Gas discharge lamps
This category includes fluorescent tubes and low energy light bulbs, also known as compact fluorescent lamps (CFL), while old-style filament light bulbs and halogen lights are not categorised as WEEE.
Lamps are crushed and washed or treated in pressurised containers. Specialised machines are used to remove the hazardous mercury and phosphor. Then, the remaining material is sorted into glass, metals and plastics.
Phosphor powder and recovered mercury can be re-used to make new lamps. The crushed glass can be used for furnace linings or, if pure enough, to make new lamps. Aluminium end caps are smelted and other metals are recycled.
