摘要

由於台灣近年來經濟發展，先天上有地狹人稠，擁有汽車的民眾比例有偏高，因此車輛報廢後，數量非常可觀。本研究因此針對廢車零件進行分析，以了解不同的回收方式，何者對環境較為友善。本研究利用生命週期方法，針對國內廢車後端回收體系盤查，分析廢車零組件經由拆解後進入粉碎廠，與直接進入粉碎廠兩種國內主要回收方式之差異。結果發現金屬零件不同回收方式的環境污染，各有優劣，依照不同材質結果不同。廢金屬拆解回收能有效節省環境資源且污染排放較低，廢鋁具有最好的環境效益，廢鐵與廢鉛次之。而在經濟的角度上，三者均有利潤，故主管機關只需針對其排放污染進行管控，並輔導研發技術，以便減少其二次污染的產生。

Since Taiwan's economic development in recent years, there are densely populated innate, the high proportion of people own vehicles, after the vehicle scrapped, the number is very impressive. Therefore, this study analyzed for End-of-life vehicle (ELV) metal parts, to find different recycle methods, whichever is more environmentally-friendly. This study using Life Cycle Assessment (LCA) method, inventory the ELV recycle system’s environment data, and survey the scrap metal’s price in the domestic. The results showed that recycling of metal scrap saving environmental resources and less pollution, the aluminum has the best environmental benefits, the iron and lead is second. On the economic point of view, this metals scrap all have profits, so the government just to control the environment pollution, and research and development technology counseling, in order to reduce the generation of secondary pollution.
