    Answer:
Drum-top crushing is done using a mechanical device that fits on top of a 55-gallon collection drum. Whole lamps are broken in the system but components are not separated, and the drum will contain hazardous mercury, phosphor powder, glass and mixed metals. Crushing lamps into drums releases mercury into the filter, which also becomes hazardous.
