Waste Not, Want Not

Changing habits to be less wasteful can be hard, but it can also save you a lot of money. Oprah should know. Harpo goes through about 1,600 paper cups a day—or 32,000 cups a month—which employees use for water, coffee and tea. Some people even double their waste by "double cupping."

All that waste adds up to serious money. Harpo spends approximately $41,000 each year on disposable paper cups!

In the spirit of this show and honoring our planet, Oprah declared April 14, 2008, "No Paper Cup Day" at Harpo. Every single paper cup was locked up. "Fortunately, there were no riots at the coffee machines," Oprah says. "I'm proud to say everybody figured it out. In fact, are you listening, Harpo? I'm making it permanent. ... Maybe you at home can do this at your company too."
