In a 2010 report, Dunkin’ Donuts said it considered its use of foam to be “the most prominent sustainability issue we must deal with.”
In a follow-up report two years later, the company said it was still searching for an alternative to foam.
Six years after declaring that replacing foam cups was the company’s “#1 sustainability priority,” a majority of Dunkin’ Donuts restaurants still serve coffee in cups made of polystyrene, one of the most environmentally unfriendly materials. Because of this many municipalities across the country are banning it.
In those places the company has introduced cups made of a recyclable plastic called polypropylene.
“We are not prepared to transition fully out of foam at this time,” said Christine Riley Miller, Dunkin’ Brands’ senior director of corporate social responsibility.
Other companies, such as McDonald’s were able to make the switch from foam to paper cups and Starbucks’ hot cups are made with 10% recycled paper fibre .
