UK: The UK government has committed to investments worth Euro22.8bn in early deployments of carbon capture technology. It will announce a shortlist of new projects for deployment later in March 2022.

The government said "This unprecedented level of funding for the sector will unlock private investment and job creation across the UK, particularly on the east coast and in the North West of England and North Wales. It will also kick-start the delivery of subsequent phases of this new sustainable industry in the UK."

Ireland-based Ecocem responded to the budget with a call for funding for more short-term areas besides carbon capture. It said these will be essential in order for the UK cement and concrete industry to reach its 45% decarbonisation target by 2030. The slag-based cement products company called for funding for low-clinker technologies which have already been developed and can be rolled out at scale before 2030, until carbon capture becomes a 'scalable, viable option.'

Canada: The city administration of Langford in British Columbia plans to enact regulations requiring all public and private projects to use reduced-CO₂ concrete. It plans to support the rules with parallel measures affecting the design of buildings.

Victoria News has reported that the city authorities previously mandated reduced-CO₂ cement for all projects in June 2022, but subsequently relaxed the regulations after only one company – Butler Concrete and Aggregates – completed the transition. Butler Concrete and Aggregates produces its reduced-CO₂ concrete using slag cement supplied by Lafarge Canada.

Croatia: Nexe has awarded a contract to Germany-based ThyssenKrupp Industrial Solutions for the construction of a new clinker line and carbon capture installation at its 0.6Mt/yr Nasice cement plant. The Poslovni Dnevnik newspaper has reported that the work will cost Euro400m. When commissioned in 2029, the upgraded plant will produce carbon neutral cement and despatch 700,000t/yr of CO₂ by pipeline for storage near Bockovac in Osijek-Baranja County.

Mexico: Cemex has made an issue of US$1bn-worth of notes without a maturity date. The producer says that the proceeds will fund its green initiatives.

Cemex said "Eligible green projects include capital, operating and research and development expenditures related to pollution prevention and control, renewable energy, energy efficiency, clean transportation, sustainable water and wastewater management and eco-efficient and/or circular economy-adapted products, production technologies and processes.”

UK: The Global Cement & Concrete Association (GCCA) held an online launch for its second Innovandi Open Challenge on 14 March 2023. The global challenge matches start-up companies with some of the world’s leading cement and concrete manufacturers, which operate in almost every country across the world, to work on initiatives to cut emissions and pioneer environmental change across the industry. The launch follows the success of the first ever Innovandi Open Challenge in 2022, which saw cement companies partnering with six start-ups, with a strong focus on carbon capture and utilisation projects.

This time around, applicants are being asked to work on the development of new materials and ingredients for low carbon concrete – a major step towards the goal of net zero concrete. Alternative materials, including construction and demolition waste, can result in far lower CO2 emissions than traditional concrete, as well as reduce the need to use virgin raw materials. The applications phase will last until mid-May 2023.

Thomas Guillot, CEO of the GCCA, said “We’re calling on the best and the brightest from around the world to join us in the urgent fight to limit global warming and help towards delivering the great prize of net zero concrete. If you are a start-up from Austria to Australia, from Brazil to Bangladesh, with an innovative idea or technology, then we want to hear from you.”

Those companies that are accepted for this year’s Innovandi Open Challenge will gain unique access to industry plants, laboratories, key networks and the expertise and infrastructure of the GCCA’s 40 members from around the world. They will also receive guidance from the GCCA and its members to help them with the development of new technology and business cases.

Claude Loréa, GCCA cement director and innovation lead, said “We’ve already seen some remarkable progress from those start-ups who’ve been working with our members on the first Innovandi Open Challenge, with several projects already in the pilot stage. This year’s theme, low carbon concrete, is equally challenging. To succeed, we need products which are affordable, scalable and easily adopted. Good luck to all this year’s applicants. We look forward to working with those selected.”

US: Buzzi Unicem subsidiary Alamo Cement Company has successfully commissioned its new 17,800MWh solar power plant at its San Antonio cement plant in Texas. The producer says that the facility will eliminate 8000t/yr-worth of CO₂ emissions from the plant's operations. It spans an area of 18.2 hectares at the site of the 1.1Mt/yr cement plant. Texas-based energy provider CPS Energy built the installation.

Alamo Cement's director of engineering and construction management William Kovacs said "I am incredibly proud of the multi-discipline work that went into this first-of-its-kind project for Alamo Cement in San Antonio. It is an example of the type of collaboration necessary to continue to unlock and apply new energy sources for cement producers. It was a collective effort that brought together our corporate team, CPS Energy and regional engineering firms and contractors."

El Salvador: Holcim El Salvador says that the upcoming solar power plant at its El Ronco cement plant will have a capacity of 21.4MW, across three separate installations. Energy provider AES El Salvador holds a 20-year power supply agreement for construction and operation of the plant. The La Prensa Grafica newspaper has reported that Banco Cuscatlán supplied a loan for the project. When operational, the new solar power plant will lower Holcim El Salvador's oil consumption by 43,000 barrels/yr.

Holcim El Salvador CEO Rodrigo Gallardo said "We are not only making solutions and products with a lower CO₂ content, but also cutting CO₂ in our production processes."

US: SLB has launched EcoShield, a geopolymer-based well cement product. The company, also known as Schlumberger, says that the product cuts out up to 85% of embodied CO₂ emissions compared with conventional well cementing systems because it does not use ordinary Portland cement (OPC). It also reduces transport related emissions by using locally-sourced natural materials and industrial waste streams in its composition. The company says that the cement-free system can be deployed throughout various phases of the well life cycle, including abandonment. It can also be deployed across a range of field applications, including corrosive environments.

Jesus Lamas, SLB’s president of Well Construction, said “Decarbonising the well construction process while ensuring safety and performance standards is critical to our industry’s pathway to net zero.” He added “The cement-free EcoShield system is a breakthrough that delivers industry-standard zonal isolation capabilities while significantly minimising impacts from upstream oil and gas production.”

EcoShield has been tested by Pioneer Natural Resources in the Permian Basin on an 18-well field testing campaign and its use is ongoing.

Canada: Progressive Planet is preparing to build a 3200t/yr pilot plant for its PozGlass product at its headquarters in Kamloops, British Columbia. The company aims to commercialise its process, which produces pozzolan from recycled glass for use in cement or concrete production. The pilot unit will also sequester CO₂ released by a gas dryer at the site, from which it will produce sodium carbonate. The pilot plant is expected to go under construction in 2023 and be operational in 2024.

Steve Harpur, the chief executive officer of Progressive Planet, said “With PozGlass, a CleanTech breakthrough from our C-Quester Centre of Sustainable Innovation in Kamloops, we are producing one of many upcoming private-sector solutions that are needed to meet the 2050 Net Zero targets to fight climate change.”

Progressive Planet aims for PozGlass production to be situated at cement kilns, where PozGlass could be mixed with Portland cement at a 50:50 ratio.

France: CRH subsidiary Eqiom expects to complete its carbon capture system installation and kiln upgrade at its Lumbres cement plant under the EU's K6 Programme in early 2028. The project uses Air Liquide's capture technology, whereby purified CO₂ is liquefied for storage or use in building materials production.
