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.

Clean tech startup Voya Energy has secured US$35 million, led by Energy Impact Partners with backing from John Doerr and others, to commercialise aluminium-based metal fuel generators for large off-grid users such as data centres and industrial plants. The system uses low‑grade scrap aluminium pellets in a proprietary metal‑air cell with custom electrolyte, producing electricity electrochemically with no on-site combustion or air emissions and operating independently of the grid. Current designs target up to 2 MW per 20‑foot containerised generator with a separate 10‑foot fuel module holding about 100 MWh, scaling to roughly 100 MW and 10 GWh per acre.

The Interface 5600 2-Axis Axial Torsion Load Cell combines compressive force and torsional moment measurement in a single flange-mount transducer, capturing both at the same point for demanding test and measurement rigs. Its compact, multi-axis design reduces fixture complexity compared with separate axial and torque sensors, freeing space around test specimens and simplifying alignment. For mining equipment OEMs and materials labs, the unit supports more accurate characterisation of drill strings, couplings and rotating components under combined loading.
