In honor of National Recycling Day, Office Depot has compiled this top-ten list of ways to recycle at the office.

1. Buy recycled paper and print on both sides. When using paper in the office, print on both sides of the sheet and recycle the paper when you are finished. Today, only half of the paper used in North America is recycled. By recycling one ton of paper, you can save 17 trees, almost 7,000 gallons of water and more than three cubic yards of landfill space.


2. Recycle your outdated technology. According to the U.S. EPA, Americans throw out two million tons of e-waste each year. Avoid adding to that waste by recycling your old technology.


3. Make recycling bins readily available. Make sure your home and office are outfitted with recycling bins for paper, plastic and metal. Keep them out in the open and label them appropriately. Sometimes the convenience factor is all that is needed.


4. Recycle your empty ink and toner cartridges. Almost eight cartridges are thrown out in the U.S. every second of every day. That's almost 700,000 cartridges per day.


5. Buy remanufactured ink and toner cartridges. Each remanufactured cartridge keeps approximately 2.5 lbs. of metal and plastic out of landfills and saves about a half gallon of oil.


6. Recycle old newspapers lying around the office. When finished reading the newspaper, either leave it for someone else to read or recycle it! It can take decades for newspapers to biodegrade when sent to landfills.


7. Look for the recycled option in all the products you buy. It's not just paper that's recycled anymore!


8. Buy rechargeable batteries. It takes 1,000 regular batteries to equal the lifespan of one rechargeable battery. When discarding your current batteries, recycle them.


9. Purchase rewritable CDs and DVDs so that you can reuse them from project to project. Instead of printing out a lengthy document, save it to a flash drive.


10. Reuse your morning coffee cup. Or better yet, buy a mug to avoid the waste caused by throwing away the paper or Styrofoam. According to the U.S. Department of Energy, it takes a million years for Styrofoam to biodegrade.
