Recticel has commissioned a PIR insulation recycling plant in Wevelgem, Belgium, designed to process up to 4,000 tonnes per year of post‑industrial PIR board offcuts and scrap into recycled polyol feedstock. The recovered polyol, used to manufacture new PIR boards, is expected to cut CO₂ emissions by 30–50% compared with virgin polyol, while reducing primary raw material demand. Boards incorporating the recycled content will be supplied from all Recticel plants, including UK facilities, giving specifiers a lower‑carbon option without changing product families.
ALLU Group has expanded its material processing bucket line-up with a new concrete screening and crushing attachment aimed at on-site recycling of construction and demolition waste. The unit combines screening and crushing in a single bucket, allowing excavators or loaders to process reinforced concrete, asphalt and rock without separate mobile crushers or screens. For mine and quarry operators, this can reduce haulage of oversize or waste material, cut reliance on fixed crushing circuits, and support backfilling or road-base production directly at the face.
Screencore has launched the Orbiter 206R trommel, a 31‑tonne unit with a 7m³ hopper, 1,200mm heavy belt, and variable feed angle designed to maintain unencumbered material flow. The machine uses independent, radio‑controlled belt speed controls and a large PLC interface with full‑auto functionality, plus a Cat engine on 4m tracks with two‑speed drive and remote control for site mobility. A 180° radial fines conveyor with radio remote and auto‑functionality targets higher stockpile volumes and reduced loader rehandling on constrained sites.
Government plans to nationalise British Steel aim to preserve domestic production of structural sections, plate and rail steel used in major UK infrastructure, but raise questions over long‑term subsidy levels and exposure of public finances. Civil contractors reliant on BS EN 10025 and BS EN 10210 compliant sections could see short‑term supply stability, yet face potential cost volatility if state ownership drives changes in pricing, energy cost pass‑through or decarbonisation investment. The move also concentrates risk for large public works pipelines such as HS2, road bridges and offshore wind foundations.
Ionic Rare Earths has led a UK–European collaboration with Less Common Metals, GKN and Ford UK to complete what it calls the Western world’s first end-to-end recycled rare earth supply chain for EV motor magnets, using “made-in-Belfast” long-loop recycling technology. Recycled neodymium, dysprosium and terbium oxides at >99.5% purity were converted by LCM into strip alloy, then into GKN magnets that passed Ford Dunton rotor durability tests with performance equivalent to production magnets. The Belfast commercial recycling plant will feed LCM alloy production for Ford’s UK EV facilities, directly supporting the UK Critical Minerals Strategy target of sourcing 20% of mineral needs from recycling by 2035.
Fox Group has acquired surfacing contractor DSD Construction and concrete producer Moore Readymix, in a Stellex Capital Management-backed deal aimed at building a circular economy-focused construction materials business. The move expands Fox’s footprint in asphalt surfacing and ready-mixed concrete supply, integrating upstream materials with contracting services. For civil and highways projects, the combined group signals tighter control of aggregates, asphalt and concrete logistics, with potential for increased use of recycled materials in pavements and structural concrete mixes.
UK Steel has strongly welcomed the prime minister’s plan to take British Steel into public ownership, calling it a decisive move to secure a “strategically vital” part of the UK steel supply chain. Nationalisation of British Steel’s integrated works at Scunthorpe and associated rolling and finishing facilities is expected to stabilise domestic supply of structural sections, rail and plate for major infrastructure schemes. For civil and geotechnical contractors, a more secure UK steel base could reduce procurement risk on long-lead items and support tighter control of material specifications and certification.
Urenco has completed a UK trial to produce Europe’s first batch of LEU+ nuclear fuel, enriched above conventional low-enriched uranium yet still below the 20% U‑235 threshold, for use in existing gigawatt-scale reactors and planned small modular reactors. The higher assay fuel is designed to extend fuel cycle length compared with standard LEU, potentially reducing refuelling outages and spent fuel volumes per megawatt-hour. For civil and nuclear engineers, LEU+ could influence core design margins, outage scheduling, and long-term storage and transport requirements for higher-burnup fuel.
Norwegian synthetic graphite producer Vianode has signed a Letter of Intent with South Korea’s JR Energy Solution to supply anode-grade synthetic graphite for EV and stationary storage batteries, initially from the Via ONE plant in Norway and later from the planned large-scale Via TWO facility in St Thomas, Ontario. The partners will run joint product validation and qualification programmes and work on supply chain integration to deploy Vianode’s low-emission synthetic graphite technology. With more than 95% of synthetic graphite for lithium-ion cells currently sourced from China, the deal signals a push to diversify anode material supply into Europe and North America.
