Can Cruise Ships Dump Trash?

Cruise ships are subject to strict regulations when it comes to waste disposal, and dumping trash in the ocean is strictly prohibited. However, each ship must follow specific requirements when disposing of waste, according to the EPA. Water on board is a highly valued asset, and it is separated into gray water from showers and sinks, and black waste from ships. It is legal to dump sewage and food waste into the sea, but U.S. law requires cruise ships to treat waste within about 3.5 miles of shore. Beyond that, there are no restrictions on dumping polluted sewage.

Cruise ships store their waste on board until they can dump it in the oceans. They are required to treat waste within about 3.5 miles of shore. Most ships either unload their solid waste to be disposed of in traditional waste facilities on land or they incinerate it. The ships offload trash in ports or face massive fines. There has been a recent story about companies in port doing some illegal activities.

Cruise ships also dump harmful fuel waste into the oceans. Some waste streams appear to be well-regulated, such as solid wastes (garbage and plastics) and bilge water. While ships can decide whether to discharge at sea or within a port, most waste from scrubbers is dumped as it is generated. Globally, cruise ships contribute significantly to the pollution of the oceans.

Are cruises worse for the environment than planes?

Taking a seven-day cruise is more than three times as carbon-intensive as flying and staying abroad.

With new research revealing that 214 cruise ships emitted four times as much sulphur as one billion cars last year, Energy Monitor compares the environmental footprint of a cruise holiday with flying to a similar destination.

Cruises in Europe emitted more sulphur than one billion cars – 4.4 times more cars than there are on the continent – according to a June 2023 report from Brussels-based NGO Transport & Environment (T&E).The NGO finds that cruise ship pollution at Europe’s busiest ports has returned to pre-pandemic levels, with sulphur oxides reaching 509 tonnes (t) in 2022, an increase of 9% compared with 2019 levels, while methane emissions increased fivefold during this period, to 7,804t.

This is because the total number of cruise ships on European waters increased from 173 in 2019 to 214 in 2022, outweighing potential emissions reductions from various policies introduced at industry and EU level in recent years, such as the 2020 Global Sulphur Cap imposed by the International Maritime Organization, reducing the maximum content of sulphur in fuels from 3.5% to 0.5%.

What is the most common crime on cruise ships?

Sexual assault Since 2015, sexual assault has been the most reported crime on cruise ships, with more than 450 cases reported between 2015 and 2022, Insider wrote.

Cruises can be enjoyable vacation experiences, what with all that unending food and entertainment. But spending days or longer in an isolated vessel in the middle of the ocean is not diverting for all passengers. Sexual assault is the highest reported cruise ship crime, and the numbers are worsening. Many have also accused cruise companies of covering up incidents of sexual assault rather than protecting the crimes’ victims.

Do cruise ships have jails?

…and a jail. There are no police officers on cruise ships, but most vessels have small jails known as the brig, and unruly passengers could find themselves locked up if the ship’s security team determines that they have violated the cruise line’s code of conduct.

The brig, usually a bare-bones room with a bed and bathroom facilities, does not have iron bars like a traditional jail cell. It is used to detain guests who commit serious crimes like assault or possession of illegal substances. Drunk and disorderly passengers may be put under “cabin arrest,” meaning they cannot leave their cabin without a security escort.

Depending on the circumstances, most passengers put in the brig will stay there until they can be handed over to law enforcement officials.

Do cruise ships dump their waste at sea?

Can cruise ships dump waste at sea?. Yes. It’s quite legal to dump sewage and food waste into the sea. 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 sewage is not just human waste, but also contains chemicals, pharmaceuticals, bacteria, viruses, and heavy metals that are not naturally present in the ocean. Cruise ships don’t have the resources or the facilities to filter out many of these toxic substances. They end up in the habitats of many coastal animals from otters to dolphins to whales, leading to reproductive problems, illness and population decline.

How wasteful are cruise ships?

To the cruise ship industry, a key issue is demonstrating to the public that cruising is safe and healthy for passengers and the tourist communities that are visited by their ships. Cruise ships carrying several thousand passengers and crew have been compared to “floating cities,” in part because the volume of wastes produced and requiring disposal is greater than that of many small cities on land. During a typical one-week voyage, a large cruise ship (with 3,000 passengers and crew) is estimated to generate 210,000 US gallons (790,000L) of sewage; 1million US gallons (3,800m3) of graywater (wastewater from sinks, showers, and laundries); more than 130 US gallons (490L) of hazardous wastes; 8 tons of solid waste; and 25,000 US gallons (95m3) of oily bilge water. Passengers can singlehandedly produce up to 7.7 pounds of waste in a single day aboard a cruise ship. Those wastes, if not properly treated and disposed of, can pose risks to human health, welfare, and the environment. Environmental advocates have raised concerns about the adequacy of existing laws for managing these wastes, and suggest that enforcement of existing laws is weak.(citation needed)

