Sewage emissions
DFDS' environmental policy
DFDS’s ships are fitted with biological cleansing units that biodegrade the sewage generated by onboard water consumption. The sewage is then collected in tanks and later discharged away from coastal and particularly sensitive sea areas, which minimises the impact on the marine environment.
As appropriate units are set up to receive the waste, and as improved cleansing and storage facilities are developed on new ships, DFDS expects to introduce new procedures, including pumping sewage onshore.
