What Is Universal Waste?

Drum-top crushers (DTCs) are devices that fit on the top of a 55-gallon drum and crush fluorescent lamps into the drum; they are used to improve waste lamp storage and transport.
The Mercury Lamp Drum-Top Crusher Study provides the most current information on the performance of DTCs. The Study provides information on mercury emissions control effectiveness for DTCs. EPA believes that with the information from the Study, states, users of mercury-containing lamps, and lamp recyclers will be able to make more informed decisions when managing fluorescent lamps.
EPA does not endorse nor discourage the use of DTCs.
