Starbucks Coffee Korea has banned the use of disposable cups at all 23 stores on the southern island of Jeju starting on Tuesday.
The Starbucks outlets on Jeju Island will only serve drinks in mugs, personal cups, and multi-use cups.
The multi-use cups can be returned through 26 return slots that have been set up at all Starbucks stores on Jeju Island, including those at Jeju International Airport and an SK rent-a-car store.
Four Starbucks stores underwent a trial period without disposable cups since July, revealing a return rate of multi-use cups stood at around 50 percent.
The multi-use cups at Starbucks stores on Jeju are expected to save over 5 million disposable cups each year.
