    BHP–GCMD B100 biodiesel trial: performance and risk notes for iron ore shippers

    June 3, 2026|

    Reviewed by Tom Sullivan

    First reported on International Mining – News

    30 Second Briefing

    BHP and the Global Centre for Maritime Decarbonisation have bunkered a B100 biodiesel blend, derived from used cooking oil and waste animal fats, into a BHP‑chartered bulk carrier on an existing iron ore route. The pilot will test combustion performance, fuel stability and engine compatibility of the multi‑feedstock fuel in a conventional marine diesel system without hardware modifications. Results will inform future large‑scale deployment of drop‑in biofuels across BHP’s dry bulk fleet and similar long‑haul iron ore supply chains.

    Technical Brief

    • Multi-feedstock blend uses only waste-derived lipids, avoiding competition with food-grade vegetable oils.
    • Lubricity and cold-flow behaviour of the mixed-feedstock biodiesel are being monitored for waxing or filter blockage.

    Our Take

    In our database of 1186 Mining stories, BHP features heavily in decarbonisation coverage, with this iron ore supply-chain biofuel trial sitting alongside recent copper-focused initiatives such as renewable power deals at Escondida and Spence, signalling a portfolio-wide emissions strategy rather than a single-commodity effort.

    The collaboration with the Global Centre for Maritime Decarbonisation links BHP’s iron ore logistics to a broader maritime testbed; this could give BHP early operational data on multi-feedstock B100 performance that other bulk shippers in the Pilbara iron ore trade will likely have to catch up on.

    Set against recent reporting that BHP has delayed some Pilbara renewable power projects affecting iron ore operations, progress on marine biofuels suggests the company is prioritising lower-capex, operational decarbonisation levers in the near term while larger grid-scale investments are pushed out.

    Volvo–Boliden autonomous tailings haulage: design and safety notes for mine engineers

    Volvo Autonomous Solutions and Boliden have completed an autonomous haulage project for tailings dam construction at the Garpenberg zinc mine in Sweden, the first deliverable under their 2023 memorandum of understanding. Volvo’s autonomous haul trucks operated on a defined haul road between the open pit and the tailings facility, integrating with existing conventional fleets and site traffic management. The trial provides data on cycle times, berm and ramp design, and interaction rules needed to scale autonomous haulage for future dam lifts and other overburden movements on Boliden sites.

    Cobre Las Cruces PMR under Global Panduro: design and flowsheet notes for engineers

    Cobre Las Cruces S.A.U. has completed its sale from First Quantum Minerals to Global Panduro, controlled by Resource Capital Funds, in a deal valued at up to US$190 million, clearing the way for the Polymetallurgical Refinery (PMR) project near Seville. The PMR is designed to process complex polymetallic ores on site rather than exporting concentrates, shifting the operation from conventional open-pit copper cathode production towards an integrated hydrometallurgical flowsheet. For engineers, the ownership change signals continuity for permitting, plant design and potential underground transition planning at this brownfield Iberian Pyrite Belt asset.

    Epiroc LinkOA AHS quarry order: autonomy retrofit takeaways for mine planners

    Epiroc has secured an order from Heidelberg Materials to deploy its LinkOA autonomous haulage system on driverless haul trucks at an Australian quarry, extending the platform from large open-pit mines into the quarrying and aggregates sector. The project will adapt LinkOA’s mine-proven fleet management, collision avoidance and traffic control capabilities to shorter haul cycles, tighter geometries and mixed-traffic quarry conditions. For quarry operators, this signals accelerating interest in OEM-agnostic autonomy retrofits on existing haul fleets to cut operating costs and manage labour constraints.
