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.
Federbeton publishes 2019 sustainability report
03 December 2020Italy: The Italian cement and concrete association Federbeton says that investments in sustainable technologies in domestic cement production totalled Euro110m between 1 January 2017 and 31 December 2019. This reduced carbon dioxide (CO2) emissions by 311,000t in 2019 alone, up by 12% year-on-year from the reduction in 2018. An increased alternative fuel (AF) substitution rate of 6.7% in 2019 contributed to the reduction, up by 0.7% from 6.6%. Producers’ full-year AF consumption was 1.6Mt.
Lafarge Zementwerke appoints A TEC for Mannersdorf cement plant alternative fuels Flash Dryer installation
24 November 2020Austria: Loesche subsidiary A TEC has won a contract for the supply and installation of a Flash Dryer for alternative fuels (AFs) in the kiln line of Lafarge Zementwerke's 1.1Mt/yr Mannersdorf cement plant in Lower Austria. The supplier said that it will complete the project in early 2021.
The company said, “Reaching high thermal substitution rates (TSR) requires firing of alternative fuels at the kiln burner. To reach a stable sintering zone for the required clinker quality a high fuel quality (high LCV, small particle size) is needed, otherwise the clinker quality may suffer or the TSR can be limited. With the A TEC Flash Dryer various waste heat sources can be used (clinker cooler flue gas, bypass gas, preheater gas, etc.). The material is dosed to the hot gas flow in the flash dryer and transported with this gas flow, while the moisture is evaporated, to a cyclone and a subsequent filter where the fuel is separated from the gas flow and on-line fed to a kiln burner or a satellite burner. In addition to the drying the lifting effect of the gas can separate 3D impurities which contributes in a further increase of the fuel quality.”
SungShin Cement orders two FLSmidth HotDiscs
10 November 2020South Korea: SungShin Cement has placed an order with Denmark-based FLSmidth for the supply of two HotPlate combustion devices for installation in lines three and six of its SungShin cement plant. The plant is in the transition from coal fuel to the possibility of 100% alternative fuel (AF) use in the two lines, which it plans to commission in mid and late 2021 respectively.
Team manager of production technology Cho K-R said, “With its degree of flexibility, the HotDisc allows us to substitute coal with a wide range of AFs – refuse-derived fuel (RDF) in our case. As we turn waste into energy, the HotDisc lowers our operating costs without compromising energy efficiency.”
FLSmidth previously delivered two HotDiscs to South Korea, to SsangYong’s Donghae and Yeongwool cement plants.
