Holcim Deutschland’s Lägerdorf cement plant to receive oxyfuel kiln and carbon capture system
18 July 2022Germany: Holcim Deutschland announced a planned upgrade to its Lägerdorf cement plant’s kiln on 14 July 2022. The producer will install a second generation oxyfuel kiln, which uses an air separation unit to supply oxygen directly, emitting CO2-rich flue gas. A new carbon capture system will supply captured CO2 to a synthetic hydrocarbons plant, which will produce methanol for other industrial applications. The upgrade will result in the capture of 1.2Mt/yr
of CO2 emissions and make Lägerdorf one of the world’s first carbon neutral cement plants, according to Holcim Deutschland.
The project, called Carbon2Business, was among four cement plant projects and 13 other EU-wide projects to win a share of a US$1.81bn EU Innovation Fund funding pot. CEO Thorsten Hahn acknowledged that the awarding of funds was ‘good news for Holcim and all partners working with us to decarbonise cement.’ He said “Climate change means cement change.”
Bulgaria/Poland: The EU Innovation Fund has awarded funding to Devnya Cement’s ANRAV carbon capture, utilisation and storage (CCUS) project in Bulgaria and Lafarge Polska’s Go4ECOPlanet CCUS project in Poland.
ANRAV is a full-chain CCUS project connecting Devnya Cement’s Devnya cement plant in Varna Province over 30km to the Black Sea for storage. Go4ECOPlanet applies a similar model to the capture and storage of CO2 from Lafarge Polska’s Kujawy cement plant offshore in the North Sea. The Kujawy cement plant is situated 200km inland in Kuyavian-Pomeranian Voivodeship. The plan is part of Lafarge Polska’s strategy to realise carbon neutrality at the Kujawy cement plant by 2027.
Regarding the ANRAV project, Mihail Polendakov, Bulgaria, Greece and Albania managing director at Devnya Cement’s parent company HeidelbergCement said “Our vision in the ANRAV consortium is to realise an economically viable CCUS cluster for Bulgaria and the neighbouring regions.” He continued “Subject to regulatory and permissions aspects, it could start operation as early as 2028, with a capture capacity of 800,000t/yr of CO2.
Update on slag cements, July 2022
13 July 2022A trio of slag cement stories have been in the sector news this week with reports from Australia, France and Sri Lanka. Of note from the first two reports is a focus on supplies of slag.
The first concerns Hallett Group’s US$80m supplementary cementitious materials (SCM) project in South Australia. This will see the company process slag and fly ash sourced from sites in the region to manufacture blended cement products and standalone SCMs. These will be principally milled, blended and distributed from a site at Port Augusta. However, an additional distribution site at Port Adelaide is also planned that can both import and export the company’s products in a bid to cut down on supply chain risk, particular for its mining customers. The company says it will replace up to 1.15Mt/yr of cement when fully operational, although initial production looks set to be about a third of this based on local media reports. Commissioning of the Port Adelaide distribution hub is scheduled for May 2023, following by the Whyalla Granulator in January 2024 and the Port Augusta processing plant in June 2024. Pointedly, Hallett Group is explicit about where is plans to source its SCMs from: Nyrstar Port Pirie and, potentially, Liberty GFG.
The second slag-themed story hails from France, where Hoffmann Green Cement has acquired ABC Broyage, which operates a slag grinding plant in North Dordogne. Like the project in Australia above, Hoffmann Green is focused on its supply chain. With this acquisition it will be able to grind its own blast furnace slag instead of buying it. Raw blast furnace slag will be imported via the port of La Rochelle where the company has storage silos. It will then be ground at the former ABC Broyage site and sent on to Hoffmann Green’s H1 and H2 production sites, located at Bournezeau in the Vendée region. Finally it will use it to manufacture its H-UKR and H-IONA cement products. There is no mention of how much the acquisition is costing Hoffman Green. Instead the emphasis, according to company founders Julien Blanchard and David Hoffmann, is very much to, “strengthen our control over our supply and secure our margins in the current highly inflationary context.”
