ABSTRACT:
There is described a process for the disposal and recycling of resistance (or incandescent) and/or discharge lamps by crushing the lamp bodies and separating the glass, metal, heavy metal and, if appropriate, fluorescent components of the lamps by crushing the lamp bodies by means of a squeezing device whose effective distance can be adjusted in such a way that no separation of the base glass and the lamp base will be effected. Another subject-matter of the invention is a squeezing device for carrying out the process, comprising a double-belt press with an adjustable distance between the upper and the lower belt.
