LED (Light Emitting Diode)照明光源，相對於傳統光源更為環保省電，近年來其使用量逐年增長。2024年LED在我國光源市場的市占率將有機會突破 8成；LED照明光源之廢物流數量正逐年上升中。因此開發適當之回收處理策略與再利用技術，已是國際共同努力的目標。 目前各國已將 LED光源納入廢照明光源範圍，進行回收處理，並訂有相關回收法令規範。我國環保署亦已公告自民國 106年1月1日起全面回收廢棄 LED光源，並從 107年起開始實施。 目前國內已有 LED廢照明光源回收處理廠商。但因目前分選效率還不夠高，導致回收料尚有混雜之問題，以致影響後端的再利用。特別是廢塑膠料，目前去化仍不易或僅能當輔助燃料。另外，以現行回收處理的方式仍有 50%物料須經由人工分選，以致處理成本偏高。此皆影響處理業之回收意願。 為了解決以上之問題，本計畫擬開發 LED廢照明光源塑膠燈罩處理技術，包含：LED廢照明光源廢塑膠種類及成分研析、廢塑膠分選、塑膠燈罩分離技術之探討，以及後端的再利用技術開發等。本計畫目前已完成(a). LED照明光源塑膠種類分析，(b). 廢塑膠燈罩成分及特性解析，(c). 塑膠燈罩物理拆解雛型機構的建立與驗證，(d). 廢燈罩再生粒料的試製，(e). 該再生粒料2項應用產品的可行性評估，(f). 產業鏈結8家相關廠家的訪視及意見收集等。本研究可提升國內 LED照明光源廢塑膠再利用管道的多元性及其應用價值。

Compared with traditional illumination light sources, LED lighting sources are more environmentally friendly and consume less power. In recent years, their usage is increasing year by year. A report pointed out that by 2024, in Taiwan the illumination lighting source market share of LEDs will have the opportunity to exceed 80%. The waste stream of LED lighting sources is increasing year by year. Therefore, the development of appropriate recycling and treatment strategies as well as reuse technologies has become the same goal of international countries. Currently, many countries have legislated that waste LED lighting sources should be recycled as traditional lighting sources, and have established relevant recycling specifications. In Taiwan, The Environmental Protection Agency has also announced that the waste LED lighting sources should be recycled from January 1, 2017, and prepared to first process the waste LEDs from 2018. In Taiwan, there are few companies is currently engaged in recycling of waste LED lighting sources. In addition, because these recycling companies are still beginners in LED-recycling, they still lack of good technique and equipment for sorting of various different plastics, that results in mixture of various different kinds of plastics after waste LEDs were crushing treated. This make it difficult to reuse and apply the recycled plastic of waste LEDs, not to mention that some kinds of waste plastics are difficult to dissolve, resulting that they usually can only be energy recycled as an auxiliary additive into an incinerating fuel. One of the main source of waste plastic is from lampshade components. Based on current recycling method, 50% of the crushed mixtures still have to sort manually, resulting in high processing costs. Those reasons mentioned above decrease the willingness of domestic companies to engage in recycling of waste LED plastics. In order to solve the above problems, this project will focus on developing the recycling technology of plastic lampshade for waste LED light sources. The content of the project will include investigation in waste plastic types and composition of waste LED light sources, analysis of plastic composition, sorting of waste plastic, and technology improvement in separation of lampshade plastic. We have completed the followings in this project (a). Analysis of the plastics types used in LED lighting sources, (b). Analysis of the compositions and characteristics of waste plastic lampshades, (c). Establishment and verification of a prototype mechanism for physical dismantling of plastic lampshades, (d). Trial production of recycled plastic pellets from the waste lampshade, (e). Feasibility assessment of two applications of the recycled pellets. (f). Interviews with eight related manufacturers and collection of their opinions, in order to construct local industrial supply chain etc. Through this research project, we expect to improve the recycling value of domestic LED waste plastic, and to diversify their application domain.
