BHP and GCMD trial multi-feedstock B100 blend in an existing supply chain in International Shipping News , Shipping: Emission Possible 04/06/2026 BHP and the Global Centre for Maritime Decarbonisation (GCMD) have blended biofuels from two distinct feedstocks—used cooking oil and waste animal fats —and introduced the lower-emissions marine fuel into a BHP-chartered bulk carrier as part of a pilot project. The BHP and GCMD pilot will assess how biofuels from multiple feedstocks can be blended, handled, and introduced under real-world operating conditions using existing used cooking oil bunkering infrastructure. At the same time, insights from this pilot will help identify solutions to challenges related to fuel quality, handling, traceability, and onboard vessel performance. Biofuels for global shipping today rely heavily on used cooking oil – a feedstock whose availability is approaching its projected limits. Biofuel from waste animal fats presents a promising option to expand the supply of lower-emissions marine fuels. The outcomes of the pilot are expected to shed light on the practical steps to integrate biofuel blends from different feedstocks into existing supply chains. The diversity of biofuels will provide shipowners and operators with greater flexibility to optimise fuel procurement based on cost, availability, and lifecycle emissions performance. Biofuels derived from different feedstocks can exhibit varying properties that may impact operations, including potential corrosion from oxidation, fuel system clogging caused by wax formation, which this pilot aims to assess. The pilot will trace and verify the biofuel blend’s integrity aimed at bolstering confidence in emissions reductions reporting. The pilot will also provide insights into how robust tracing can support future marine fuel supply chains where biofuels from multiple feedstocks with varying lifecycle greenhouse gas emissions footprints are blended together.
