And many cruise ships lack the sewage treatment facilities to adequately filter out toxins. Both the EPA and the USCG say they do not tally the amount of waste disposed by cruise ships. It’s illegal according to U.S. and international maritime law, but many companies have proven they don’t care, and have been caught illegally spewing plastic into the sea. Carnival Cruise Lines was found dumping food mixed with plastic waste into the waters of the Bahamas.

What is grey water?
Now, she helps over 1 million people per month to plan their perfect cruise holidays. Beyond wastage, cruise lines are also looking at other environmentally-friendly technologies that could be better for the environment and either be more profitable in future, or ensure that people are still happy to cruise. Fuel technology advancements, such as Royal Caribbean’s investment in biofuel, is one of the prominent areas of research.

If this state-level activity were to increase, Congress could see a need to develop federal legislation that would harmonize differences in the states' approaches. The VGP applies to pollutant discharges incidental to the normal operation from non-recreational vessels that are 79 feet or more in length, and to ballast water discharges from commercial vessels of less than 79 feet and commercial fishing vessels of any length. Geographically, it applies to discharges into waters of the United States in all states and territories, extending to the reach of the 3-mile territorial limit.
Other State Activities
The best thing to do is to treat sewage and release it in the deep ocean (paywall). If released near coasts, untreated sewage can contaminate seafood, kill marine animals, and sicken swimmers. The cruise industry is a significant and growing contributor to the U.S. economy, providing more than $32 billion in benefits annually and generating more than 330,000 U.S. jobs, but also making the environmental impacts of its activities an issue to many. One fisherman, Mark Severson, recalls in the summer of 2019 sailing through miles of foamy yellow waters in Petersburg, a small island community about 30 miles from the Canadian border and a popular port along the Alaska cruise route. Since then, Severson and his wife, Karen, have been advocating for stronger monitoring of waste dumping on cruise ships.
Cruise Ship Waste Streams
Once the sewage has been completely processed, it will enter a storage tank until it can be disposed of, either on land or released into the sea at a safe distance from the shore. At this stage, all solid materials will eventually be removed from the sewage, once they have been passed through the first three steps multiple times. The solid matter will be a lot lower in volume than when it first entered the plant, and it will now be incinerated in a low-emission incinerator, minimising the release of harmful chemicals. It may also be stored until it can be disposed of properly when the ship returns to port.
At $89 a Day, This 3.5-Year Cruise Is Cheaper Than Living in Most US Cities
In next week’s post, you can find out how the laundry rooms, the housekeeping, and the kitchens operate aboard a cruise ship. In the reverse osmosis process, a pump pressurizes the seawater and forces its molecules through a semi-permeable membrane. Most dissolved salts, organic compounds, bacteria and suspended solids are larger than the mesh of the membrane and are unable to pass through. “The passengers that love the Alaska cruise do not even realise that the ships are polluting our pristine parts of the world,” he says. Before you take a cruise, consider green travel options instead — or take a look at Friends of the Earth’s Cruise Ship Report Card to see which cruise lines you should adamantly avoid.

Do Cruise Ships Reuse Waste Water?
In the alternative purification process, the H2O is evaporated from the seawater in specially designed evaporators, such as the Wärtsilä Serck Como multi-stage flash (MSF) evaporators in the picture below. Heat from the engine’s cooling water (75-95 ° C) is typically used as a source of heat for the evaporation process. The resulting condensate is then processed depending on the intended use.
Where Do Cruise Ships Dump Their Waste?
This leaves clean, safe and bacteria-free water, which is transferred to a storage tank until it can be discharged. When black water enters the integrated treatment system, it first passes into a bioreactor ‘aeration chamber’ which is filled with bacteria that break down organic contaminants dissolved in the wastewater. If you have been on a cruise ship, you have noticed there is always plenty of uneaten food.
US cruise ships using Canada as a ‘toilet bowl’ for polluted waste
Yes RCCL has been caught and paid a fine of something like $6,000,000,.00. When you get to port you'll see a few big pipes attached to the ship, some are for fuel and the other(s) are for this. The ship has an incinerator, as well as a compactor for processing plastic waste.
Lying on a busy route for cruise ships, the park holds some of the largest rookeries of Steller sea lions in the world. Each spring, more than 1 million seabirds – including 90% of Canada’s tufted puffins and half of the world’s Cassin’s auklets – breed on the island’s cliffs. From the comfort of cruise ships, a typical trip to Alaska offers magnificent views of glaciers and untamed national parks, and visits to quaint seaside towns. For years, these draws have made cruises to Alaska the most booked US holiday.
This report describes the several types of waste streams that cruise ships may discharge and emit. It identifies the complex body of international and domestic laws that address pollution from cruise ships. It then describes federal and state legislative activity concerning cruise ships in Alaskan waters and activities in a few other states, as well as current industry initiatives to manage cruise ship pollution. More than a billion gallons of sewage are dumped into the ocean annually. This sewage is not only full of human waste, but also chemicals, pharmaceuticals, bacteria, viruses, heavy metals, and hazardous waste.
More than 90 percent of those surveyed support a requirement for cruise ships to upgrade their onboard waste treatment facilities to more fully treat sewage before it is released into the sea. Cruise ships are equipped with water treatment systems that clean the human waste (black water) and grey water (water that goes down the sinks and showers), before it gets treated and combined and released back into the ocean. By the time this water is released back into the ocean, it has been cleaned enough to be safe for dumping into the ocean. Once fully treated, this type of non-sewage wastewater can be discharged into some regions of the ocean.
