UK: Breedon Cement commenced a 24-hour trial of graphene-enhanced cement production at its Hope Cement plant in Derbyshire on 28 June 2023. The trial advances the work of a consortium led by Australia-based First Graphene. It is using existing grinding aid dosage lines, with minimal adjustment required. Breedon Cement and its partners aim to produce 2000t of graphene-enhanced cement, using 1.2t of PureGRAPH 50. Graphene-Info News has reported that Breedon Cement will supply concrete produced under the trial to Morgan Sindall Construction for use in its building projects. The University of Manchester is also participating in the consortium.

Breedon Cement managing director Jude Lagan said “The role graphene can play in helping to decarbonise the cement industry could be significant, and we are keen to contribute to this process by facilitating what is set to be one of the largest global trials of this kind.”

Sweden: Nordkalk has produced lime at its Koping lime plant using 30% biofuel as alternative fuel (AF). The producer now aims to increase the substitution rate to 50%. Nordkalk subsidiary Kalkproduktion Storugns recently began trialling 100% liquid biofuel substitution in continuous operations at its Larbro lime plant. ENP Newswire has reported that both projects are part of a CO₂ emissions reduction initiative in partnership with the Swedish Energy Agency and Umea University.

US: Ash Grove Cement has won funding for a US$15.2m front-end engineering design (FEED) study for a carbon capture installation at its 2Mt/yr Foreman cement plant in Arkansas. Parent company CRH said that the study will run for 24 months from its date of commencement. The project team also includes consultancy and research firms Advanced Resources International and Crescent Resource Information, as well as non-profit interstate policy organisation Southern States Energy Board. Equipment suppliers will include France-based industrial gases company Air Liquide and energy company Sargent & Lundy, while electricity provider Talos will participate as an energy sector stakeholder.

The Foreman cement plant carbon capture FEED study is one of eight projects selected by the US Department of Energy to receive part of a US$189m funding pot for carbon capture demonstrations across US industry.

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.

US: Heidelberg Materials North America has secured funding for a feasibility study for a 2Mt/yr carbon capture installation at its Mitchell cement plant in Indiana. The study will also investigate possible storage and utilisation solutions for a future installation. The producer says that the US government's Department of Energy has pledged US$5m in funding towards the US$10m study.

Heidelberg Materials North America president and CEO Chris Ward said “We are pleased for this additional federal funding to help move our Mitchell carbon capture project forward. Heidelberg Materials recognises the significant role that carbon capture will play in achieving its goal of net zero carbon, and we are very excited to take the next steps in exploring this technology at our new cement plant in Mitchell.”

Finland: Finnsementti and energy provider St1 have selected Norway-based Aker Carbon Capture to carry out a pre-engineering study for a planned carbon capture system at the cement producer's Lappeenranta cement plant in South Karelia. Dow Jones Institutional News has reported that Aker Carbon Capture offers a 40,000t/yr carbon capture system, capable of producing 25,000t/yr of methanol for use as transport fuel. The project is scheduled to deliver commercial synthetic methanol by 2026.

The Lappeenranta cement plant carbon capture project recently received Euro35.4m in additional funding from the Finnish government, subject to European Commission approval.

Belgium: Heidelberg Materials has announced an upcoming project called Anthemis at its subsidiary CBR's Antoing cement plant in Hainaut. The project will implement Heidelberg Material's OxyCal model, which combines Oxyfuel and amine-based carbon capture technology. When operational, the system will capture 800,000t/yr of CO₂, reducing the Antoing cement plant's CO₂ footprint by 97%.

Heidelberg Materials chair Dominik von Achten said “We are excited to add yet another pioneering technology to our CCUS project portfolio, and to build on what we have already achieved in terms of research and innovation. From the Antoing plant alone, we will be able to offer more than 15Mt of carbon-free cement to the construction market during the first 10 years of operation." Von Achten concluded "This is a key contribution to Belgium’s transition to net zero greenhouse gas emissions.”

Israel: Cemex subsidiary ReadyMix Industries has placed a new order with transport safety technology supplier SaverOne 2014. The ready-mix concrete producer ordered a further 25 mobile phone control units for its truck fleet. The units are cloud-enabled and run off a mobile app which blocks drivers from using phones when their vehicle is in motion. The smart system can detect when a truck is stopped and differentiate between driver and passenger, enabling access when needed. Users can integrate their fleet's units with existing logistics management systems.

ReadyMix Industries completed a successful trial of SaverOne 2014's system earlier in 2022.

Mexico: Cemex has announced a raft of new carbon capture projects in Europe and North America. When commissioned, they will bring its total installed CO₂ capture capacity to over 3Mt/yr. The projects consist of three front-end engineering (FEED) studies to scale installations of Australia-based Leilac’s direct separation technology at Cemex cement plants in Germany, Poland and the US; a fourth FEED study for 95% capture installation at the Balcones, Texas, cement plant using RTI International's solvent capture technology and a development partnership for the cement industry's most comprehensive carbon capture, utilisation and storage (CCUS) studies at eight further cement plants in Europe, Mexico and the US.

Chief executive officer Fernando González said “CCUS brings together the essence of our strategic priorities: sustainability and innovation. Our Future in Action programme to achieve sustainable excellence and become a net-zero company is all about measurable, verified progress towards the most ambitious decarbonisation pathway in the industry. Although CCUS technologies are not ready to be scaled quite yet, it will take relentless work and innovation to ensure their viability in time to avoid the most damaging effects of climate change.”

India: Research by the Indian Institute of Technology – Madras (IIT Madras) has concluded that limestone calcined clay cement (LC3) production emits 40% less CO₂ than ordinary Portland cement (OPC) production, and is 20% less energy intensive. United News of India has reported that the Switzerland-based Swiss Agency for Development and Cooperation supported the study.
