Tokamak Energy has completed a 14‑month test campaign on Demo4, its high‑temperature superconducting (HTS) magnet testbed in Oxford, aimed at validating magnet performance for compact spherical tokamak fusion reactors. The Demo4 system is designed to operate HTS coils at cryogenic temperatures while subjecting them to high magnetic fields and mechanical loads representative of reactor conditions, a critical step for future fusion power plant infrastructure. Results will inform structural design, thermal management and lifecycle performance of full‑scale HTS magnet assemblies for grid‑scale fusion demonstrators.

Metso distributor McHale Plant Sales is taking orders in the UK and Ireland for two new Lokotrack units – the 70‑tonne LT400RS diesel‑electric mobile impact crusher and the LT200HPX mobile cone crusher with integrated screening – with deliveries from early 2025. The LT400RS, built around a 250 kW Nordberg NP1213MR impactor and 430 kW genset, targets concrete, asphalt and mixed demolition waste containing rebar and wood, using a 6.4 m² two‑deck screen, wind sifter and electromagnet to improve separation, fuel use and CO₂ output. The LT200HPX packages a Nordberg HP200e cone, two‑deck pre‑screen and 5.6 m² product screen on a single track chassis with wide conveyors and smart folding for high‑capacity, easily transported hard‑rock and aggregate production.

Heidelberg has supplied low carbon concrete, using carbon capture–decarbonised cement and GGBS, to Realtime Civil Engineering and Kier for the Crown Estate’s 33–35 Piccadilly redevelopment in central London. The mix design replaces a significant portion of Portland clinker with ground granulated blast-furnace slag, cutting embodied CO₂ compared with conventional CEM I concrete while maintaining structural performance suitable for a high-end commercial building. For contractors and designers, the project shows practical deployment of carbon capture–enabled binders on a constrained urban site with demanding specification control.
