摘要

根據台灣資源再生協會2008年調查估算，台灣每年產出之中間產品（或粗料）之含銅量約7～8萬公噸；另外，銅品位低廢棄物之含銅量也達2～3萬公噸。換句話說，台灣已有一座年產量約10萬公噸銅量之都市銅礦山。從供給面、技術面、經濟面及環保面等層面來探討其可行性，結論是可行的！1.銅冶煉技術是適合運用於台灣二次銅資源再生循環體系，而且其技術成熟度更勝於以天然銅資源為進料之流程。因其流程操作性較佳且進料銅含量較高、低污染性等優勢。2.台灣現況是只有「二次銅資源」，並不產出銅礦石。如果在國內設置以「二次銅資源」為主要原料之銅冶煉廠，其經濟效益將遠高於送往國外銅冶煉廠處理者。3.二次銅使用率較高國家均非原生礦主要產國，可知在兼顧經濟持續發展及銅礦源缺乏前提下，其發展值得借鏡且符合國際資源化環保趨勢。4.台灣資源再生協會已結合有意願業者，正進行「建構國內二次銅資源循環體系」先期計畫，期盼藉由此工作推動，提供國內相關業者更大發展空間及機會；同時導引國內既有生態能趨於整合或分工方向來提高「雙贏」之可行性。

According to the estimation made by The Formosa Association of Resource Recycling in 2008, the annual copper content of the intermediate goods (or coarse materials) in Taiwan is around 70 to 80 thousand tons and the low grade copper wastes is 20 to 30 thousand tons. Taiwan could be an urban copper mine producing 100,000 tons of copper annually. We explored the feasibility of a domestic secondary copper recycling system and found it economically and environmentally beneficial.1. The secondary copper recycling system utilizes a copper smelting technique with simpler protocols. The system has a relatively higher yield and lower environmental pollution.2. Rather than relying on foreign refineries, the establishment of a local copper refinery specifically for processing secondary copper supply can result in greater economic benefit.3. In order to overcome copper deficiency and maintain proper economic advancement, the copper recycling system merits further development and is in accordance with the international environmental trend.4. The Formosa Association of Resource Recycling has recruited interested investors and is currently working on a preliminary plan for constructing domestic secondary copper resource recycling system. Through this project, the association hopes to provide related industries with opportunities for further development and improvement, while simultaneously advocates environmental-friendly methods to create a win-win situation.
