Wärtsilä has recently developed a complete offering for handling dry waste in cruise ships, according to a press release.

This new offering complements the company’s extensive portfolio for handling wet waste, thus providing a total waste management offering. 

The new total offering for both black and grey water waste, as well as disposing of dry and food waste has been ordered for Saga’s new ship on order at Meyer Werft. 

The overall full treatment solution will provide the vessels with an environmentally clean, safe, and energy efficient means of handling their effluent and garbage. The Wärtsilä equipment utilises new membrane technology that is particularly energy efficient, with energy savings of up to 50 percent over conventional membrane systems.

“Wärtsilä offers a complete range of environmental solutions that meet both current and anticipated maritime regulations. Our waste treatment systems are state-of-the-art in terms of both technology and energy efficiency. Saga Cruises and Meyer Werft are both important customers, and we have tailored the solution for these ships to meet their specific needs and requests,” said Kevin Robertson, General Manager, Water Systems Wärtsilä Marine Solutions.

“We have a good relationship with Wärtsilä and are very familiar with the high quality of their solutions and the excellent level of support we can expect from them. Having a single supplier for the complete handling of all waste, both wet and dry, means fewer interface challenges which adds value to the project,” said Bernd Wiltfang, Meyer Werft.

The vessel  will be fitted with Wärtsilä’s Advanced Wastewater Treatment system, including grease traps, buffer tanks, and membrane bioreactors; Wärtsilä’s Dry Waste Disposal system, including densifiers, glass crushers, bale compactors and storage; Wärtsilä’s Food Waste Vacuum system, including feeding stations, shredders, collection tanks, vacuum stations, decanters with flocculation, and food waste chutes; Wärtsilä’s Bio-Sludge Treatment system, including a de-watered bio waste silo, decanters with flocculation, a dryer, and a dried bio-sludge silo; and Wärtsilä’s Dry Garbage system, including shredders, a dry waste silo, and incinerator.
