The new, odd-shaped lightbulbs so popular nowdays are probably going to be the only lightbulbs around in a cpl yrs, according to legislation that has been introduced. An article was posted here the other day about how they can potentially cause migraines.
At any rate, many people have told me that they cannot be thrown away in the regular garbage, so I emailed our city recycling dept and this is the response I got:
Thank you for your interest in recycling. According to the manufacturers of these items, the amount of mercury found in the newer Compact Fluorescent bulbs is a fraction of what it was five years ago. So these can be disposed of in the regular trash.
Not every city will agree, so you may want to contact your own.
