Mackie diesel

[Plex]

Back when we were being all green last month, we brought you news from the US fast food chain Burgerville, which was creating thousands of gallons of lovely biodiesel - from its discarded cooking oil.

'Twas a plan we approved of heartily, and now you don't even need to travel Stateside to enjoy the distinctive smell of double cheeseburger 'n' fries as a delivery truck thunders past.

Because McDonalds has today announced that it is to convert all of its UK delivery vans to run on cooking oil-based biodiesel.

Once the oil has been used to bubble your Freedom Fries to a tasty state of crispiness, it'll be combined with rapeseed oil to power McDonald's 155 lorries, saving some 1,650 tonnes of carbon each year.

All very impressive, but what's happened to the to-hell-with-ya, free-livin' McDonalds of old? Next thing they'll be offering salads with your Big Mac.
