B24 & B30 Marine Bio-Bunker Fuel (Bio-VLSFO)

ISCC-EU certified UCOME blended into VLSFO to Singapore MPA SS 660 / WA 2:2022 and ISO 8217

Marine bio-bunkering has emerged as the premier operational drop-in decarbonization solution for deep-sea container shipping and bulk ocean transport. B24 Bio-VLSFO consists of a 24% by volume blend of second-generation, waste-derived Used Cooking Oil Methyl Ester (UCOME, HS 3826.00) with 76% conventional Very Low Sulphur Fuel Oil (VLSFO 0.5% S, ISO 8217 RMG 380). B30 increases the bio-share to 30%. Under the European Union's FuelEU Maritime Regulation (Regulation EU 2023/1805), commercial vessels calling European ports face mandatory greenhouse gas (GHG) intensity reductions of 2% in 2025, ramping to 6% in 2030, 14.5% in 2035, and 80% by 2050, accompanied by severe non-compliance penalties (€2,400 per tonne of VLSFO equivalent). Burning B24 formulated with ISCC-EU certified Annex IX Part B waste lipids delivers a verified lifecycle GHG reduction exceeding 20% to 22% on a well-to-wake basis, immediately bringing container liners (Maersk, CMA CGM, ONE, Cosco, Evergreen) and Capesize bulkers into full regulatory compliance without engine modification. The commercial trade is concentrated at the Port of Singapore, the world's leading bunkering hub with over 54 million metric tonnes of marine fuel sales. The Maritime and Port Authority of Singapore (MPA) pioneered the regulatory framework through Singapore Technical Reference TR 56, Singapore Standard SS 660, and Provisional National Standard WA 2:2022 for Marine Biofuel Blends. In Singapore, all bio-bunkering transfers must occur via MPA-approved Mass Flow Meters (MFM) to eliminate volumetric discrepancies, with representative MARPOL drip samples taken continuously at the bunker manifold. Quality parameters strictly satisfy ISO 8217:2024 residual marine fuel specifications: kinematic viscosity ≤ 380 cSt at 50 °C, density ≤ 991.0 kg/m³, flash point ≥ 60 °C, and total sediment existent/potential (TSE/TSP) audited to guarantee thermal stability and filterability in shipboard purifiers. CBIL brokers physical B24 and B30 bunker stems and cargo blending parcels in Singapore (Jurong Island / Universal Anchorage), Rotterdam, and Zhoushan, contracting exclusively against named MPA-licensed bunker suppliers and ISCC-EU certified blenders, backed by complete Proof of Sustainability (PoS) mass-balance documentation.
