What bulbs can’t be thrown out in the regular trash?
Some light bulbs contain harmful chemicals and hazardous waste that cannot be thrown out in regular trash. This includes compact fluorescent light bulbs (CFLs) which use argon and mercury to generate ultraviolet light which excites fluorescent coating to emit visible light. According to the U.S. Environmental Protection Agency (EPA), CFLs only contain a small amount of mercury. This mercury is not released when the bulbs are intact, but when they break the mercury vapor is released.
Other types of bulbs can also contain mercury, so make sure to check the labels. Use the Lighting Facts Label to identify whether or not the bulb contains mercury. It will be clearly labeled as per government requirements and may use the element symbol for mercury as well (Hg).
Mercury is harmful to human health and high levels can impact the brain, heart, kidneys, lungs, and immune system. It also has negative ecological effects, impacting animals and their ability to survive, reproduce, and develop, and can lead to abnormal animal behavior.
Although there is only a small amount of mercury in these bulbs, it can add up and contributes to the concentration of mercury in the atmosphere from other sources as well. This becomes a global problem as emissions are spread across the globe through natural processes such as jet streams and through rainfall.
Where do I dispose of light bulbs?
CFLs and other bulbs containing mercury should be recycled as per local guidelines. In Deschutes County, CFLs and other fluorescent tubes are accepted at the Knott Landfill Hazardous Waste Facility. Hazardous waste at the landfill is free of charge for residential users and is open from 9 am to 3 pm on the second and fourth Friday and Saturday of each month. Make sure to check the Solid Waste Calendar to confirm!
