“The FOE report paints a contrasting picture to the environmentally conscientious one offered by the cruise lines themselves,” said Mark Beavis, Managing Director of ACO Marine. “That 40% of cruiseships are still using wastewater treatment technology developed in the 1980s suggests that some of these cruiseships are unable to meet current regulatory requirements. Certainly some of these vessels will be incapable of meeting the more stringent requirements set out in MEPC.227 (64), which limits the amount of phosphorous and nitrogen discharged in treated effluent.”
Beavis added: “With an increasing trend for expedition-type cruising in ecologically sensitive areas, it is paramount to environmental conservation that the cruise sector adopts wastewater technology capable of helping to prevent the nitrification of our seas.” While Friends of the Earth continues to push the U.S. Environmental Protection Agency to update its sewage treatment standards under the Clean Water Act, the environmental campaigner noted that an average cruiseship with 3,000 passengers and crew produces about 21,000 gallons of sewage and about 150,000 gallons of grey water each day.
