In a special visit from the World News Center (yes, a “very special” episode), Bill McCormick and I discussed how resin made from fast food grease trap renderings is now being used for 3-D printers at a fraction of the normal cost, with practical medical uses already underway.  Could a house be built out of french fry grease bricks?  Possibly.  Could your new car be old chicken nuggets?  Perhaps.  Can something previously known as a Filet-o-Fish be an important element in saving humanity?  You never know.
