In an article in the Vancouver Sun, researchers at the University of British Columbia recovered copper, silver, and rare earth metals from LED (light emitting diode) lights recycled "using techniques like the ones employed by the mining industry" to finely grind them up. British Columbia's LightRecycle product stewardship program run by ReGeneration recycles "all lights, lamps, fixtures and ballasts used in residential, institutional, commercial and industrial applications" including LEDs, incandescent lights, and halogens, as well as mercury-containing fluorescent and HID lights.
