The activities of such ships are regulated and scrutinized by international protocols and standards including measures to protect marine resources in terms of waste segregation and disposal. However, there are lapses and overlaps because implementation of such protocols and standards vary from one area of jurisdiction to another.Do you want to learn more?

Cruise ships in particular represent a minute portion of the entire shipping industry. However, the nature of the cruise ships carrying people around, entertaining them while they are aboard the ship, make them a large-scale threat to nature. These ships carry a large number of passengers and crew such that an equally large volume of wastes including human refuse are produced. Aside from the hazardous and toxic wastes, cruise ships also emit air pollutants. Such wastes, if not treated and disposed properly have the potential to totally eradicate aquatic life. Furthermore, as these ships concentrate on a certain route and visit the same ports repeatedly, the cumulative effects result to a large significance.
How are human wastes treated? Both commercial and recreational vessels are required by laws to be installed with toilets with marine sanitation devices which are primarily designed to prevent the discharge of untreated sewage. Treatment system generally provide for the treatment, disinfection and sludge formation and are effective in removing pathogens that cause water-borne diseases, suspended solids, oils, greases and particulate metals that deprive living marine life of oxygen. After treatment, such wastes can be emptied into the ocean depending on the designated distance from the shore and varies from one state to another because some states totally prohibit the release of any form of treated wastes into their area of jurisdiction.
How and where do cruise ships dispose hazardous wastes? Because of certain protocols, cruise ships cannot just empty their tanks or waste treatment facilities’ outlets and release toxic wastes wherever and whenever they want as specific distances offshore for the discharge of specific wastes apply. Certain laws also prohibit the discharge of hazardous wastes, bilge water, solid wastes, oil and grease into the waters. Furthermore, proper storage of such wastes also applies until they are offloaded for disposal in accordance with existing laws. Furthermore, laws mandate that oil separator must be available in accordance to every state’s protocol.
