How you dispose of compact fluorescent light bulbs is important. Why? Because they contain mercury which can be harmful to the environment. If your bulb is not broken, it's much easier. Most major cities have a recycling center that will take cfl bulbs. They then send the bulbs to a center that will take off the base to recycle, they will recycle the glass and will also salvage the mercury and reuse it as well.
If you don't have a recycling center in your area, according to the EPA you can double bag your bulbs and place in your trash. If you are a commercial operation, very different rules apply. You must get your fluorescent bulbs to a recycling center and often pay a fee to do so. You can find online service to do this if you don't know anyone locally. A big one is EPSI.
