Styrafoam

I don't to step on that other dude who writes articles on this site about the environment, but, I feel like I have to.  I have noticed for years that the exhibit floor at a trade show seems to be a terribly wasteful place.  When the truck is loaded up at the end of a show and I look across the floor, I can not believe the mess that is left.  It is almost post apocalyptic.  Unread literature, trashed exhibits, spent tape, bubble wrap and where did all those little Styrofoam chips come from?  Not withstanding the cost to the environment from shipping exhibits that sometimes weigh more than a house from place to place.  What can be done?
