Despite your tries to abolish paper in your office complely, you probably still have some printed documents. Well one way to make sure that you don’t have unneccesary documents is by throwing away all duplicates. If you thought you lost something and printed out a second one, throw away the first on if you find it. This way you don’t have two sheets of the same thing, which reduce the amount of file storage that you need. So if you have two of something and don’t need the second, throw it away.
