Olam Agri, Vitol Bunkers wrap up co-processed VLSFO bio-bunkering operation in Singapore

Agri-business Olam Agri on Thursday (20 August) said it successfully completed Singapore’s first bio-bunkering operation with Vitol Bunkers, using Very Low Sulphur Fuel Oil (VLSFO) co-processed with Cashew Nutshell Liquid (CNSL), showcasing a waste-to-energy approach. 

MV Scion Mathilda was supplied with 246.5 metric tonnes (mt) of co-processed VLSFO at the Port of Singapore, comprising 212 mt of conventional VLSFO and 34.5 mt of co-processed CNSL VLSFO. The product was supplied by Vitol Bunkers and procured by Olam Agri’s ocean freight business.

The fuel was subsequently consumed during a voyage from Caofeidian (China) to Rotterdam (Netherlands), followed by a ballast leg from Rotterdam to Barcarena (Brazil). 

Total fuel consumption across the voyage comprised 1,354 mt of VLSFO, 101 mt of MGO and 34.1 mt of co-processed VLSFO. The vessel completed the voyage without any operational remarks, confirming the product’s performance in real-world conditions.

The operation marks a significant step forward in the search for practical, scalable alternatives to conventional marine fuels, and demonstrates that meaningful greenhouse gas (GHG) reductions can be achieved without any change to vessel operations.

Martin Fynbo, Head of Bunkers at Olam Agri’s ocean freight business, said: “The successful deployment of this product, achieving verified greenhouse gas mitigation alongside ensuring operational integrity, serves as a definitive proof of concept. This milestone provides validation to a traditionally risk-averse sector, demonstrating that a previously disregarded bio-product solution can both be operationally viable and sustainable.”

Sherman Yeo, Trading Manager, Vitol Bunkers, said: “This operation proves that co-processed VLSFO can be delivered and consumed at sea without any compromise to vessel performance or operational routine. The mass balance solution we have developed opens up a genuinely new avenue for GHG reduction in marine fuels.”

The co-processed VLSFO carries a GHG intensity of 2.02 gCO2eq/MJ, delivering savings of at least 120 MT CO2eq compared with conventional VLSFO on an equivalent basis. This outcome was achieved with no additional onboard handling or fuel treatment requirements.

Vitol’s co-processing and mass balancing methodology resolves a longstanding challenge in the use of CNSL as a marine biofuel. Direct blending of CNSL has historically been dismissed by the industry due to material compatibility and handling issues. By co-processing CNSL within the refinery stream, Vitol has opened a commercially viable pathway for CNSL to contribute to GHG reduction in shipping.

The co-processed VLSFO used in this operation conforms to RMG380 VLSFO grade and has the same chemical composition and quality as conventional fuel, eliminating the need for additional permissions or special clauses in charter party agreements.

“CNSL, derived as a by-product of cashew processing, represents an underutilised feedstock with genuine potential as a scalable marine biofuel component,” Olam Agri added. 

“This trial demonstrates that with the right processing approach, it can be integrated into existing supply chains without disruption.”