B&B Attachments has launched an enhanced BlockMaster range of forklift-mounted handling attachments for bricks, blocks, flags and kerbs, aimed at high-throughput, abrasive yard conditions where product damage must be tightly controlled.

Bespoke designs allow sites to match clamp geometry and rotation to specific pack sizes and curing states, improving handling precision and reducing breakage.
Epiroc has launched the EC 122 hydraulic breaker, 80kg lighter than its predecessor with a 1,120kg service weight for 15–24t carriers, combining a nitrogen piston accumulator with an integrated control valve and energy recovery system to stabilise impact energy and improve hydraulic efficiency. A new turnable lower wear insert and replaceable piston liner allow field rotation and replacement without special tools, cutting downtime and repair costs. VibroSilenced Plus housing with isolated percussion mechanism and sealed openings reduces noise, vibration and internal wear for longer service intervals.
Labour’s plan to deliver higher annual housebuilding volumes is at risk as brick manufacturers warn that high gas and electricity costs could curtail kiln operations and capacity. A construction trade union is calling for targeted energy support for UK brickworks, where continuous-firing kilns and dryers are exposed to volatile wholesale prices and carbon costs. Any reduction in domestic brick output could lengthen programme durations, increase reliance on imports with longer lead times, and complicate cost planning for masonry-heavy schemes.
Doka has earned an EcoVadis Silver rating in the 2026 assessment, placing the formwork and scaffolding specialist in the top 15% of more than 150,000 rated companies and scoring 91/100 in the environmental category. The company is targeting net zero by 2040 through expanded on-site photovoltaics, fleet electrification and value-chain emission cuts, backed by Science Based Targets initiative commitments. For contractors, Doka’s rental-based circular model, refurbishment services, Xlife top formwork sheet with recycled content, and product carbon footprint data for over 7,000 items offer practical levers to reduce project embodied carbon.
Australia’s asphalt sector, led by guidance from the Australian Flexible Pavements Association (AfPA) and Projects Technical Advisor Trevor Distin, is pushing performance-based mix design to exploit asphalt’s 100 per cent recyclability and cut pavement carbon. Reclaimed asphalt pavement (RAP) is being reprocessed into new surface and base courses, with higher RAP contents enabled by rejuvenators, tighter binder grading and improved plant controls. For designers and asset owners, the shift means specifying functional performance (rutting, fatigue, texture, skid resistance) and lifecycle cost rather than prescriptive mix recipes.
The US Department of Energy’s TRACE-Ga initiative is awarding about $5.4 million to five firms to design and validate flowsheets to restart primary gallium production, after nearly 40 years of zero domestic output and 100% import reliance under China’s 98% global supply dominance. PHNX Materials will target non-traditional waste streams to co-produce gallium, supplementary cementitious materials, alumina and ammonium sulphate, while Atlantic Alumina and Found Energy will apply counter-current ion exchange, electrochemistry and Direct Bayer Extraction to recover gallium from hot, dilute Bayer liquors. Kunin Technologies aims for a 12 tpa gallium pathway from high-Ga metal streams, and Indium Corporation will build recycling-based recovery from scrap, signalling new process options for alumina refineries and metallurgical residues.
Murphy has completed the UK’s first permanent works pour using Ecocem ACT low‑carbon concrete, marking a shift from traditional CEM I mixes on a live infrastructure scheme. Ecocem ACT is a clinker‑reduced binder system designed to cut embodied CO₂ significantly while maintaining CEM I‑equivalent strength and setting performance, enabling direct substitution in structural elements. For designers and contractors, this early UK deployment provides a live reference for specification, QA testing, and durability assessment of next‑generation low‑carbon binders in permanent works.

Former Lafarge chief executive Bruno Lafont has been sentenced by a French court to six years in prison and the company fined more than €1m for developing what the presiding judge called a “genuine commercial partnership with IS” around its £680m Jalabiya cement plant in northern Syria. Lafarge Cement Syria was found to have paid about €5.6m to Islamic State, Jabhat al-Nusra and intermediaries to keep the plant and its supply trucks operating after 2013, when militants controlled the area. The ruling links corporate payments to militant control of local natural resources, raising acute compliance and security-risk questions for construction materials firms operating in conflict zones.
