Sweden: Umeå University is part of the ELECTRA project, a €20m EU initiative aimed at advancing green transition in cement and lime production through electrified processes. This project, involving global industry leaders, is funded under the Horizon Europe initiative and led by VTT Technical Research Centre of Finland.
The Department of Applied Physics and Electronics at Umeå University has collaborated with the Swedish quicklime and cement industry since 2007. Matias Eriksson, director of the Centre for Sustainable Cement and Quicklime Production at Umeå University, said “This is an important project. It is the first Horizon Europe project we are participating in," He continued "We are pleased with the confidence the European Commission, heavy materials industry and other research performers show in our work. ELECTRA can play an important role in the industry's green transition, first and foremost in Sweden and the rest of Europe. But because the technology and the industry are global, the effects can be extensive."
Adbri's lime contract with Alcoa ends early
21 March 2024Australia: Adbri has announced the early termination of its contract to supply quicklime to aluminium producer Alcoa, ending in April 2024 instead of the original plan for six months later. This decision is part of an amendment to meet changing demand. The news comes amid Adbri's ongoing review of its Western Australia lime operations and follows Alcoa's recent production curtailment at its Kwinana refinery. Adbri previously supplied to three Alcoa alumina refineries in Western Australia, but the number was reduced to one in 2021.
Adbri is also in the process of finalising a US$2.1bn buyout with Irish company CRH.
Azerbaijan: The latest figures from the State Statistical Committee show a 35% year-on-year increase in the value of building materials produced in Azerbaijan, to US$102m in January - February 2024. Cement production notably surged to 546,000t in the two-month period, a 30% increase. However, clinker production fell by 17% year-on-year. The production of ready-mix concrete increased by 60%, but construction lime production dropped by 57%. These trends continued an increase in building materials production from 2023, when it rose by 32% from 2022 levels.
Update on Chile, February 2024
14 February 2024A few news stories from Chile give us the opportunity to take at look at the local cement market this week. Firstly, Freehill Mining was keen to promote a new order it has obtained from Cementos Melón. The Australia-based company operates magnetite mineral concessions at Yerbas Buenas, about 500km north of Santiago. The US$180,000 deal starts in March 2024 but the raw material supplier says it is currently negotiating a longer-term supply contract with Melón for larger volumes in the future.
A large order for raw materials is not unusual, although the public nature of the Freehill Mining one suggests that the mining company is promoting itself. The story also highlights the importance of the mining sector in Chile. However, a wider view of the Chilean cement sector could be glimpsed recently from the latest cement despatch data from La Cámara Chilena de la Construcción (CCHC). Despatches fell by 11% year-on-year to 5.2Mt in 2023 from 5.9Mt in 2022. As can be seen in Graph 1, despatches recovered in 2021 following the first year of the Covid-19 pandemic but they have declined since then.

Two of the three larger cement producers have reacted to these market conditions in the last couple of years by cutting costs. Cementos Melón started a restructuring process in late 2022 whereupon it closed down a concrete plant at Penalolen near Santiago and embarked on a spending review. Its income fell by 4% year-on-year to US$182m in the first nine months of 2023, from US$189m in the same period in 2022. Cemento Polpaico followed suit in November 2023 by closing two concrete plants in the Santiago Metropolitan Region and temporarily suspending operations at its Quilicura cement grinding plant with work shifted to the integrated Cerro Blanco plant instead. In June 2023 it reported that its income had risen slightly year-on-year for the first half of 2023, but it noted a loss compared to a profit previously. Cbb (formerly Cementos Bío Bío) managed to avoid the fate of its peers mainly through the performance of its lime division. Its cement and concrete shipments fell by 9% and 15% year-on-year to 775,000t and 750,000m3 respectively in the first nine months of 2023. It blamed the falling sales volumes on a decline in economic activity that dragged upon investment in infrastructure and housing. However, lime shipments grew by 2% following tough trading conditions in 2022 due to high fuel costs, amongst other reasons. Altogether this meant that the company’s earnings before interest, taxation, depreciation and amortisation (EBITDA) rose by 54% to US$44.3m from US$28.8m.
Finally, a third news story this week illustrated one reaction to the poor construction market in Chile, when Unacem Chile announced that it was buying two concrete plants, at San Antonio and Talca. Once the US$1m deal completes, the subsidiary of Peru-based Unión Andina de Cementos (UNACEM) will hold 12 concrete plants in the country. This follows its entry into the market in 2018 when it acquired Hormigones Independencia from Cementos Polpaico. In December 2023 Grupo Gloria subsidiary Cal y Cementos Sur (Calcesur) said that it was preparing to strengthen its presence supplying lime to the mining sector both at home in Peru and in neighbouring countries including Chile. While this isn’t a cement story, Grupo Gloria does operate the integrated Yura plant near Arequipa in southern Peru and this resonates with both the mining and lime sectors.
