuels using industrial CO2 make a “decisive” contribution to climate mitigation in the short to medium term; no impact assessment has been presented by the EC; the delegated act threatens the viability of existing CCU projects in the cement sector, which require a payback time of 30 - 35 years; and the Delegated Act does not recognise the reality of industrial installations like cement plants, which are faced with unavoidable CO2 emissions, and may not have access to CO2 geological storage sites.
The Delegated Act will be passed to the European Parliament and Council for further scrutiny until April 2023 whereupon they will either accept to reject the proposals. The scrutiny period can be extended to June 2023 at the request of either body.