US silicon and germanium producer Lattice Materials has broken ground on an 80,000-square-foot manufacturing facility in Bozeman, Montana, backed by an $18.5 million US Department of War investment to expand domestic photonics-grade optical materials capacity. Scheduled to start construction in May 2026 and complete in 2027, the plant will more than double Lattice’s footprint and add large optical boule growth, expanded internal processing, and higher-precision machining and metrology. New recycling lines will convert scrap into seed crystals, cutting reliance on imported silicon and germanium feedstock.
Steico has appointed Andy Cook and Pete Kelly as specification managers to expand use of its wood fibre insulation systems ahead of the UK Future Homes and Building Standards.

Neo Performance Materials has produced its first separated terbium and dysprosium oxides from mixed rare earth carbonate at the newly commissioned solvent extraction line at its Silmet plant in Estonia, now running at nameplate capacity. The heavy rare earth output is designed to feed Neo’s sintered magnet plant in Narva, which opened in September as Europe’s first mass-production facility with an initial capacity of 2,000 tonnes per year. Neo is now concentrating on stabilising product purity before ramping to routine production, while maintaining full traceability across its European light and heavy rare earth value chain.
Approval of a 60 per cent Supplementary Cementitious Material (SCM) concrete mix by VicRoads for road and transport projects across Victoria marks a major shift in allowable low-carbon binders for state infrastructure. The mix, developed and trialled with Geoquest Australia, replaces the majority of Portland cement with SCMs such as fly ash and slag, cutting embodied carbon while maintaining performance to VicRoads specifications. Designers and contractors can now specify substantially higher SCM contents on VicRoads projects without seeking project-by-project exemptions.
Latrobe Magnesium has secured a non-dilutive prepayment from its US distribution partner Metal Exchange LLC to advance its Latrobe Valley magnesium production project, which uses fly ash from brown coal power generation as feedstock. The funding supports commissioning of LMG’s initial commercial plant designed to produce magnesium ingots and supplementary products such as cementitious material from waste residues. For mining and materials engineers, the deal signals growing commercial backing for ash-to-magnesium processing as an alternative to conventional dolomite- or magnesite-based routes.
NASA’s Orion spacecraft programme is driving demand for advanced alloys, with aluminium‑lithium in the crew module to cut mass, titanium for primary structural members, and nickel‑based superalloys in engines to withstand extreme thermal loads. These specifications exemplify how deep-space missions are tightening requirements on fatigue life, high‑temperature creep resistance and weldability in lightweight alloys. For miners and metallurgical suppliers, the mix of Al‑Li, titanium and high‑nickel feedstocks signals sustained demand for high‑purity ores and tightly controlled processing routes.
State Asphalts NSW is pivoting from being primarily a surfacing contractor to developing next‑generation bitumen binders, leveraging 56 years of mix design and pavement performance data across New South Wales networks. A fully commissioned production plant and recent successful binder trials position the company to supply customised polymer‑modified and high‑RAP compatible binders tailored to local traffic loading and climate conditions. For road authorities and civil contractors, this signals a growing local source of performance‑specified binders that can support longer‑life pavements and higher recycled content without major changes to existing asphalt plants.
Geothermal Engineering Ltd has begun commercial-scale production of zero‑carbon lithium carbonate at its United Downs geothermal power plant in Cornwall, using Watson‑Marlow 630 and Qdos peristaltic pumps for reagent dosing. The pumps provide sealed, low‑maintenance chemical transfer with precise flow control, supporting closed‑loop extraction from hot brines and reducing operator exposure to corrosive fluids. For process engineers, the choice of peristaltic technology signals a preference for accurate metering and simplified containment over more complex diaphragm or centrifugal dosing systems in geothermal lithium circuits.

The Mineral Products Association has appointed former Cemex communications and public affairs director Martin Casey as senior director for cement and lime, succeeding Diana Casey after more than 20 years with the producer and a year consulting for the MPA on government engagement. His appointment comes as UK cement imports have tripled in two decades while domestic output has fallen to a 75‑year low, intensifying pressure on local kilns and clinker capacity. New EU carbon border charges this year are expected to divert more global cement shipments towards the UK, sharpening competitiveness and carbon‑policy risks for domestic producers.
