Power Knot installs food waste system at airport catering facility

Power Knot LLC, headquartered in Fremont, California, has announced the successful installation of a fully integrated food waste processing facility at an airport catering facility.

The catering facility is one of the world’s largest catering operations, Power Knot says, and serves hundreds of thousands of meals daily. The company did not specify the name of the airport.

To address the challenge posed by organic waste generation, Power Knot deployed a system that includes its SBT-140 bin tipper, BCG-315 grinder, FSC-500 screw conveyor and an LFC-2000 biodigester.

At the center of the installation is the high-capacity LFC-2000 biodigester, capable of digesting thousands of kilograms (kg) of food waste per day. The SBT-140 bin tipper tips food waste into the BCG-315 grinder, which then chops up the organic material. The material is sent 5 meters (16.4 feet) through the FSC-500 to the digester.

Since its installation in December, the catering customer typically deposits 80 bin loads a day, and the machine is digesting an average of 3,000 kg (6613.87 pounds) per day.

“This project highlights Power Knot’s ability to deliver integrated solutions for major food service operations,” Iain Milnes, president of Power Knot, says. “With our technologies, catering facilities can process food waste more sustainably while at the same time reducing costs and improving operations.”
