How Food Waste Impacts the Ocean – Leading cruise lines including Disney Cruise have chosen to use Power Knot biodigesters as a result of its solid construction, simple operation, and advanced analytics.

Our Products

The LFC® biodigester is a commercial aerobic biodigester that decomposes food wastes within 24 hours. It uses a series of processes in which micro­organisms break down biodegradable material in the presence of oxygen. The output is grey water that can be pumped directly overboard or treated by the vessel sewage treatment plant.

Power Knot Ocean’s mission is to provide hassle-free solutions for onboard food waste. We have years of experience in the marine market, and with rapid growth in this area over the last 18 months, we are truly fortunate to be able to help vessels achieve their sustainability goals, and provide clear analytics to document this. We are also proud that our machines eliminate accidental plastic in the food waste stream from entering the ocean.
