Denmark: Swisspearl Group has concluded an agreement to acquire fellow fibre cement board producer Cembrit. The Switzerland-based group said that it is creating the second-largest supplier of fibre cement products in Europe.

Denmark: GE Renewable Energy has invested in a minority stake in COBOD International. The companies said that the investment will build on their existing relationship since 2019. GE Renewable Energy chose COBOD International as the global market leader in 3D printing technology, which experienced double-digit growth in 2020.

GE Renewable Energy advanced manufacturing technology leader Matteo Bellucci said “This agreement, which will further strengthen our ability to use COBOD’s 3D printing technology and competences in the renewable energy space, is another sign of our commitment to help drive the energy transition by investing in technology that promotes a more sustainable, circular design strategy and helps to create local jobs.” He continued “Since we started cooperating with COBOD, the company has continued to improve their technical competence and innovative solutions, reinforcing the benefits of solidifying the relationship between our companies.”

Italy: Cementir’s revenue rose by 21% year-on-year to Euro362m in the first quarter of 2022 from Euro301m in the same period in 2021. It attributed this to higher prices linked to the increase in the costs of fuels, electricity, raw materials, transport and services. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) grew by 26% to Euro60.7m from Euro48.1m. Grey, white and clinker sales volumes increased by 1.8% to 2.4Mt and ready-mixed concrete sales volume remained stable at 1.13Mm³. Cement sales volumes grew in Belgium, Denmark and the US but fell in Turkey. Concrete sales volumes grew in Belgium and Norway but fell in Turkey, Sweden and Denmark.

Denmark: FLSmidth’s sales were US$670m in the first quarter of 2022, up by 27% year-on-year. Its earnings before interest, taxation and amortisation (EBITA) rose by 59% to US$43m. The supplier’s cement business recorded a sales increase of 10%. This contributed to a continuation in the ‘positive trend’ in earnings from the end of 2021, along with improvements from executed reshaping activities. The business made a property sale worth US$3.27m. In light of the results for the quarter, the company announced that it has maintained its guidance of US$2.49 – 2.71bn consolidated sales and US$783 – 855m in cement business sales in 2022.

Chief executive officer Mikko Keto said “The first quarter of 2022 saw a strong momentum in order intake driven by both mining and cement.” Keto expanded “Our cement business has continued its positive development on improving profitability.”

Regarding the on-going Russian invasion of Ukraine, he said “Our key priority in this challenging time of war has been on the safety and well-being of our employees. We closely follow this tragic situation to ensure we take the right responsible decisions from a humanitarian, legal, and financial point of view.”

India: Dalmia Cement (Bharat) has signed a memorandum of understanding (MOU) with Denmark-based FLSmidth to collaborate in the research and development of sustainable solutions for cement manufacturing. The agreement has been arranged under the ‘Green Strategic Partnership’ initiatives between Denmark and India that cover energy and climate change.

Under the MOU both companies will cooperate on a range of areas such as substituting conventional energy supplies with renewable sources and working towards CO₂ emissions abatement. Both companies have committed to contributing research and development towards eventually building an industrial scale production plant where the new concepts can be further tested.

Mahendra Singhi, the managing director and chief executive officer of Dalmia Cement (Bharat) said, “In alignment with the ambitious net zero vision of our Prime Minister Narendra Modiji and given the strength and stature of our respective organisations, this association will provide futuristic solutions to the cement and concrete industry to emerge clean and green.” He added that India and Dalmia Cement in particular were keen to develop a roadmap for the implementation of Industry 4.0 with totally decarbonised cement plants and a ‘lighthouse’ cement plant.

Denmark: FLSmidth has formed a partnership called ECoClay to develop and commercialise the technology needed to electrify the calcination of clay used in cement production. The partners include the Danish Technological Institute, US-based industrial heating specialist Rondo Energy, France-based Vicat, Colombia-based Cementos Argos and the Technical University of Denmark. The project is partly funded by the Energy Technology Development and Demonstration Program (EUDP) under the Danish Energy Agency.

The use of calcined clay in cement production allows cement producers to replace up to 30% of limestone-based clinker, resulting in up to 40% lower CO₂/t in cement produced. By electrifying the process, ideally powered by renewable sources, the ECoClay partnership expects to further reduce emissions by 10% at more uniform conditions that allow processing of a broader range of raw clays.

