US: Brimstone has announced a new method of ordinary Portland cement (OPC) with a negative carbon footprint. Brimstone's method uses carbon-free calcium silicate in the place of limestone. Its calcination also produces magnesium compounds, which naturally sequester further CO₂ from the atmosphere. The technology will now proceed to the testing phase at an upcoming pilot plant in Reno, Nevada, before proceeding to commercial-scale production. Brimstone will then begin to market its OPC, along with supplementary cementitious materials produced by its process.

Brimstone's chief technology officer Hugo Leandri said “By delivering the exact same cement, we clear away the main obstacles to adoption, offering an opportunity to dramatically speed up the path to net-zero construction. The same buildings, bridges and roads being built today can be built tomorrow, without carbon."

China: Asia Cement has launched its 2050 decarbonisation strategy, entitled 'Net-Zero Carbon Emissions By 2050 - Asia Cement Advanced Deployment.' The strategy consists of multiple pillars, namely 'alternative fuels,' 'reducing cement's clinker factor,' 'increasing renewable energy reliance' and 'carbon capture.'

During 2022, Asia Cement reduced its limestone, clay, iron and sand consumption by 266,000t, its coal consumption by 17,000t and its gypsum consumption by 56,000t year-on-year. This eliminated 95,100t of CO₂ emissions throughout the year, according to the producer.

Peru: UNACEM Peru said that it reduced its CO₂ emissions per tonne of cement by 2.7% year-on-year during 2022. Throughout the year, the company reduced its electricity consumption by 3.4%. It sourced 90% of its electricity from renewable sources and met 70% of its fuel needs with natural gas. UNACEM Peru is committed to reaching carbon neutral cement production by 2050.

In terms of community engagement, the producer benefitted 76,700 people through its social infrastructure investments and 14,1000 people through its dialogue space initiatives, and provided its remote health guidance service to 3000 people.

World: The Global Cement and Concrete Association (GCCA) has named the 15 anticipated deliverers of low-CO₂ cement and concrete production shortlisted for participation in its second Innovandi Open Challenge. The association chose the start-ups based on their potential to deliver CO₂ emissions reduction in the global cement and concrete sector in line with its Concrete Future 2050 Net Zero Roadmap. The applicants are presenting their pitches to GCCA members on 30 June 2023. All those accepted will gain access to members' plants, labs, networks and expertise. The following start-ups made the Innovandi Open Challenge 2023 shortlist:

GCCA cement director and innovation lead Claude Loréa said “We received more than 70 quality applications, so drawing up a shortlist was challenging." Loréa continued "Our essential industry needs something easily scalable and affordable. Those start-ups on the list demonstrated the most potential, and we look forward to hearing more about their ideas. But we’ll also be keeping in touch with other start-ups who didn’t make this year’s shortlist, with future projects in mind.”

Spain: Cemex España has secured Euro4.4m in EU funding for an upgrade to its Alicante cement plant in Valencia. The project will launch the use of Clyngas synthetic gas as alternative fuel (AF) at the plant. Thermochemical conversion specialist WtEnergy, a subsidiary of Cemex Ventures, will supply the syngas. The partners say that this upgrade will reduce CO₂ emissions by 400,000t per decade.

Parent company Cemex said "This project is part of Cemex’s Future in Action programme, which seeks to achieve sustainable excellence through climate action, circularity and natural resource management, with the primary objective of becoming a net-zero CO₂ company."

France: Lafarge France has signed a memorandum of understanding with green hydrocarbons specialist Axens, utilities provider EDF and research firm IFP Energies Nouvelles for a synthetic fuel production trial. The partners will build a plant to produce kerosene using captured CO₂ from a carbon capture installation at Lafarge France's Saint-Pierre-La-Cour cement plant. The project, called Take Kair, aims to produce fuel for use by aviation companies, including Air France-KLM Group.

Holcim France president François Petry said "The decarbonisation of our processes and products is at the heart of our strategic commitment to reach Net Zero by 2050. Beyond the modernisation of our production tools, we work on all industrial and technological levers to reduce our emissions, and thus decarbonise our industry. With the Take Kair project, we are taking a decisive step in the capture and management of our residual CO₂ emissions and participate with our partners in the emergence of an innovative and sustainable sector serving the country's mobility needs."

Lafarge France, a subsidiary of Switzerland-based Holcim, announced a Euro40m investment in the 1.6Mt/yr Saint-Pierre-La-Cour cement plant to achieve carbon neutral cement production there in March 2022.

UK: Mineral Products Association Lime (MPA Lime), the body representing the UK lime sector, has launched the Net Negative 2040 Roadmap. The association said that the roadmap sets out the strategy for its to 'go beyond net zero' by 2040. The industry will rely on the deployment of fuel switching, carbon capture, renewable energy sources and green transport technologies, among other approaches. It called on the government to support its aims through the implementation of carbon accounting, subsidisation of renewables and decarbonisation technologies, the development of green hydrogen infrastructure, ensuring that UK lime can remain competitive in the UK and overseas markets.

MPA Lime director Mike Haynes said “Each lever will contribute to decarbonisation – many initiatives are happening already or will come on stream this decade." He added "The combination of using biomass fuels with carbon capture and lime product carbonation will result in removal of 250,000t/yr of atmospheric CO₂, making the sector net negative overall. Other levers, especially indirect emissions and transportation, require broader collaboration and enabling action by government and other industries.”

Through their actions to date, MPA Lime members reduced their absolute CO₂ emissions by 25% between 2005 and 2022.

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.

Denmark: Aalborg Portland and US-based Fidelis New Energy have signed a letter of intent to collaborate on the onshore storage of captured CO₂ from the cement producer's Aalborg cement plant in North Jutland. The partners will convey captured CO₂ from the plant to Fidelis New Energy's upcoming Norne Carbon Storage Hub at East Port of Aalborg via a pipeline. The pipeline is scheduled for commissioning ahead of the launch of the Aalborg cement plant's upcoming carbon capture system in 2030. The system will capture 400,000t/yr of CO₂ from the plant's flue gases.

Fidelis New Energy's Norne Carbon Storage Hub is due to commence operations in 2026. It will have a handling capacity of 4Mt/yr of CO₂, with the possibility of subsequently expanding to 8Mt/yr.

UK: CRH subsidiary Tarmac has pledged its support to the Route to Net Zero initiative to decarbonise the UK's logistics sector. Under the initiative, companies involved in transportation will implement changes aimed at achieving net zero CO₂ emissions by 2050. Tarmac already transports 9Mt/yr of materials around the UK by rail.

Tarmac's logistics director Graham Waters said “Signing up to Logistics UK’s Route to Net Zero pledge marks a further step for our business, underscoring our commitment to eliminating carbon emissions from our extensive UK-wide logistics networks and accelerating this process through collaboration with our haulier partners and the wider industry."
