由於臺灣電子工業的蓬勃發展，印刷電路板的需求量成長相當快速，紙基材酚醛銅面積層板是現今民生消費性電子產品和相關資訊、通訊週邊產品的關鍵材板。相對的，生產過程所產生的廢棄物處理也成為一個嚴重的問題。本研究以紙基材酚醛樹脂銅面積層板工廠廢棄物為對象，將廢棄銅絲（粉）子以資源化。經實驗結果顯示，以30目篩網配合沉降分級機可將銅絲（粉）有效分離，其回收率可達全部銅含量之99％以上。如此可減少廢棄物的處理數量，同時可以大幅降低此等有害事業廢棄物之處理費用。

Paper-phenolic copper clad laminate is main raw materials of consumer electronics, information and telecommunications devices. To treat the laminate waste is also an important issue. This research work was to develop a separation process to recycle copper from the laminate wastes. According to the experimental results, copper can be separated using screen (30 mesh) and hydraulic classifier. The total copper recovery can be reached up to 99 percent. Therefore, the waste treatment cost would be reduced.
