How Is Neon Recycled?
Certain types of light bulbs contain mercury vapor (a toxic metal) and require special handling with regard to disposal and recycling. They include bulbs such as fluorescent, compact fluorescent, high intensity, high pressure sodium, mercury vapor and neon bulbs used for commercial signage.-
Regulations
-
The Environmental Protection Agency (EPA) regulates the disposal of mercury containing bulbs as hazardous waste.
Concerns
-
Although this type of light bulb contains very small amounts of mercury, the concern is that disposal in landfills can result in the release of mercury into the air or groundwater. This can lead to contamination of the food chain according to the EPA.
Disposal
-
The EPA encourages the recycling of this type of bulb. Most cities and states have specific programs and guidelines for the disposal (recycling) of hazardous wastes with regard to pick up or drop off of such materials.
Process
-
Lamp Environmental Industries indicates that the process for recycling mercury involves physical separation of the content of the bulbs. The mercury is then distilled for reuse.
Considerations
-
The Wisconsin Department of Natural Resources indicates that there is no mercury in red neon lights. However, they do contain a mixture of gases and should be recycled with other neon light bulbs. Caution should be exercised when handling these types of bulbs to prevent breakage.
