Reduce waste, cost, and carbon dioxide with the Power Knot liquid food composter (LFC). This environmentally friendly food waste digester machine is a cost-effective and responsible way to dispose of food waste. The LFC is a commercial biodigester that takes discarded food and transforms it into gray water that is safe to send into the water treatment facilities. This ingenious food waste digester machine uses a series of processes that include microorganisms to break down food and transform it into liquid. By using a food scrap digester, you are reducing the amount of space and energy needed to remove the unwanted food scraps from your facility. It doesn’t need collecting, transporting, or piling up in a landfill. You may not be able to stop people from discarding food, but you can prevent it from piling up in a landfill.
