Recycle Your Coffee Habit

Science may have confirmed the health benefits of your three-mug-a-day habit, but that doesn’t mean you should go back to guzzling joe out of disposable cups. The average American office worker uses about 500 of them each year, and all that paper and polystyrene adds up—in landfills. (Don’t even get us started on K-Cups.)

One solution: putting the brewed byproducts—the grounds—to work. A German company called Kaffeeform is fabricating a line of reusable cups and saucers made from old coffee grounds.
