What are they?
A fluorescent lamp is a gas-discharge lamp that uses fluorescence to produce visible light.
Why do they need to be sorted?
Fluorescent lamp contains mercury, thus, are classified as hazardous waste. The disposal of phosphor and particularly the toxic mercury in the tubes is an environmental issue, thus, fluorescent lamps should be separated from general and household wastes.
How is it recycled?
Fluorescent lamps are fed into a special machine that safely separates the glass, metal, phosphor and mercury preparing them for re-use.
