Wärtsilä has developed a complete offering for handling dry waste in cruise ships, providing a total waste management offering.

Waste treatment is an important part of Wärtsilä's environmental strategy, the new total offering has been ordered for one new vessel to be built by the Meyer Werft shipyard for British cruise operator Saga Cruises.

The order for the Wärtsilä equipment was placed in September, with an option for a second vessel.

Kevin Robertson, general manager of water systems at Wärtsilä Marine Solutions, said: “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.”

The overall 'full treatment' solution will provide the vessels with an environmentally clean, safe, and energy efficient means of handling their effluent and garbage.

Wärtsilä equipment utilises new membrane technology that is particularly energy efficient, with energy savings of up to 50% over conventional membrane systems.

Bernd Wiltfang of Meyer Werft, added: "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.”

Each vessel will be fitted with Wärtsilä's Advanced Wastewater Treatment system, including grease traps, buffer tanks, and membrane bioreactors.

A Wärtsilä Dry Waste Disposal system, including densifiers, glass crushers, bale compactors and storage as well as a Wärtsilä's Food Waste Vacuum system, Bio-Sludge Treatment system and Dry Garbage system.

When completed, the 236m-long vessels will offer capacity of 999 passengers and will sail in some of the most environmentally protected sea areas.
