When you flush the toilet on a cruise ship, you may be surprised to learn that your waste isn’t being sent straight to the ocean. Cruise ships have complex systems in place to deal with wastewater and solid waste. In this article, we’ll explore what happens when you flush the toilet on a cruise ship and how they manage such large amounts of waste.
Treated Wastewater
The wastewater produced by sinks, showers, and toilets is collected in tanks located below the vessel. The water is then passed through a treatment system.
This system removes solids, oils, and other contaminants before the wastewater is passed into the ocean. The water is usually treated to a level that meets or exceeds local standards.
Solid Waste Management
Solid waste produced onboard a cruise ship is managed in two ways: onshore disposal and onboard processing. Onshore disposal involves transporting the solid waste from the cruise ship to an approved facility on land where it can be processed or disposed of safely. Onboard processing involves sorting and packaging solid waste for disposal at sea.
Food Waste
Food waste from cruise ships can be recycled rather than going directly into landfills or oceans. Cruise lines partner with companies that turn food scraps into compost which is then used to nourish crops or gardens.
Conclusion
When you flush the toilet on a cruise ship, your wastewater is collected in tanks below deck before being treated and discharged safely into the ocean according to local standards. Solid waste management on a cruise ship involves both onshore disposal and onboard processing while food scraps are recycled into compost for gardens and crops.
