A wheeled portable unitary apparatus is provided herein for disposing of hazardous light bulbs, e.g., fluorescent bulbs. The apparatus includes an open- topped, multi-compartmented container of cylindrical cross-section which are separated by an air permeable disc. The container includes an upper collection compartment, and a lower exhaust compartment. A lid is hingedly-connected to, and is adapted to cover, the top of the container. The lower surface of the lid is connected to a reduction chamber, the reduction chamber having an axial inlet means for a cylindrical bulb to be pulverized and an axial outlet means leading to the collection compartment. An electric motor which is provided with an on/off switch, is disposed within the reduction chamber and has a rigid unitary pulverizing blade secured to its drive shaft. The reduction chamber is bounded by an open bottom cylindrical protective guard. A cylindrical plastic insert covers the open top of the upper collection compartment and has an automatically-reclosable central opening therethrough through which the open bottom of the cylindrical protective guard sealingly projects. A cylindrical light bulb feed chute extends through the lid and is attached thereto, to feed cylindrical light bulbs to the reduction chamber. A disposable pulverized light bulb collection bag is selectively disposed within the upper collection compartment in air-sealed relationship to the open bottom of the cylindrical protective guard. A vacuum generator is operatively associated with the lower exhaust compartment to subject the lower exhaust compartment to sub-atmospheric pressure. The lower exhaust compartment also includes a filter member extending transversely across the compartment to divide that compartment into an upper vacuum chamber and a lower chamber. The upper vacuum chamber includes a vacuum hose connected between an upper radial outlet port and extending through the lid to communicate with the reduction chamber to purge any hazardous materials which may be within the reduction chamber into the upper vacuum chamber. The lower chamber includes filters across the lower radial outlet port, whereby the lower vacuum chamber discharges environmentally-clean gases to the environment.