Based on the shared research and tests on high-temperature electric heat generation, storage solutions and renewable grid integration, the ECoClay partnership will build a pilot plant at FLSmidth’s research and development centre in Denmark. The consortium will seek to demonstrate how the ECoClay process is superior to the conventional combustion processes, has a smaller physical footprint on site and significantly lower emissions of air pollutants. According to the project plan, the ECoClay partners expect to be able to commence construction of the first full-scale electric clay calcination installation by the end of 2025.

Ghana: Denmark-based Investeringsfonden for Udviklingslande (IFU) and Norway-based Norfund have invested US$27.9m in CBI Ghana. The funding will support the cement producer’s upgrade of a clay calcination unit at its 0.6Mt/yr Tema grinding plant in Accra. Denmark-based FLSmidth is supplying the equipment for the project.

Ghana: FLSmidth has secured a contract for the supply of a clay calcination plant at CBI Ghana's 0.6Mt/yr Tema grinding plant in Accra. The supplier says that it will also install a complete grinding station to more than double the plant's production capacity. FLSmidth says that the entire project will reduce the Tema facility's CO₂ footprint by 20%. When commissioned, the new clay calcination plant will be the largest in the world, according to the supplier.

CBI Ghana chief executive officer Frédéric Albrecht said “Ghana is the perfect location for using clay as an environmentally friendly alternative to clinker. West Africa is traditionally a clinker and cement-importing region due to the lack of suitable limestone reserves. Developing countries with their young populations and a growing need for infrastructure and housing represent the future in cement consumption. Calcined clay cements are the most sustainable alternative to traditional clinker-based cement."

From the Nordics to the Mediterranean, European countries lead the field in reduced-clinker cement production using supplementary cementitious materials (SCMs). While consumers, faced with ever-greater choice, continue to opt for sustainability, projects to improve existing SCMs and develop new ones have won government backing and have become a matter of serious investment for other heavy industries beside cement. European cement producers’ decisions are steering the course to a world beyond CEM I. Yet, even in Europe, great untapped potential remains.

Companies generated a good deal of marketing buzz around their latest reduced-CO₂ cement ranges in 2021 and the first quarter of 2022: Buzzi Unicem’s CGreen in Germany and Italy, Holcim’s EcoPlanet in six markets from Romania to Spain, Cementir Holding’s Futurecem in Denmark and Benelux, and Cemex’s Vertua in Spain and several other countries. All boast reduced clinker factors through the use of alternative raw materials. This, however, is really a rebranding of a long-established norm in Europe.

Since 2010, cements other than CEM I have constituted over 75% of average annual cement deliveries across Cembureau member countries (all cement-producing EU member states, plus Norway, Serbia, Switzerland, Turkey, the UK and Ukraine). This statistic breaks down differently from country to country. CEM II is the norm in Austria, Finland, Portugal and Switzerland, with deliveries in the region of 90%. Portland limestone cement (PLC) makes up a majority of deliveries in all four. It has been central to Switzerland’s transition to 89% (3.72Mt) of CEM II deliveries out of a total 4.18Mt of cement despatched in 2021. There, the main types of cement were CEM II/B-M (T-LL) Portland composite cement, with 1.38Mt (33%), and two different classifications of PLC: CEM II/A-LL PLC, with 1.28Mt (31%), and CEM II/B-LL PLC, with 888,000t (21%).

A second approach is that of the Netherlands, where CEM III blast furnace slag cement with a clinker factor below 65% predominates, favoured for its sulphate resistance and the protection it offers against chloride-initiated corrosion of steel reinforcement in marine settings. By contrast, the UK has traditionally maintained a higher reliance on CEM I cement. This can be partly explained by the preference of builders there for adding fly ash or ground granulated blast furnace slag (GGBFS) at the mixing stage. Nonetheless, CEM II Portland fly ash cement held a 14% (1.43Mt) market share in the UK’s 10.2Mt of cement consumption in 2021.

The UK Mineral Products Association (MPA) has identified limestone as an underutilised resource in the country’s cement production. Together with HeidelbergCement subsidiary Hanson Cement, it has applied for a change to National Application standards to allow the production of Portland composite cement from fly ash and limestone or GGBFS and limestone. The association has forecast that Portland composite cement could easily rise to 30 – 40% of UK cement consumption, and that this has the potential to eliminate 8% of the sector’s 7.8Mt/yr-worth of CO₂ emissions.

