McDonald’s announced it would test paper coffee cups instead of the current foam cups in 2,000 of its U.S. locations. Part of McDonald’s resurgence in recent years was because of their new McCafe drinks and improved roasted coffee. But in addition to giving coffee chains like Starbucks and Dunkin Donuts a run for their money, all those polystyrene foam cups create massive amounts of waste. In addition to the waste problem, international health organizations like the International Agency for Research on Cancer have suggested that styrene in any form could have links to cancer. And as more consumers question not only the ingredients that make up their food, but the packaging in which they are delivered, even large companies like McDonald’s are taking a hard look at how they wrap and contain their products. Calls for improved packaging are a familiar refrain for McDonald’s. In the 1980s, growing outcry about those bright polystyrene clamshell burger containers pushed McDonald’s into using paper instead. McDonald’s touts its reduce, reuse and recycle program, and now this is the opportunity for the burger giant to put its money where its mouth is. A change in business practices is important: litter from fast food companies is not only challenging municipalities with their waste diversion plans, but pollutes water supplies across the country, too.
