Australian-owned Vital Chemical, approaching its 50th year, is supplying erosion and dust control solutions to major Queensland civil and construction projects, with products formulated for environmentally and sustainably sound performance. The company’s portfolio targets typical road and earthworks issues such as exposed batter erosion, haul road dust and stockpile stabilisation, aiming to reduce sediment run-off and particulate emissions without relying on traditional solvent-based binders. For geotechnical and civil contractors, this signals wider availability of project-scale, compliance-focused surface treatments that can be integrated into construction environmental management plans.

Carbon Capture, Usage and Storage (CCUS) is being positioned as a core element of UK decarbonisation strategy for gas-fired power and hard-to-abate materials such as cement and concrete, with Mitsubishi Heavy Industries promoting large-scale post-combustion capture units integrated with existing plants. Critics question lifecycle emissions, high energy penalties for solvent-based capture, and long-term integrity of offshore geological storage. For civil and materials engineers, the debate centres on retrofit feasibility at existing cement kilns, pipeline and compression infrastructure requirements, and whether CCUS investment may delay process changes or clinker substitution.

Panama will publish on Friday a third‑party environmental audit of First Quantum Minerals’ shuttered Cobre Panamá mine, a 350,000‑tonne‑per‑year copper operation that previously generated about 5% of national GDP, to guide President José Raúl Mulino’s decision on its future after the 2023 Supreme Court ruling voided the concession. Environment minister Juan Carlos Navarro and commerce minister Julio Moltó say the extensive report, following six preliminary technical reviews, will be released “with full transparency” and is the only basis for assessing environmental compliance. The move comes as new protests in Panama City, led by Sal de las Redes and Movimiento Independiente Voluntad, oppose any restart amid claims of irreversible environmental damage and debate over an estimated $3.5 billion economic loss since shutdown.

ArcelorMittal Exploitation Minière Canada has been fined C$100 million, the largest penalty ever under Canada’s Fisheries Act, after pleading guilty to 100 counts for discharging low‑pH effluents and waters with elevated zinc, nickel and suspended solids from its Mont‑Wright and Fire Lake iron ore operations between 2014 and 2022. Nearly C$250,000 in investigation costs must also be repaid, and a detailed effluent and mine drainage management plan for both complexes is due to federal enforcement officers by mid‑February 2027. The company says it has since invested over C$400 million in permanent water control and treatment infrastructure.

Arca Technologies has secured up to C$2 million from NRC IRAP’s Clean Tech initiative towards a C$7.4 million project to move its mineral activation and engineered carbonation processes from lab to field scale, targeting alkaline wastes such as mine tailings and steel slag. The company will design containerised, field‑deployable mineralisation units and prepare a first‑of‑kind industrial pilot, billed as the first field‑scale system to accelerate carbon mineralisation in mine waste. Commercial traction includes a 10‑year offtake with Microsoft for nearly 300,000 tonnes of CO₂ removal and an early pre‑purchase from Frontier.

Jacobs has been appointed by Great British Energy – Nuclear to deliver environmental consultancy and baselining at the Oldbury site in Gloucestershire, earmarked as a potential location for a new nuclear power station. The work will characterise existing ground, groundwater, ecological and radiological conditions to support future nuclear site licensing, environmental permits and design optioneering. Early baselining data will be critical for later geotechnical investigations, foundation design, flood and coastal risk assessments, and long-term monitoring strategies if the project proceeds.

A UK Government research paper concludes that Nature-based Solutions such as floodplain reconnection, riparian woodland and leaky barriers are most effective when planned and modelled across whole catchments rather than as isolated site schemes. The study stresses integrating NbS with existing hard defences, using hydrological and hydraulic modelling to quantify peak flow attenuation and downstream level reductions under design storm events. For civil and drainage engineers, this points to earlier basin-scale option appraisal, multi-landowner agreements and long-term monitoring of storage volumes, infiltration rates and sediment behaviour.

A former Ibstock extraction site, Dalton Quarry, is being converted by Green Earth Developments Group into a biodiversity “bank” of engineered habitats to generate tradable biodiversity net gain (BNG) units for UK infrastructure schemes. The project will create a mosaic of habitat types on previously worked quarry land, allowing developers to purchase pre-accredited BNG units rather than delivering all ecological uplift within constrained project footprints. For civil and geotechnical teams, this model could influence land-take, earthworks design and long-term aftercare obligations on major road, rail and housing projects.

