Operating principle

What is a Bio-Digester?

The LFC is a fully enclosed automatic composting machine that disposes most food matter within 24 hours, before safely releasing it to the sewage system. And by diverting your waste food from landfills the LFC helps you significantly reduce your carbon footprint.

The LFC uses a series of processes in which microorganisms break down biodegradable material in the presence of oxygen.

  • Cafes and restaurants
  • Hospitals and aged care homes
  • Corporate and university cafeterias
  • Convention centers
  • Supermarkets and food distribution centers
  • Military, police & jails
  • Island communities and resorts

CO₂ reduction

The LFC leaves a positive CO₂ footprint.

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; for example, production of the electricity used by an LFC-100 causes about 2.1 tons of CO₂ per year.

Did you know?
The LFC-100 saves 153 tons of CO₂ per year, compared to discarding your food waste on a landfill.

Service and support

  • Three year warranty
  • World wide sales, service, and support

Connection to the Cloud

The LFC can connect through its Ethernet port to a cloud server maintained by Power Knot. The LFC securely sends data about the operation of the LFC to the server and that data is retained for five years. The data includes the amount of waste food digested hourly, daily, weekly, monthly, and yearly; the number of times the door is opened in these periods; and the amount of CO₂ diverted from the landfill during these periods. If you have multiple machines, you can aggregate the data into a single report.
