Abstract
A process for the environmentally safe disposal of used fluorescent lamp potted ballast assemblies and the like, with the potential for component part reclamation and/or recycling, involving preferred cryogenic freezing of the potted assembly to the extent that the frozen potting becomes sufficiently brittle throughout to enable it to be pulverized away in small particles, cleanly from all the components, with only that component with a hazardous material needing to be incinerated or otherwise environmentally safely disposed of, and with all the other components and parts in condition for salvage, re-use, and/or reclamation.
