The Betacup Challenge—now entering its second half—is asking designers to invent a more earth-friendly solution to the current non-recyclable coffee cup. With sponsorship from Core77 and Starbucks, The Betacup project is offering $20,000 to the person who can best channel their inner treehugger and do their part to save the planet.
So far there has been about 200 ideas accounted for, and a few clear favorites have garnered some attention. Core77 believes that the Une Coffee Cup, submitted by Tom Fereday, is one of the most convincing.
