W&P Zement becomes Alpacem Zement Austria
08 August 2023Austria: Alpacem's Austrian subsidiary W&P Zement has announced its rebranding to Alpacem Zement Austria. Alpacem said that the rebrand in Austria will be the first step of a roll-out of the Alpacem brand across its local subsidiaries.
Alpacem has subsidiaries in Austria, Italy and Slovenia.
Austria/Germany: Rohrdorfer Group and gas network company Bayernets have published a feasibility study for a proposed CO2 transport network in Bavaria in Upper Austria. The first stage of the CO2peline plan will be to create an ‘island’ network between the Rohrdorfer cement plant in Upper Bavaria and the so-called ‘Bavarian chemical triangle.’ An additional connection to the industrial and chemical region of Linz in Austria would add additional CO₂ sources, places of use and temporary storage sites to the grid. Further expansion plans could see the network expanded to cover the whole of Bavaria. A future connection to a Germany-based national network and international routes could further link the network to other locations where CO2 is both produced and used, as well as creating routes to sequestration sites.
No dates have been released for the proposed CO2 pipeline network. However, the project notes that Germany is aiming for carbon neutrality by 2045 and Bavaria and Austria by 2040.
Austria: Rohrdorfer has bought 20 new railcars equipped with ÖBB Rail Cargo’s RockTainer SAND containers. The cars will transport limestone between the producer’s Ebensee quarry and its Gmunden cement plant. Each railcar consists of two RockTainer SAND containers mounted on an InnoWaggon carriage, with a maximum load of 134t. The new cars will increase the volume of despatches from the Ebensee quarry by 28% to 804t of limestone per train from 630t/train, enabling Rohrdorfer to transport 450,000t of limestone per operating season.

05 April 2023Austria: RHI Magnesita has appointed Peter Steinkellner as Head of Technical Marketing Cement & Lime for Europe, CIS & Türkiye. He has held a number of marketing roles for the refractory producer since 2015. Prior to this he worked Lafarge for seven years as a quality engineer.
Eternit Österreich rebrands to Swisspearl Österreich
24 March 2023Austria: Fibre cement products company Eternit Österreich will rebrand as Swisspearl Österreich, effective from 1 April 2023. The company has been a subsidiary of Switzerland-based Swisspearl Group since 2009.
RHI Magnesita reports 'solid performance' in 2022
27 February 2023Austria: RHI Magnesita reported revenues of Euro3.3bn throughout 2022, up by 30% year-on-year from 2021 levels. The refractories supplier's raw materials and shipping costs rose, but it was able to offset the rise by increasing its prices. The company said that this generated Euro600m in additional revenues, enabling it to maintain profitability 'through a challenging economic cycle.' It noted global volatility and uncertainty, which it expects to continue into 2023, for which it forecast a full-year drop in global cement demand. It expects 'strong growth' in India to offset any resulting decline in its sales in other markets.
RHI Magnesita CEO Stefan Borgas said "I am pleased to report growing progress on our mergers and acquisitions strategy, with acquisitions in India, China, Türkiye and Europe agreed or completed during the year. Whilst the outlook for 2023 is more uncertain than prior years due to slowing demand for refractories and softer pricing in certain regions, RHI Magnesita is able to face these challenges in a much stronger condition as a result of the implementation of its strategic cost savings and sales strategies over the past four years."
RHI Magnesita invests in MCi Carbon on decarbonisation deal
15 February 2023Austria: RHI Magnesita has invested in Australia-based MCi Carbon as part of a long-term strategic cooperation agreement to research and develop technologies to decarbonise the production of refractories. MCi Carbon sells a mineral carbonation process that creates a range of low-carbon embodied materials, including calcium and magnesium carbonate by carbonating minerals in by-products of industrial processes. RHI Magnesita intends to use this process to reduce its Scope 1 emissions from mineral processing during its refractory production process.
Stefan Borgas, the chief executive officer of RHI Magnesita, said "This partnership could become a breakthrough towards decarbonising the industry. It fits seamlessly with RHI Magnesita's ambitious sustainability strategy." He added "We still have a long way to go but our early-stage investment and the clear intention of a long-term collaboration make this day so memorable. Together with the like-minded team from MCi we will pave the way for a greener industry."
So far, both companies have worked together on CO2 mitigation studies, mineral carbonisation feedstock assessments and techno-economic analyses at RHI Magnesita's sites around the world. In a next step, the companies' joint efforts will focus on industrial scale-up, expected to start in 2024 with the set-up of a demonstration plant by MCi at Newcastle in Australia, supported by the Australian government.
Update on construction and demolition waste, February 2023
01 February 2023Cemex launched a new waste management division called Regenera this week. Cemex describes Regenera as a “business that provides circularity solutions, including reception, management, recycling, and coprocessing of waste.” The Mexico-based company has a long and leading history with sourcing and using alternative fuels in the cement sector and the new organisation looks set to utilise this experience. What is notable though is how the business is targeting three waste streams: municipal and industrial; industrial by-products; and construction, demolition and excavation waste (CDEW). Bringing the three waste streams together in this way appears to be novel for the heavy building materials sector, particularly the inclusion of CDEW, which we will explore further here.
