France: Germany-based Heidelberg Materials announced a planned Euro65m upgrade to its Bussac-Forêt cement plant in Charente-Maritime Department on 14 May 2023. The project will involve the installation of systems for the production of calcined clay cement. The producer says that this will enable the 0.8Mt/yr plant to reduce its CO₂ emissions by 20%.

Chief sustainability officer Nicola Kimm said “In Bussac-Forêt, we are investing in a technology with great potential. It will allow us to significantly expand the range of low-carbon products. Using calcined clay as a clinker substitute is an important measure to reduce the carbon footprint of cement and concrete. In principle, a CO₂ reduction of up to 40% is possible when substituting cement clinker with calcined clay.”

Heidelberg Materials is already involved in the on-going pilot trial of a 400,000t/yr clay calcination plant in Ghana.

France: Hoffmann Green Cement Technologies has commissioned its H2 plant, a 1000t/day clinker-free cement plant, adjacent to its existing H1 clinker-free cement plant in Bournezeau, Pays de la Loire. L'Usine Nouvelle News has reported that the new plant took 24 months to build and cost Euro22m. The main part of the plant consists of a 70m tower, where activated clay, ground granulated blast furnace slag (GGBFS) and gypsum are mixed to produce the cement. It is installed with solar panels capable of supplying 50% of its energy consumption. The producer says that its clinker-free cement has over 90% lower CO₂ emissions than cement produced with ordinary Portland cement (OPC). It aims to sell 24,000t of the product throughout 2023.

Canada: Lafarge Canada has renewed its partnership with fuel logistics company 4Refuel to launch renewable diesel use in its operations in Manitoba. The producer says that trucks will run on renewable diesel produced from waste oils and fats. This will eliminate 39% of the producer's Scope 3 CO₂ emissions in the province.

Lafarge Canada's vice president Manitoba and Saskatchewan Tina Larson said "Switching to renewable diesel is a significant step forward in our sustainability journey. We recognise that climate change is one of the most significant challenges facing our planet, and we are committed to doing our part to reduce our impact on the environment. We believe that renewable diesel is an excellent solution to help us achieve our sustainability goals while maintaining the high level of performance that our customers expect.”

Lafarge Canada previously implemented renewable diesel in its operations in Greater Vancouver, British Columbia, in November 2022.

Argentina: Cementos Avellaneda has signed a memorandum of understanding (MoU) with energy provider YPF Luz for the construction of a new wind farm. Local press has reported that the planned plant will have a capacity of 63MW and be situated in Olavarría, Buenos Aires Province. There, it will supply 100% of the energy used in cement production at Cementos Avellaneda's Olavarría cement plant. The cement producer will transmit any surplus energy from the wind farm to its San Luis plant at La Calera, with the longer-term aim of becoming Argentina's first 100% renewably-powered cement company.

The partners will carry out technical and economic feasibility studies in mid-2023, and publish plans and budget before the end 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.”

Canada: The Cement Association of Canada (CAC), with its members and partners in the concrete sector, has released Concrete Zero, an action plan to help the local cement and concrete sector reach net-zero CO₂ emissions by 2050. The five priority areas it is focusing on include: eliminating the use of coal and petroleum coke as fuel sources for clinker production; reducing the volume of clinker used to produce cement; increasing the use of supplementary cementitious materials; working towards building carbon capture, utilisation and storage capacity; and advocating for performance-based codes, standards and specifications, procurement policies and increased material efficiency in construction. Targets include reaching a 100% fuel mix from non-fossil-based sources by 2050. The latest plant follows the goal of achieving a 40% emissions reduction by 2030 as part of its Roadmap to Net-Zero Carbon Concrete by 2050.

Adam Auer, the president and chief executive officer of CAC, said “Our net-zero action plan is ambitious and cannot be achieved by industry action alone. Working with government, industry, and partners in the design, architecture, and construction industry will be essential for success. Canada’s cement and concrete industry are committed to doing our part to help Canada build a better, cleaner future. Working together, we can deliver Concrete Zero.”

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.
