ecological and energy transition, maritime : Enhanced ship waste collection along the Seine corridor

On April 1, 2026, HAROPA PORT signed an agreement with each of the two winners of the call for expressions of interest (CEI) it had launched to support improvements in ship waste collection and to strengthen the environmental performance of port areas along the Seine axis.

These agreements follow the CEI entitled “Improvement of the collection of operational waste and liquid and solid cargo residues from ships in the ports of Rouen, Le Havre and Le Havre-Antifer,” published between late February and late April 2025.

New capacities to strengthen collection along the Seine corridor

The two selected companies, SLOP Normandie and NORMANDY VESSEL SERVICES, both based in Rouen, will enhance the existing ship waste collection services, which currently remain partial depending on the areas and port calls.

These new capacities will enable the collection of various types of waste (liquid and solid) generated by ship operations. Depending on their nature, this waste will be directed towards appropriate recovery channels, such as incineration or recycling.

Support for the ecological transition

This initiative is part of a virtuous approach: reinvesting the revenues generated by the waste fee charged to ships that do not discharge their waste, in order to improve collection systems. HAROPA PORT is the first port to implement this mechanism.

In this context, HAROPA PORT is supporting the selected companies through a subsidy covering 50% of eligible expenses, representing a total amount of €6.6 million.

These investments represent a significant step forward in improving ship waste management along the Seine axis and in strengthening the environmental performance of port areas.
