    Wales infrastructure ‘structural issues’: planning and delivery lessons for engineers

    Wales faces mounting capacity and resilience pressures across energy, water, transport, digital and circular-economy infrastructure, with an independent assessment for the National Infrastructure Commission for Wales calling for a fundamental overhaul of planning, funding and skills systems. The review points to fragmented decision-making between Welsh Government, local authorities and regulators, and warns that current investment pipelines and consenting processes are too slow to deliver long-life assets such as grid upgrades, strategic rail and road corridors, and wastewater treatment improvements. For engineers, the message is to expect tighter scrutiny on whole-life carbon, resilience and regional coordination in future Welsh schemes.

    Tony Gee CEO on UK infrastructure: delivery and risk lessons for civil engineers

    Tony Gee and Partners chief executive Alasdair Fowler argues that civil engineers must tackle systemic issues in UK infrastructure delivery, including fragmented risk allocation between clients, designers and contractors and short-term procurement focused on lowest capital cost. He calls for earlier contractor involvement, integrated design–build teams and longer-term alliancing frameworks to reduce rework, claims and programme overruns on major schemes such as highways and rail upgrades. Fowler also stresses that better data on whole-life performance and carbon, aligned with NEC contracts, should drive design decisions rather than purely initial cost.

    Leading the charge: second-life EV batteries on site – safety and design notes

    Rapid adoption of electric vehicles is creating a growing stream of “nearly new” traction batteries, and a specialist firm is repurposing these packs into temporary power units for construction sites. The systems aggregate multiple second-life EV modules into containerised battery energy storage, capable of running site cabins, tower cranes and small plant that would traditionally rely on 100–300kVA diesel generators. For contractors, this points to lower fuel logistics, reduced local emissions and quieter operation, but also raises questions on battery health monitoring, fire safety strategy and end-of-second-life recycling routes.

    Carbon-catching concrete: Paebbl’s CO₂ mineralisation explained for engineers

    Nordic–Dutch startup Paebbl is producing an olivine-based cement substitute via accelerated CO2 mineralisation in low-energy reactors, claiming a net negative footprint of –14.4kg CO2‑equivalent per tonne (cradle-to-gate) and storage of about 21kg CO2 per m³ of concrete at typical replacement rates. The material has moved from gramme-scale tests to an operational pilot in 18 months and has already been used in a Rotterdam quay wall grout by Hakkers, the 1917 Veerhuis restoration, and a 7m-span “carbon-neutral” concrete footbridge by Heijmans. Classified as CCUS, the process permanently binds captured industrial CO2 into stable carbonate minerals that remain locked in even after demolition, offering structural-grade, carbon-storing concrete mixes rather than purely low-embodied-carbon variants.

    PFAS ‘forever chemicals’: design and risk implications for civil engineers

    Per- and polyfluoroalkyl substances (PFAS) are shifting from a niche contamination issue to a core design constraint for water, wastewater and brownfield infrastructure, as regulators tighten limits on “forever chemicals” in soil and groundwater. Civil engineers are being pushed to integrate PFAS-specific measures such as high-pressure membrane treatment, granular activated carbon and specialised landfill liners into drainage, flood defence and remediation schemes. The trend signals more complex risk assessments, higher lifecycle costs and potential redesign of legacy assets where PFAS-impacted leachate or run-off was not previously considered.

    Lidl balcony solar panels in GB: regulatory and grid impacts explained

    Plug-in balcony solar panels will go on sale in Lidl stores across Great Britain within months, following government moves to modernise regulations for “plug-and-play” devices that connect via a standard mains socket without formal installation. The UK is drawing on continental experience, where Germany alone adds around 500,000 such micro-PV units a year, to cut household grid demand and exposure to volatile fossil fuel prices linked to the Iran war and wider Middle East conflict. In parallel, the new Future Homes Standard will require most new low-rise homes to incorporate on-site renewable electricity generation, predominantly roof-mounted PV, alongside low-carbon heating such as heat pumps or heat networks.

    Government late payment powers: contract and retention impacts for engineers

    Government plans to ban retention withholding in construction, cap payment terms from large firms to small suppliers at 60 days, and mandate late-payment interest at 8% above the Bank of England base rate written into contracts. The Small Business Commissioner would gain powers to investigate suspected poor payers, adjudicate disputes outside court, and levy “significant” fines in the tens of millions, plus force large companies to publish explanations for poor performance. Construction bodies, including the National Federation of Builders, are pushing for alternative performance mechanisms such as accessible surety bonds or insurance during the consultation on the retention ban’s implementation.

    Sasquatch Resources’ Mount Sicker waste rock: design and risk notes for mine engineers

    Sasquatch Resources is targeting roughly 300,000 tonnes of sulphide-bearing waste rock at the historic Mount Sicker copper-gold district on Vancouver Island, where legacy piles with a neutralisation potential of 0.2 and open shafts up to 200 feet deep continue to generate acid runoff and physical hazards. Modern sampling of the surface waste has returned average grades of about 2 g/t gold plus copper, silver and zinc, and the company plans to crush and process the material using density and X-ray fluorescence (XRF) ore-sorting in a closed-loop, reagent-free circuit. Because the project involves large-scale reprocessing without new mining, Sasquatch is working with regulators to craft a bespoke permitting pathway that could be replicated across an estimated 2,000 legacy mine sites in British Columbia.

