IMO mulls scrubber wastewater discharge limits

摘要

Shipping classifcation society DNV GL believes the Interna- tional Maritime Organisation (IMO) is planning to target the discharge of wastewater from scrubbers. Exhaust gas cleaning systems, known as scrubbers, allow vessels to keep burning 3.5pc sulphur marine fuel oil despite the IMO’s 0.5pc sulphur cap, which came into force on 1 January. Wastewater from open-loop scrubbers can be released into the sea and some environmental groups have criticised the IMO for allowing scrubbers after the 0.5pc sulphur cap.
