Dunkin’ introduces the phade, a non-soggy compostable straw

A new biodegradable drinking straw, called a phade straw, is appearing in Dunkin’ stores in the U.S. Its manufacturer, WinCup, says it’s meant to be composted at home or in an industrial facility. But it also knows you might not compost it at all — and that’s OK.

“No matter if it ends up in the ocean, on the beach, in your backyard, on the side of the road, and definitely in a landfill where there’s lots of bacteria living, phade will have a great end of life story,” said WinCup CEO Brad Laporte. “It turns back into organic matter.”

In 2018, a video of a turtle with a plastic straw stuck up its nose went viral, and led to calls for straw bans across the country. Soon after, WinCup started developing a product that could address plastic pollution.

“Better straws was the solution,” Laporte said.

The new straws are made with PHA-polyhydroxyalkanoates — a material made by fermenting sugar or starch feedstock, or in this case canola oil. Dunkin’ has been trying them out in about 250 stores across the U.S. since late last summer.

In the past, there have been three categories of alternatives to traditional straws. Paper straws often use nonbiodegradable adhesives and become soggy quickly. Straws made of PLA, or polylactic acid, are made from renewable materials like corn starch or sugar cane. They’ve been used to replace traditional plastic straws in many instances, but they only compost in industrial facilities, which aren’t available everywhere. They also aren’t marine biodegradable, so if they end up in the ocean, they won’t break down. And restaurants can’t hand out a metal straw with your to-go latte.

WinCup, which makes disposable cups, bowls, containers and lids in addition to straws, spent about a year and a half working on the phade straw.
