Want an earth friendly way to upcycle old manga or maybe even telephone books! How about using them to grow radish or other sprouts, like this project by Japanese artist Koshi Kawachi. It would make in interesting conversation piece. My only concern would be that the book might get moldy after a few days, but perhaps you could transplant them into a pot or garden.
