The chief executive of bus firm Stagecoach believes fats, oils and grease dumped in the capital's sewers could power 2012 transport.

Brian Souter, speaking at the launch of 'The Oil Crunch: A wake up call for the UK Economy' made the point that the country was missing an opportunity for getting power from waste cooking oil.

Mr Souter, a Scot, said his home country had a plentiful supply of chip fat oil and he was working on using this on his buses.



He said: "We're looking at a project with all this stuff that goes down the drains builds up in the pipes and turns to a thick paste like concrete.

"We have a suggestion ... they scoop this stuff out of the sewer and it would make a really good biofuel.

"And if we had a plant in London we could run a large percentage of the Olympic bus fleet, about 3000 buses, on the gunge that comes out of our sewers."
