There are certain tactile sensations that consumers associate with fast-service franchises. Go into a McDonald’s and you’re likely to walk out with a French fry container soaked in grease. Head to Taco Bell and your takeout bag will be heavy with hot sauce packets. At Dunkin’ Donuts, a thick-walled foam cup keeps your hand cool while your coffee stays hot.

Not for much longer. This week, Dunkin’ announced plans to insulate their beverages in a more environmentally friendly way. Beginning this spring, the company will eliminate the polystyrene foam containers they currently use in favor of a new, double-walled paper cup, a move that's expected to remove 1 billion foam cups from waste streams annually.

The paperboard used in the cups—which will come in the chain’s standard four sizes, from small to extra large—is certified to the Sustainable Forestry Initiative Standard and is said to have heat retention properties equivalent to the current foam cup. Dunkin’ is promising that consumers won’t need a cardboard sleeve to insulate themselves against the heat.

“With more than 9000 Dunkin’ Donuts restaurants in the U.S. alone, our decision to eliminate foam cups is significant for both our brand and our industry," Karen Raskopf, Dunkin’ Donuts's chief communications and sustainability officer, said in a statement. “We have a responsibility to improve our packaging, making it better for the planet while still meeting the needs of our guests. Transitioning away from foam has been a critical goal for Dunkin’ Donuts U.S., and with the double-walled cup, we will be able to offer a replacement that meets the needs and expectations of both our customers and the communities we serve.”

The move is scheduled to begin in New York and California and spread to all Dunkin’ locations worldwide by 2020.
