EU: Cembureau, the European cement sector association, has lobbied the EU in support of a draft act for the setting of CO₂ storage capacity quotas for member states. It called for the simplification and acceleration of permitting procedures for storage sites. It also encouraged policymakers to strengthen the focus on CO₂ transport networks, ensuring fair access conditions for cement plants.

Cembureau said "Whilst a mix of technologies are needed to decarbonise cement production, carbon capture, utilisation and storage (CCUS) is particularly critical, as our sector faces unavoidable process emissions. A large number of CCUS pilot and demonstration projects have been launched by cement companies across Europe, with the first of them becoming operational as early as 2024. The pipeline of investments is particularly strong – for instance, the latest ETS Innovation Fund call awarded over Euro500m three cement CCUS projects."

Germany: Solid UNIT Germany, the German construction sector association, has launched its climate advisory board. The board will advise on and jointly instigate initiatives together with the Solid UNIT Germany management board. Its membership comprises representatives from the German Sustainable Building Council (DGNB), the Institute for Sustainable Construction in Germany (ARGE) and the Federal Chamber of Architects, along with members of parliament.

Solid UNIT Germany managing director Thomas Zawalski said "To cope with the Herculean task ahead of us, it is important to bundle experience. Faster CO₂ reduction in the building sector is only possible through joint action by all stakeholders."

US: Holcim US has appointed TotalEnergies to install, maintain and operate a 33MW solar power plant and 38.5MWh battery system at its Florence, Colorado cement plant. By storing energy with the battery system, the plant can relieve demand on the grid at peak times. Holcim will receive roughly 71,000MWh/yr of renewable energy under a minimum 15-year power purchase and storage services agreement (PPSSA). The partners expect the new systems to reduce the plant's CO₂ emissions by 40,000t/yr and its energy consumption by 40%.

Holcim North America’s vice president for procurement Atl Martinez said "As we work to accelerate green growth across the US, it's critical that we come to the table with partners who share similar goals around circularity and renewable energy. This initiative with TotalEnergies demonstrates an ongoing determination to transform our operations and lower our carbon footprint. It's a milestone investment that will decrease our reliance on other sources of energy and shrink our utility costs through a powerful combination of clean energy and efficient operations."

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.

France: Estelle Bletry has taken on the role of sales manager for Holcim’s waste management subsidiary Geocycle. Bletry held different positions in Lafarge France between 2007 and 2019. She worked as product development manager and business developer materials and solutions at waste management company Hesus from 2019 to March 2023. Bletry studied marketing at IUT Cergy-Pontoise in Paris.

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."
