This environmentally friendly food waste digester machine is a cost-effective and responsible way to dispose of food waste. The LFC biodigester takes discarded food in a commercial environment and transforms it into grey water that is safe to send to water treatment facilities. The food waste digester machine uses a series of processes that include microorganisms to break down food and transform it into liquid. There are no remaining solids to be emptied from the machine. The LFC biodigester is currently on the seventh generation build.
