Dutch producer GoodFuels Marine is plotting to supply vessels with biofuel produced from cooking oil, household waste and forest residue using its own Coca-Cola-style secret recipe.

The company has been developing eco-fuels since 2015 and has carried out trial voyages using Norden and Samskip vessels.

CEO Dirk Kronemeijer told TradeWinds their products have undergone two years of testing, but it was not easy finding someone to take a chance on its new heavy fuel oil equivalent.
