IperionX has secured a US Army SBIR Phase III contract allowing US defence agencies to place titanium orders up to a collective $99 million, with the first two task orders worth about $19.8 million. Funding will expand integrated titanium powder-to-finished-component production at its Virginia facility, adding continuous HSPT and dehydride furnace capacity and bringing titanium fastener finishing fully in-house. The programme targets industrial-scale manufacture of titanium track pins, bolts and fasteners, with inspection and acceptance planned at Detroit Arsenal and Aberdeen Proving Ground, and may extend to aerospace‑grade components.

Doka has published product carbon footprints for more than 9,000 formwork and related products, giving contractors project-specific CO₂ data for lifecycle assessments and procurement decisions. The company, led on sustainability by Julia Weber, is targeting net zero by 2040 and has committed to cut Scope 1, 2 and 3 emissions by 42% by 2030, in line with the Science Based Targets initiative and the Paris Agreement 1.5°C pathway. For designers and temporary works engineers, the expanded dataset enables more accurate embodied carbon calculations at product and system level.

Modern highway construction is shifting towards low-carbon materials such as geopolymer concrete, high-recycled-content asphalt and bio-based binders to cut embodied CO₂ and improve performance under higher traffic loads and more intense rainfall. Designers are trialling warm-mix asphalt to reduce laying temperatures by 20–40°C and using secondary aggregates from construction and demolition waste to limit quarrying and landfill. Key challenges include variable material quality, limited long-term durability data, gaps in standards and specifications, and the need to adapt pavement design methods and site quality control.
