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.
