France: Hoffmann Green Cement Technologies has announced the launch of H-CLAY, a new technology that enables the cold processing of clay into a co-product for use in the formulation of 0%-clinker cements. This technology is based on a process for cold-processing clay, without resorting to traditional calcination or flash-calcination processes and their associated CO₂ emissions. H-CLAY enables the recovery of various types of clay to be integrated as a co-product in the formulation of low-carbon cements, similar to slag in some of the company’s 0%-clinker cements.

Julien Blanchard and David Hoffmann, co-founders of Hoffmann Green Cement Technologies, said "The launch of H-CLAY marks a new milestone in Hoffmann Green's technological history. Having demonstrated that it is possible to mass produce and market high-performance clinker-free cements, we are now breaking new ground with the cold processing of clay, without calcination or flash-setting. This innovation perfectly illustrates our ambition: to develop disruptive technologies able to significantly reduce cement's carbon footprint, while meeting the technical requirements of the construction market.”

Germany: The FEhS Building Materials Institute has published a report on the Save CO₂ project investigating the suitability of electric hot metal slag (EHMS) from hydrogen-based direct reduction steelmaking for use in cement production. The project aims to establish whether EHMS might replace conventional ground granulated blast furnace slag. Laboratory and large-scale trials showed that EHMS achieves glass contents close to 100% and achieved comparable 91-day compressive strengths to ordinary Portland cement (OPC) and other slag cements in a 50% blend. Lifecycle assessments indicated a 35% reduction in CO₂ emissions, subject to renewable energy supply. The German Federal Ministry of Research, Technology and Space funded the research.

FEhS Building Materials Institute says that the next steps will be to secure REACH registration and standardisation, ahead of eventually building a large-scale plant at a Thyssenkrupp Steel Europe site.

Argentina: Total cement despatches in Argentina fell by 2% year-on-year to 810,000t in May 2026, and accumulated despatches in the first five months of 2026 fell by 3% year-on-year to 3.87Mt. Domestic despatches fell by 1% year-on-year to 807,000t in May 2026, while exports fell to 3083t from 4809t in May 2025. Total cement consumption fell by 1% year-on-year to 807,000t in May 2026, with accumulated consumption in the first five months of 2026 down by 3% year-on-year to 3.85Mt. Imports fell to 179t in May 2026 from 62t in May 2025.

Turkmenistan: The upcoming state-owned 1Mt/yr Baharden II cement plant in Ahal Region is on track for commissioning later in 2026, the State News Agency of Turkmenistan has reported.

President of Turkmenistan Serdar Berdimuhamedov said "I am firmly confident that the industrialists of our independent, neutral fatherland will continue to work selflessly in the future to transform the country into an ever more developed state, uninterruptedly supplying construction sites and the population with high-quality construction products, making a worthy contribution to strengthening the potential of the national economy."

The existing 1Mt/yr Baharden I cement plant doubled its six-month cement production year-on-year in 2026-to-date, to 419,000t.
