ONBOARD

ARE YOU LOOKING FOR AN

FOOD WASTE SOLUTION?

Introducing the 

LFC BIO-DIGESTER

Marpol Annex V gives clear instruction on permissible and prohibited disposal of food waste, and the need for a garbage management plan. Yachts have to store, freeze, tender ashore and find suitable refuge collection points for their food waste.​

Having a Bio-Digester onboard eliminates all of these inconveniences.

The LFC20 unit is smaller than a dishwasher and can be easily installed onboard your vessel.

How a yacht benefits from a food waste bio-digester

ADD FOOD

The LFC is a fully enclosed automatic composting machine that disposes of food matter within 24 hours. Once it is installed, you can add waste food at any time and the output is grey water that is environmentally safe and has a low BOD5 value.

FOOD IS DIGESTED

Water is injected into the machine to maintain equilibrium for the microorganisms to rapidly decompose the food and to flush decomposed effluent out of the machine. A rotating arm inside the machine slowly churns the waste food to constantly mix the old food, new food, oxygen, and micro-organisms to enhance decomposition.

RELEASED AS 'GREY WATER'  

The waste water is drained into the grey water system and can be pumped directly overboard or treated by the vessel sewage treatment plant. Due to the aerobic digestion process the BOD5 values in the effluent do not cause additional loading on the Sewage Treatment System. With a 0.9mm filter we can also say there is zero plastic waste passing through the Biodigester onto the ocean.

HOW IT WORKS

The LFC uses a series of processes in which microorganisms break down biodegradable material in the presence of oxygen. The environment of the LFC, with our proprietary mixture of microbes and enzymes, accelerates the digestion of most food products within 24 hours. The output is grey water that is environmentally safe. You can discharge this overboard safely.


The LFC is a practical alternative to the traditional disposal of waste food. Anything you can eat, including fruits, vegetables, meat, fish, cheese, bread, rice, and noodles can go into the LFC. The machine can compost both raw and cooked foods. The process is totally green because it uses no chemicals.


As one of Earth's oldest processes, composting is the most effective means of stabilizing and converting biodegradable waste. The waste food is not being chopped but it is decomposed to such a degree that it becomes a liquid and can exit the machine only through a fine mesh screen. The rich by-product is therefore safe and replenishes nature.
