That's right: one Berlin-based designer decided to take all of our used-up coffee grounds and turn them into something useful. Namely, a cup to drink more coffee from. It's basically caffeine Inception.
The brainchild of Julian Lechner, these bean-based vessels are made from a proprietary blend of natural polymers, wood particles, and coffee grounds gathered from local Berlin cafes, all of which is then injection-molded to produce the glorious cup-and-saucer sets you see above. The new material, dubbed Kaffeeform, is even hearty enough to withstand being tossed in the dishwasher -- although, if you're all about sustainability, you probably don't own a dishwasher.