CDEW is split into fractions, just like the municipal and solid waste streams that end up as alternative fuels at cement plants, but the biggest fractions are generally concrete, followed by bricks. The recycled concrete is then typically used as an aggregate, either in new concrete production or in areas like road construction and earthworks. The use of recycled aggregates (RA) made from CDEW goes back to at least the 1930s in its current form although ‘reusing’ materials from structures such as castles and churches goes back far further. Recycling and reusing CDEW gained a boost in 2020 when the European Union (EU) set a 70% recovery target. However, within the EU the CDEW recycling rates vary considerably and that 2020 target includes the use of CDEW in backfill applications.
In its launch statement for Regenera, Cemex noted that it operates a dock in Paris, where it receives a variety of materials, including construction debris, excavated material and inert soil. These materials are sorted, processed and then transformed into recycled aggregates or organic material used to restore quarries. Cemex then promptly followed up the official launch of Regenera on 30 January 2023 with the acquisition of a majority stake in Shtang Recycle, an Israel-based CDEW recycling company. It added that Shtang Recycle is preparing to build a recycling plant with a production capacity of 0.6Mt/yr of CDEW waste materials. The output from the plant will be used as raw materials for aggregate production.
The focus on CDEW recycling was flagged up at Cemex’s investor event in November 2022. It said that it was targeting a recycling rate of 14Mt/yr of construction and demolition waste by 2030. Other managed waste stream goals included doubling the amount of municipal and industrial waste it manages, to achieve a 50% to fossil fuel substitution rate, and increasing its usage of alternative raw materials and by-products by 30%, thereby eliminating 13Mt/yr of extracted materials.
Cemex is not alone in targeting the CDEW waste sector. Holcim’s recent work in the area goes back to at least 2016 when a recycling unit near its Retznei cement plant in Austria started processing 130,000t/yr of CDEW. It announced in December 2022 that it was setting up a similar recycling centre, also in Austria, at its Mannersdorf cement plant. In October 2022 Holcim acquired Wiltshire Heavy Building Materials in the UK. This company recycles 150,000t/yr of construction and demolition waste into aggregates and concrete. Holcim linked the acquisition to its Strategy 25 target of recycling 10Mt/yr of construction and demolition waste by 2025.
Activity by other cement companies includes the commissioning of a construction waste recycling plant at Gennevilliers in France by CRH-subsidiary Eqiom in April 2022. It was aiming for a target of 50,000t in 2022. In November 2022 Heidelberg Materials agreed to acquire RWG Holding based in Berlin, Germany. Then, in December 2022, it announced a deal to buy Mick George Group in the UK. Both proposed acquisitions are subject to competition authority approval. Heidelberg Materials’ current target is to offer circular alternatives for half of its concrete products by 2030.
The moves by the bigger cement companies into the CDEW sector follow sustainable thinking and the waste hierarchy. Yet the big prize here is to gain a route to dispose of some of their CO2 emissions through recarbonation and this has been flagged up in several net-zero roadmaps for the cement sector such as those by Cembureau and the Global Cement and Concrete Association (GCCA). Holcim has been involved in the FastCarb project in France, running a pilot at its Val d’Azergues cement plant in 2021. Heidelberg Materials has been testing its own process with so-called recycled concrete paste. The development now appears to be that utilising CDEW has entered the sustainability strategies for some of the big cement-concrete-aggregate producers, targets have been set and acquisitions are happening.

Austria: Lafarge Zement has successfully demolished the chimney of a former gas power plant at its Mannersdorf cement plant in Lower Austria. Hans Zöchling GmbH carried out the demolition work. Lafarge Zement plans to use the cleared space for a new solar power plant. Plant manager Helmut Reiterer said that further renewable power projects are also planned at the site.
Zementwerk Hatschek's Gmunden cement plant eliminates 3800t/yr of local CO2 emissions with WHR heating
24 January 2023Austria: Zementwerk Hatschek's Gmunden cement plant eliminated 3800t of CO2 emissions from its local area during 2022 through its contribution to municipal heating. Zementwerk Hatschek, a subsidiary of Rohrdorfer, heats local households using recovered heat from the Gmunden cement plant's waste heat recover (WHR) system.
A delegation of cement plant representatives and local officials from Baden-Württemberg, Germany, visited the plant to learn about its WHR and heat supply systems on 20 January 2022.
Plant manager Peter Fürhapter said "Municipal heating based on our waste heat contributes to CO2 reduction in Upper Austria, helping us to achieve our CO2 reduction goals under the Paris Climate Agreement." He added "We are pleased that with this forward-looking project we are a model for similar projects in Europe."
