MASH Makes has confirmed its upgraded biofuel derived from cashew nutshell liquid (CNSL) is ready for marine applications after successful lab testing. The upgraded fuel addresses reliability and blending issues that have historically limited CNSL's use in shipping.

These issues, including poor blending and polymerisation risks, have been resolved through MASH Makes' proprietary upgrading process, resulting in a stable and clean-burning fuel. The tested blend consisted of 20% upgraded CNSL and 80% VLSFO, evaluated at FVTR GmbH in Germany using a marine-grade single-cylinder research engine. The testing demonstrated clean combustion, no injector fouling, and stable performance across all engine loads.
