Dunkin' Donuts thinkin' outside the foam

In Massachusetts, the Patriot Ledger reports that Dunkin’ Donuts is looking to find an environmentally friendly cup to replace their current foam coffee cups.  To date, Dunkin’ has not found the cup they are looking for, that will both keep the coffee hot, and customers hands comfortable.  After four years searching, the company is reportedly looking at experiment bioresins that have yet to become commercially available.
