Heidelberg Materials UK is trialling CarbonCure technology in ready-mixed concrete at its Greenwich plant in London, injecting pure manufactured CO₂ into fresh concrete where it mineralises permanently and allows around 5% less cement to be used. The process is claimed to cut concrete-associated emissions by 7–11 kg CO₂/m³ with no loss of performance, while potentially increasing strength through more efficient hydration. The Thameside plant also supplies calcined clay, evoBuild low carbon GGBS, crushed concrete, accelerators and evoZero near‑zero cement, positioning it as a low‑carbon materials hub.

Latrobe Magnesium has produced its first sustainable magnesium oxide at a demonstration plant in Hazelwood North, Victoria, using proprietary technology to extract magnesium from Latrobe Valley brown coal fly ash. The process targets commercial production of both magnesium metal and supplementary cementitious material (SCM)-grade by-products, aiming to replace imported magnesia and reduce cement clinker content. For geotechnical and concrete practitioners, locally sourced MgO and SCM from waste ash could alter binder specifications, shrinkage control strategies, and durability mix designs in eastern Australia.

Use of calcined clay concrete on the London Museum project, led by Sir Robert McAlpine with close input from engineers, contractors and materials suppliers, is enabling on-site deployment of a lower-clinker, lower-carbon mix rather than limiting it to precast elements. The team is adapting mix design and placing methods in real time on a live heritage-site build, addressing workability, setting time and strength-gain behaviour under typical UK site conditions. For practitioners, this signals growing confidence in calcined clay binders for mainstream structural applications where conventional CEM I would previously have been specified.
