從1990年代個人電腦普及以來，電子垃圾產生了嚴重的環境問題，其中尤以廢電腦的影響為鉅。2001年美國發動The Computer Take Back Campaign (CTBC)來推動製造商處理其生產的有毒性電腦廢棄物。其後歐洲提出「生產者責任延伸(extended producer responsibility, EPR)」法規，並在2003年歐盟宣布施行「廢電子電器回收指(Directive on Waste Electric and Electronics Equipment, WEEE)」。再加上我國國內亦繼此世界趨勢陸續頒布廢容器、廢汽機車、廢家電產品及廢電腦強制回收再生的法規，也因此舊廢產品的回收逆物流處理能力對我國電子電器及資訊產品廠商就顯得益發重要。 但現行電子產業中絕大部分的廠商都是採「出售商品」的事業模式，製造商難以掌握產品售後流向、進而回收其舊廢產品。且關於此類電子資訊產業如何佈建一個具獲利基礎的封閉式供應鏈、以及實施的狀況與程序之相關研究甚少。於此，本論文欲探討：對電子產業來說，在哪些條件之下才能達成封閉式供應鏈？其中的關鍵因素又為何？盼能透過個案研究的方式，從實務上的運作狀況探討其中的原因。 本研究選擇重視全球環保及永續發展的華碩電腦，以及在逆物流回收實施領域施行多年且成效顯著的Dell電腦做為個案研究的對象。本研究架構乃依據文獻分析結果，從驅動個案公司進行產品回收的力量開始分析，進一步檢視個案公司的回收再生策略，並從訪談及其他文獻資料內容中分析有哪些重要因素會影響個案公司達成封閉式供應鏈，這些要因會根據第二章歸納出的四大面向為基礎進行比較。最後，根據分析結果評估個案公司在封閉式供應鏈的完成度與績效表現。 / Since 1990s, the electronic wastes (e-wastes), especially PCs and laptops, have caused serious environmental problems. In 2001, the Computer Take Back Campaign (CTBC) initiated and asked the PC manufacturers to be in charge of toxic e-wastes that they produced in the U.S; in 2003, the European Union declared the Directive on Waste Electric and Electronics Equipment (WEEE); besides, Taiwanese government also put the recycling laws into practice, requiring that the wasted containers, cars and motorcycles, electronic products and PCs should be recycled. Therefore, the capability of managing e-wastes has become more and more crucial for Taiwanese PC manufacturers. For those manufacturers who sell out electronic products, it’s difficult to track and recycle their wasted products. Furthermore, there are few researches discussing about how to build up a profitable closed-loop supply chain. Therefore, this study will focus on exploring the key success factors for building up a profitable closed-loop supply chain in the electronic industry. In the case study, ASUS Tek Inc. and Dell Inc., both are dedicating great efforts on recycling issues, were chosen to be the case companies. The framework of this study will start from analyzing the drivers of recycling, the recycling strategies, and then generalizing the key successful factors, which are discussed in Chapter 2, for building up a profitable closed-loop supply chains for the case companies. Finally, the study will evaluate the completeness and performance of the case companies.
