Bryan Dooley, Staff Writer February 16, 2012 Reduce, reuse, Recyclemania. Recyclemania is an annual contest which lasts from February through March. Over 400 colleges and universities nationwide — including Guilford — will compete to see which one recycles the most waste. “We're submitting results of measured landfill waste,” said David Petree, director of environmental sustainability, via email. “Food waste and electronic waste. Each of these categories are measured by weight and the results are posted weekly on the Recyclemania web page.”