    Turning sawdust into fire‑resistant boards: design notes for materials engineers

    Researchers at ETH Zurich and Empa have developed a recyclable sawdust–struvite composite board that is stronger in compression perpendicular to grain than spruce and shows cone calorimeter ignition times of 45 seconds, around three times longer than untreated timber. The material uses an enzyme from watermelon seeds to control crystallisation of struvite from newberyite, forming large crystals that infill voids between sawdust particles and act as an inorganic flame retardant, potentially matching cement‑bonded particleboard fire classes with only 40% binder by weight. Panels can be mechanically ground, heated to just over 100°C to release ammonia, and fully separated for reuse or as a phosphorus fertiliser, with future cost reductions possible by sourcing struvite from sewage treatment plant deposits.

The process is designed to treat complex copper concentrates and potentially higher-arsenic feeds that challenge traditional smelters, using closed-loop reagent recovery to cut reagent consumption and waste volumes. For mine operators and project designers, this signals growing scope to permit smaller-footprint plants and reconsider concentrate transport versus on-site refining economics.

    Federal and QLD govts fund Mount Isa–Duchess upgrades: design notes for engineers

    Approximately 25 kilometres of the Mount Isa–Duchess Road in Queensland’s Cloncurry Shire will be sealed under joint Federal and State government funding to improve long-term flood resilience. The upgrade targets all-weather access for heavy mining and pastoral haulage, reducing closures on a key inland freight route that currently suffers from wet-season isolation. For geotechnical and pavement designers, the focus will be on flood-resistant formation, drainage capacity and surfacing able to withstand high axle loads from road trains.

    ABx rare earths grants: leach testwork and project economics for mine planners

    ABx Group has secured roles in two Federal Government-backed research initiatives to advance rare earths extraction from its ionic adsorption clay deposits in northern Tasmania and bauxite-hosted resources in Queensland. The grants, awarded under national critical minerals and industry growth programmes, will fund testwork on low-acid leach processes, beneficiation flowsheets and pilot-scale recovery of magnet rare earths such as neodymium and praseodymium. Outcomes could materially affect project economics, tailings chemistry and permitting pathways for clay-hosted rare earths developments in Australia.

    NSW coal strategy and mine extensions: design and approvals lens for planners

    New South Wales has released a long-term coal strategy that centres on extending existing coal mines rather than approving large new greenfield projects, aiming to sustain regional employment and export royalties. The plan signals continued support for thermal and metallurgical coal operations in the Hunter Valley and Illawarra, giving operators more certainty for multi‑year life‑of‑mine extension studies, reserve reclassification and staged approvals. Geotechnical and mine planners can expect stronger regulatory focus on incremental pit and panel expansions, tailings storage capacity and progressive rehabilitation commitments tied to extension consents.

    Jameson Cell at Mogalakwena North: low mass pull flotation insights for PGM engineers

    Glencore Technology’s Jameson Cell is now operating at Anglo American Platinum’s Mogalakwena North Concentrator, enabling Valterra Platinum to fully implement a low mass pull strategy in the PGM flotation circuit. By targeting a smaller, higher-grade concentrate stream, the Jameson Cell’s high-intensity aeration and fine bubble generation are being used to lift recovery while cutting circulating loads, reagent consumption and overall energy use. The move signals wider interest in compact, low-footprint flotation technology for brownfield PGM concentrators constrained by existing plant layouts and tailings capacity.

    Boliden Garpenberg hoist investment: design and energy notes for mine engineers

    Boliden is investing SEK 4 billion in a new hoist system at its Garpenberg Zn-Pb-Cu-Ag-Au mine to enable a shift from diesel truck ramp haulage to electric hoisting, cutting ramp traffic and power demand peaks while supporting deeper mining. A further SEK 1.5 billion will fund an industrial demonstration plant at the Rönnskär smelter to produce supplementary cementitious material from process residues, targeting partial clinker replacement in concrete. Together, the projects aim to improve unit earnings and reduce lifecycle emissions in both mining and downstream materials use.

    Electric paver debuts on A47: productivity and CO₂ lessons for road engineers

    An Ammann eABG 4820 electric paver has been deployed on National Highways’ A47 upgrade between Acle and Great Yarmouth, laying asphalt with over 90% recycled content alongside an electric Ammann eARX 26-2 tandem roller. The paver, claimed as the largest electric unit on the market, delivers up to 1,200 tonnes per day at 500 t/h with a 70% CO₂ reduction versus diesel, typically finishing night shifts at around 40% battery from a 95% start while placing 500–600 tonnes. Heidelberg Materials supported the trial by installing a nearby recycling plant that both supplied reclaimed material and provided daytime charging, with low-carbon hydrogen low loaders handling transport.
