LFC® biodigester

Automatic food waste digester

The LFC biodigester reduces the expense and mess of disposing of food waste by digesting it onsite.


The LFC® biodigester is a commercial aerobic biodigester that decomposes food waste within 24 hours. It uses a series of processes in which micro­organisms break down biodegradable material in the presence of oxygen.

Organic Waste

Organic Waste

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



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



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



Microorganisms eat the food waste and convert it into water.



Discharged into waste stream.

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.
