Though many companies are already recycling their office paper, you can clean up your office by employing and encouraging some of these money-saving practices.
Copy on both sides of the paper. This is especially efficient for internal documents and drafts.
Reduce documents to fit two pages onto one. Use for circulating rough drafts or file copies of documents.
Use lighter weight paper. Lighter paper requires less energy and fewer raw materials when it's manufactured.
