Booming sales of cold drinks at Starbucks have created a problem: growing amounts of plastic waste from the single-use cups that Frappuccinos, Refreshers, cold brews and other iced drinks are served in.

The coffee giant said Thursday it plans to alleviate some of that waste with new disposable cups that contain up to 20% less plastic. The cups are set to be rolled out to stores in the U.S. and Canada starting this month.

Amelia Landers, Starbucks’ vice president of product innovation, said the Seattle-based company spent the last four years developing the new containers. Engineers tested thousands of iterations to see how much plastic they could remove while still making the cup feel sturdy.

“We feel like it’s industry-leading,” Landers said. “It’s the best expression of a cold plastic cup.”

Starbucks says Frappuccinos and other cold drinks now account for 75% of its U.S. beverage sales, up from 37% in 2013. The company estimates the new cups will keep more than 13.5 million pounds of plastic out of landfills each year. Producing the tumblers also requires less water and creates fewer carbon emissions, a leading cause of climate change, it said.

Starbucks made other changes as part of the redesign. The new cold cups feature raised dots near the bottom, so baristas – including those with impaired vision – can quickly feel with the swipe of a thumb which size cup they’re holding. And the 12-ounce cup — that's the “tall” size in Starbucks lingo — is shorter and wider to accommodate the same-size lid as larger cups.
