| Résumé : |
Rarely does a single material meet all automotive engineering requirements. Yet hybrid materials cannot be disassembled manually with reasonable effort, so that production waste is only being used thermally to date. Sensor-assisted plastic sorting however promises good yields and has economic potential. |

- Processing and sorting
- Identifying and separating plastics in headlights
- Recycling in small-scale technical tests
- Potential analysis and economic efficiency
- FIGURES : 1. Mixed waste from headlight production : fully assembled headlights and aluminum-coated plastics - 2. Process concept in the ForCycle project group for recycling headlight production waste - 3. Exemplary composition of a headlight in percentages by weight with differentiated examination of the combined fraction and pure plastic fraction - 4. Separation of metal-plastic composites by leaching : dependency of the leaching time on the concentration of caustic soda - Yields and purities of the fractions after automatic sorting by RTT Steinert : the specified percentage proportions respectively refer to the original input quantity after the separation of fines - 6. Exemplary plastic fractions with purities > 90 % after automatic sorting : PC fraction, PP fraction. For optimum compatibility, the material was shredded after fractioning - 7. Potential analysis of the pure plastic fractions (the 16.5 % proportion of metal is not considered here). Increasing the effectiveness to 80% by optimizing material disintegration is also shown as a realistic scenario - 8. Economic efficiency calculation for the developed automobile headlight recycling process with an annual waste volume of 2000 t/a |
