Description: Es wird eine mobile Anlage zur vollstaendigen stofflichen Verwertung von Leuchtstoffroehren errichtet. Im ersten Arbeitsschritt werden die Endkappen abgesprengt. Anschliessend werden die Lampeninhaltsstoffe (Quecksilber und Leuchtstoffe) durch einen Luftstrahl ausgeblasen. Quecksilber und Leuchtstoffe werden getrennt erfasst und der Verwertung zugefuehrt. Das Glas wird zerkleinert und kann als hochwertiges Lampenglas in die Leuchtstoffroehrenproduktion zurueckgegeben werden.

Title: Reduction of environmental pollution caused by the mercury load from waste disposal plants as in the example of used fluorescent tubes
Description: *Strategies to collect mercury gas discharge fluorescent lamps at the end of life (EoL) were developed as well as methods for a safe and economic transportation of EoL- fluorescent lamps enabling a direct treatment in recycling facilities. The methods were tested on large scale and implemented in the waste management market in Germany. Cap-cutting technology for recycling of spent fluorescent lamps was developed and successfully verified in a large scale recycling plant: 1670 metric tons of glass products were recycled to glass manufacturing facilities of Os-ram for new fluorescent lamps. Average Hg-content was 3-4 mg/kg glass which was burned into the glass matrix, 1-2 mg/kg glass which was on the surface of the recycled glass. Analytical monitoring of recycling glass must consider the heterogene character of glass from spent fluorescent lamps due to the scattering Hg-values of individual samples. The Hg- content of the fluorescent powder was 0.22 percent, equalling 75 percent of the total Hg in a fluorescent lamp. Fluorescent Powder was discharged as hazardous waste. The removed ends of the glass tube and the metal cups were not recycled. For the treatment of this components shredder processes are meanwhile available, developed by third parties. Filtering processes were installed and tested successfully which reduce the emissions of a recycling plant for spent fluorescent lamps to extremely low levels: smaller than 0.1 mg dust and smaller than 0.01 mg Hg per cubic meter of exhaust air, however, no measuring device had been found to monitor such low amounts of vapor phase mercury exactly in continuous Operation.
