How cool is this?! Featured on Inhabitat and blogged at Apartment Therapy, these Hieneken beer bottles were designed to turn waste into something useful.
Mr. Heineken’s idea came after a visit to the Caribbean where he saw two problems: beaches littered with bottles and a lack of affordable building materials. The WOBO became his vision to solve both the recycling and housing challenges that he had witnessed on the islands.
This concept was later termed upcycling by William McDonough and Michael Braungart's book Cradle to Cradle. (I actually came across this book in Alaska a couple years ago and bought and read it. It's really intriguing - I highly recommend reading it if you're interested in sustainable design).
