Starting from January 1, 2025, the Port of Amsterdam will implement a full ban on the use of open-loop scrubbers by ocean-going vessels. This move aims to reduce pollutant emissions and protect the port’s water and soil environment.

A scrubber is an exhaust gas treatment device installed in a ship’s chimney to reduce sulfur emissions. However, open-loop scrubbers discharge polluted wash water directly into the port waters, causing significant pollution to the water and sediment, while allowing ships to continue using high-sulfur fuel oil. In contrast, closed-loop scrubbers collect and store wastewater, preventing direct discharge.

According to the new regulations, ships docked at the Port of Amsterdam will not be allowed to use open-loop scrubbers for discharges starting in 2025. Ships using hybrid scrubbers must switch to closed-loop mode or switch to clean fuel that meets sulfur emission standards (such as marine diesel oil, MGO).

Data shows that in 2023, around 100 ships equipped with open-loop scrubbers visited the Port of Amsterdam. Similar bans have already been implemented in Antwerp, Hamburg, and several ports in France and Scandinavia.

Port of Amsterdam director Milembe Mateyo stated, “This decision will effectively reduce water pollution, promote a cleaner port environment, and support the sustainable development of the shipping industry.”
