Some papers are too confidential to simply toss into a wastebasket.
Old proposals, contracts, checks and other matter must be destroyed before they reach prying eyes. Shredding is a vital way to protect you company's privacy. Even as companies use more and more computers, they still need paper. Even if documents are transmitted over the Internet, they are often printed if they need to be studied or signed. That means trade secrets or important internal information may accidentally leak out.
