Best Practices for Recreational Water Facilities Onboard Ship

(See endnote 24, pages 55-69 for a detailed discussion on acceptable Best Practices in this area.)

Solid Waste Storage and Disposal

(See endnote 27, Section 5)

Solid waste includes garbage, refuse, sludge, rubbish, trash, and discarded materials and can either be non-hazardous or hazardous. Non-hazardous waste which will be discussed here includes packaging, newspapers, disposables, food waste, plastic, wood, glass, metal cans, incinerator ash, etc. Cruise ships generate large volumes of solid waste. For example, one cruise ship with 2500 passengers and 800 crew members can generate 1 ton of garbage a day. It can also generate thousands of pounds of glass and cans per week as well as a large amount of dunnage, which is packing material to protect and support cargo in the ship’s hold, as well as all the packaging material used around the ship. It is estimated that a cruise ship can generate 70 times more solid waste each day than a cargo ship. Solid waste improperly handled and discharged to the ocean, litter thrown into the water by passengers, or things such as towels, clothing, plastic bottles, cans, etc. blown overboard, create a serious environmental impact on the ocean or fresh bodies of water and may have a detrimental effect on sea life. Plastics are especially a problem since they accumulate on the surface of the water and on beaches. Birds, fish, turtles, and even marine animals may be seriously affected. Garbage can increase the biological oxygen demand and chemical oxygen demand, increase turbidity, and increase nutrient levels in the water. The ash from incineration may be toxic in nature to sea life.
