Dunkin’ trials bioplastic straws, America runs greener


In Massachusetts, Dunkin’ has said it is testing the use of bioplastic straws at 250 locations throughout the United States.

Formerly known as Dunkin’ Donuts, the popular coffee chain says the straws are made of PHA, a bioplastic produced via fermentation from canola oil.

“[W]hile the straws have the same look and feel as traditional plastic, the PHA material is both marine and soil biodegradable, as well as home and industrial compostable, creating significant environmental advantages over plastic,” Dunkin’ says in a statement on their website. “These straws are certified by TUV Austria, the premier independent, certifying body of the European Union recognized for its rigorous standards for biodegradable products. The straws are also certified for industrial compostability by the Biodegradable Products Institute (BPI), which is a globally recognized certification, education, and advocacy organization that supports a shift to the circular economy.”

The company recently replaced foam cups with paper at all its global stores, and has committed to switching from plastic to wooden stir sticks at all its US restaurants by the middle of next year.

“Dunkin’ will continue to evaluate and test all available alternatives until we believe we have found the optimal solution based on performance, environmental impacts, quality, commercial viability, and cost,” the company adds.
