While Hawkeye fans were watching the football game Saturday at Kinnick Stadium, Diane Roethler was keeping an eye on what people were throwing away. Items such as chips and candy bar wrappers and zip-lock bags all got rescued from the garbage to be brought to Francis Marion Intermediate School in Marion, where she teaches fifth grade. The items will be sent to a company called TerraCycle, which pays the school 2 cents plus all shipping costs for every bit of garbage it can save from being put into a landfill.
