Leftover food from homes in west London is being used to generate environmentally-friendly electricity.
Every month thousands of tonnes of food waste from Ealing is sent to an anaerobic digestion plant in Beds.
The waste is turned into organic fertiliser and "green" energy - some of which is used to operate the plant and the rest is sent to the National Grid.
Ealing council's Keith Townsend said the move was part of its commitment to tackling climate change.
The initiative follows the success of a six-month pilot project last year.
Mr Townsend said: "Recycling rates have soared across the borough over recent months and it's a great achievement for Ealing... to be recycling all of its food waste in the most environmentally efficient way possible."
