Wastewater treatment
Moving bed biofilm reactor (MBBR)
Ideal for large vessels. Extreme energy efficiency:
low energy and chemical consumption, low
operating costs, and minimal daily operational
requirements.
Advanced membrane bioreactor (MBR)
Compact design with excellent treatment results. No
chemicals needed in normal operations. Low power
and maintenance needs. Meets US Coast Guard
standards.
Advanced Wastewater Treatment Solutions for Ships:
IMO 227(64) compliant nutrient removing units

Waste minisation: Cruise Ship Waste Characteristics
• Extensive Shipboard study on waste
operations done recently on several cruise
ships
• Lately comprehensive waste sampling done
on 7 cruise ships; Up to 10 m3 sample size
• Sorting test for definition of recyclable
materials
• Elemental and calorific analysis per each
sorted fraction
• High variation of dry waste moisture

Waste Minimisation: Identifying separately collectable
materials by waste sorting tests

Waste Minimisation: Identifying recyclable materials
• Good knowledge on shipboard waste composition by sorting tests
• IMO waste represents well the shipboard dry waste
• Source-sorting of cardboard on cruise ships is fairly effective
• High waste reduction by paper and plastic bottle sorting on the hotel
areas of cruise ships.
• Evac will keep collecting the waste data in the future

Dry and wet waste treatment
Macerating vacuum food waste system
Easy-to-maintain system includes small piping, bringing repair and space benefits.
Cyclone Incinerator
New generation moving crate incinerator with high energy efficiency due to optimized
burning process, compact size, and highest burning capacity and cleanest flue gas on
the market. Can be combined with energy recovery system.
Waste briquetting unit
Volume reduction of non-recyclable mixed waste to one-tenth or for briquetting
recyclable material such as tin or cardboard to reduce volume of stored dry waste.
Discussion:

• Waste management in modern cruise ships are effective and flexible
• Waste material recovery can be increased onboard cruise ships and
the limitations are known.
• Common and standardized method for port reception of wastes is
needed
• Cooperation between shipowners and port operators and waste
management solution supplier (Evac)
• Adaptation of the cruise ship waste management according to
selected pathway of port operation
• The recycling ratio is limited to c. 40 %
• The onboard waste incineration is and will be needed, because of
non-recyclable multimaterial waste,
• Port mode for waste incineration – Definition of flue gas limits?