Wienerberger’s Denton brickworks will become the world’s first commercial‑scale hydrogen‑fired brick plant after securing UK Industrial Energy Transformation Fund backing for a £6m retrofit of two tunnel kilns from natural gas to 100% green hydrogen. The project will replace 224 gas burners, add dedicated hydrogen offloading and pressure‑reduction infrastructure supplied for 15 years by Trafford Green Hydrogen via tube trailers, and upgrade electrical and control systems without altering kiln structures. One fully converted kiln, or two partially converted, is targeted by autumn 2027, with full hydrogen firing from 2028 cutting CO₂ by over 11,600 tonnes per year (around 9% of Wienerberger Limited’s Scope 1 and 2 emissions).
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.
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.
Atlas Copco has launched QHS integrated hybrid generators that combine battery storage and a diesel genset in a single canopy unit, capable of grid charging, self-charging via the engine, and optional solar panel input. The system automatically manages multiple energy sources to minimise engine runtime, claiming up to 80% fuel and CO₂ reductions and more than 95% less engine operating time versus diesel-only sets at low or variable loads. Rental-focused features include multiple socket configurations, external fuel connections, a terminal board and FleetLink telemetry for remote monitoring, diagnostics and fleet management.
The World Gold Council has launched “Gold as a Service”, an open, shared infrastructure concept co-developed with Boston Consulting Group to link vaulted physical custody directly with digital issuance and management of gold-backed products. The proposed platform standardises custody coordination, reconciliation, compliance and redemption to support scalable, interoperable tokens and other digital gold instruments that can plug into modern trading, clearing and recordkeeping systems. WGC is inviting banks, fintechs, custodians and other market participants to help design the “trusted rails” needed to operate digital gold at market scale without compromising bar-level integrity.
Australian researchers led by CSIRO have built the world’s first proof‑of‑concept quantum battery, using entangled quantum states to charge multiple cells collectively rather than individually. The lab‑scale device, fabricated in CSIRO’s clean quantum battery engineering lab, is designed to scale to solid‑state architectures compatible with grid‑scale storage and electric vehicles. If commercialised, the technology could sharply increase demand for high‑purity critical minerals such as lithium, nickel, cobalt and rare earth elements, with tighter specifications on impurity control and crystal defect behaviour.
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.
Government spending of £377M over nine months has been required to keep British Steel’s two Scunthorpe blast furnaces operating following emergency intervention by the Department for Business and Trade in April 2025, the National Audit Office has reported. The support covers ongoing operation of the integrated works, including coke ovens and basic oxygen steelmaking, which supply long products and rail sections critical to UK infrastructure projects. Engineers face continued uncertainty over future capacity, investment in low‑carbon steelmaking routes, and long‑term security of domestic steel supply for major schemes.
Rio Tinto has completed an industrial trial with Prysmian to produce low‑carbon aluminium rod for power cables, blending metal from its hydro-powered Alma smelter in Quebec with ELYSIS inert-anode technology that eliminates direct smelting greenhouse gas emissions and generates oxygen. The trial sits within a five-year supply agreement signed in October 2023 to roll out lower‑carbon aluminium cable solutions for energy transmission and data centres. CRU forecasts data centres will grow from about 7% of North American cable demand in 2025 at roughly 17% CAGR to 2030, with aluminium gaining share for campus power distribution.
Hydrogen has been used by Heidelberg Materials UK to decarbonise asphalt production on an industrial scale for the first time in the UK, replacing conventional fossil fuel combustion in the drying and heating phase of the mixing process. The trial, conducted in a full-scale asphalt plant rather than a laboratory rig, demonstrates that hydrogen burners can maintain production temperatures and binder performance within standard specification limits. For pavement designers and contractors, this signals emerging scope to cut Scope 1 emissions from asphalt plants without changing mix designs or laying procedures.
Brick and block producer Forterra delivered 2025 revenue of £386.0m, up 12.1% year-on-year, with adjusted profit before tax rising 62.9% to £36.0m despite muted aircrete and aggregate block despatches and an 8% fall in UK domestic brick despatches in January 2026 versus January 2025. Output gains came from both kilns at the Desford brick factory running simultaneously for the first time and near-complete redevelopment of the Wilnecote plant, plus strong demand for Bison precast concrete flooring. Statutory results absorbed £6.7m of restructuring costs from closing the Formpave and Bison Bespoke Precast divisions, while Forterra launched its Omnia extruded brick slip range at Accrington.
