台灣目前面臨自然資源耗竭及建築材料缺乏問題，明顯地，這些資源主要會影響營建工程，再者，天然資源的過度開發也會破壞環境，嚴重影響水土保值。 玻璃是相當古老的人造材料，它製成許多不同的形狀，包含玻璃容器、平板玻璃、電燈泡和陰極射線管等，這些依其形狀均有不同的使用時間。因此，玻璃必須再利用/再回收，以避免當作垃圾加以填埋，造成環境的負荷。理論上，玻璃是百分之百可回收的物質。它可無限次的回收，而不失去其品質。廢玻璃回收乃是將廢玻璃轉變成為有用的產品。 台灣目前每年皆產生極大量之廢玻璃，這些廢玻璃若能有效加以回收再利用，則對環境保護與資源運用之效率皆有極大的幫助。在廢玻璃處理製程中，必須先進行分色處理，才具備較高的經濟價值。容器玻璃顏色上，一般皆分為白色、綠色及茶色三大類，且需先將雜物加以除去，並且依照顏色加以分類，增加回收玻璃的附加價值。原初，用人工分色，其分色度只有70%，藉由自動化光選設備之導入，分色度由70%提高到90%，提高400萬之產值。另外又節省五位員工，節省200萬元薪資的支出，接著選定一個雜訊因子(天氣)和3個控制因子，利用L8直交表進行實驗，找出最佳控制因子水準組合，使得分色度再由90%提高到95%，再提高100萬之產值，合計每年提高700萬之產值，提升經濟效益並成功地讓台灣玻璃廢棄物能夠順利地資源化再利用。

Taiwan is currently facing dwindling natural sand resources, as well as a shortage of qualified building material supplies. Apparently, the ‘‘resources” have been one of the major considerations affecting construction projects. In addition, over-exploitation of natural sand has led to damage in the environment, seriously affecting water and soil preservation as well as the ecological balance. Glass is one of the oldest man-made materials. It is produced in many forms, including packaging or container glass, flat glass, bulb glass, and cathode ray tube glass, all of which have a limited life in the forms in which they are produced. Hence, glass need to be reused/ recycled in order to avoid environmental problems that can be created, if they will be stockpiled or sent to landfills. Theoretically, glass is a 100% recyclable material; it can be indefinitely recycled without any loss of quality. Glass recycling is the process of turning waste glass into usable products. Waste glass should be separated by chemical composition. Also, depending on end usage and local processing capabilities, it should be separated into different colors. Sorting waste glad by color will increase its added value. Originally, color separation was done by manually. However, the degree of color separation was 70%. The degree of color separation increases from 70% to 90% immediately by introducing a new machine which can separate the color of waste glass automatically. It increases 4 million NT dollars per year. Also, five direct labors was reduced due to automatic equipment. It will save 2 million dollars per year. Next, in order to increase the degree of color separation, one noise factor (weather) and three control factors were selected. An L8 orthogonal array is provided by using Taguchi method to find out the optimal factor level combination. The results show that degree of color separation increase from 90% to 95%. It increases one million NT dollars per year. Thus, the total benefits are 7 million NT dollars per year. It successfully recycles waste glass and facilitates the environment friendly. 行政院環境保護署計畫成果中英文摘要（詳細版）格式範
