If you tend to sip beverages from disposable plastic, Styrofoam, or paper cups at the office, consider drinking from a washable glass or ceramic mug instead. You'll save the material and energy resources used to make the cups and reduce waste sent to the landfill.
For the average office worker who goes through one disposable cup per working day, a year of reusing a glass or ceramic mug would reduce office waste by more nearly 9 pounds, and save the company more than $20 on break-room supplies.
If 20 percent of all U.S. office workers drank from a reusable glass or mug, offices around the country could save more than $325 million on disposable beverage containers, and prevent the creation of more than 140 million pounds of garbage-enough to fill a 71 story office building.
