Waste Fluorescent Lamp Recycling

The aim of this paper was to identify possible improvements of fluorescent lamps recycling technology to produce broken glass categorized as non-hazardous waste, and to effectively remove phosphorus powder contaminated with mercury, providing reuse of aluminum as secondary raw. This paper investigates and compares the effectiveness of mercury removal by recycling fluorescent lamps in 2 plants with the intent to improve existing technologies. Due to the high mercury residual content in eluates of the sample from the plant A and B, removal of mercury is examined by heating in laboratory conditions to improve mercury removal. These results indicate that optimizing the speed of the drum and upgrading additional drum heater can improve recycling technology and reduce amount of mercury. Considering the energy and economic aspects, the optimum heating is shown at 80 ° C with retention time of 15 minutes.
