McDonald?s to power trucks with its own used cooking oil.

The oils that sizzle McDonald?s fries and chicken nuggets will soon also stoke its trucks, as the fast food chain starts converting its cooking oil into biodiesel. McDonald?s plans to run its 155 UK delivery trucks on biodiesel made entirely from cooking oil collected from its restaurants by the end of the year. The fast-food group, which to date has been running trucks on 95 per cent diesel and 5 per cent biodiesel, will initially use a blend of 85 per cent biodiesel and 15 per cent rapeseed oil.
