where does all the human waste go on a cruise ship
Cruise ship pollution in the United States Cruise ships generate a number of waste streams that can result in discharges to the marine environment, including sewage, graywater, hazardous wastes, oily bilge water, ballast water, and solid waste. They also emit air pollutants to the air and water. These wastes, if not properly treated and disposed of, can be a significant source of pathogens, nutrients, and toxic substances with the potential to threaten human health and damage aquatic life. Cruise ships represent a small — although highly visible — portion of the entire international shipping industry, and the waste streams described here are not unique to cruise ships. However, particular types of wastes, such as sewage, graywater, and solid waste, may be of greater concern for cruise ships relative to other seagoing vessels, because of the large numbers of passengers and crew that cruise ships carry and the large volumes of wastes that they produce. Further, because cruise ships tend to concentrate their activities in specific coastal areas and visit the same ports repeatedly (especially Florida, California, New York City, Galveston, Seattle, and the waters of Alaska), their cumulative impact on a local scale could be significant, as can impacts of individual large-volume releases (either accidental or intentional).
MS Quantum of the Seas MS Quantum of the Seas is a cruise ship for Royal Caribbean International (RCI) and the lead ship of the Quantum class of cruise ships. The Quantum class surpasses RCI's earlier Freedom-class ships by over 14,000 GT, becoming the second-largest class of passenger ships behind RCI's Oasis class ships on a gross tonnage basis.[1] Quantum of the Seas was delivered to RCI on October 28, 2014[10] and is sailing from Shanghai, China.[11]