National Highways has appointed WSP to lead a multi-disciplinary team to deliver its Water Quality Plan targeting pollution from road run-off across the strategic road network. The commission will focus on identifying high-risk outfalls, retrofitting drainage and treatment assets such as interceptors, swales and attenuation ponds, and improving monitoring of contaminants including hydrocarbons and suspended solids. For civil and geotechnical designers, the move signals more retrofit water treatment structures at existing junctions, cuttings and embankments, with tighter controls on discharge consents.

National Highways has appointed WSP as technical partner, supported by Mott MacDonald, Ramboll, Arup and Aecom, to deliver its Water Quality Plan targeting the most polluting road run‑off discharges on the Strategic Road Network by 2030. The programme will design and implement treatment for high‑risk outfalls using nature‑based systems (e.g. swales, wetlands) and mechanical solutions installed within existing highway boundaries, focusing on oils, tyre‑derived suspended solids and brake‑related metals. For designers and geotechnical teams, this signals significant upcoming work on retrofit drainage, attenuation and treatment assets constrained by current carriageway footprints.

Mining operators are increasingly using spill bunded pallets to contain fuels, lubricants and other hazardous liquids stored in workshops, laydown yards and processing areas, reducing the risk of unplanned releases to soil and drainage systems. Eco Pallets’ moulded polyethylene bunded units, shown in use at Tanafloc Australia, integrate forklift pockets, removable grates and corrosion‑resistant sumps sized to capture typical drum and IBC failure volumes. For geotechnical and environmental teams, this simplifies compliance with bunding requirements, reduces contaminated run‑off, and limits the footprint of lined or remediated ground.

Carbon Direct has partnered with Arca to co-develop and market Arca’s Industrial Mineralization (IMin) carbon dioxide removal credits, based on accelerated mineralisation of alkaline mine and steelmaking waste. The technology, validated in an 18‑month pilot with BHP at an active Australian mine, has already secured a 10‑year offtake from Microsoft for nearly 300,000 tonnes of CO₂ and an early prepurchase from Frontier. With 16.5 billion tonnes of suitable legacy waste and 3 billion tonnes produced annually, Arca targets durable (>10,000‑year) CO₂ storage with potential tailings stabilisation co‑benefits.

Construction clients and contractors are starting to embed biodiversity metrics alongside whole‑life carbon assessment, using quantified habitat units and standardised biodiversity net gain (BNG) calculators to track performance through design, procurement and delivery. Supply chains are being asked to evidence habitat creation, connectivity and species outcomes in product data sheets and contracts, linking materials choices and temporary works to measurable on‑site ecological change rather than qualitative statements. For geotechnical and civil teams, this signals future schemes where cut‑and‑fill, drainage, earthworks phasing and landscape design must all be optimised against both carbon and biodiversity targets.

Natural England has approved the Stodmarsh stream enhancement scheme under the Habitats Regulations, unlocking nutrient neutrality credits to support several thousand new homes around Ashford, Kent. The scheme centres on watercourse and wetland improvements in the Stodmarsh catchment to offset additional nitrogen and phosphorus loads from new foul drainage. Planners, drainage designers and geotechnical teams will need to integrate on-site attenuation, SuDS and connection strategies that align with the credit conditions tied to the Stodmarsh enhancement works.

The Metals Company’s NORI and TOML subsidiaries have submitted 2013–2022 exploration data from the eastern Clarion‑Clipperton Zone to the ISA’s DeepData system, including 777 equipment deployments, over 4,800 environmental samples, 76,000 biological records and 69,185 geochemical data points from depths beyond 4,000 m. The dataset now accounts for roughly one‑third of all CCZ entries in DeepData and 54% of biological records in the OBIS‑ISA node, positioning it as a key reference for Environmental Impact Assessments. TMC argues this evidence base is sufficient to start monitored commercial nodule collection, despite ongoing calls from NGOs for a moratorium.