Finally, the week’s third slag-themed cement story is from Sri Lanka, where local media reports that Insee Cement has started producing Portland Composite Cement, using SCMs such as slag, at its Ruhunu grinding plant. This story follows the trend of cement producers around the world switching to greater usage of blended cements, often for sustainability reasons. Unfortunately, political events in Sri Lanka are overshadowing everything else locally, with the president having fled amid social unrest provoked by the ongoing and severe economic crisis. To this end Insee Cement has astutely also donated medical supplies this week to the intensive care unit at the Colombo National Hospital.
These slag stories are important for the cement sector can be demonstrated by a recent update to the Center for International Climate and Environmental Research - Oslo’s (CICERO) research on global CO2 emissions from cement production. When it published its estimate for 2021 it found that overall emissions were 2.6Bnt in 2021 or just over 7% of the world’s total CO2 output. What is worse though, is that its data suggests that cement-based emissions have steadily grown year-on-year from 1.2Bnt in 2002. Apart from a dip in 2015 they have kept on rising! This can mostly be attributed to the growth of the Chinese cement industry in the early 2000s suggesting that a tipping point may be reached in the current decade as lowering cement production CO2 intensity finally kicks in.
Slag and other SCM-based blended cements fit in here as they are one of the ‘easiest’ ways to reduce the clinker factor of cement and concrete and thereby reduce the sector’s CO2 levels. Hence they keep popping up on the various roadmaps and reports for the cement industry to reach net zero. The flipside of this however is that slag is becoming harder to source as the demand for granulated blast furnace slag increases and less new steel plants get built, especially in North America and Europe. Hence the focus on the supply of slag in the first two news stories above. Blended cements may be the future but getting there will be far from simple.
Australia: Hallett Group plans to establish a slag cement grinding plant in Port Augusta, South Australia. Magnet News has reported the cost of the project as US$83.9m, towards which the producer has received US$13.4m in government funding. The plant will produce cement using South Australian ground granulated blast furnace slag (GGBFS) from Nyrstar’s Port Pirie and Liberty Primary Steel’s Whyalla steel refineries and fly ash from the site of the former Port Augusta power plant. Its operations will be 100% renewably powered. An accompanying new distribution facility at Port Adelaide will ship the cement to markets. The project will create 50 new jobs.
When the Port Augusta grinding plant becomes operational in 2023, its products will reduce regional CO2 emissions by 300,000t/yr, subsequently rising to 1Mt/yr, according to the company’s expansion plans.
Hallett Group chief executive officer Kane Salisbury said "We're talking about 1% of the entire country's 2030 [CO2 reduction] commitment, delivered through this project." Salisbury added "We're looking at turning South Australia into a global leader in manufacturing green cement."
France: Hoffmann Green Cement Technologies has acquired ABC Broyage, which operates a slag grinding plant in North Dordogne. The producer says that ABC Broyage will import granulated blast furnace slag (GBFS) via La Rochelle and supply ground GBFS to its H1 and H2 green cement plants in Bournezeau. This will give Hoffmann Green Cement Technologies self-sufficiency in its raw materials processing.
Co-founders Julien Blanchard and David Hoffmann said “Managing our supply chain has always been one of Hoffmann Green's strategic priorities. After securing our supplies of co-products and their storage, we are now focusing on optimising their processing through the acquisition of ABC Broyage and the development of vertical integration.” Blanchard and Hoffmann noted that, besides strengthening the company’s control over its raw materials supply, ABC Broyage’s slag grinding capacity also secures its margins in the ‘current highly inflationary context.’
Hoffmann Green Cement Technologies launches Swiss joint venture with construction company
06 July 2022Switzerland: Hoffmann Green Cement Technologies has launched a new joint venture with a Switzerland-based construction industry partner. Hoffmann Green Cement Technologies will hold a minority stake in the new subsidiary, which will produce its reduced-CO2 clinkerless cement at an upcoming plant. The producer says that the unit will apply the vertical production model of its existing H2 plant in France.
Co-founders of Hoffmann Green Cement Technologies Julien Blanchard and David Hoffmann said "After signing our first contract outside France more than a year ago, we are proud to accelerate our international development through a licensing model for Hoffmann Green technologies and processes. The opening of this first subsidiary in Switzerland proves the attractiveness of our carbon-free solution without clinker outside our borders, and constitutes a structuring step in the development of Hoffmann Green."
