BHP, GCMD Trialling Lower-Emissions Biofuel for Bulk Carriers

Why It Matters

Demonstrating a viable, lower‑carbon fuel mix helps the shipping industry meet tightening emissions regulations and could unlock new waste‑to‑energy supply chains. Success may accelerate broader adoption of sustainable marine fuels, reducing reliance on fossil diesel and supporting climate goals.

Key Takeaways

• BHP and GCMD test blended biofuel on iron‑ore bulk carrier
• Fuel combines used cooking oil with waste animal fat, cutting emissions
• Trial shows non‑food waste feedstocks can power marine vessels
• Success may speed industry shift to IMO‑aligned low‑carbon fuels

Pulse Analysis

Maritime decarbonisation has become a regulatory priority, with the International Maritime Organization targeting a 40% reduction in greenhouse‑gas intensity by 2030 and a 70% cut by 2050. Traditional marine fuels are carbon‑intensive, prompting ship owners to explore alternatives such as liquefied natural gas, hydrogen, and biofuels. Biofuels derived from used cooking oil have gained traction because they recycle waste streams while delivering lower lifecycle emissions, but their supply is limited by the availability of food‑grade feedstocks. Expanding the feedstock base to include non‑food waste, like animal fats, could dramatically increase the volume of sustainable fuel available for global fleets.

The BHP‑GCMD trial represents one of the first real‑world applications of a blended biofuel that mixes used cooking oil with waste animal fat. The fuel powered a bulk carrier carrying iron ore, a route that typically consumes large quantities of heavy fuel oil. Early data suggest the blend delivers comparable engine performance while cutting carbon emissions by an estimated 10‑15% relative to conventional bunker fuel. BHP’s involvement underscores the mining sector’s growing interest in greening its logistics chain, and GCMD’s expertise provides a credible pathway for scaling the technology across Singapore’s busy shipping lanes.

If the trial proves commercially viable, it could trigger a cascade of investments in collection, processing, and distribution infrastructure for animal‑fat‑derived biofuels. Shipping companies would gain a more diversified, resilient supply of low‑carbon fuel, reducing exposure to volatile oil markets and regulatory risk. Moreover, the approach aligns with circular‑economy principles, turning waste that would otherwise require disposal into a valuable energy resource. As more vessels adopt such blends, the cumulative emissions savings could be substantial, helping the industry stay on track with its decarbonisation roadmap.
