Abstract:	國內近年因廢棄物無法有效處理，導致廢棄物任意棄置問題浮現。主要原因來自於廢棄物相關處理設施不足、掩埋場飽和及廢棄物焚化爐機械老舊等因素，顯然既有廢棄物處理模式已不能滿足社會需求，如何將廢棄物進行有效處理為極需探討之課題。本研究主要探討國內廢棄物經由機械分選技術製成固體回收燃料（Solid Recovered Fuel，SRF），供燃煤鍋爐、發電廠及水泥窯做部分燃料使用之可行性，並進一步探討對降低環境衝擊和節省成本之效益。研究目的包含（1）針對國內一般廢棄物處理現況進行分析；（2）探討SRF應用之效益；以及（3）SRF應用於台灣之可行性分析。經由研究分析，若使用SRF替代既有生煤時達10%時，燃料費用可節省3%，重金屬可減少8.7%，CO2排放量可減少6.5%；若完全替代時，燃料費用可節省30%，重金屬可減少87%，CO2排放量可減少65%。可知使用端若添加部分SRF替代燃煤，對經濟和環境之效益皆為正面。而國內SRF推行目前面臨下列問題尚待解決：（1）缺乏SRF之觀念及規範；（2）中央政策與地方政府互動不良及法規解讀落差；（3）無相關政策補助或獎勵金；（4）鍋爐混燒燃料衍生廢棄物之配套問題無法解決；以及（5）民眾對廢棄物的處理認知不足。最後，對於SRF導入台灣之應用提出以下小結：（1）目前國內仍缺少SRF之成功案例，應積極向國外相關廠商獲取經驗；（2）國內已有火力發電、水泥窯及汽電共生業者，使用端僅需調整進料設施即可提升產品去化之效用；（3）配合政府循環經濟政策擬定SRF相關規範將有助於國內SRF製造及使用行為。;Owing to the ineffective treatment of waste recently, illegal waste disposal is the major environmental problem in Taiwan. The reasons include the waste related treatment facilities are inadequate, landfills have saturated and waste incinerators have reached the age limit. Obviously, current waste disposal modes are not enough to meet the needs of the society. How to effectively treat wastes is an important issue that needs to be discussed. 　　This study will explore the feasibility of solid recovered fuel (SRF) be made from municipal solid waste and industrial or commercial waste (collectively referred to as waste) via advanced mechanical as using part of the fuel for coal-fired boilers, power plants and cement kilns. Further explore the benefits on reducing environmental impacts and costs. The purposes of this study are (1) to discuss the current situation of waste treatment in Taiwan; (2) to discuss the benefits of SRF applications; and (3) to do the feasibility analysis about introducing SRF applications to Taiwan. According to our research results, while replace 10% of coal with SRF, the fuel costs can be saved by 3%, heavy metals can be reduced by 8.7%, and CO2 emissions can be reduced by 6.5%; If replace 100% of coal with SRF, the fuel costs can be saved by 30%, heavy metal can be reduced by 87%, and CO2 emissions can be reduced by 65%. It can be seen that the economic benefits and environmental benefits of using SRFs instead of burning coal have positive effects. Introducing SRF to Taiwan facing the following problems: (1) lack of SRF concepts and specifications; (2) divergent opinions between central policy and local government; (3) no relevant policy subsidies or incentives; (4) no solutions about boilers co-firing fuel derivative waste; and (5) people’ insufficient knowledge about waste treatment. Finally, this study provides some suggestions about introducing SRF experiences to Taiwan: (1) to actively learn SRF experiences from foreign companies because there are still no successful SRF applications in Taiwan; (2) to improve the effectiveness of waste disposal, users only need to adjust the receiving facilities; and (3) to develop regulations in line with government’s circular economy policies will help the real SRF actions.
