Sweden: Germany-based HeidelbergCement subsidiary Cementa plans to upgrade its Slite unit in Gotland to become the world’s first carbon-neutral cement plant. This will be achieved through modification of the plant’s fuel system to ‘significantly raise’ biobased fuel substitution, as well as 100% carbon capture and storage (CCS) via a 1.8Mt/yr CCS installation. Full-scale capturing of the plant’s CO2 emissions is scheduled by 2030.
Chair Dominik von Achten said, “HeidelbergCement will be the leader in the global cement industry on its transformation path towards climate neutrality. The key for decarbonising our industry is to find, apply and scale technical solutions for carbon capture and utilisation or storage (CCU/S). After having gained valuable experience with CCU/S technologies in Norway and other countries, we are now excited to make the next step with a completely carbon-neutral cement plant in Sweden.”
Portugal: Denmark-based FLSmidth has won a contract to supply a chlorine bypass system to Cimpor’s Souselas cement plant. The aim is to eliminate chlorine build-up in the plant’s flue gas after the company increases its refuse-derived fuel (RDF) usage rate to 60%. Work is scheduled to begin in mid-2021, and production will stop until its completion and the commissioning of the installation in early 2022. No value for the order has been disclosed.
Cimpor Cement project manager Paulo Evangelista said, “Investing in the chlorine bypass is a key step on our journey towards reducing our environmental footprint. On top of the obvious incentives to increase our fuel substitution, like lower CO2 emissions and financial savings, we are experiencing better waste handling infrastructure in the local area. All this has made it an easy choice to make. FLSmidth knows our Souselas site and has been key in delivering a solution that will enable this next phase on our sustainability journey.”
Taiwan: Taiwan Cement’s revenue rose by 11.3% year-on-year to US$788m in the first quarter of 2021. Its income increased by 11% to US$119m. It attributed this to profit growth in its cement businesses in Taiwan and Europe despite ‘weak’ sales prices in China.
Chairman Nelson Chang said, “To reduce carbon emissions, using alternative fuel and material for cement production, adopting renewable energy, and expanding energy storage usage are crucial and Taiwan Cement aims to play our role in helping society achieving the goal of a low carbon environment.” In 2020 the group processed over 9Mt of alternative fuels in its Greater China business.

31 March 2021US: The California Nevada Cement Association (CNCA) has published a plan for the Californian cement industry to meet its target of carbon neutrality by 2045. The plan consists of three pathways, namely: a reduction in process emissions including by alterations to clinker factor and type of additives; an increase in alternative fuel (AF) substitution; and a switch to renewable energy. The association said that the aims are achievable by close stakeholder coordination, constructive public policy engagement and a situational approach based on a flexible portfolio of pathways.
A TEC wins alternative fuels flash dryer contract at Lafarge Hungary’s Királyegyháza cement plant
29 March 2021Hungary: Lafarge Hungary, part of LafargeHolcim, has awarded a contract to Germany-based Loesche subsidiary A TEC for the supply of an alternative fuel (AF) flash dryer for the 1.0Mt/yr kiln line at its Királyegyháza cement plant in Baranya county. The supplier says that the dryer will use residual hot gas from the chlorine bypass system in conjunction with a satellite burner for firing the material in the kiln. The project also includes the installation of a new AF receiving, handling, and dosing system for a second AF flow firing directly into the kiln burner. A TEC says that it will commission the project in the second quarter of 2021 after the end of the plant’s 2020/2021 winter shutdown.
Cemex starts operations at seven sustainable growth investments in Europe in January 2021
22 February 2021Europe: Cemex commissioned seven new bolt-on investments across Europe in January 2021. The company says that all of the investments are aligned to its key priorities of climate action, sustainable construction and earnings before interest, taxes, depreciation, and amortisation (EBITDA) growth. They include advances in fossil fuel reduction, lower CO2 footprint products, circular economy investments and products that demonstrate life cycle CO2 and energy consumption advantages for buildings. It made various changes at its cement plants, for example the installation of a new alternative fuel (AF) system in the Czech Republic. In France and the UK, it made circular economy and recycling improvements, and shifted to lower-CO2 cement production in Croatia and lightweight concrete production in Spain. Additionally, it made efficiency upgrades to sites in Spain and the UK.
