Starbucks rolls out re-usable cup option nationwide in move to cut down on waste

Starbucks is rolling out a greener beverage option, but it won't come in the company's classic green-and-white cups. 

Starting Wednesday, drive-thru customers and those who place orders through the coffee chain's mobile app can bring their own cups, an effort to cut down on waste, the company said Wednesday. The only requirement is that cups must be clean. 

"Offering customers more options to use a personal cup when they visit Starbucks marks tangible progress towards the future," Starbucks Chief Sustainability Officer Michael Kobori said in a statement.
