中文摘要	我國廢電冰箱處理廠每年產生約6,000公噸的硬質聚氨酯隔熱泡棉(PUR)，目前去化管道有限且尚未進行資源化利用。本計畫旨在評估開發廢電冰箱PUR之高值循環利用技術，參考國際經驗透過物理及化學回收方法，將廢PUR轉化為可循環利用之材料或原料，並再製成市場可接受之應用產品，以期降低焚化爐負荷及增加循環經濟效益。　　本計畫已初步建立廢PUR高值化循環利用技術之製程參數，透過測試物理回收及化學回收方法不同的操作條件與原料取代量，確認廢PUR循環再製材料或原料具技術可行性。物理回收技術測試結果發現，SIb4改質方法表現最佳，相較於添加無改質之PUR，發泡體的機械強度可由82%提高至101%。化學回收採兩階段醇解製程設計，實驗結果發現DEG系統可獲得OH較低之醇解產物，以添加20%再生多元醇進行發泡試驗，發泡體的隔熱效果及抗壓強度皆較完全使用新鮮原料表現更佳。最後以添加15%改質後之PUR粉進行仿木家具試製，共完成方桌椅組、會議長桌、咖啡桌等3款PUR再生循環產品製作，相關成果可作為未來製程優化與規模放大之參考數據，以落實資源永續循環之目標。

　　我國廢電冰箱處理廠每年產生約6,000公噸的硬質聚氨酯隔熱泡棉(PUR)，目前去化管道有限且尚未進行資源化利用。本計畫旨在評估開發廢電冰箱PUR之高值循環利用技術，參考國際經驗透過物理及化學回收方法，將廢PUR轉化為可循環利用之材料或原料，並再製成市場可接受之應用產品，以期降低焚化爐負荷及增加循環經濟效益。　　本計畫已初步建立廢PUR高值化循環利用技術之製程參數，透過測試物理回收及化學回收方法不同的操作條件與原料取代量，確認廢PUR循環再製材料或原料具技術可行性。物理回收技術測試結果發現，SIb4改質方法表現最佳，相較於添加無改質之PUR，發泡體的機械強度可由82%提高至101%。化學回收採兩階段醇解製程設計，實驗結果發現DEG系統可獲得OH較低之醇解產物，以添加20%再生多元醇進行發泡試驗，發泡體的隔熱效果及抗壓強度皆較完全使用新鮮原料表現更佳。最後以添加15%改質後之PUR粉進行仿木家具試製，共完成方桌椅組、會議長桌、咖啡桌等3款PUR再生循環產品製作，相關成果可作為未來製程優化與規模放大之參考數據，以落實資源永續循環之目標。

摘要	Each year about 6,000 tonnes of rigid polyurethane (PUR) was produced from the dismantling of waste refrigerators. Meanwhile, the final treatment method of waste PUR is very limited, and waste PUR has not been recycled or reutilized at all. The project aims to develop a high-value recycling technology for waste PUR based on the physical and chemical recovery methods adopted in Europe. Waste PUR will be converted into recycled materials or products with market approval. Therefore, reduce the use of incinerators and increase the economic benefits of recycling. 　　The aim of this project is to establish the processing parameters for converting waste PUR into high-value recycled materials or products. The physical and chemical properties of the recycled PUR powder had been examined first. The effectiveness of different modification methods were then tested and it was found that modification method SIb4 showed the best performance, as the mechanical strength of the recycled foam improved from 82% to 101%. In terms of chemical recycling, a two-stage glycolysis process was adopted, and the use of diethylene glycol (DEG) was found to be most efficient. In the foaming test with adding 20% recycled polyol, better performance was observed regarding heat insulation and compressive strength than that of using fresh raw materials. Based on the results of physical recycling, 3 sets of tables were produced by adding 15% modified PUR powder. The outcome of this project is expected to be used in the future for process optimization and industrial scale-up to achieve sustainable development and circular economy.

　　Each year about 6,000 tonnes of rigid polyurethane (PUR) was produced from the dismantling of waste refrigerators. Meanwhile, the final treatment method of waste PUR is very limited, and waste PUR has not been recycled or reutilized at all. The project aims to develop a high-value recycling technology for waste PUR based on the physical and chemical recovery methods adopted in Europe. Waste PUR will be converted into recycled materials or products with market approval. Therefore, reduce the use of incinerators and increase the economic benefits of recycling. 　　The aim of this project is to establish the processing parameters for converting waste PUR into high-value recycled materials or products. The physical and chemical properties of the recycled PUR powder had been examined first. The effectiveness of different modification methods were then tested and it was found that modification method SIb4 showed the best performance, as the mechanical strength of the recycled foam improved from 82% to 101%. In terms of chemical recycling, a two-stage glycolysis process was adopted, and the use of diethylene glycol (DEG) was found to be most efficient. In the foaming test with adding 20% recycled polyol, better performance was observed regarding heat insulation and compressive strength than that of using fresh raw materials.
