In March this year Starbucks announced the Betacup Challenge, seeking ideas to eliminate paper cup consumption through the design of a more convenient alternative to the reusable coffee mug.

A day or two ago the brand resumed results: more than 430 submissions were obtained, ranging from design to consumers’ motivation ideas.

The best one the jury named the collective work by Mira Holley, Nick Partridge, Gillian Langor, Mira Lynn, Zarla Ludin, Ruth Prentice. It is named the Karma Cup and used the concept of a shared reward (pic.).
