Kawasaki Kisen Kaisha Ltd has conducted a trial use of marine biofuel which was supplied by global integrated energy company bp on car carrier “POLARIS HIGHWAY". “K" LINE signed a deal for marine biofuel supply with bp. The marine biofuel was delivered to the vessel at the Dutch port of Flushing on Nov 6th, 2021. After leaving Europe Emission Control Area, the vessel conducted the trial use of the marine biofuel.Biofuels are made from renewable organic resources like biomass. Therefore, although C02 is emitted after its combustion, those emissions are compensated with the C02 absorbed during the growth of the biogenic sources used as raw materials. Furthermore, for its production, waste and residues that need to be disposed of can be reused. Some examples are Used Cooking Oil collected from restaurants and residential households and animal fats. This will avoid the use of raw materials that compete with food or feed market. Both the biofuels feedstocks origination and its production along the supply chain are sustainability certified following the criteria of international recognized standards so its generation and traceability are guaranteed by independent third party, ultimately contributing to deployment of biofuels as an environmentally friendly alternative to fossil fuels around the world.
