| 摘要: | 循環經濟是實現聯合國永續發展目標及淨零排放的關鍵途徑，透過資源有效利用與循環再生，有助減廢降碳並強調廢棄物高值再利用。臺灣政府將「資源循環零廢棄」列為2050淨零轉型的核心策略，其中半導體產業是臺灣核心的科技產業，其製程產生的無機氟化鈣污泥，過去大多直接掩埋或焚化，造成資源浪費及環境負擔。
隨著全世界國家尋求循環經濟作為改善環境條件的路徑，將廢棄物資源化並重新導入產業鏈的創新做法備受重視。氟化鈣污泥再生利用製成人造螢石的再生技術，具備：循環經濟追求資源效率最大化、再生技術發展與創新商業模式等三大要素。在資源效率方面，透過將廢棄物轉化為具經濟價值的產品，大幅提升了資源的使用效率，且製程較傳統開採環保，有助於減少溫室氣體排放；再生技術發展方面，隨著半導體產業的蓬勃發展，此再生技術的推展也促進更多業者投入循環經濟的產業鏈中；在商業模式創新上中，此案例串聯半導體業與鋼鐵業，建構跨產業的資源循環利用價值鏈，為相關業者開拓新商機。透過再生利用技術，將氟化鈣污泥製成人造螢石，供應鋼鐵產業作助熔劑使用，提高資源使用效率、減少環境衝擊、促進再生技術發展、建構跨產業循環價值鏈開拓新商機，此案例展現將廢棄物高值化再利用對實現循環經濟的貢獻。
本研究結論指出，人造螢石若能在品質和價格上達到競爭力，將為鋼鐵業帶來降低生產成本和減少環境負擔的雙重效益，從而增加其使用誘因。螢石業者欲成功推廣人造螢石，需著重於提升產品品質以符合煉鋼需求，同時優化生產技術以提高螢石純度。此外，確保原料供應穩定、實現規模經濟效應及加強行銷推廣也是關鍵因素。
循環經濟的發展需有政府的全方位支持。政府應在技術支援、財務補貼、法規調整和宣導推廣等方面提供協助，以增強再生品的市場競爭力。同時，通過財稅優惠政策和設立強制使用比例等措施，政府可進一步推動再生產品的市場擴展。透過政府協調整合相關的合作單位，更能成功推動循環經濟再生利用模式，最終實現減少廢棄物、節約能源、降低碳排放，並促進綠色經濟發展的多重目標。
本研究旨在探討將半導體業的氟化鈣污泥再生利用製成人造螢石，應用於鋼鐵業作為助熔劑時，此再生產品對於循環經濟政策的貢獻與再生品的應用及發展。期望本研究結果能為相關產業規劃循環經濟轉型策略時，帶來新的視角，並為循環經濟商業模式的討論增添實證案例，有助於推動台灣永續發展與淨零排放願景的實踐。
Circular economy serves as a crucial pathway towards achieving the United Nations' Sustainable Development Goals and net-zero emissions. Through efficient resource utilization and recycling, it aims to reduce waste, lower carbon emissions while emphasizing high-value reuse of waste materials. In Taiwan, the government has positioned "Zero Waste in Resource Circulation" as a core strategy for the 2050 net-zero transition. The semiconductor industry, a key technology sector in Taiwan, generates inorganic calcium fluoride sludge during its processes, which has traditionally been directly landfilled or incinerated, resulting in resource waste and environmental burden.
As global efforts to improve environmental conditions, there is increasing recognition of innovative practices that recycle waste resources and reintegrate them into industrial supply chains.The regeneration technology of calcium fluoride sludge into artificial fluorite incorporates three major elements: maximizing resource efficiency as pursued by the circular economy, advancing recycling technologies, and innovating business models. In terms of resource efficiency, transforming waste into economically valuable products significantly enhances resource use efficiency, and the process is more environmentally friendly than traditional extraction methods, helping reduce greenhouse gas emissions. In the aspect of technological development, the promotion of this regeneration technology, driven by the booming semiconductor industry, encourages broader participation in the circular economy. Regarding innovative business models, this case highlights the integration of the semiconductor and steel industries, create a cross-industry resource recycling value chain, thus opening new business opportunities for new business opportunities. By using regeneration technology to convert calcium fluoride sludge into artificial fluorite for use as a flux in the steel industry, it enhances resource efficiency, reduces environmental impact, promotes technological development, and establishes a cross-industry circular value chain, creating new business opportunities. This study shows the contribution of high-value reuse of waste to achieving a circular economy.
The conclusion of this study indicates that if artificial fluorite can achieve competitiveness in quality and price, it will provide the steel industry with dual benefits of reduced production costs and lower environmental burden, thus increasing its adoption incentives. To successfully promote artificial fluorite, fluorite producers must focus on improving product quality to meet steelmaking requirements while optimizing production technology to enhance fluorite purity. Additionally, stable raw material supply, achieving economies of scale, and strengthening marketing are also critical factors.
The development of the circular economy requires comprehensive government support. This includes assist with technical support, financial subsidies, regulatory adjustments, and promotional campaigns to enhance the market competitiveness of regenerated products. Moreover, government incentives such as tax benefits and mandatory usage quotas can further expand the market for regenerated products. By coordinating and integrating relevant various stakeholders, the government can more successfully promote the circular economy's regeneration utilization model, and achieving multiple goals of reducing waste, saving energy, lowering carbon emissions, and fostering green economic development.
This study aims to explore the contribution of regenerated products to circular economy policies and the application and development of these products by examining the reuse of calcium fluoride sludge from the semiconductor industry to produce artificial fluorite as a flux in the steel industry. This findings hope to provide new perspectives for planning circular economy transformation strategies in related industries and add empirical evidence for discussions on circular economy business models, thereby supporting the realization of Taiwan's sustainable development and net-zero emission goals. |