A 2000 Government Accountability Office (GAO) report focused attention on problems of cruise vessel compliance with environmental requirements. GAO found that between 1993 and 1998, foreign-flag cruise ships were involved in 87 confirmed illegal discharge cases in U.S. waters. A few of the cases included multiple illegal discharge incidents occurring over the six-year period. GAO reviewed three major waste streams (solids, hazardous chemicals, and oily bilge water) and concluded that 83% of the cases involved discharges of oil or oil-based products, the volumes of which ranged from a few drops to hundreds of gallons. The balance of the cases involved discharges of plastic or garbage. GAO judged that 72% of the illegal discharges were accidental, 15% were intentional, and 13% could not be determined. The 87 cruise ship cases represented 4% of the 2,400 illegal discharge cases by foreign-flag ships (including tankers, cargo ships and other commercial vessels, as well as cruise ships) confirmed during the six years studied by GAO. Although cruise ships operating in U.S. waters have been involved in a relatively small number of pollution cases, GAO said, several have been widely publicized and have led to criminal prosecutions and multimillion-dollar fines.(citation needed)

In 2000, a coalition of 53 environmental advocacy groups petitioned the Environmental Protection Agency (EPA) to take regulatory action to address pollution by cruise ships. The petition was amended in 2000 to request that EPA also examine air pollution from cruise ships. The petition called for an investigation of wastewater, oil, and solid waste discharges from cruise ships. In response, EPA agreed to study cruise ship discharges and waste management approaches. As part of that effort, EPA issued a background document in 2000 with preliminary information and recommendations for further assessment through data collection and public information hearings. The agency released its final Cruise Ship Discharge Assessment Report in 2009. The report summarized findings of recent data collection activities, especially from cruise ships operating in Alaskan waters.

What happens if someone dies during a cruise?

Depending on the cruise ship’s itinerary, bodies are stored ready to be disembarked at the next port or released to the relevant services on home turf if the ship’s course is coming to an end – an easier result for bereaved loved ones ready to start making arrangements.

So, what does our avid sailor think of the “ice cream party” rumour?

“I’ve worked at sea now verging on 10 years, and this is a rumour that goes around. On the ships that I’ve worked on (large cruise ships), that would never be the case.”

Does human trafficking happen on cruise ships?

While hotels and motels can be especially attractive locations for all forms of human trafficking, it is also important to note that human trafficking occurs at sporting events, theme parks, on cruise ships, and in many other areas of the tourism industry.

Where do cruise ships dump food waste?

For solid foods that are harder to break down, such as bones, animal fats, and skin from fruits and vegetables, Carnival Corporation recently added dehydrators—there are more than 60 in the Carnival fleet of over 85 ships. The dehydrators use heat to remove excess water from leftover food, producing a mostly dry mass that looks like coffee grounds, which can be easily offloaded on shore. Carnival Corporation says the dehydrators can reduce the amount of food waste offloaded by up to 90 percent. While the odorless grounds are currently sent to landfills, there are plans to see if they might be repurposed by other companies, perhaps burned as a sustainable energy source or used as a fertilizer.

The results. With the food waste management technology and other measures, Carnival Corporation says it has accomplished a more than 40 percent reduction in food waste per person, relative to a 2019 baseline, and is already ahead of its 2025 goals. The company is targeting a 50 percent reduction per person, relative to the 2019 baseline, by 2030.

Are cruise ships bad for the environment?

A daily cruise trip averages 700-1000 pounds of carbon emissions, much higher than flying, driving, or a traditional ‘land’ vacation. Additionally, the sulphur dioxide emissions from a single cruise ship can equal the emissions from 13.1 million cars per day, exacerbating air pollution and acid rain.

Data shows that large cruise ships can burn up to 250 tons of fuel daily, producing substantial CO2 emissions. Primarily, bunker fuel, the dirtiest fuel, exacerbates the environmental damage, emitting considerable amounts of black carbon, sulfates, and other harmful chemicals​.

When considering the impact per usage, vacationers generate eight times more carbon on a cruise ship than on land. A week-long journey on a cruise ship for one passenger can result in over 200 kilograms of CO2 emissions, significantly higher than many other forms of travel.

How unsustainable are cruises?

Cruise ships are known to be heavy carbon emitters. A medium-sized cruise ship emits greenhouse gases equivalent to those of 12,000 cars, and it could dump over 1 billion gallons of untreated sewage into the ocean.

For instance, during the six-month cruise season, a ship sailing from Seattle to Alaska emitted 1.1 million tons of CO2 to 559,414 passengers. This data indicates that the cruise industry can generate more than a million tonnes of garbage annually.
