Green Marine International is pleased to welcome Sulnox Group Plc to its growing network of partners dedicated to advancing sustainability in the maritime industry. With an approach rooted in science, proven in the field, and focused on what works today, Sulnox offers solutions to improve vessel efficiency by enhancing fuel combustion.

Its core product, Sulnox Eco™, is an organic, drop-in fuel conditioner compatible with the full range of marine fuels, including Very Low Sulphur Fuel Oil (VLSFO), High Sulphur Fuel Oil (HSFO), Marine Diesel Oil (MDO) and marine biofuels. Verified as compliant with ISO 8217 by Veritas Petroleum Services and Lloyd’s Register, it’s also reported to enhance renewable fuels like Hydrotreated Vegetable Oil (HVO) and Fatty Acid Methyl Esters (FAME).

Sulnox Eco is used in more than 40 countries, supported by strategic partners including Drew Marine and Technava, and with global manufacturing through Nouryon.

By joining Green Marine International, Sulnox is reinforcing its commitment to sustainability by providing participants with a solution to address increasing regulatory and cost pressures, delivering benefits such as average fuel savings of around 5% and measurable reductions in CO₂, NOx and particulate matter. All without new engines, retrofits or capital expenditure.
