Sweden's Stena Bulk has become the latest owner to test out the potential of biofuels.
It is carrying out a trial of the eco-fuel over 10 days on its 50,000-dwt Stena Immortal (built 2016).
The vessel has been bunkered with 250 tonnes of the MR1-100 fuel at Rotterdam.
It is produced from used cooking oil and supplied by GoodFuels of the Netherlands.
