What Happens To Food Waste On Cruise Ships?

Carnival, a cruise company operating brands like Holland America, Carnival Cruise Line, and Princess Cruises, generates an average of 1.3 pounds of food waste per person daily. However, the amount can vary depending on the line. Food waste is often processed, ground down into tiny particles, and released into the oceans within permitted areas. This waste is sometimes referred to as fish food.

Cruise ships adopt a circular approach, sourcing ingredients locally, reducing packaging waste, repurposing food waste into new products or compost, and segregating food scraps into buckets for incineration. The major source of perishable food waste is from leftovers at meal times, and proper disposal is a concern among environmentally conscious passengers. Food waste may undergo processes such as grinding, maceration, or liquefaction to reduce its volume and facilitate handling and disposal. Some ships have food waste pulverized and discharged, or stored in a waste recycling center.

Food waste is processed via biodigesters or dehydrators, or offloaded on shore. Once on land, it is transported to a facility for processing, which could be a landfill or anaerobic digestion. Once cooked, food must be disposed of, with the easiest way being to liquefy leftovers. If food is taken and not eaten, expired, or wasted, it is chopped up and dumped into the sea.

One of the first steps in managing food waste on cruise ships is segregation, where crew members separate food waste from other types of waste. Food waste is discharged in the ocean when uneaten, and traditionally, food waste onboard was stored through freezing or processed using food pulpers.

Is Royal Caribbean ethical?

We recognize and embrace our responsibility to respect, uphold, and promote internationally recognized human rights standards. Our respect for human rights is enshrined in our Code of Business Conduct and Ethics, which is underpinned by a robust suite of corporate policies and procedures.

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.

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.

What does Carnival do with food waste?

We lead the industry with over 600 innovative food waste biodigesters installed across our fleet, which enabled our ships to organically decompose uneaten food on board in 2023 to just a fraction of the original volume. By “digesting” this leftover food down to a liquid form, it can be sustainably returned to nature.

In addition, we continue to innovate our approach to maximizing waste diversion by installing technologies such as grinders and dehydrators in addition to the more than 600 biodigesters we have installed fleetwide.

These machines build on the effectiveness of biodigesters by enabling the ships to sustainably break down a wider range of food items, including fruit and vegetable rinds, animal fats and other solid foods that are traditionally harder to break down. By the end of 2023, we installed over 60 dehydrators across the fleet to remove excess water from leftover food, reducing waste volume by up to 90%.

Do cruise ships still dump their waste in the ocean?

Do Cruise Ships Dump Sewage?. Yes. To get into a few more specifics than above, the U.S. allows cruise ships to dump treated waste into the ocean if they are within three and a half miles from shore. 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.

How Much Sewage Do Cruise Ships Dump?. 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. And many cruise ships lack the sewage treatment facilities to adequately filter out toxins.

The increased waste in the ocean adds to the problem of pollution and oxygen depletion in the waters. Added nitrogen and phosphorus allow for algae blooms — which can suffocate coral reefs, manatees, shellfish, and fish.

How much food does a cruise ship throw away?

Competitor Carnival says its cruise lines on average. generate 1.3 pounds of food waste per person per day. Their ships have been outfitted with biodigestors, which convert food waste into a liquid.

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.

What happens to wasted food on a cruise ship?

Food waste produced on board is sent to a pulper and pulverized to less than 25 mm, as per international standards, and discharged no closer than 12 nautical miles from land.

Where does cruise food waste go?

Including what’s left over on passengers plates eventually gets sucked into. Food pulpers and then travels into the pipes underneath where passengers dine. So this is where all the food waste.

What do cruise ships do with leftover buffet food?

Traditionally, the leftover food on a cruise ship is ground by food pulpers, then pulverized in a paste or slurry to be stored until the ship reaches land. Once the waste arrives on land, it is transported to a facility for processing. These facilities could be a landfill or an anaerobic digestion plant.

What can cruise ships do about their food waste?. The LFC biodigester is an onsite solution that digests the food waste onboard the ship, leaving behind grey water that can be safely discharged at sea. Alternatively, the waste water can be processed in the ship’s STP (sewage treatment plant) system. The LFC biodigester is a machine that uses natural microorganisms to break down organic material, resulting in a liquid that can be easily discharged. It’s a great solution for cruise ships because it eliminates the need to transport the waste off the ship, reducing the carbon footprint associated with waste disposal.

Furthermore, the LFC biodigester has low utility usage and different models can process up to 6000 kg (13,200 lb) of waste per day, making it a practical and efficient solution for cruise ships. The machines can handle a wide variety of food waste, including meat and dairy products, making it a versatile solution for onboard food waste management.

What do they do with waste on a cruise ship?

The Resource Conservation and Recovery Act (RCRA) is the primary federal law that governs hazardous waste management. The owner or operator of a cruise ship may be a generator and/or a transporter of hazardous waste, and thus subject to RCRA rules. Issues that the cruise ship industry may face relating to RCRA include ensuring that hazardous waste is identified at the point at which it is considered generated; ensuring that parties are properly identified as generators, storers, treaters, or disposers; and determining the applicability of RCRA requirements to each. Hazardous waste generated onboard cruise ships are stored onboard until the wastes can be offloaded for recycling or disposal in accordance with RCRA.(citation needed)

A range of activities on board cruise ships generate hazardous wastes and toxic substances that would ordinarily be presumed to be subject to RCRA. Cruise ships are potentially subject to RCRA requirements to the extent that chemicals used for operations such as ship maintenance and passenger services result in the generation of hazardous wastes. However, it is not entirely clear what regulations apply to the management and disposal of these wastes.(citation needed) RCRA rules that cover small-quantity generators (those that generate more than 100 kilograms but less than 1,000 kilograms of hazardous waste per month) are less stringent than those for large-quantity generators (generating more than 1,000 kilograms per month), and it is unclear whether cruise ships are classified as large or small generators of hazardous waste. Moreover, some cruise companies argue that they generate less than 100 kilograms per month and therefore should be classified in a third category, as “conditionally exempt small-quantity generators,” a categorization that allows for less rigorous requirements for notification, recordkeeping, and the like.(citation needed)

In addition to RCRA, hazardous waste discharges from cruise ships are subject to Section 311 of the Clean Water Act, which prohibits the discharge of hazardous substances in harmful quantities into or upon the navigable waters of the United States, adjoining shorelines, or into or upon the waters of the contiguous zone.(citation needed)

Section 311 of the Clean Water Act, as amended by the Oil Pollution Act of 1990, applies to cruise ships and prohibits discharge of oil or hazardous substances in harmful quantities into or upon U.S. navigable waters, or into or upon the waters of the contiguous zone, or which may affect natural resources in the U.S. EEZ (extending 200 miles (320km) offshore). Coast Guard regulations prohibit discharge of oil within 12 miles (19km) from shore, unless passed through a 15-ppm oil water separator, and unless the discharge does not cause a visible sheen. Beyond 12 miles (19km), oil or oily mixtures can be discharged while a vessel is proceeding en route and if the oil content without dilution is less than 100 ppm. Vessels are required to maintain an Oil Record Book to record disposal of oily residues and discharges overboard or disposal of bilge water.(citation needed)
