The recycling of mercury-containing light bulbs and other types of lamps minimizes the release of mercury into the air around you, and into the environment. Lamps, fluorescent tubes and CFLs are easily broken and can end up in a trash can because most people don’t know where to recycle their lamps, or even that they should recycle them. Some of the components of a lamp can be recycled, but not all of them. The glass from a lamp is permanently contaminated and cannot be used as glass again. Sometimes, the glass can be added as a feedstock for concrete, asphalt or other building materials. If it cannot be recycled there is a beneficial reuse as daily cover for landfills to prevent birds and other wildlife from entering the landfill and spreading waste to surrounding areas. The mercury is isolated, retorted and sold back into industry. The end caps and other ferrous and non-ferrous metals are also removed and returned to industry.