Chile’s cement market is suffering as the general construction market contracts. Yet as the stories from Freehill Mining and Calcesur show, the mining sector remains a key part of the national economy and this links to the cement industry. Another related story, for example, is a US$39m deal that Denmark-based FLSmidth signed in mid-2023 to supply equipment for a copper mine. Chile’s northern neighbour Peru has a cement sector that is nearly twice as large based on production capacity and some of its producers look internationally for expansion opportunities, as in the example of Unacem Chile. The CHHC didn’t hold back in mid-January 2024 when it said that it forecast that 2024 would be the worst year for investment and construction spending since the late 2010s. Yet it also expects the decline in the construction sector to slow as gains from government infrastructure spending continue to almost counteract falls in the private sector. Until the situation improves, it continues to lobby for economic reforms.

China: Switzerland-based Maerz has commissioned two lime kilns for Guizhou Gangli Xinmin New Material’s plant in Guizhou province. The new plant includes a 600t/day R4S kiln and an 800t/day R5S kiln. Both kilns are coal fired. This is the first time Maerz has supplied kilns to Guizhou Gangli. As part of the project, Maerz supplied engineering and key equipment as well as technical support services for the commissioning and firing of the kilns. Maerz’s long-standing local partner Shanghai Maiyao built the turnkey plants and will operate them on behalf of the customer for the next few years.
Europe: Ireland CRH announced the completion of its divestment of its lime operations in the Czech Republic, Germany and Ireland on 4 January 2024. The deal marks the first phase of the group’s divestment of its entire European lime business, for US$1.1bn.
Mineral Products Association welcomes UK cement carbon border adjustment mechanism plan
19 December 2023UK: The Mineral Products Association (MPA) has welcomed government plans for the implementation of a UK carbon border adjustment mechanism for cement by 2027. The association urged the government to develop policy and business models for carbon capture, use and storage, including supporting a domestic carbon neutral and negative products sector.
MPA executive director for energy and climate change Diana Casey said “We cannot take our supply of cement for granted and neither can we put ourselves at risk of unstable international trading markets. That is why today’s commitment to a UK CBAM is so important. Levelling the carbon cost between domestic production and imports will help the UK attract the investment required to decarbonise and ensure our long-term security of supply. The Government’s commitment to bring in the UK CBAM by 2027 is very welcome, and ideally it should be introduced in 2026 to align with the EU scheme. This is the only way to prevent any detrimental impact of the EU CBAM on UK industry.” She added “As well as a CBAM on cement, the MPA would be interested in exploring a CBAM on lime. However, the challenge for the lime sector is ensuring that lime exports can compete in international markets.”
Australia: Western Australia’s environment minister Reece Whitby has questioned the efficacy of tests submitted by Cockburn Cement in relation to its Munster lime plant in May 2023. The tests showed successes in odour reduction during sand feeding at the plant’s Kiln 6. Business News Western Australia has reported that the government and an independent expert have raised ‘areas of concern’ as to whether the trial represents normal operating conditions for the kiln.
David Scaife, who represents Cockburn District in the Western Australia Legislative Assembly, said "My gripe is not with the workers, it is with the senior management and the directors of Cockburn Cement and its owner, Adbri, who have refused to do the right thing either by moving the lime manufacturing operations to its Kwinana facility or at least making the investments necessary to eliminate the odour."
SigmaRoc buys CRH’s European lime business
22 November 2023Europe: Ireland-based CRH has agreed to sell its European lime business to UK-based SigmaRoc for US$1.1bn. The business controls 16 sites across the Czech Republic, Germany, Ireland, Poland and the UK. CRH says that the first phase of the transaction, which is scheduled for completion in early 2024, will hand over control of the Czech Republic, Germany and Ireland businesses to SigmaRoc, while control of the Poland and UK business will pass over in two subsequent phases.
CRH chief executive officer Albert Manifold said “The decision to divest at an attractive valuation follows a comprehensive review of the Business and demonstrates CRH’s active approach to portfolio management. The proceeds from the divestment will provide us with significant additional capital allocation opportunities to deliver further growth and value creation for our shareholders.”
Cemex UK supplies by-pass dust to farmers
24 October 2023UK: Cemex UK says that it has collected 130,000t of by-pass dust (BPD) from its Rugby cement plant in Warwickshire since 2015. The producer supplies the BPD to the agriculture sector, where it can replace traditional fertilisers and lime due to its high lime and potassium content. Additionally, Cemex UK has sponsored research into this and other circular economic uses of BPD, including an on-going study which claimed the Carbon Journey Award at the Eco Innovation North West Awards 2023.
Cemex’s Europe regional head of sustainability Paul Fletcher said “We are very proud of our partnership with Silverwoods and the considerable positive impact their innovation and expertise has had on our ability to reuse BPD for other applications. We believe it leads the way in our industry and presents real potential to be adapted elsewhere across our operations. Not only does it benefit the environment by reducing the amount of materials that need to be disposed of, but it generates a product that has a value for farmers and helps cut the use of traditional materials.” He added “This partnership demonstrates that to deliver true circularity, more industrial by-products, including those from different sectors of the economy, need to be used as secondary resources, rather than primarily be seen as waste. If this is to be achieved, a new perspective is needed to boost circular economy practices, with regulations and permitting supporting this proactively.”
