中文摘要	纖維補強複合材料(以下簡稱纖維複材)因具備優異機械性能，例如：良好的纖維強度、纖維模量及耐腐蝕性等，因此當產品同時需要堅固與耐用等功能時，會選擇纖維補強複合材料做為主要材料。然而，纖維複材的高機械強度與耐腐蝕性亦使其在產品生命週期結束時，複材廢棄物處理與再利用難度會大於其他事業廢棄物。其中，熱固性樹脂基纖維複合材料因固化過程中所產生之化學交聯反應，其不可逆之化學鍵結反應導致纖維複材難以分解處置，其廢棄物處理成為業界面臨之處理難題。目前廢風力葉片複材廢棄物之去化方式係以掩埋、堆放為主，然而國內可利用腹地不足，可預期未來纖維複材廢棄物將成為不可忽視的環境隱憂。本計畫研究玻璃纖維複材最適化低碳資源循環技術，包括(1)鏈結國內水泥產業，建立水泥窯協同處置廢玻纖複材之技術，且為增加後續技術「落地應用」之可行性，規劃與水泥產業進行前期合作，協同辦理1次噸級實廠試燒作業，藉此拓展廢棄纖維複材去化管道；(2)以去化廢風力葉片為實驗主軸發展低碳化學解聚回收技術，透過綠色化學解聚配方在低溫下(<100oC)將廢風力葉片中長纖維和樹脂近全回收，並最大化保有原纖維之機械性質。此外，所開發之綠色化學解聚主劑配方可再生並重複使用，不衍生二次環境污染；回收長纖維可部分取代原生纖維再製成高值化再利用產品，並導入複合材料產業製程中使用。同時透過業界先期技術參與，加速完成再利用產品開發與驗證，完成回收產品高值化佈局，達成「資源極大化」與「廢棄物極小化」之開發目標。

摘要	Fiber-reinforced composite materials, due to their good mechanical performance, high fiber strength, high modulus, and good corrosion resistance, have greater challenges in terms of disposal and recycling. According to variety of composites, the chemical crosslinking bondings of thermosetting composites become strong and irreversible after forming process, which led to a long-term environmental problem of waste disposal at the end of the life cylcle of composites. Currently, the main ways for wind turbine blade wastes involve landfill and piling up. However, due to the limited space in Taiwan, it is certainly sure that the large amount of waste blades will become a serious environmental issue in the near future.This project aims to develop and optimize low-carbon-resource recycling technologies for glass fiber composite wastes. First of all is to establish a collaborative process with the cement industry to develop a cement kiln co-processing technique, and we also plans to conduct a pilot-scale operation in a cement plant in order to examine a practical feasibility. Secondly, a low-carbon chemical depolymerization and recovery technique for wind turbine blade wastes is developed to expand another disposal pathway for waste blades. By green chemical depolymerization formulas, it is aimed to recover a significant portion of the long fibers and resin from the blade wastes at low temperatures (<100°C), while preserving the mechanical properties of the original fibers. Additionally, the developed green chemical depolymerization agents can be repurified and reused without causing environmental pollution. The recovered long fibers possess high potential to replace ner fibers or to be used as raw materials for high-value products, which have a new chance to be employed in the composite industry. By actively involving the industry in the early stages of technology development, one of the aims of this project is to expedite the development and validation of recovered products, achieving high-value utilization of the recovered materials.

摘要

Fiber-reinforced composite materials, due to their good mechanical performance, high fiber strength, high modulus, and good corrosion resistance, have greater challenges in terms of disposal and recycling. According to variety of composites, the chemical crosslinking bondings of thermosetting composites become strong and irreversible after forming process, which led to a long-term environmental problem of waste disposal at the end of the life cylcle of composites. Currently, the main ways for wind turbine blade wastes involve landfill and piling up. However, due to the limited space in Taiwan, it is certainly sure that the large amount of waste blades will become a serious environmental issue in the near future.This project aims to develop and optimize low-carbon-resource recycling technologies for glass fiber composite wastes. First of all is to establish a collaborative process with the cement industry to develop a cement kiln co-processing technique, and we also plans to conduct a pilot-scale operation in a cement plant in order to examine a practical feasibility. Secondly, a low-carbon chemical depolymerization and recovery technique for wind turbine blade wastes is developed to expand another disposal pathway for waste blades. By green chemical depolymerization formulas, it is aimed to recover a significant portion of the long fibers and resin from the blade wastes at low temperatures (<100°C), while preserving the mechanical properties of the original fibers. Additionally, the developed green chemical depolymerization agents can be repurified and reused without causing environmental pollution. The recovered long fibers possess high potential to replace ner fibers or to be used as raw materials for high-value products, which have a new chance to be employed in the composite industry.
