"Cooking waste from thousands of London restaurants and food companies is to help run what is claimed to be the world's biggest fat-fuelled power station.

"The energy generated from the grease, oil and fat that clogs the capital's sewers will also be channelled to help run a major sewage works and a desalination plant, as well as supplying the National Grid, under plans announced by Thames Water and utility company 2OC."
