Government Agencies Worldwide Turn to Power Knot to Help Lower Their Carbon Footprints by Eliminating Waste Food

May 20, 2019

Government-managed kitchens and canteens set the right example by diverting waste food from landfills to reduce carbon emissions

“By installing a Power Knot biodigester in a high-volume kitchen or canteen, a government agency can both reduce carbon emissions and eliminate the costs of transporting waste food to a landfill.”


Power Knot, the market leader in products that process waste food in commercial foodservice operations, is gaining worldwide popularity with government agencies and branches of the armed services. From official administration residences to military bases and correctional facilities, Power Knot biodigesters and bin tippers are being installed in record numbers as governments implement stringent measures to reduce the pollution and carbon emissions of state-run foodservice operations.

“As governments and their agencies develop measures to support the UN Sustainable Development Goal and the Paris Agreement, sustainability managers at government-run facilities are responding by looking for ways to divert waste food from landfills or composting facilities,” said Iain Milnes, president of Power Knot. “By installing a biodigester in a high-volume kitchen or canteen, a government agency can both reduce carbon emissions and eliminate the costs of transporting waste food to a landfill.”

Dozens of Power Knot LFC biodigesters are going online at government facilities around the world

  • Canada’s Department of National Defence took delivery last month of several orders of Power Knot LFC biodigesters and SBT™ bin tippers.
  • Chile’s Palacio de la Moneda in Santiago, the seat of the President of the Republic of Chile (the equivalent of the United States’ White House), installed a Power Knot LFC biodigester in March 2019.
  • In Canberra, Australia, a Power Knot LFC biodigester will soon be eliminating waste food at Parliament House, whose kitchen caters not only to government employees but also to high-profile private events and functions.
  • Here in the USA, dozens of Power Knot LFC biodigesters have been installed in military bases and correctional facilities since 2014.

How the Power Knot LFC biodigester works
The LFC biodigester is a practical alternative to the traditional disposal of waste food. It uses a series of processes in which microorganisms break down biodegradable material in the presence of oxygen. The LFC environment accelerates the digestion of most food products within 24 hours by using a proprietary mixture of microbes and enzymes. The output is grey water that is environmentally safe, and suitable for discharge down the drain or to enrich landscapes. Almost all waste food from an industrial kitchen, including fruits, vegetables, meat, fish, cheese, bread, rice, and noodles can go into the LFC biodigester, and the machine can compost both raw and cooked foods. The process is totally green because it uses no chemicals.

Supports sustainability goals
Government agencies are especially concerned about deriving key performance indicators of all sustainability initiatives. To support environmental sustainability reporting, all Power Knot LFC units can upload detailed performance data to the LFC Cloud. Sustainability managers can then view how much waste food has been processed by any machine or site, and gain insights into the reduction of carbon emissions to support wider reporting requirements.