Metallurgical waste streams have long flowed into European cement production, primarily as GGBFS, but also as bauxite residue. In 2021, alumina production in the EU alone generated 7Mt of bauxite residue, of which the bloc recycled just 100,000t (1.4%) that year. Two projects – the Holcim Innovation Center-led ReActiv project and Titan Cement and others’ REDMUD project – aim to produce new alternative cementitious materials from bauxite residue.

By collaborating with other industries, cement producers’ investments can most effectively reduce the overall cost of using these materials in cement production. In Germany, HeidelbergCement and ThyssenKrupp’s Save CO₂ project aims to develop new improved latent hydraulic binders or alternative pozzolan from GGBFS by producing slag from directly reduced iron (DRI). The Save CO₂ team believes that GGBFS substitution for clinker has the capacity to eliminite 200Mt/yr of CO₂ emissions from global cement production.

Meanwhile in the world of mining, ThyssenKrupp and others’ NEMO project is investigating the recovery of a useable mineral fraction for cement production from the extractive waste of the Luikonlahti and Sotkamo mines in Finland and the Tara mine in Ireland, through bioleaching and cleaned mineral residue upcycling. This may give cement producers full access to Europe’s 28Bnt stockpiles of sulphidic mining waste, of which mines generate an additional 600Mt each year.

Denmark-based CemGreen, which produces the calcined clay supplementary cementitious material CemShale, is developing a shale granule heat-treating technology called CemTower. This consists of three pieces of equipment vertically integrated into cement plants’ preheaters, kilns and coolers, and brings the processing of waste materials – here oil shale – to the cement plant.

Lastly, cement producers are exploring the possible uses of waste made of cement itself. In Wallonia, HeidelbergCement subsidiary CBR’s CosmoCem project is investigating the production of alternative cement additives from large available flows of local demolition, soil remediation and industrial waste. Similarly, the Greece-based C2inCO₂ project seeks to mineralise fines from concrete recycling for HeidelbergCement to use in the production of novel cements in its Greek operations.

In Switzerland, ZND Portland composite cement (produced using fine mixed granulate from building demolitions) is the third largest cement type, with 178,000t (4.3%) of total deliveries – narrowly behind CEM I with 239,000t (5.7%).Holcim Schweiz developed its Susteno 4 ZND Portland composite cement with Switzerland’s lack of any ash or slag supply in mind, demonstrating the potential flexibility of a circular economic approach to cement production.

On 21 March 2022, the University of Trier reported that it is in the process of mapping mineral resources, waste deposits and usable residues ‘on a cross-border scale,’ in an effort to produce new materials for use in cement production. Industry participants include France-based Vicat, CBR, Buzzi Unicem subsidiary Cimalux and CRH subsidiary Eqiom. Vicat is preparing a kiln at its 1Mt/yr Xeuilley cement plant in Meurthe-et-Moselle to use in testing new alternative raw materials developed under the project.

For Cembureau and its members, work continues, with the goal of Net Zero by 2050 constantly in sight. This goal includes a reduction in members’ clinker-to-cement ratios to well below 65%. In this, the association and its members are working towards a world not just beyond CEM I, but beyond CEM II, too. What exactly this will mean remains to be seen.

Benelux/France: Cementir Holding has introduced its Futurecem limestone calcined clay cement into the Benelux and French cement markets. Futurecem cement applies Cementir Holding’s patented processes to substitute over 35% of clinker in cement with limestone and calcined clay, preserving the cement’s strength and quality while reducing its carbon footprint by 30% compared to ordinary Portland cement (OPC).

Cementir Holding previously rolled out Futurecem cement in Denmark in 2021. In 2022, it plans to launch InBind high performance concrete (HPC) and ReCover ultra-high performance concrete (UHPC) to expand its range of HPC and UHPCs using Futurecem technology.

Eddy Fostier, managing director of Cementir Holding’s Belgian subsidiary CCB, said “Thanks to the joint efforts of the group and CCB teams, Futurecem technology is the main pillar for CCB’s low carbon transition within the Group roadmap. This product technology is matching customer needs, highlighted through a specific survey carried out across the most relevant market areas and applications.” Fostier concluded “I’m fully convinced that Futurecem will play a relevant role in the decarbonisation of the construction industry, where cement and concrete are essential building materials both in the present and in the future.”
