US/Canada: Martin Marietta Materials signed a definitive agreement with Quikrete Holdings to exchange its Midlothian cement plant, related terminals and North Texas ready-mixed concrete assets for aggregates operations with a capacity of 20Mt/yr in Virginia, Missouri, Kansas and Vancouver, and US$450m in cash. The transaction is expected to close in the first quarter of 2026, subject to regulatory approvals.

Chair and CEO of Martin Marietta Ward Nye said “Following a thorough evaluation, we believe that exchanging our remaining cement plant and related ready-mixed concrete operations for core aggregates assets and pursuing accretive bolt-on acquisitions best positions the company for long-term earnings growth.”

US: Amazon and Brimstone have announced successful third-party test results for Brimstone’s lower-CO₂ ordinary Portland cement (OPC), which meets ASTM C150 requirements using Amazon slab mix designs. The companies will continue testing through 2025 and 2026. On the basis of the successful tests, Amazon has signed a commercial agreement to reserve annual volumes of OPC and supplementary cementitious materials from Brimstone’s upcoming plant in Oakland, California.

UK: Material Evolution has partnered with CRH subsidiary Tarmac to launch a pilot project to test applications of its heat-free, 85% reduced-CO₂ cement, MevoCem. The partners aim to demonstrate the suitability of MevoCem cement for use in concrete production in line with the prospective BSI Flex 350 performance-based standard.

Material Evolution’s CEO Liz Gilligan welcomed Tarmac as an ‘early adopter’ of MevoCem cement. In a post to LinkedIn, she said “We have been quietly building something game-changing with CRH and their team at Tarmac. It is bold, it is industrial scale and it is all about cutting carbon where it counts. We are only just getting started.”

Material Evolution currently operates a 120,000t/yr Mevocem plant in Wrexham, Wales.

Canada: Concrete carbon capture technology producer CarbonCure Technologies has appointed Kristal Kaye as Interim CEO. Kaye previously served as the company’s Chief Financial Officer and, in that capacity, has already been deeply engaged with CarbonCure’s team, strategy and day-to-day operations. Her appointment comes as CarbonCure’s founder, Robert Niven, steps away from the CEO role. Niven will remain a strong supporter of CarbonCure, continuing to serve on the company’s Board of Directors.

Under Niven’s leadership, CarbonCure developed and commercialised the most widely-deployed carbon utilisation solution for lower-carbon concrete manufacturing. Over the past decade, CarbonCure has licensed hundreds of its CO2 injection systems to concrete producers across more than 20 countries, permanently mineralising and reducing nearly 0.6Mt of CO₂.

“Everyone at CarbonCure feels deep gratitude to Rob for his pioneering carbon utilisation innovation for lower carbon concrete and his tireless dedication to CarbonCure over the past 13 years, with many years of research and development before that,” said Kaye. “Stepping into this interim role, I am eager to carry Rob’s legacy forward, and our entire team remains committed to that mission, our core values and the success of our concrete producer partners around the world.”

Europe: Heidelberg Materials and environment consultancy Arup have signed a memorandum of understanding (MoU) to collaborate on decarbonisation of the built environment through carbon capture and storage-enabled cement and concrete.

The partners will conduct joint research and technical analysis on the deployment of CCS technologies across cement and concrete production. Heidelberg Materials and Arup previously began collaborating in November 2024 to assess the benefits and feasibility of carbon-captured cement and concrete.

Global: The Global Cement and Concrete Association (GCCA) has launched the Low Carbon Ratings (LCR) system for cement and concrete, a new global rating based on products' carbon footprints. The system uses a clear AA to G scale to help customers prioritise sustainability in material selection across construction sectors worldwide.

The GCCA says that the LCR system is designed to be easily recognisable, with a simple visual graphic that indicates a product’s rating and provides consistency and comparability to other products. Countries will be able to adapt the system according to local standards.

Sweden: Cemvision and S:t Eriks have entered into a partnership agreement as a result of several pilot projects using Cemvision’s cement in S:t Eriks’ production. The partners have signed a letter of intent to develop and implement sustainable concrete solutions within water and sewage infrastructure. Having already tested Cemvision’s cement in its own production, S:t Eriks will then implement the cement in commercial projects. The product reportedly offers high resistance to sulphate and acid attacks, which contribute to longer service life.

In the coming months, Cemvision and S:t Eriks will continue testing to explore the potential for broader implementation of the cement in water and sewage systems.

Poland: Cemex has signed an agreement with EDP Energia Poland to build solar installations at several of its sites, with a total capacity of over 14MW. The investment is part of its ‘Future in Action’ strategy to combat climate change.

New solar plants will be installed at Cemex's cement plants in Chełm, Rudniki, and Gdynia, as well as its ready-mix concrete plants in Mysłowice, Warsaw Annopol, Lublin, Szczecin, and Gdańsk. The concrete plant installations will begin operating in the second quarter of 2025, while the installations at the cement plants are scheduled to start generating power in the first quarter of 2026. EDP Energia Polska will install and manage the solar installations under a 15-year agreement, supplying renewable energy to Cemex facilities.

Sweden: Swedish cement manufacturer Cemvision has entered a strategic partnership with Norway-based residential developer JM to develop ‘climate-friendly’ cement and concrete. As part of the agreement, JM has also acquired a minority stake in Cemvision.

Cemvision’s cement reportedly reduces CO₂ emissions by up to 95% compared to traditional cement, through the use of recycled industrial waste from mining and steel industries, combined with renewable energy in its kiln operations.

India: Mahabal Cement has signed a memorandum of understanding (MoU) for a US$1.26bn investment at the Advantage Assam summit.

The investment will have several phases. The first phase will be the construction of an integrated cement plant in Assam's Dima Hasao district, followed by a ready-mix concrete plant, which will produce autoclaved aerated concrete blocks. More than 3000 jobs will reportedly be created through the investment.
