US: Buzzi Unicem USA plans to switch from producing Ordinary Portland Cement (OPC) to Portland Limestone Cement (PLC) at all of its plants by the end of 2022. It said that it intends to transition from traditional ASTM C150 type I and II (OPC) cements in favour of ASTM C595 type IL cement (PLC). So far its Cape Girardeau and Festus plants in Missouri, Greencastle plant in Indiana, Maryneal plant in Texas and Pryor plant in Oklahoma have already completed the move to the PLC. The San Antonio plant in Texas will complete its transition in June 2022, the Chattanooga plant in Tennessee will switch its product line by September 2022 and the Stockertown cement plant in Pennsylvania will complete its conversion later in 2022. The company added that its engineers will continue working to increase the limestone content in cement by up to the permitted 15% and develop High Early Limestone cement, along with other new cement products with reduced clinker content.
Italy: Buzzi Unicem’s net sales grew by 17.2% year-on-year to Euro800m in the first quarter of 2022 from Euro682m in the same period in 2021. Its cement and ready-mixed concrete sales volumes rose by 2.9% to 6.36Mt and 6% to 2.69Mm3 respectively. The group reported growing sales volumes in Central Europe, Poland, the Czech Republic and the US but it noted a slowdown in Italy. Sales volumes were also disrupted in Ukraine and Russia due to the ongoing war between the countries. The group added that its prices were ‘markedly’ up in all markets where it operates to offset rising prices of raw materials and energy.
The company said that in Ukraine it was forced to suspend nearly all of the production and commercial activities at both of its plants when Russia invaded the country. In Russia it said that retaliatory economic sanctions led by the US and European Union had led to a “significant revision of the country's growth prospects.” Local sales volumes significantly slowed down in March 2022 after hostilities started but local operations still managed to report some growth in sales even in spite negative currency exchange effects. Buzzi Unicem said that, “Due to the sanctions imposed on Russia by the European institutions, we decided to immediately withdraw from any operational involvement in the activities carried out by the subsidiary OOO SLK Cement in Russia. Consequently, further strategic initiatives in the country will be suspended.”
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.
Domicem awards upgrade of limestone reclaiming system at San Cristobal plant to Bedeschi
04 May 2022Dominican Republic: Colacem Group subsidiary Domicem has awarded the contract to upgrade the limestone reclaiming system at its integrated Sabana Grande de Palenque cement plant in San Cristóbal province to Italy-based Bedeschi. The original stacking and reclaiming equipment, installed by Bedeschi in 2004, allows clay and limestone handling at the plant. The upgraded machine will improve the limestone reclaiming system, increasing its capacity from 200t/hr to 360t/hr, the capacity needed in order to feed a new production line that is being installed at the plant.
Buzzi Unicem records earnings growth in 2021
29 March 2022Italy: Buzzi Unicem’s earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 1.8% year-on-year in 2021 to Euro795m. Despite this, its net profit for the year declined by 3.2% year-on-year to Euro542m.
In 2022, Buzzi Unicem forecasts a 10% full-year EBITDA decline due to the impacts of the Russian invasion of Ukraine.
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.

Austria: Alpacem has held the groundbreaking ceremony for the construction of its new headquarters at Wietersdorf, Carinthia. The company will invest Euro6m to establish the new headquarters on the site of its Wietersdorf cement plant. It will contain 50 office work stations, with meeting rooms and socialising zones.
In 2021, Alpacem says that it supplied 2Mt of cement and 350,000m2 of ready-mix concrete to projects in the Alpine/Adriatic region.
Buzzi Unicem launches CGreen reduced-CO2 cement in Germany and Italy
24 February 2022Germany/Italy: Italy-based Buzzi Unicem has launched its CGreen reduced-CO2 cement on the German and Italian cement markets. The product uses alternative raw materials to partially replace clinker and also optimises grinding and mixing conditions through the use of novel specialist additives. In Germany, the available range of CGreen cements will consist of Dyckerhoff Eco Comfort cement and Dyckerhoff Cedur cement.
Italy cemeny chief operating officer Antonio Buzzi said "The ecological transition calls for us to adapt our behaviors and actions in order to neutralise our carbon footprint. This transition implies the partial or total redesign of production processes, distribution systems and consumption patterns, heralding the start of a potential industrial revolution and a change in our habits."
Buzzi Unicem increases sales in 2021
10 February 2022Italy: Buzzi Unicem’s full-year consolidated sales rose by 8.9% in 2021 to Euro3.45bn. The group also increased its cement sales, by 6.7% to 31.2Mt.
Buzzi Unicem’s net financial position for the year was Euro231m, compared to a loss of Euro242m in 2020.
Cementir’s revenue grows by 11% to Euro1.36bn in 2021
09 February 2022Italy: Cementir’s revenue grew by 11% year-on-year to Euro1.36bn in 2021 from Euro1.22bn in 2020. Its earnings before interest, taxation, depreciation and amortisation (EBITDA) grew by 17.9% to Euro311m from Euro264m. Sales volumes of cement and concrete increased by 4.1% to 11.2Mt and 14.8% to 5.01Mm3 respectively.
“2021 marked for Cementir the year of the historic record of revenues and EBITDA despite the uncertainties related to the pandemic crisis, the substantial increase in energy costs, materials and services and the devaluation of the Turkish lira,” said Francesco Caltagirone Jr, chair and chief executive officer of Cementir.
The group also reviewed and approved the three-year Group Industrial Plan update for the period 2022 - 2024 and the 2022 budget. It has a target of reduce CO2 emissions (scope 1) by 30% in 2030 compared to 1990 levels. It is also planning to invest Euro116m in the 2022 – 2025 to meet this goal and others. Some of this will go towards building a new production line at its integrated Gaurain cement plant in Belgium, where the work is intended to raise the unit’s alternative fuels substitution rate to 80% from 40%. The group noted that this project has been delayed to 2022 due to the coronavirus pandemic. Changes at other cement plants include switching to natural gas and biogas as well as energy efficiency projects. It is also said it was planning to ‘significantly’ increase the production of its FUTURECEM calcined clay cement and related sustainable products.
