Saudi Arabia: Saudi Readymix and Finland-based Betolar have launched two new reduced-CO₂ concretes, produced using ground granulated blast furnace slag and natural pozzolans with Betolar’s Geoprime technology. One of the products is cement-free and the other has an ultra-low (2.5%) cement content. TradeArabia News has reported that the dual launch concludes a successful partnership between the companies, which began in 2023.

Saudi Readymix technology and strategy director Chris Leptokaridis said "Saudi Readymix has been at the forefront of developing new technologies to meet our customers' increasing demand for eco-friendly, low-CO₂ solutions. Our partnership with Betolar has enabled us to successfully deliver on this goal, offering groundbreaking concrete recipes that significantly reduce carbon emissions."

Betolar senior researcher Ahmad Alzaza said "This project pushed the boundaries of innovation by bringing low-carbon technology into the ready-mix concrete space. We are proud to have contributed to a solution that will help advance sustainable construction across Saudi Arabia."

US: Novel concretes developer Greencraft has made a patent application for a new method of CO₂ mineralisation using a microporous material containing mineral oxides, like slag. Global Warming Focus News has reported that the method also works for natural hyaloclastite, bottom ash, fly ash, volcanic ash and lava.

Greencraft said that its method marks an ‘improvement’ in current techniques for sequestering CO₂ in alternative materials.

UK: Switzerland-based Neustark has partnered with Holcim subsidiary Aggregate Industries to launch the UK’s first mineralisation plant in Greenwich, London. The small-scale mobile plant will sequester CO₂ in recycled concrete produced using fines recovered from construction and demolition materials (CDM). The plant is situated at an existing Aggregates Industries CDM recycling site. A large-scale plant with a sequestration capacity of 1000t/yr of CO₂ is due to follow in early 2025.

Neustark CEO Valentin Gutknecht said "Neustark and Holcim have been working together almost since the founding of Neustark five years ago. 1Mt of CO₂ durably removed from the atmosphere in 2030 – that’s our ambition. We’re already well underway towards the megatonne goal. Our strategic partnership with Holcim represents a significant part of this roadmap. It will be a true catalyst to further scale up the permanent carbon removal impact that we generate in the next few years.”

Aggregate Industries CEO Lee Sleight said that the partnership would turn London into ‘one of the world’s largest urban mines.’ He said “This isn’t just a great carbon removal innovation but a great circular economy innovation, where we are taking what was once a waste stream and reusing it, saving us from digging up virgin materials in the first place."

Neustark has so far sequestered 2500t of CO₂ in circular concrete for use in further construction.

South Africa: Raubex recorded sales of US$617m in the first half of the 2025 financial year, following ‘strong performances’ across all divisions. This corresponds to a 30% year-on-year rise. Operating profit also grew, by 35%, to US$47.7m.

Raubex’s gypsum, concrete and aggregates subsidiary OMV performed ‘well,’ according to the parent company. It attributed the performance to a growth in the local construction industry.
