LED照明光源相對於傳統照明更加環保且耗電量更少，近年來其使用量正逐年增長。使用後廢棄的 LED照明光源的數量也逐年上升中。 自民國107年起我國已開始回收處理LED廢照明光源。目前在資源材數據、資材再利用技術能力及產業鏈體系的健全化尚未完整建立；在淨零永續國際風潮下，開發LED廢照明光源資源循環相關技術及產業鏈，以及評估其相關應用之低碳利益深具迫切性。 本計畫主要工作項目包括：A. LED廢照明光源有價金屬組成與特性分析，B. 廢鋁金屬回收處理與再利用技術開發，以及C. LED照明光源再生塑料/應用產品碳足跡及其低碳利益評估等。 本研究團隊現階段已完成：(1)LED照明光源資源材組成分析數據資料建立，(2)廢鋁金屬再生料再利用技術開發(包括：熔解回收法再生鋁錠試製、廢鋁鋁水產氫的製備等)，(3)廢鋁金屬再生產品應用效益的評估(包括：再生鋁錠、氫氣及氫氧化鋁沉澱產物等)，(4)鏈結LED照明光源廢鋁金屬資源循環產業相關業者，以及(5)LED廢照明光源再生PC塑粒及廢PS塑膠於仿實木應用，產品的碳足跡試算及其低碳利益評估等。期望藉由本研究計畫，能提升國內 LED照明光源廢鋁金屬再利用管道的多元性及其應用價值，並協助國內 LED照明光源回收產業建立新的循環價值鏈。

LED lighting sources have become increasingly popular in recent years due to their environmental friendliness and lower power consumption compared to traditional light sources. Consequently, the volume of discarded LED lighting sources has also been rising annually. Since 2018, Taiwan has begun recycling and processing waste LED lighting sources. However, a comprehensive data system for resource materials, recycling technology capabilities, and a sound industrial chain system have yet to be fully established. Under the global trend of net-zero sustainability, developing technologies and industrial chains related to the resource cycle of waste LED lighting sources, as well as assessing their related low-carbon benefits, is highly urgent. The main tasks of this project include: A. Analysis of the composition and characteristics of valuable metals in waste LED lighting sources, B. Development of recycling and reutilization technology for waste aluminum metal, and C. Evaluation of the carbon footprint and low-carbon benefits of recycled plastics and the application products from LED lighting sources. Our research team has currently completed: (1). Establishment of a database of resource material composition analysis for LED lighting sources, (2). Development of recycling technology for waste aluminum alloy (including demonstration of small batch production of recycled aluminum ingots through melting route and reuse of waste aluminum as hydrogen production through aluminum water reaction), (3). Evaluation of the application benefits of recycled aluminum products (including recycled aluminum ingots, hydrogen, and aluminum hydroxide precipitates), (4). Linking with relevant industry players in the resource cycle of waste aluminum metal from LED lighting sources, and (5). Carbon footprint calculation and low-carbon benefit assessment of recycled PC plastic pellets from waste LED lighting sources and waste PS plastic in imitation wood applications. It is hoped that through this research project, the diversity of recycling channels and application value of waste aluminum metal from LED lighting sources in Taiwan can be enhanced, and a new circular value chain for the domestic LED lighting source recycling industry can be established.
