    BHP multi-feedstock biofuel trials: bunker handling lessons for bulk carriers

    BHP multi-feedstock biofuel trials: bunker handling lessons for bulk carriers

    First reported on Australian Mining

    30 Second Briefing

    BHP and the Global Centre for Maritime Decarbonisation are trialling a marine biofuel blend derived from used cooking oil and waste animal fats on a BHP‑chartered bulk carrier voyage from Australia to China. The pilot focuses on blending, handling and tracing multi‑feedstock biofuels through existing bunker supply chains, using current marine fuel infrastructure rather than dedicated new storage or pipelines. Outcomes will inform fuel specification, engine performance and contamination risk management for large dry bulk vessels on long‑haul export routes.

    Technical Brief

    • Multi-feedstock blend must remain compatible with existing marine engines and fuel handling systems on Berge Lyngor.
    • Trial evaluates cold-flow behaviour and stability of used cooking oil and tallow-derived components during long storage.
    • BHP and GCMD are monitoring injector cleanliness, filter plugging and sludge formation under continuous biofuel use.
    • Fuel traceability work includes segregating and sampling at each bunkering and transfer step in the chain.
    • Operators are checking for water uptake, microbial growth and corrosion risk in conventional bunker tanks and lines.
    • Engine performance data will compare specific fuel consumption and power output against recent conventional voyages on the same route.
    • Emissions measurements focus on CO₂-equivalent, NOₓ, SOₓ and particulate changes relative to baseline heavy fuel oil.

    Our Take

    In our Environmental category, BHP features heavily in decarbonisation coverage, from renewable power at Escondida and Spence in Chile to paused Pilbara solar-and-battery projects, so a marine biofuel trial on Berge Lyngor fits a pattern of testing multiple abatement levers rather than relying on a single pathway.

    The involvement of Australian Mining and the Australia–China operating corridor around Berge Lyngor echoes other recent pieces where BHP’s Australian operations are under scrutiny for delayed Pilbara decarbonisation spend, suggesting that visible trials in shipping may help demonstrate progress while large capital projects are reassessed.

    With South Australian royalties recently highlighted as being driven largely by BHP’s Olympic Dam, incremental emissions cuts in logistics (such as biofuel for ore shipping) are likely to be material for the company’s reported Scope 3 profile even though they sit outside the mine gate.

    Egis appoints Jamie Gleave EIA director: implications for UK infrastructure teams

    Egis has appointed Jamie Gleave as senior environmental impact assessment technical director for the UK, bringing more than 25 years’ experience across energy, transport and water infrastructure, including Wylfa Newydd nuclear power station and National Grid electricity transmission schemes. Gleave previously served as EIA technical director at AECOM, where he led its global EIA technical excellence practice and directed environmental work on the A428 Black Cat to Caxton Gibbet and M42 Junction 6 DCO schemes, acting as expert witness. He will work with UK–Ireland head of environment Afshan Rasheed to build Egis’s EIA, DCO and technical assurance capability.

    United Utilities £900k sewage fine: CSO and storm capacity lessons for engineers

    United Utilities has been fined £900,000 after admitting five environmental permit breaches linked to a major raw sewage discharge on the Fylde coast in June 2023, following failures in its wastewater treatment and overflow control systems. The incident involved untreated effluent bypassing normal screening and settlement processes during storm conditions, leading to prolonged discharge through combined sewer overflows into coastal waters used for bathing. For civil and environmental engineers, the case reinforces regulatory scrutiny on stormwater storage capacity, real-time CSO monitoring, and resilience of ageing sewer networks under intense rainfall events.

    83% of Britain’s cities heat‑vulnerable: design implications for civil engineers

    Eighty-three per cent of Britain’s cities – 59 urban areas – are classed as highly vulnerable to urban heat in new spatial analysis by Ordnance Survey, the Met Office and 4 Earth Intelligence. The dataset combines OS building footprints, surface cover and green space with Met Office temperature projections to map local heat exposure at street-block scale. For civil and geotechnical engineers, this points to urgent retrofit of shading, permeable and high-albedo surfaces, and revised pavement and rail design to cope with more frequent extreme surface temperatures.
