Power Knot - Liquid Food Composter (LFC)
The LFC from Power Knot is a fully enclosed automatic composting machine that disposes of any food matter within 24 hours. Once it is installed, you can add waste food at any time and only composted food is discharged into the waste water. Water is injected into the machine to maintain equilibrium for the microorganisms to rapidly decompose the food and to flush composted material out of the machine. A rotating arm inside the machine slowly churns the waste food to constantly mix the old food, new food, and microorganisms to enhance the decomposing function. The machine can be thought of as a bio-digester in which the microorganisms are digesting the organic material.
The LFC uses a series of processes in which microorganisms break down biodegradable material in the presence of oxygen. The environment of the LFC accelerates the digestion of most food products and bio plastics within 24 hours. This acceleration of the natural decomposition process of food waste is achieved with our patented mixture of microbes and enzymes and a computer control that optimizes the aeration, moisture, and temperature within the LFC. The output is grey water that is environmentally safe. You can discharge this down the drain or possibly use it to enrich your landscape.
The LFC is a practical alternative to traditional waste disposal. Anything you can eat, including fruit, 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 merely pulverized but is 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.

Saving the Planet
When waste food is discarded in a landfill, it degrades as an anaerobic process (in the absence of oxygen). This decomposition produces methane (CH4) which is 72 times worse for the atmosphere in the short term than carbon dioxide (CO2). The effect of this on global warming is huge, because the largest part of garbage sent to landfills in the US is waste food. Further, the decomposition smells and can cause health problems. Discarding 100 kg (220 lb) of waste food per day causes the equivalent of 153 tonne of CO2 per year to be sent to the atmosphere.
The decomposition inside the LFC is an aerobic process (in the presence of oxygen). This produces CO2 and water in a natural manner that is accelerated in the machine. This natural process is carbon neutral because the carbon was taken from the atmosphere to produce the food in the first place. The LFC uses minimal electricity that causes (for the LFC-100) the production of about 1.2 tonne of CO2 per year.
The LFC can be installed inside the area where the food is prepared or it can be placed outside under a suitable protective cover. The machine has castors so it can be rolled into position and then locked in place. The machine requires hot and cold water input and a 2' (50 mm) drain out. It also requires an electrical supply.
The amount of food that can be decomposed depends on the type of food, the frequency with which it is added to the machine, and the duration of the working day. The rated capacity of a machine is based on a mixture of raw and cooked food as may be found in a typical restaurant added over a 12 hour to 16 hour working day. The upper capacities in the table above assume that you add waste food over a 24 hour day. Cooked rice, pasta, or bread are some of the foods that are rapidly decomposed and if added in equal portions throughout the day then the capacity can be twice that listed in the table above.
Power Knot sells and supports its products worldwide. The LFC is available with different supply voltages so it can be used to save money globally.
