    Legrand green steel cable management: embodied carbon cuts explained for project teams

    Legrand green steel cable management: embodied carbon cuts explained for project teams

    First reported on The Construction Index

    30 Second Briefing

    Legrand is now supplying cable management systems made with 34% green steel, targeting high‑demand data centre projects that can require hundreds or thousands of kilometres of cabling. The green steel uses at least 75% scrap in electric arc furnaces powered by certified renewable electricity, cutting embodied carbon from about 2.38t CO2e to as little as 799kg CO2e per tonne of finished cold‑rolled steel, a 70% reduction versus blast furnaces. This shift is already lowering Legrand’s Scope 3 supply‑chain emissions and offers contractors a straightforward route to reduce project embodied carbon.

    Technical Brief

    • Emissions for finished cold‑rolled green steel are reported as low as 799 kg CO2e per tonne.
    • Conventional blast furnace route cited at 2.38 t CO2e per tonne of comparable cold‑rolled steel.
    • Scope 3 reductions from green steel build on prior Scope 1 and 2 cuts at UK operations.
    • Additional decarbonisation measures include solar PV at Consett and Cramlington plus wider renewable electricity procurement.

    Our Take

    Using green steel with at least 75% scrap content at Consett and Cramlington positions Legrand ahead of many UK building-products suppliers in our coverage, where most low-embodied-carbon offerings still rely on incremental efficiency gains rather than wholesale feedstock changes.

    The drop from 2.38 t CO2e to as little as 799 kg CO2e per tonne of cold-rolled steel suggests that specifying Legrand UK & Ireland cable management could make a measurable difference to whole-of-building embodied carbon calculations on BREEAM- or LEED-driven projects.

    Being rated in the top 1% by EcoVadis gives Legrand a third‑party credential that procurement teams in UK and Irish infrastructure projects increasingly use as a pre-qualification filter, which may favour its systems over lower-cost but less transparently rated competitors.

    Heidelberg’s Manchester recycling expansion: process and design notes for engineers

    Heidelberg Materials has expanded its Agecroft recycling site in Swinton, Manchester with the UK’s largest wash plant, capable of processing up to 450,000 tonnes of excavated waste a year and fitted with a near-closed-loop drainage and water recovery system. The plant separates, washes and upgrades mainly soil-based construction, demolition and industrial arisings into high-quality recycled aggregates under strict contamination-control protocols. A new rail siding now brings primary aggregate from Horton quarry in the Yorkshire Dales, cutting HGV movements and CO₂ for supply into the Manchester market.

    Tenaris TN 95EY steel for Canadian operators: materials and sour service notes

    Tenaris has begun domestic production of its proprietary TN 95EY steel grade at its Sault Ste. Marie Industrial Centre, the only North American facility manufacturing both seamless and welded pipe under one roof, targeting high-pressure, high-temperature sour service wells in the Montney and Duvernay formations. The company has invested over C$355 million in Canada since 2020, including a C$306 million modernisation and expansion programme announced in May 2026 with federal and Ontario government support. Local TN 95EY output required retooling existing processes plus comprehensive per-pipe testing and traceability, tightening supply chains for Canadian oil and gas operators.

    Lawrence Tech critical materials challenge: process and recycling lens for engineers

    Centrepolis Accelerator at Lawrence Technological University has launched the Critical Materials Manufacturing Technology Accelerator with USCAR, offering a $100,000 grand prize and pilot-scale commercialisation support for technologies that cut US dependence on imported critical materials and rare earth elements. The Innovation Challenge targets processes and materials that can move rapidly from lab to production for automotive, aerospace, energy, electronics and defence components, including batteries, motors, power electronics and structural parts. Eligible proposals must focus on processing, substitution or end‑of‑life recovery and recycling, not mineral exploration, mining or primary ore extraction.
