Many of us use and appreciate energy-efficient CFL bulbs in our homes. They cost more than traditional light bulbs up front, don't always work well with dimmer switches, and don't always produce a warm glow, but the substantial energy savings and environmental benefits outweigh the drawbacks for a growing number of consumers. In fact, over 30% of the light bulbs sold in the US are Energy Star certified, use 75% less energy than traditional light bulbs, and allegedly last 10-25 times longer too. We are somewhat dubious about their reputed endurance, having replaced enough CFL light bulbs in the past few years to know they often flame out earlier than expected. When that happens in New York City, what should you do with them?
The answer is "whatever you want". One drawback to using CFL light bulbs is the small amount of bio-accumulative mercury in the bulbs. Because of this, the EPA recommends that they not be placed in the trash.
Although it's illegal in some states to throw away CFL light bulbs with household trash, it is not illegal to do so in New York. That said, (i) the city strongly advises its residents to recycle them through the proper channels: they can be brought to a participating retailer, or one of NYC's Household Special Waste Drop-Off Sites, and (ii) commercial users must recycle fluorescent lighting in accordance with applicable hazardous waste regulations.
Please think twice before putting them in the trash!
