Canada: Lafarge Canada signed a tri-partite agreement with Dimensional Energy and Svante Technologies for the construction of a synthetic hydrocarbons plant to use captured CO2 from its Richmond cement plant on 15 May 2023. The upcoming plant will convert the Richmond cement plant's 1t/day captured CO2 emissions into 1.5 barrels/day of synthetic hydrocarbons. The producer, a subsidiary of Holcim, selected this particular solution due to the lack of CO2 transport and sequestration infrastructure in the area of British Columbia where the Richmond plant is located. The project marks Phase 3 of the installation of Lafarge Canada and Svante's carbon capture project at the Richmond plant.
Holcim's Western Canada regional head of sustainability and environment, Stephanie Voysey, said "Carbon capture is an important lever in our net-zero roadmap. However, for a carbon capture project to succeed, it must be paired with permanent geologic sequestration or utilisation technology that will permanently isolate the CO2 in a specific media or product. If this pilot can be scaled to capture and use all facility emissions, it would be a first-of-its-kind project for Lafarge and advance export and global adoption of this technology.”
Nigeria: Lafarge Africa has opened a bag manufacturing unit at its Ewekoro cement plant in Ogun State. It has a bag production capacity of 105m/yr. The company says it is the first of its kind in the country. It is intended to increase the availability of bags through large-scale production locally. The project is a joint-venture run with MDV Industries.
Khaled El Dokani, the country chief executive officer for Lafarge Africa, said “We are using the best technology that produces the most efficient and durable bag in Nigeria. It is a very great day for us at Lafarge Africa.”
Holcim invests in Coomtech
05 May 2023UK: Switzerland-based Holcim has invested in Coomtech, a developer of low-emission kinetic drying technology for raw materials. The group says that Coomtech's technology emits up to 75% less CO2 than traditional drying methods and enables increased use of recycled materials in cement and concrete. Holcim subsidiary Aggregate Industries previously collaborated with Coomtech on fly ash drying at a UK power plant.
Edelio Bermejo, head of global research and development said "At Holcim, we are continuously working to implement greener operations for a net-zero future, and to increase the use of recycled materials in our products to drive circular construction. Coomtech's low-emission drying technology helps us meet both these goals. I look forward to working with them as a key partner in our journey to decarbonise buildings."
Holcim to acquire PASA
04 May 2023Mexico: Switzerland-based building materials group Holcim concluded a deal to acquire the Mexican roofing producer PASA on 3 May 2023. PASA employs 250 people, and generated sales of US$38m throughout 2022.
Holcim said that the deal will help to expand its products and solutions business, an area in which it has now made five acquisitions to date in 2023. Chief executive officer Jan Jenisch expects the group to acquire 30 companies throughout 2023, of which it already acquired 12 during the first quarter of the year.
Belgium: France-based Air Liquide has signed a memorandum of understanding with Holcim to supply and operate a Cryocap Oxy carbon capture unit for the forthcoming upgrade to the Obourg cement plant. The intention is that 95% of the CO2 generated from the new production line will be captured and then transported via the Antwerp@C export terminal for under-sea sequestration. Air Liquide and Holcim have co-applied for the European Innovation Fund to support the project.
Pascal Vinet, Senior Vice President at Air Liquide Group, said “The decarbonisation of the industry is at the heart of our Advance strategy. We are committed to accompany our customers through providing a wide range of innovative solutions. As an example, Air Liquide's proprietary Cryocap technology is particularly well suited to decarbonise the cement industry.”
UK: Aggregate Industries has launched the ECOPlanet product range. The products offer a reduction of at least 30% in the carbon footprint of cement, compared to CEM I ordinary Portland cement, by using second cementitious materials such as fly ash. The launch of the ECOPlanet range is part of the subsidiary of Holcim’s 2030 sustainability strategy, Building Progress for a Sustainable Future.
Dragan Maksimovic, the chief executive officer of Aggregate Industries, said “The launch of ECOPlanet expands on our existing low carbon products including ECOPact, the world’s broadest range of green concrete or Super-Low Carbon, the first asphalt using biogenic material within the bitumen. The product is driven by innovation and by our ambitions to build a net zero future, and we’re delighted once again to be pushing the boundaries of low carbon construction solutions.”
Holcim grows sales and earnings in first quarter of 2023
21 April 2023Switzerland: Holcim’s sales and earnings have risen in the first quarter of 2023 on a like-for-like basis despite the divestment of its India-based business in September 2022. Its net sales rose by 8% on a like-for-like basis to Euro5.84bn in the first quarter of 2023 from Euro6.57bn in the same period in 2022. Recurring earnings before interest and taxation (EBIT) grew to Euro503m from Euro626m. Sales and earnings increased, in real terms, in Europe and Latin America but earnings fell in North America. Both sales and earnings fell in Asia Middle East Africa. Holcim did not comment on the fall in earnings in North America but Reuters noted that US construction spending declined in February 2023 as the housing market coped with increases in the interest rate by the Federal Reserve.
Jan Jenisch, the chief executive officer of Holcim, said "This profitable growth was led by strong performances across our building materials businesses. Our teams continued our fast-paced execution, with 12 value-accretive acquisitions, including Duro-Last, completing our range of flat roofing systems. With strong underlying trends across all our businesses, we are confident we will close the full year strong.” He added that the group reached 16% of ready-mix concrete net sales with its ECOPact product and expanded its ECOPlanet product range with two calcined clay production facilities in France and Mexico. It also launched its ECOCycle technology platform with a target to beat a previous 2025 target of recycling 10Mt/yr of construction, excavation and demolition waste.
