America’s highest-grossing fast-food chain will soon be eliminating one of the staples of to-go food packaging: foam plastic. The company recently announced it will eliminate foam packaging, currently 2 percent of its packaging by weight, by the end of 2018.
Expanded polystyrene (EPS), often known by the brand name Styrofoam, is commonly used in food packaging because it’s lightweight, cheap to manufacture and good at temperature control (both hot and cold). But it’s come under fire in environmental circles because EPS is a frequent source of marine debris and has a very limited recycling market, especially compared to paper and other plastics.
