No waste water from our onboard showers, sinks, toilets, kitchen galleys or laundry operations leaves our ships without proper treatment and any discharges from our fleet undergo a comprehensive purification process.
In 2008, when launching our Fantasia Class of ships, we started to equip our ships with Advanced Wastewater Treatment Systems. An Advanced Waste Water Treatment System treats waste water to a very high quality by mixing different waste streams together and filtering out the larger components. What comes out on the other end then gets processed even further through very fine filtration and treatment processes, to produce effluent that is of a higher standard than most municipal waste requirements around the world.
Through our systems, hazardous substances and pollutants are filtered out and digested by bacteria. To avoid risking harm to marine life, the remaining purified wastewater is disinfected by UV processing and never chlorine. We monitor key indicators to ensure any remaining bacteria levels are favourable before discharge.
As a result of this process, the wastewater that we discharge reaches near tap water quality.
The separated solid residue is removed from the cycle. It is then dried, compacted and compressed into high-grade pellets. These pellets can act a source of fuel for specific onboard energy needs. Depending on the cruise itinerary, we may also offload this dried biomass ashore, where it can be repurposed for energy production.
Other liquid waste that may be hazardous to the environment such as cooking oil, oily water, machinery lubricants and cleaning products are never discharged into the sea, but are offloaded ashore by authorised companies.
