Where Does All The Waste Go On A Cruise Ship
Answer 1 of 19.
Where does all the waste go on a cruise ship. A separate initiative introduced on Viking Line cruise ferries is conversion of cruise ship food waste into biogas. It wasnt so long ago that sewage was thrown overboard via storm valves attached to the sides of the ship. As the cruise ship industry continues to expand there is an increasing concern about the environmental impacts of cruise ship discharges.
FOE also cites data from the Environmental Protection Agency EPA which shows an average cruise ship with 3000 passengers and crew produces about 21000 gallons of sewage a day enough to fill 10. Anything which is discharged into the sea goes through rigorous treatment first. All cruise ships fall under international maritime law.
We went inside the secret crew-only deck of Royal Caribbeans Symphony. Federal law requires that cruise ships only dump treated wastewater if they are within three nautical miles of shore. All glass and plastic bottles etc.
Waste water is the second biggest part of onboard waste. Ships can hold their sewage until returning to shore. A common misconception is that once a ship is out in the open ocean they dump human waste into the water.
Waters are flagged under foreign nations. Some cruise lines press the food waste in a giant trash compactor dry it and then burn it to produce hot water for your shower. Calvin Ungs answer is pretty complete in addition it could be interesting to know what happens to the rest of the wastegarbage.
Bilge water water that collects in the lowest part of the ships hull and may contain oil grease and other contaminants. On ships are crushed and recycled onboard and often sold in port to recycling companies however in some countries such as Australia the ships have to pay just to get the recycled material moved off the ship. The ships waste incineration room is manned twenty four hours a day by crew members who differentiate glass based on its color.
