Now McDonald's wants to go green as well. The American fast food chain announced that the cooking oil used to fry their food in their 1200 outlets across the United Kingdom will be recycled into fuel for its fleet of lorries.McDonald's has already switched its fleet in Austria to biodiesel derived from its cooking oil, claims the move will cut its carbon emissions by 75 per cent in this country, the equivalent of taking 2,400 cars off the road. If the cut is that high remains to be seen.

This is the latest attempt by the fast-food giant to tackle its image, which has been hit by claims that it contributes to problems ranging from obesity to intensive farming. Its 155-strong fleet of lorries will be converted to biodiesel by the end of this year and will use 85pc used cooking oil, collected from the restaurants and filtered to remove traces of food. It will then be cut with 15 per cent pure rapeseed oil.

It is not clear at the moment if the costs for generating the fuel from the used oil is economy wise a smart step. Critics say it would help more if people simply would walk to get their burger.
