Although a small country, we have an enormous livestock industry and a correspondingly huge dung mountain.” So Andreas Muller, of Droog Design, created a package for tulip bulbs is made from compressed cattle dung. “The interesting thing about this packaging is that it eats into the surplus and acts as a fertilizer at the same time.” Check out the sculpted gourds, too, on o2.org.
