McDonald's Corp. is testing a more environmentally friendly alternative for its polystyrene foam beverage cups.
The restaurant chain told the environmental advocacy group As You Sow that it is taking a step toward a possible phase-out of the cups. In a test, the Oak Brook, Ill.-based McDonald's is replacing them with a double-walled fiber hot cup. It is being tested in about 2,000 of its restaurants, primarily on the West Coast.
