The secret behind a CFL’s energy efficiency is a trace amount of mercury sealed within the bulb’s glass tubing. Most bulbs only contain an average of 5 milligrams of mercury – equivalent in size to the tip of a ballpoint pen. But proper disposal is still essential.
Rather than toss them into the trash, check out safer disposal alternatives by contracting your local waste management agency or visiting earth911.org or contact SBU for our recycling schedule.
If you must throw away a bulb, carefully wrap it in a sealed plastic bag first and make sure it won’t be incinerated.
