For ten weeks, Carnegie Mellon participated in a nationwide competition, Recyclemania, to recycle the most recyclables. Recyclemania is a competitive but friendly program that encourages colleges in the U.S. to be more conscious of their waste – making sure to recycle as possible and reduce the amount of trash that is thrown out. The program has attracted many schools to participate since its inception in 2001. This year, Recyclemania drew in 201 schools. This is Carnegie Mellon's fourth year participating.
