What happens to CFLs or other fluorescent light bulbs when they are recycled?
Virtually all components of a CFL or other fluorescent light bulb can be recycled. The metal end caps, glass tubing, mercury and phosphor powder can all be separated and reused. Recyclers often sell the metallic portions as scrap metal. The recycled glass can be remanufactured into other glass products. The mercury can be recycled into new fluorescent light bulbs and other mercury-containing devices.
