Beyond that point, there are no restrictions for dumping untreated, raw sewage in U.S. ocean waters. There are a few places like Puget Sound, California, and most of New England where no-dumping zones have been created but everywhere else, sewage can be dumped. And their smokestacks must be cleaned to remove the harmful elements from the exhaust. So cruise ships have implemented using scrubbers to “clean” their dirty fuel air emissions.
How Do Cruise Ships Eliminate Human Waste?
It’s estimated that an average cruise line dumps around 30,000 gallons of sewage into the ocean each day. Larger ships will be above this average, but specific figures are never released. But modern cruise lines are wising up to their impact on the planet – and their impact on their profits if they don’t listen to the growing clamour from guests for ships to become more environmentally friendly.

All of this waste is packed with germs and junk, which, if tossed directly into the ocean, can definitely harm its ecosystem. Fortunately, rules and systems are in place to handle this procedure correctly. Older ships have in the past dumped human waste into the ocean once the ship was 12 nautical miles away from port, however this is a rare occurrence today, especially among the major cruise line operators. Filtered water on a cruise ship is not recycled toilet water, or any other water from the ship.
Do cruise ships release human waste into the ocean?
Operating in ecologically sensitive areas, like the Norwegian World Heritage Fjords, requires strict adherence to environmental regulations. Cruise ships must meet specific criteria regarding fuel sulfur content, nitrogen oxide emissions, water discharge from scrubbers, incinerators, black and grey water treatment, and anti-vapor plume devices. The Advanced Wastewater Treatment System (AWTS) is the most environmentally friendly procedure – using multiple processing stages to remove all the pollutants. This now “purified wastewater” is then either reused on the ship (not for drinking purposes) or responsibly discharged into the ocean or at a port facility.
“That’s a significant carbon issue if we’re buying food that we’re not using,” Burke said. With only a minibar in my stateroom and food always at my beck-and-call, it seemed impractical. Despite the fact that they’re designed to be fully leak- and odor-proof, strategically positioning them inside the ship’s off-limits areas reduces the dangers of any accidents. About three tons of solids left from the original 1,200 tons of waste per day is incinerated or contained until it can be offloaded.

Do cruise ships launch human waste into the ocean?
These systems rely on a combination of physical filters, chemical treatments, and even biological processes that can break down and treat human waste. The wastewater treatment systems cruise ships separate solid waste from liquid waste, then they disinfect and treat the water. 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.
In addition to harming the environment with these waste products, the cruise ships themselves can also have a negative impact on surrounding ecosystems purely due to their enormous size. Today, however, there are really strict international maritime laws that cruise ships must abide by due to growing concerns over marine pollution. The kind of human sustenance cruise ships discharge is not typically part of fish and other aquatic creatures’ diets, and introducing it can disturb complex food webs, according to Keoleian. Cruise ships conceal and eradicate disagreeable odors from human waste by utilizing hermetic holding tanks. Whereas cruise ships put a big quantity of effort into utilizing recyclable supplies, meals waste and sure types of packaging have to be saved and handled correctly.
Is The Filtered Water On A Cruise Ship Recycled From Toilet Water?
Presently, 70% of the CLIA’s oceangoing cruise line fleet capacity relies on AWTS, marking a 5% increase over 2019. In the past, cruise ships would dump untreated waste into ocean waters, and there may be some older cruise lines that still do. Solid waste, which includes any garbage and other discarded materials not considered hazardous, can be incinerated on board or brought ashore to be landfilled or incinerated. On a cruise ship, these types of wastewater can be collected and stored in ballast tanks before both being treated separately onboard the ship, as we have outlined below.

How Cruise Ships Follow Environmental Standards
Meanwhile, Norwegian Cruise Line says it enforces a zero-tolerance policy for any items thrown overboard. However, passengers soon realized the toilets were not flushing, which is a huge problem on a ship with about 4000+ people onboard. There are adequate suppliers of fresh water on a cruise ship when it disembarks to last the entire journey and more.
One of the most important aspects of waste management on cruise ships is the disposal of human waste. Let’s delve into this process and understand how cruise ships handle and get rid of human waste. It is either discharged into the water in designated areas of the ocean or released onshore into the local water treatment system. Before we get into the methods and procedures cruise ships use to get rid of human waste, it is useful to briefly explain how human waste is stored.
In addition to heavy filtration processes and settlement chambers, cruise ships use chlorine and a specialized combination of aerobic bacteria to break down and treat human waste. Cruise ships hide and eliminate unpleasant odors from human waste by using airtight holding tanks. They also use specialized ventilation systems that make use of activated carbon filters. Black water is a term used to describe human wastewater within the maritime world, including by the cruise industry. Water that has come in contact with human feces, urine, or toilet paper is deemed black water.
Cruise strains should pay sure charges to eliminate their wastewater in port. Native authorities’ charges assist to subsidize the prices related to treating further wastewater. Sewage disposal should always be done far away from land as the sewage may still contain harmful substances like viruses, pathogens, bacteria, and even metals. If you are part of this statistic, chances are you have experienced at least a passing moment when you wondered what really happens to your poop when you flush the toilet. That can mean simply wasting less food when they have a meal on board, and being judicious about what food items they pick.
