Dunkin’ Donuts Tests Recyclable Cups as Foam Loses Favor

Dunkin’ Donuts, looking to phase out its signature foam cups, is testing recyclable-plastic versions to see if they can withstand temperatures of 200 degrees Fahrenheit while helping preserve the environment.

Stores recently started using polypropylene hot-coffee cups in about 100 locations in New York, Vermont, Massachusetts and California, Scott Murphy, chief supply chain officer at Dunkin’ Brands Group Inc., parent of the business, said in a telephone interview. Dunkin’ will probably make a decision on a foam cup alternative next year and begin a nationwide introduction in 2016, he said.
