    such as the Caribbean
  • Each Cruise Ship can carry up to and more than
    2,500 passengers in one trip
  • These ships are like floating cities and just
    like any city they need to dispose of wastes and
    this disposal of wastes needs to regulated.

2 Regulation Roadblocks
  • Flag of Convenience
  • Ships tend to travel on the high seas

Who Regulates the Industry?

Types of Waste
  • Ballast Water
  • Wastewater
  • Graywater
  • Blackwater
  • Hazardous Waste
  • Solid Waste

Ballast Water
  • Used to maintain ships stability in water
  • Releases water when they increase weight on ship
  • Take up water when they decrease the weight of
    the ship
  • Causes invasion of non-exotic species
  • This water must be released out to sea
  • However most cruises travel along the coast and
    rarely make transoceanic voyages

  • Graywater-waste from sinks, showers, and cleaning
    of the ship
  • Contains detergents, oil, and food grease
  • On a week long cruise up to one million gallons
    can be released into the ocean
  • Blackwater-waste from toilets and infirmaries
  • Up to 21,000 gallons of this waste a day is
    released from the ship

Hazardous Waste
  • Classified as any solid or liquid that can
    threaten human health and the environment
  • IMO and ICCL classify it as the following
  • Waste from photo processing

  • Light bulbs
  • Batteries
  • It cannot be released in any Maritime Zone
  • It is taken on land and recycled and disposed of

Solid Waste
  • Aluminum, glass, paper, cardboard, steel cans,
    incinerator ash, plastics, and kitchen grease
  • Not Easily absorbed into the environment, does
    not biodegrade in a short time in sea water

    unless it is ground less than one inch.
  • Between 12 and 25 nm vessels are not permitted to
    dump plastics, dunnage lining, and packing
    materials that float
  • More than 25 nm from shore ships can dump all