Construction’s role in more than one-third of UK carbon emissions is widely acknowledged, but its contribution to acute silt pollution from earthworks, dewatering and runoff from haul roads and stockpiles is still largely overlooked. Fine sediment washed from sites into watercourses can smother spawning gravels, clog culverts and foul SuDS assets, often breaching Environment Agency permits and triggering costly stop-work notices. The piece calls for more rigorous use of silt fences, settlement lagoons and lamella clarifiers, plus better phasing of bulk earthworks to keep disturbed areas and exposed cohesive soils to a minimum.

FI Real Estate Management has been fined £40,000 at Caernarfon magistrates court for unlawfully demolishing buildings on the Peblig Industrial Estate, Caernarfon, that contained bat roosts for three species identified in a 2023 survey. The works proceeded in September 2024 without the required European Protected Species Licence from Natural Resources Wales and before an acceptable replacement bat house design had been agreed with a senior biodiversity officer. The conviction under the Conservation of Habitats and Species Regulations 2017 and the Wildlife and Countryside Act 1981 reinforces that demolition and redevelopment programmes must integrate protected species licensing into design and sequencing.

The UK Department for Energy Security and Net Zero has launched a pilot scheme to test non‑pipeline CO₂ transport options to support wider Carbon Capture, Utilisation and Storage deployment beyond fixed trunk lines. The programme will examine road, rail and ship-based movement of captured CO₂ from dispersed industrial sites to storage hubs, targeting clusters that are uneconomic or technically challenging to connect by high-pressure pipeline. For civil and geotechnical engineers, this signals future demand for modular loading terminals, interim storage tanks and upgraded pavements and rail sidings designed for dense liquid CO₂ logistics.

Egis has appointed Afshan Rasheed to lead a new UK environmental consultancy practice, positioned alongside its existing energy, water and transport teams. The unit will deliver environmental impact assessment and wider environmental services across Egis’s major infrastructure and engineering portfolio, embedding sustainability criteria from early optioneering through to construction delivery. Rasheed, who has previously held senior roles at major engineering consultancies, is tasked with scaling specialist environmental capability and building high-performing, multidisciplinary teams across the UK business.

Natural Resources Wales and the Coal Authority’s Mining Remediation Authority used a PDG helicopter to place 109 bags of stabilisation material along the Nant y Bai riverbank at Nant y Mwyn lead mine, Carmarthenshire, where about 300m³ of spoil was at immediate risk of being washed into the river. The airlift avoided haul roads and heavy plant, limiting ground disturbance and allowing follow‑up hand work to protect rare grassland around the site. Reducing severe spoil erosion is expected to cut cadmium and zinc loading to the Afon Tywi, currently elevated for up to 25 km downstream.

Saudi Arabia is overhauling waste management under Vision 2030, with the National Center for Waste Management (MWAN) targeting 94% diversion of municipal solid waste from landfill and 100% treatment of hazardous and medical waste by 2035. The strategy includes expanding engineered sanitary landfills, waste-to-energy plants and construction and demolition recycling facilities, alongside stricter permitting and data systems for industrial waste streams. For geotechnical practitioners, this signals rising demand for landfill lining systems, leachate control, gas capture infrastructure and brownfield remediation expertise across multiple regions.

Advance Green Futures has begun a 268-hectare restoration of the former Potland Burn mining site in Northumberland to create a large habitat mosaic and long-term biodiversity management area. The scheme is being structured to generate a tradable bank of biodiversity net gain (BNG) units for local developers needing to meet mandatory BNG requirements on constrained sites. For civil and housing projects in the area, this offers an off-site BNG route that could materially influence land valuation, masterplanning, and consenting strategies.

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.

Sponge city strategies are gaining momentum in the UK as Ciwem’s recent Sponge Cities briefing note calls for widespread deployment of nature-based, water-retentive urban design. The concept centres on retrofitting streets, roofs and public spaces with permeable pavements, rain gardens, swales and green roofs to attenuate stormwater, reduce combined sewer overflows and manage surface water flooding. For civil and geotechnical engineers, this signals growing demand for SuDS-led masterplanning, hydraulic modelling of blue–green corridors and revised pavement and subgrade specifications to accommodate higher infiltration and storage.