Heidelberg Materials has produced 1,303 tonnes of asphalt at its Criggion quarry in Powys using 100 per cent hydrogen in place of liquid fossil fuels, in what is claimed as the UK’s first hydrogen-fuelled asphalt production run. The trial, part-funded under DESNZ’s Industrial Hydrogen Accelerator, consumed 4,522 kg of hydrogen and cut scope 1 emissions by 76 per cent, equating to a 23 per cent reduction in product carbon footprint and 25,105 kg of CO₂ saved. If replicated across UK asphalt plants, the approach could abate around 450,000 tonnes of CO₂ annually, pending proof of commercial viability.
Leading manufacturers of insulating glass units are adopting laser distance sensors to monitor and precisely adjust glass panel positioning during automated assembly. Dimetix D‑Series laser distance sensors, supplied locally by AMS Instrumentation & Calibration, provide non-contact measurement over several metres with millimetre-level accuracy, enabling closed-loop control of panel spacing and alignment. For mining and industrial plant glazing, this level of positional control reduces rework, improves seal integrity in multi-pane safety glass, and supports consistent thermal and acoustic performance in harsh environments.
Plastic pipe manufacturer Polypipe Building Services has invested £1.5m in automation, £3m in moulding machinery and £2.5m in extrusion technology at its 24-hour, five-day Aylesford plant, moving key lines to fully automated operation. Six-axis and Cartesian robots now handle production and packaging, while an IV4 AI vision camera counts parts and flags dimensional variation, ovality and moulding defects before dispatch. Operator loading has shifted from one operator per machine to typically one per four machines, with staff redeployed and further automation planned in the fabrication department.
Breedon has completed its acquisition of Booth Precast Products in Abbeyleix, County Laois, adding a long-established sand and gravel quarry and processing plant that has supplied the Irish construction market for over 25 years. The deal, agreed in December 2025 and cleared by the Republic of Ireland’s Competition Authority, secures additional mineral reserves to serve the growing Dublin market. Integration of Booth’s concrete operations gives Breedon Ireland a more vertically integrated aggregates-to-concrete supply chain for regional infrastructure and building projects.
The UK Concrete Show 2026 at Birmingham’s NEC on 25–26 March will run a seminar programme centred on decarbonisation, materials innovation, digital monitoring, performance verification, and skills development for concrete producers and specifiers. Sessions will address low‑carbon binders and mix designs, sensor‑based monitoring of pours and in‑service structures, and verification of performance against evolving standards. The focus on skills suggests practical content for contractors, precast manufacturers, and designers needing to integrate new materials and digital QA/QC into existing workflows.
SAMI Bitumen Technologies has opened a new technical centre to expand research and development of bitumen additives and performance enhancers for Australian road construction and maintenance. The facility centralises laboratory testing, product formulation and quality control for polymer-modified binders, emulsions and warm-mix technologies, improving collaboration between SAMI’s technical teams and its large-scale production network. For pavement designers and asset owners, the centre signals faster validation of high-performance binders and more consistent field performance data for heavily trafficked highways and sprayed-seal networks.
Precast manufacturer Tobermore Concrete Products has been fined £160,000 at Londonderry Crown Court after production team leader Colin Thomas was fatally crushed on 26 April 2023 at the HESS1 block manufacturing line at its Lisnamuck Road plant. Thomas entered a fenced pit area for cleaning when a horizontal latch conveyor restarted, trapping him between the moving conveyor and fixed structure because the line had not been fully isolated and locked out. HSENI found unclear interlock zoning, absence of safety light sensors on HESS1 despite their use on similar lines, and inadequate supervision of cleaning and maintenance practices.
Swiss researchers have strengthened ageing bridge decks by embedding heat‑activated iron‑based shape memory alloy (Fe‑SMA) bars within an ultra‑high‑performance fibre‑reinforced concrete (UHPFRC) overlay, creating active prestress when the bars are heated. The Fe‑SMA bars contract on activation and lock in compressive stresses as the UHPFRC hardens, improving fatigue performance and crack control without adding significant self‑weight. This approach offers a thin, bonded strengthening layer that can be installed on existing decks with minimal clearance loss and limited traffic disruption.
Circular, UK-made steel is being promoted as a route to cut embodied carbon in buildings and infrastructure while reducing exposure to volatile global supply chains. By using scrap-based electric arc furnace production and designing for disassembly and reuse of beams, columns and plate, contractors can lower lifecycle emissions compared with imported basic oxygen furnace steel. For geotechnical and civil teams, specifying circular steel in piles, retaining structures and frames will increasingly be driven by client net-zero targets and whole-life carbon assessments.
