If you need a reason to justify eating those luscious McDonald's French fries, how about this -- within 12 months, the fleet of trucks serving United Kingdom McDonald's (NYSE: MCD) will be fueled by the oil from their deep-fryers. The chain's 155 trucks would normally burn over 1.5 million gallons of diesel fuel. Replacing this fuel will be a blend of 85% used restaurant oil, from the nation's 1,500 stores, supplemented with 15% rapeseed oil.
UK McDonald's uses a rapeseed/sunflower oil blend, free of hydrogenated fat, in its cooking. By using this oil as a fuel after its cooking life is over, the company estimates it will save 1,675 tons of carbon annually.
A McDonald's spokesperson stated that these vehicles will not emit exhaust with the aroma of French fries.
