摘要: The purpose of this study is to obtain useful information for end-of-life (ELV) management through a dismantling survey. Six vehicles, comprising conventional and next-generation (hybrid electric vehicles HEV; EV) ELVs, were dismantled. survey allowed identification material composition parts distribution; For instance, the printed wiring board content ranged from 0.74 4.1 kg 3.8 kg HEV, 7.9 kg EV. Resource and/or toxic contents also estimated per ELV at an elemental level, using chemical analysis data previous studies. Rare earth element (REE) 3100 g HEV 710 g EV, compared with 22–64 g vehicles. Precious metal (sum Rh, Pd, Pt, Ag, Au) 3.1–9.6 g. Brominated flame retardants detected 13 interior materials. Related ELV, tended contain wider variety elements in higher amounts than did In some including REEs significant variations noted among studies on ELVs reported so far; these uncertainties should be considered life cycle assessments recycling schemes.
