About the LFC biodigester for ships

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.

Using Power Knot’s LFC biodigesters on ships ensures that organic waste can be safely disposed of with no possibility of plastics entering the ocean. With hundreds of machines deployed across cruise ships, cargo ships, FSRUs, tankers, and mega yachts, Power Knot Ocean brings seven years of experience to solving problems of organic waste on vessels while meeting MARPOL regulations.

How it Works

The LFC® biodigester uses a series of processes in which microorganisms break down biodegradable material in the presence of oxygen.

Organic Waste

Organic waste is segregated from other types of waste and placed into the LFC biodigester.

Microorganisms

A special blend of microorganisms from Powerzymes are housed in Powerchips.

Oxygen

Paddles in the LFC biodigester turn to add oxygen and begin aerobic digestion.

Digestion

Microorganisms eat the food waste and convert it into water.

Output

Discharged into waste stream.

Prevent Plastic Pollution with the LFC biodigester

The mechanical design of the biodigesters ensures that organic waste can be safely disposed of with no possibility of plastics entering the ocean.

If any non-organic material ends up in the biodigester, it is not digested by the microorganisms. Multiple levels of protection such as metal grates and filters prevent the plastics from contaminating the waste stream. The plastics remain safely in the machine until removed by the operator.

The result output is grey water free from contaminated microplastics that can be pumped directly overboard or treated by the vessel sewage treatment plant.
