聯合國指出因為經濟的成長，全球總人口數逐年攀升，揭示人口數的增長會加速資源的耗費，廢棄物量及溫室氣體排放量隨之攀升，導致地球已正在面臨「氣候變遷」與「自然資源枯竭」兩大急迫議題。根據聯合國環境署與國際固體廢物協會共同研究報導，全球都市固體廢棄物製造量預測至2050年全球固體廢棄物產量將攀升至38億噸。過往「線性經濟」的產品生命週期為搖籃到墳墓採以「採用-製造-丟棄」的路徑，它無盡到資源循環再利用，為此解決資源浪費、廢棄物增長的議題以提升物質流達到最高效力，將過去的「線型經濟」轉化成「循環經濟」以最降低資源浪費和環境污染。

本研究探討廣泛被常使用的循環經濟商業模式，進一步對固體再生燃料(Solid Recovered Fuel, SRF)產業作為案例討論，深入探究循環經濟商業模式中關鍵之成功因素，並藉由層級分析研究法(Analytic Hierarchy Process, AHP) 分析專家評選出的循環經濟商業模式關鍵因素。從AHP權重結果得出，依據不同產官學界觀點評選出其結果一致性比率(Consistency Ratio, R.I. )。研究彙整出權重順序依序為：1.「廢棄物回收量」、2.「物流與儲存」、3.「材料應用」、4.「降低汙染」、5. 「延長生命週期」、6.「使用方式」、7.「綠色採購」、8.「價值創造」、9.「經濟誘因」、10.「再生利用」。透過本研究提出評析及權重結果，對未來企業組織在定義角色與規劃產品設計提供實質的參考依據。在產品設計過程中，應深思熟慮地選用適當材料種類，突破製程技術限制，引導使用者正確使用產品，延長產品生命週期，最終實現產品的再次利用，以減少廢棄物的產生。同時，必要確保產品符合政府環保政策與法規標準，以達成資源循環、零廢棄的永續目標。

本研究透過AHP研究方法，過程訪談三位專家對於循環經濟的權重排序見解並針對固體再生燃料產業於循環經濟商業模式的應用與建議。本研究發現在台灣SRF尚未建立完善的法規規範，且對採用SRF的企業引導方法不夠明確。SRF不僅是處理廢棄物、節約能源和減少碳排放的關鍵因素之一，也能幫助解決焚化廠處理廢棄物量的問題，並取代燃煤等傳統化石燃料。以SRF能以每1公噸SRF替代0.86公噸的煤炭，進而降低37%的碳排放量，等於減少了0.77公噸的二氧化碳排放。這對於達成全球面臨氣候變遷所推進的淨零排放與資源循環零廢棄的永續目標具有重要意義。

This study aims to explore the critical factors of the Circular Economy Business Models through the Analytic Hierarchy Process (AHP). Aiming to explore the circular economy business models and focuses on the Solid Recovered Fuel (SRF) as a case study, solid waste was defined to the final discarded or unwanted materials; however, SRF creates the waste-to-energy value, effectively in reducing carbon emissions and the environmental pollution. Transform the product life cycle from the "Linear Economy" into the "Circular Economy". This is a great significance to achieve the sustainable goal of Net-zero emissions and Zero-waste resource recycling in the global climate change. The key elements of the circular economy business model, derived from the AHP, are applied to the SRF industry to assist relevant industries, government entities, and academic bodies in constructing strategic circular business models.
