Cruise ship trash disposal. Cruise ships which are often hundreds of feet long and carry thousands of passengers and crew have been compared to floating cities. As a result all of those millions of passengers and crew members dining and defecating and showering on the oceans have left filthy discharges in their wake. The 6600 passengers on board the worlds largest cruise ship produce a lot of trash.

During a typical one-week voyage a large cruise ship with 3000 passengers and crew is estimated to generate 210000 US gallons 790000 L of sewage. There are separate teams to deal with each incoming recyclable. The dumping of waste at sea is controlled by the six annexes of the MARPOL convention to which most nations are signatories.
