Germany: Holcim Deutschland has commenced a carbon capture trial at its 950,000t/yr Beckum cement plant in Beckum-Kollenbach, North Rhine-Westphalia. The trial will employ amine scrubbing technology to separate CO₂, which it will then seek to commercialise for other industrial uses. Holcim Deutschland's partners for the project are Technische Universität Berlin and construction engineering firm thyssenkrupp Uhde. The trial also has funding from the German government.

Italy: Italcementi, part of Heidelberg Materials, has filed a patent application for a titanium dioxide-based cementitious material. The Patent Office Journal has reported that the material consists of titanium dioxide (TiO2) imbued with carbon dopants. This is produced by irradiating the TiO₂ in the presence of an inert gas and an organic compound.

UAE: Holcim subsidiary Lafarge Emirates Cement (LEC) has begun construction of a 10MW waste heat recovery (WHR) plant at its 3.2Mt/yr Fujairah cement plant. Supplier Engie Solutions says that it expects to commission the installation later in 2023. Trade Arabia News has reported that the equipment is based on a closed-loop organic Rankine cycle and will eliminate 29,000t/yr of CO₂ - 28% of the Fujairah cement plant's energy-related CO₂ emissions.

LEC general manager Olivier Milhaud said "Engie’s energy-as-a-service model means guaranteed energy savings and higher reliability and resilience, with no capital outlay and no need for additional staff." He continued "We are fully committed to the UAE’s sustainability goals, including the 2050 Net Zero vision."

France: The French cement association France Ciment has announced a new CO₂ emissions reduction target of 50% across the cement industry between 2021 and 2030. The new target for 2050 will be 'virtual carbon neutrality.' The Les Echos newspaper has reported that the commitments replace previous reduction targets of 24% by 2030 and 80% by 2050. France Ciment says that its members are planning estimated investments of Euro5bn towards achieving the goals before 2040. These investments will cover areas including the deployment of carbon capture. Existing public and private investments in the industry's on-going projects to reduce CO₂ emissions amount to Euro1.7bn - sufficient to eliminate 27% of emissions compared with the 2021 baseline.

France Ciment’s President Benoit Pillon noted the necessity of cement in construction, and called for 'decarbonisation as a whole: less clinker in cement, less cement in concrete and less concrete in construction.' He urged the implementation of policies to secure 'decarbonised and competitive electricity.'

Germany: Chemicals company BASF has won a contract to supply its OASE Blue CO₂ separation technology for use in the upcoming 70,000t/yr carbon capture installation at Heidelberg Material's Lengfurt cement plant in Bavaria. The Capture to Use (Cap2U) project, in partnership with fellow chemicals company Linde, aims to capture CO₂ from the plant for use in the chemicals, food and beverages industries.

BASF head of gas treatment Andreas Northemann said “Our portfolio of OASE technologies makes a significant contribution to sustainability and is perfectly suited to help our customers achieve their sustainability targets. This carbon capture and use unit facility has the potential to become a show-case project in a hard-to-abate sector."

Canada: A study led by Douglas Geoffrey in Calgary, Alberta, has patented a method of producing cement from calcium carbonate precipitated in the carbonation of brine. The method mixes the mineral with magnesium oxide and cures it to form cement.

Geoffrey noted that the brine may derive from multiple industrial processes, including fossil fuel and potash production, geothermal power generation and desalination.

Europe: Holcim plans to deploy 1000 new electric trucks in its operations across Europe before 2030. The cement producer ordered the vehicles from Sweden-based Volvo. Both companies are founding members of the First Movers Coalition low-CO₂ technology alliance. Holcim expects the initiative to reduce its annual CO₂ emissions from road transport by 50%. It will take delivery of the first new trucks by the end of 2023.

Chair and CEO Jan Jenisch said “The net zero transition requires deep collaboration across value chains. We are excited to be partnering with Volvo to decarbonise our European operations’ logistics with electric fleets, advancing our goal to reach 30% of zero-emission heavy-duty trucks by 2030.”

World: The Global Cement and Concrete Association (GCCA) has received over 70 submissions to its Innovandi Open Challenge 2023, and is now preparing the shortlist of startups to present their pitches on 30 June 2023. The Innovandi Open Challenge seeks new disruptive technologies to help to achieve net zero cement and concrete production by 2050. Startups selected under the challenge will have the opportunity to partner with the GCCA and its members to further develop their products.

GCCA cement director and innovation lead Claude Loréa said “To receive more than 70 quality applications from start-ups for this year’s Innovandi Open Challenge is hugely encouraging, and shows what level of interest and work is being done to help drive climate action, with applications received from every region of the world." She concluded "Our vital industry needs products which are affordable, scalable and easily adopted. We look forward to sifting through the applications with our member companies and working with those who are selected.”

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.
