LafargeHolcim US reveals more detail on carbon capture study at Ste. Genevieve cement plant
03 November 2021US: LafargeHolcim US has revealed more information about a commercial-scale carbon-capture study based at its integrated Ste. Genevieve cement plant in Missouri. The project aims to deliver a front-end engineering design (FEED) study for a carbon capture retrofit that can separate up to 95% of CO2 emissions at the plant. The captured CO2 will be ‘pipeline ready’ for geological storage and analysis of the project socio-economic impact will also be part of the study. The US Department of Energy’s National Energy Technology Laboratory awarded US$4m to the Prairie Research Institute at the University of Illinois to work on the project in early October 2021. LafargeHolcim and Air Liquide are also making cost share contributions.
The design will use Air Liquide’s Crycocap FG system at the cement plant. LafargeHolcim US says that it combines pressure swing adsorption capabilities with cryogenic refrigeration technologies to achieve high CO2 capture rates with high CO2 purity rates. Notably, for a carbon capture project, the Ste. Genevieve plant has one of the largest single clinker kilns in the world.
Pakistan: Fauji Cement says that two planned cement plant projects will increase its total cement production capacity by 64% to 10.5Mt/yr by mid-2023, from 6.4Mt/yr at present. The producer plans to establish a 2.05Mt/yr cement plant at Dera Ghazi Khan. After its commissioning before mid-2023, the plant’s capacity will more than double to 5.65Mt/yr. Subsidiary Askari Cement is expanding its 2.8Mt/yr Nizampur cement plant’s capacity by 73% to 4.85Mt/yr. The group estimates that the total 4.1Mt/yr-worth of new capacity will increase its national cement market share to 13% from 6.7%. It says that this will make it the second largest cement company active in Northern Pakistan, after Bestway Cement.
Fauji Cement said that it is well positioned for growth. It generated 70% of the power consumed in its operations in 2020 itself.
HeidelbergCement expands in Tanzania
27 October 2021Interesting move from HeidelbergCement this week with the news that it has agreed to buy a cement plant in Tanzania. The Germany-based multinational producer has signed a deal to buy a 68% stake in Tanga Cement from South Africa-based AfriSam. There has been no indication of the price but the arrangement will give HeidelbergCement a 1.3Mt/yr integrated plant in the north of the country along with a limestone quarry with reserves to last 30 years. The transaction is expected to close in the second quarter of 2022. HeidelbergCement says it then hopes to buy the remaining shares in the company.
HeidelbergCement already operates one integrated plant in Tanzania, Tanzania Portland Cement’s (TPC) Wazo Hill Plant in the capital Dar es Salaam. It took control of the plant in the early 2000s when its subsidiary Scancem International purchased over half of the company’s shares. The plant commissioned a new cement mill in 2014 to increase its production capacity to 2Mt/yr. Local press reported in April 2021 that the subsidiary planned to invest US$15m towards modernising the unit in 2021. It sells cement under the Twiga brand.
Tanga Cement runs a plant near Tanga that was originally commissioned in 1980. Holcim took it over in the mid-1990s before South-Africa based AfriSam assumed control in the early 2010s. The plant commissioned a second production line in 2016 and it has a production capacity of 1.3Mt/yr. It sells cement under the Simba brand.
HeidelbergCement’s decision to buy a plant in Tanzania is noteworthy because it goes against the general trend in acquisitions by western-based multinational cement companies in recent years. Instead of shrinking away from markets in developing economies and doubling-down on ‘safe havens’ in mature markets it has bought a plant in a developing country. Although one might argue that it does fit the definition of a well-chosen bolt-on acquisition.

As Graph 1 above shows, cement production in Tanzania has more than doubled over the last decade, from 2.4Mt in 2011 to 6.5Mt in 2020. Tanzania Portland Cement estimated local demand at 5.9Mt, including exports, in 2020. This was against a total cement production capacity, from both integrated and grinding plants, of 11Mt/yr. As well as the TPC and Tanga Cement plants mentioned above, Holcim runs an integrated plant in Mbeya and Huaxin Cement operates one near Tanga. Alongside this, new integrated plants have opened including Lake Cement’s 0.5Mt/yr Kimbiji plant in 2014 and Dangote Cement’s 3Mt/yr Mtwara plant in 2015. The big project on the horizon is a proposed 7Mt/yr integrated plant from China-based CNBM/Sinoma, although not much has been heard publicly about it since mid-2020. At that time local press was reporting that compensation was being finalised for residents of the proposed site near Tanga. Needless to say, given the size of the plant compared to the Tanzanian cement market, much of the plant’s output is intended for export.
