End-of-life vehicles (ELVs) in Kuala Lumpur were quantified with a minimal stock-flow MFA calibrated to 2024 observations. From an in-use fleet of ≈1.7-1.9 million vehicles, annual ELV arisings are ≈40-50 k (≈2-3%). Only ≈2-3 k reached authorised treatment (formal capture ≈4-7.5%); within this, ≈320 were e-deregistration (provisional KL estimate), while ≈2.0-2.4 k originated from DBKL removals that reached treatment. ≈5 k were handled informally/relocated and the residual ≈35–40 k remained dormant. Policy scenarios (2025-2035) scale outcomes with the formal-capture share α: authorised recycling (mass) ≈0.95 α, with landfill diversion and hazardous-fluid capture increasing proportionally. These results identify collection/deregistration and authorised capacity as binding constraints and inform life-cycle engineering (LCE) priorities on design for depollution/disassembly, parts harvesting/remanufacturing, and closed-loop metals, guiding Malaysia’s transition toward a circular automotive economy.
