That’s right! Most shredders will shred 15 sheets of paper about 100 times a day. A box of paper holds about 5000 sheets. If you have one box of paper it will take 4 to 5 days to get it all shredded. If you buy a commercial, continuous shred machine, it will still probably only take 15 sheets at a time and you’ll be out anywhere from $2000 to $5000. It could take an employee up to 8 hours to shred 4 boxes of paper in a month. Even at only $10 an hour (and is that the employee you want to trust with confidential information?), that’s $80 in cost. Monthly service will cost you less.
