- Abstract:
- Gas-discharge lamps form a fraction of waste electrical and electronic equipment (WEEE). They are included in the European WEEE- and RoHS directive. Due to their mercury content, they are classified as hazardous waste and therefore must be collected separately and recycled in a proper manner. Tubular fluorescent lamps are among the best known representatives of these lamp types and produce 70 % of all electric lighting. This thesis discusses existing lamp technologies and the market of electrical light generation, the recycling technologies of gas-discharge lamps in Austria and analyses the composition of the separately collected lamps. Literature research, expert interviews and a standardized sorting analysis were used as methodical approaches. Due to legislative changes, the lighting market is facing a phase-out of the inefficient thermal radiator technologies (incandescent and halogen bulb). The LED technology is gaining importance, the fluorescent lamp serves as a transitional technology. Regarding the recycling sector, dry-shredder methods dominate in Austria, they comply with the recycling quotas and environmental laws. The sorting analysis shows dominance of the long, non-layered, tubular fluorescent lamp and the energy-saving lamp in weight percent and lot size. The “historical” and “non-historical” lamps are almost equally divided in terms of lot size. Two manufacturers dominate the market in weight percent and lot size, these manufacturers are dominant throughout all other lamp types. Depending on the collection boxes, the ratio of broken lamps and contamination is between five and 20 %. LED lamps play only a minor role within the collection system.
