Innovative Food Waste Biodigesters For Sun Princess

Sun Princess

Power Knot Ocean  announced today the successful deployment of 26 of its machines aboard the new Sun Princess.

According to a statement, the integration of Power Knot’s LFC biodigesters and WEP effluent pumps onboard Sun Princess marks a significant stride toward sustainable waste management practices within the cruise industry.

The LFC biodigester is a food waste biodigester that uses natural aerobic digestion to break down food waste into water, mitigating the need for traditional disposal methods and contributing to a substantial reduction in both cost and environmental impact. The biodigester units are strategically placed in key areas of the ship such as a galley or garbage room where food waste is processed or handled to improve operations. With nine different sizes available, accommodating the digestion of 10 kg (20 lb) to 6000 kg (13,200 lb) of food waste per day, the LFC biodigester provides a versatile and effective approach to waste reduction.

Alongside each LFC biodigester is a WEP effluent pump. These are used to move the effluent to a convenient location so that it can easily be sent to the ship’s on board treatment facility.

“The installation of our LFC biodigesters and WEP effluent pumps on the Sun Princess exemplifies our dedication to sustainable waste management solutions. By seamlessly integrating our advanced technology into the ship’s operations, we are contributing to a cleaner, greener future for the cruise industry,” said Iain Milnes, president of Power Knot.
