ABSTRACT:
A mobile vehicle containing fluorescent lamp separation apparatus is transported to the site of a facility which uses fluorescent lamps and collects used lamps for processing. The lamps are loaded into a bin in the vehicle, the bin is closed to enclose the apparatus from the atmosphere, and the apparatus is then operated to crush the lamps and separate the crushed lamp debris into solid particular matter and dust which can be carried by airflow. The particulate matter which is substantially cleansed of mercury and phosphor powder is discharged into a first receptacle outside the vehicle, and the dust entrained in the air is trapped in a dust filter and discharged into a second receptacle which primarily contains the more hazardous dust materials. The air drawn through the dust filter is further passed through a charcoal filter to filter out mercury and other potentially hazardous vapors from the air before it is discharged to the atmosphere. The particulate matter in the first receptacle is substantially cleansed of mercury, phosphors and other potentially hazardous materials, and may be disposed of in the same manner as conventional waste. The second receptacle contains the much smaller volume of potentially hazardous phosphor powders, and can be retained at the site of the facility or disposed in an appropriate manner as hazardous waste. After completing processing at the facility site, the vehicle is transported to the site of another facility where the process is repeated, thereby avoiding the need to transport the bulky and fragile fluorescent lamps from the facility at which they are used to a landfill or to a central lamp processing site.
