What do cruise ships do with food waste?

All of that waste is either processed via biodigesters or dehydrators, or offloaded on shore. Some of the company's ships have long had dehydrators, which squeeze the water from food waste and lighten the load that can be taken to landfills, compost sites or waste-to-energy facilities.

During a typical one-week voyage, a large cruise ship (with 3,000 passengers and crew) is estimated to generate 210,000 US gallons (790,000 L) of sewage; 1 million US gallons (3,800 m3) of graywater (wastewater from sinks, showers, and laundries); more than 130 US gallons (490 L) of hazardous wastes; 8 tons of solid ...

U.S. law requires cruise ships to treat waste within about 3.5 miles of shore—but beyond that, there are no restrictions on dumping polluted sewage and graywater. Researchers have estimated that over a billion gallons of sludge made from excrement and food scraps are released into the ocean every year by cruise lines.

The kitchens are extra enormous. A ship that carries 3,500 passengers uses 600 pounds of butter per day, 250,000 eggs per week, and 170,000 pounds of fresh fruits and vegetables per cruise. Naturally, there are more hands on deck in the kitchen too.

They won't run out of water obviously but, eventually, the ship will sink unless corrective countermeasures are taken. That's because the freshwater from a cruise ship faucet is slightly less dense than the salt water in the surrounding ocean.

There are two ways to clean the bottom of a cruise ship. The first way is to dry dock the ship and clean it from the outside while undergoing other maintenance. The only downside to this method is how much it costs. When the vessel is dry-docked, it is expensive for the cruise line.

Shipboard potable water (drinking, bathing, whirlpools, etc.) either comes from a shoreside water treatment plant or is generated on board from seawater via Reverse Osmosis systems or Evaporators. Swimming pool water is typically seawater.

Approximately 40% of the average cruise ship sits below water. The larger or higher the ship, the less of it is in water. This may seem counterintuitive, but this is how math and physics work out!

Thankfully, very few cruise ships have actually sunk in modern history. Even so, the Titanic's sinking impacted maritime law so much that there are more than enough lifeboats for all passengers and crew onboard any given sailing. Within the last 111 years, over 20 cruise ships and ocean liners have sunk.

Diesel Electric. New cruise ships feature diesel electric propulsion. So rather than being connected to the propeller shafts, the main engines are connected to large generators in order to produce electricity. This electricity is sent to electric motors, which powers the propellers and moves the ship.
