Usage of Scrubber in the Port of Hamburg:
The convention on the collection, deposit and reception of waste generated during
navigation on the rhine and other inland waterways (CDNI) regulates the discharge of
wash water from scrubber in inland waterways by clearly defining a prohibition of it.
Therefore, the discharge of wash water from a scrubber into the river Elbe and in the
Port of Hamburg is strictly prohibited.
According to the national water rights (Federal Water Act) an exemption from the prohibition
is not possible. The contamination of wash water from scrubber systems is too high that a
discharge approval cannot be permitted.
It is possible to dispose closed-loop wash water and solid scrubber waste for a fee at the
port reception facilities in Hamburg. The scrubber waste can be declared with the ship’s
waste notification form (https://www.hamburg.de/marpol/info/) before arriving at the Port
of Hamburg. Beforehand the first disposal in Hamburg, a wash water sample can be
requested in order to determine the toxicity and the type of disposal accordingly. The waste
can be disposed from either water or land side. Depending on the toxicity, the scrubber
waste becomes incinerated or recycled in a processing plant.