Europe, Middle East and Africa regional president Sergio Menendez said, “We have made a strong start to our 2021 ambitions to both grow our business and improve our climate impact. In 2020, we achieved our ambition of a 35% reduction in our CO2 emissions compared to our 1990 baseline in Europe. We are also the first company in our sector to align our Europe operations to the EU aspiration to reduce CO2 emissions by at least 55% by 2030. These investments represent further advances towards this 2030 target, as well as to deliver net zero CO2 concrete globally by 2050.”
Italy: Cementir Holding recorded revenues from sales and services of Euro1.22bn in 2020, up by 1% year-on-year from Euro1.21bn in 2019. Cement and clinker volumes rose by 13% to 10.7Mt from 9.49Mt. Volumes registered the sharpest increase in Turkey, of 39%. Ready-mixed concrete (RMX) volumes grew by 7.8% to 4.4Mm3 from 4.1Mm3. The company maintained its 2019 earnings before interest, taxation, depreciation and amortisation (EBITDA) levels of Euro264m. It said that an improvement in performance in Turkey, Denmark, Egypt, China and Sweden balanced out negative effects on earnings in Belgium, US and Malaysia.
Chair and chief executive officer Francesco Caltagirone said, “In 2020, despite the serious pandemic, the group showed significant resilience with a 13% increase in cement volumes sold and revenue reaching the historical record. On a recurring basis, EBITDA increased by 2%, EBIT was up by 4% and yearly cash generation was Euro119m."
Under Plan 2021 – 2023 Industrial Plan, the company says that it envisages sales growth of 20% to Euro1.47bn and EBITDA growth of 29% to Euro340bn in 2023 compared to 2020 figures. It said that digitalisation investments begun in 2019 will contribute an expected Euro15m to EBITDA in 2023. As part of its sustainability commitments it has set a CO2 emissions reduction target of around 30% by 2030, with emissions below 500kg/t of grey cement. However, it said that under the future European Taxonomy criteria white cement emissions are not included.
The group is planning to invest around Euro107m from 2021 to 2023 on sustainability and digitalisation. This includes a the construction of a new calcination plant in Denmark for the production of its Futurecem product and, the installation of wind turbines with an installed capacity of 8.4MW. It is also planning to increase the alternative fuels substitution rate at its integrated Gaurain plant in Belgian to 80% from 40% and invest in the use of natural gas and biogas in some of its plants.
Beumer Group technical report updates on Covid-19-led changes
29 January 2021Germany: Beumer Group has published a technical report detailing changes to its operations due to the on-going Covid-19 outbreak. The group says that cement producers in some markets have changed to 50kg to 25kg bags. It also reported an increased rate of digitisation, less personal interaction with customers and an increased reliance on alternative fuels.
Cement head of sales Kay Wieczorek said, "Over past months, Covid-19 has forced us to cope with some changes. This will probably bother us even more in the colder months." He added, "Even if the Covid-19 figures are currently in progress, I am sure that BEUMER Group will come through this crisis pretty well; we just have to be well-prepared for it."
France: Vicat started using a CO2ntainer system supplied by UK-based Carbon8 Systems at its Montalieu-Vercieu cement plant in November 2020. It uses captured CO2 from the unit’s flue gas emissions to carbonate cement-plant dust and produce aggregate, which can then be used to make products such as concrete. The system has particular relevance for a plant burning alternative fuels due to the additional chlorinated dust created compared to the use of conventional fossil fuels. The company says it is the first European cement producer to use the process at an industrial scale. Previously, Carbon8 Systems said that its CO2ntainer would process and convert up to 12,000t of cement bypass dust in its first phase of operation.
Vicat Group scientific director Laury Barnes-Davin said, “We were drawn to Carbon8 Systems’ two-part technology: capturing the CO2 that Montalieu emits, and using it to produce an aggregate that can be marketed in the construction industry. It opens up great potential for our operations not just in France but also in all the countries where we work across the globe.” The group hopes to reach a 100% alternative fuel substitution rate in France by 2024.
