Wash Water News

The discharge of scrubber water from ships out to 22km (12 nautical miles) from the Danish coasts will be prohibited by law. The ban will come into effect on July 1, 2025, for ships with scrubbers in open operation, where the wash water is discharged into the sea. For ships with scrubbers in closed operation, the ban on water discharge will take effect on July 1, 2029.The Ministry of Environment has stated that scrubber water has contributed to excessive levels of a number of heavy metals and tar substances such as lead, cadmium, anthracene and benz(a)pyrene in the marine environment.