US: Holcim US has joined the Department of Energy's (DOE) 'Better Climate Challenge' to reduce CO2 emissions and save energy. It is the first cement producer to commit to the DOE program. The subsidiary of Switzerland-based Holcim plans to power the electrical operations at 13 cement plants in the country with 100% renewable energy by 2030 and to reach net zero CO2 emissions by 2050. As part of the 'Better Climate Challenge' it has committed to reduce CO2 emissions in the US by at least 25% by 2033.
Examples of current renewable power usage at Holcim US cement plants include the installation of three onsite wind turbines at the Paulding plant in Ohio that generate 11,500MWh while a forthcoming solar unit at the Hagerstown plant in Maryland will generate up to 18,440MWh. All 13 Holcim cement plants will conduct reviews to identify projects that could contribute to meeting goals of the challenge.
With grant support from the DOE, Holcim is also investigating the feasibility of using carbon capture utilisation and storage (CCUS) at its cement plants in Portland, Colorado, and Ste. Genevieve, Missouri. In addition to involvement in the Better Climate Challenge, Holcim US is a continuing partner of the DOE's 'Better Plants Challenge', sharing facility-level energy data and solutions to help guide other industrial companies with implementing energy solutions in their facilities.
Building new buildings from old ones
19 April 2023Holcim launched its formal take on construction and demolition waste (CDW) this week with the unveiling of its ECOCycle technology platform at the BAU architecture fair in Munich. This amounts to managing the distribution, processing, grinding and recycling of CDW back into new building material products. It claims that its concrete, cement and aggregate products can contain 10 - 100% of CDW with no drop in performance.
It is hard to gauge whether this is marketing for existing operations or the start of something new. Yet, in its 2022 Sustainability Report, Holcim said that it recycled 6.8Mt of CDW back into building products and that it is on track to meet its target of 10Mt by 2025. This target was neatly put into words as wanting “to build more new buildings from old ones.” Ahead of the announcement of the launch of ECOCycle, it added that it was going to roll out its Susteno product around Europe. This product, made from 20% CDW, was originally released in Switzerland in the late 2010s. Notably, recent acquisitions by Holcim that connect to its growing focus on CDW include Poland-based Ol-Trans in July 2022, UK-based Wiltshire Heavy Building Materials in October 2022 and UK-based Sivyer Logistics in April 2023.
As covered by Global Cement Weekly in February 2023, Holcim is not the only heavy building materials company pivoting to CDW. The European Union (EU) set a 70% recovery target for it in 2020 and various cement company sustainability reports have described the region as being receptive to moves into this sector. Cemex set up a global waste management subsidiary called Regenera at the end of January 2023. This division covers both alternative fuels, CDW and industrial by-products, so it is more general than Holcim’s current effort, but it shows intent in the same direction. Cemex previously set a target of recycling 14Mt/yr CDW by 2030.
Heidelberg Materials has been working on developing recycled concrete paste and its ReConcrete-360° concrete recycling process. As of its last sustainability report, this process had been tested at the pilot scale and is now being developed and scaled for industrial application. In addition to acquiring UK-based Mick George Group in December 2022 Heidelberg Materials has also purchased Germany-based RWG Holding in January 2023 and Germany-based SER Group in February 2023. All three companies operate in the CDW sector.
The other notable contribution that Heidelberg Materials has been making is as a partner of the ‘Circular City - Building Material Registry for the City of Heidelberg’ project. When Heidelberg Materials announced its involvement in the initiative in mid-2022 it said it was the first city in Europe to apply the principles of urban mining. The goal of the project is to take an inventory of the city’s buildings and then compile it in a digital material registry. The basis for the registry is the Urban Mining Screener developed by EPEA (Environmental Protection Encouragement Agency). This programme can estimate the composition of buildings based on building data such as location, year of construction, building volume or building type. Circular economy supply chains can then act accordingly when a building is retrofitted, demolished or deconstructed. So, for example, at the start of the project it worked out that a former US Army housing estate conversion site was calculated to contain approximately 466,000t of material, with about half in the form of concrete, a fifth in the form of bricks and 5% as metal.
That last example compares to a European Commission estimate that, as a whole, Europe generates around 450 - 500Mt/yr of CDW. A third of this is concrete. As with alternative fuels and slag previously, this may be money going into the ground. Recycling building materials is not new but any significant increase in reusing CDW that can reduce the clinker factor of cement (and the cement factor of concrete) offers a potentially cheaper route to building materials decarbonisation than carbon capture and utilisation/storage at current costs. Hence the continued interest.
Switzerland: Holcim has launched ECOCycle, its initiative to recycle construction demolition materials into new building products. It says it can recycle construction demolition materials across a broad range of applications, from decarbonised raw materials in low-carbon cement formulation, to aggregates in concrete and fillers in road construction.
Jan Jenisch, the chief executive officer of Holcim, said “Across all metropolitan areas where we operate, we are at the forefront of driving circular construction to build new from the old. With our ECOCycle technology we can build cities from cities, recycling 100% of construction demolition materials into new solutions, so everything gets reused and nothing gets lost. With our world’s growing population and urbanisation, circular construction is essential to build a future that works for people and the planet.”
The building materials producer is deploying its ECOCycle technology across its range of products to scale up circular construction. It says that its process enables concrete, cement and aggregates to contain from 10 - 100% recycled construction and demolition waste with no change in performance. The initiative is supported by distributing, processing, grinding and recycling construction and demolition materials into new building material products.
ECOCycle brings together previous work Holcim has conducted in the field such as launching a cement in Switzerland made with 20% demolition and construction waste. The company is now launching this product elsewhere in Europe. In France it is building an affordable housing complex using 100% ECOCycle recycled concrete. In the UK it is building a residential area with 50% ECOCycle aggregates that have been made from 100% recycled construction demolition materials.
