報廢車輛 （End-of-Life Vehicles, ELV） 含有大量可回收材料，是資源循環與廢棄物管理的重要關鍵之一。儘管台灣每年報廢的機車數量龐大，但相較於汽車，其回收與處理的研究與討論仍相對不足。本研究聚焦於台灣地區報廢摩托車的拆解流程，旨在分析現行拆解效率與挑戰，並提出具體優化建議，以提升整體處理效能與環境永續性。
目前台灣機車拆解作業高度依賴人工操作，拆解過程耗時且勞力密集，導致成本升高，進而降低業者參與意願而影響回收率。為深入探討此問題，本研究記錄並分析不同類型摩托車的實際拆解時間，並採用直接測量與拆解難易度指標 （eDiM, ease of Disassembly Metric） 方法進行比較，識別影響拆解效率的關鍵因素。研究結果顯示，「車體 (Body)」類別的零件拆解最為耗時，尤其是車殼，主要因其結構複雜、螺絲數量多且規格不一，需頻繁更換工具，造成拆卸時間顯著增加。此類零件回收價值低，卻占據大量工時，對整體回收效益產生負面影響。
為整合環境與經濟層面的考量，研究亦導入生命週期評估 (Life Cycle Assessment, LCA) 與環境貨幣化方法，將碳排放等環境衝擊做為考量並轉換為經濟價值，以建立回收效益模型。模擬不同再利用情境後發現，適當設定「拆解停止點」可避免資源錯置，提升整體回收利潤與環境效益。研究建議製造商應從產品設計階段納入可拆解性原則，包括螺絲標準化、零件模組化與材料選擇簡化，同時強化與拆解業者間的資訊共享，以共同因應未來資源回收挑戰。研究成果亦適用於電動機車於拆解流程的優化，具備實務推廣潛力與政策參考價值。

End-of-Life Vehicles (ELVs) contain valuable recyclable materials, making them critical to resource recovery. Despite the large number of scrapped motorcycles in Taiwan, research on their dismantling and recycling remains limited. This study investigates the dismantling process of Taiwanese motorcycles, aiming to identify inefficiencies and propose improvements for enhanced sustainability and economic viability. Motorcycle dismantling in Taiwan is labor-intensive and time-consuming, raising costs and discouraging recycling efforts. By recording dismantling times for various motorcycle types using direct measurement and the ease of Disassembly Metric (eDiM), the study identifies key inefficiency factors. Results show that "Body" components—especially outer shells—consume the most time due to complex structures and diverse screw specifications, despite having low recycling value. To integrate environmental and economic aspects, Life Cycle Assessment (LCA) and monetization methods were applied. Scenario analysis suggests that defining a “dismantling cut-off point” can improve overall efficiency and benefits. The study recommends incorporating design-for-disassembly principles, such as screw standardization and material simplification, and enhancing information sharing between manufacturers and dismantlers to meet future recycling challenges. The findings are also relevant to electric motorcycle recycling.
