Paula at Treehugger wrote about this cool chair made from recycled printing industry cardboard tubes. From the site:

Chilean design studio Onceneto teamed up with La Tercera newspaper and has been doing an interesting job recovering waste material from the paper’s print process. The first is produced with cardboard tubes from the newspaper printer paper rolls, connected with a steel support. The second were made with rubber that acts as ink transmitter in the print process, a hard to recycle material that before the design studio intervention went to waste.