With the CNBM plant in mind, it is noteworthy that HeidelbergCement committed to buying an extra plant in the country. Production has been going up over the last decade to presumably meet demand but the new Chinese project could potentially blot out the entire existing production. Tanzania faced a cement shortage at the end of 2020 despite coronavirus. TPC has repeatedly warned of production overcapacity in Tanzania and the challenges of competition. Yet it reported a new sales record in 2020 and growth of 7% in the national cement market. Despite a 5Mt overcapacity, TPC says it managed to adapt to the new market conditions. It also managed to grow its operating profit by 20% year-on-year to around US$46m in 2020 compared to HeidelbergCement Group’s 8% rise in results from current operations in 2020. This kind of return no doubt helped HeidelbergCement to make up its mind.
Russia: Kavkazcement has announced that it will use its Kavkaz cement plant's annual shutdown in the winter of 2021 - 2022 to upgrade the plant's raw materials mills and kiln lines. The Eurocement subsidiary plans to spend US$7.14m on the work, which also includes the replacement of burners in kilns 2 and 4 and the installation of new drying drums, compressors and electrostatic precipitators. The upgrade will increase the 3Mt/yr plant's cement capacity by 10% and its clinker capacity by 30%. Managing director Vladimir Sokoltsov said that the upgrade focused on minimising the plant's environmental impacts.
Sokoltsov said “We will prepare the plant for the high construction season in April 2022. Our products are used in the construction of the largest industrial, transport and municipalinfrastructure in southern Russia." He continued "We understand that the quality of life of a large number of people depends on the pace of our work.”
Roof collapses over cement mill at Lafarge Zimbabwe plant
27 October 2021Zimbabwe: Lafarge Zimbabwe says that a ‘critical’ incident occurred at its Manresa plant in Harare on 11 October 2021 when the roof collapsed over a cement mill. It reported no fatalities or injuries. However, the subsidiary of Switzerland-based Holcim warned that the incident might have an impact on its business performance for the last quarter of 2021. It added that it had already started taking action to repair the structure and restart the mills.
The Herald Zimbabwe newspaper reports that there has been a “general low visibility of the company’s cement in the market.” It added that the company started building a new cement mill at the plant in March 2021 with an expected commissioning date of March 2022.
Switzerland: Jura Cement has installed a PREMAS 4.0 continuous monitoring system supplied by Aumund at its Wildegg cement plant. The system informs operators about the condition of the equipment used in cement production at the plant in real time via the PREMAS Cloud. It also provides service life estimates for critical components.
The Wildegg plant previously hosted a prototype PREMAS 4.0 in early 2020.
Head of Maintenance Ramona Keller said “We are convinced that predictive maintenance has a future. With PREMAS 4.0, we can better plan spare parts and maintenance, which has a positive effect on resources and costs. The PREMAS Portal is easy to use and very clear. It enables us to recognise immediately where there is a need for action, regardless of time and place."

LafargeHolcim Croatia commissions Gasmet continuous mercury monitoring system at Koromačno cement plant
27 October 2021Croatia: LafargeHolcim Croatia has successfully commissioned a continuous mercury monitoring system in the stack of its Koromačno cement plant in Istria. Gasmet supplied the system via its regional distributor RACI.
LafargeHolcim Croatia Production Engineer Ivan Marićsaid “The product gives us exactly what we want – peace of mind. We now know where we stand with our mercury emissions.”
South Africa: Sephaku Cement has reported a second unexpected kiln stoppage at its integrated Aganang plant in Lichtenburg. It attributed the second delay on the need for a repair to the inside of the kiln. The second stoppage started on 16 October 2021 and was expected to be completed by 26 October 2021. Previously, the kiln was stopped from 30 September 2021 to 6 October 2021 due to preheater refractory material damage caused by a corrosive element in one of the raw materials being used. The producer said that the raw material was subsequently replaced with an alternative option. The subsidiary of Nigeria-based Dangote Cement said that the outages were expected to reduce its sales volumes.
Cementa preparing to ration supplies in December 2021
27 October 2021Sweden: Cementa says it is preparing to ration deliveries of cement in December 2021 due to uncertainty about whether it can renew the mining licence at its integrated Slite plant in Gotland beyond the end of October 2021. The subsidiary of Germany-based HeidelbergCement has warned customers that it is preparing to implement quotas of cement products from its two plants and five terminals on a week-by-week basis. The quotas will be based on what level of cement customers have ordered previously over the past 36 months. It will also take into account whether there have been significant volume changes during the period.
Cementa says it submitted its application for an emergency permit in late September 2021. It needs approval from the government by mid-November 2021 to avoid a potential cement shortage. However, any such approval may be subject to an appeal leading to further delays in mining.
