Mercurycontaining Light Bulb Lamp Basic Information

Crushing is the intentional breaking of fluorescent and other mercury lamps for the purpose of volume reduction. Crushing reduces the physical volume of lamps but does not recover any mercury. Crushing is not recycling, but it can be a step in the process when the crushed material is further treated by a recycling process that includes retorting.
