隨著全球科技和文明不斷進步，雖然帶來了便利，但同時也導致廢棄物產量日益增加，如今環保理念抬頭，零廢棄逐漸成為解決廢棄物問題的理想目標。本研究探討結合廢玻璃、牡蠣殼、蛋殼、粉筆灰等四種廢棄物，經高溫處理後燒結成發泡玻璃之可行性，並評估三種發泡劑製成之發泡玻璃是否能成為隔音綠建材，作為環保輕質材料。
本研究首先對原料進行基本特性分析，包含化學組成、水溶性氯離子含量、pH值等。實驗採用三種不同碳酸鈣來源作為發泡劑，搭配固定比例的廢玻璃粉末，進行燒結條件設計（溫度800°C至950°C，持溫10–60分鐘），以探討不同配比與熱處理參數對發泡玻璃之密度、孔隙率、吸水率與筒壓強度的影響。
結果顯示，添加碳酸鈣廢棄物可以成功引發發泡反應，其中以蛋殼及粉筆灰的發泡表現最佳，牡蠣殼雜質及碳酸鈣峰值不高所以發泡效果不顯著，蛋殼及粉筆灰產稱之發泡玻璃以在850°C及900°C下的密度、開孔率、筒壓強度達到最佳。綜合比較之下其發泡劑添加量以3wt%為最適配比。整體而言，本研究證實以廢玻璃與適當碳酸鈣來源製備發泡玻璃具良好可行性，未來具應用於綠建材市場之潛力。

With the continuous advancement of global technology and civilization, while convenience has been greatly enhanced, it has also resulted in a growing volume of waste. As environmental awareness rises, the concept of zero waste has gradually emerged as an ideal solution to the waste problem. This study explores the feasibility of sintering foamed glass using four types of waste materials—waste glass, oyster shells, eggshells, and chalk dust—through high-temperature treatment. The aim is to evaluate whether the foamed glass produced using three different foaming agents can serve as a soundproof green building material and a sustainable lightweight product.

The raw materials were first analyzed for their basic properties, including chemical composition, water-soluble chloride ion content, and pH value. In the experiments, three different sources of calcium carbonate were used as foaming agents, mixed with a fixed proportion of waste glass powder. Sintering conditions (temperatures ranging from 800°C to 950°C, holding time from 10 to 60 minutes) were designed to study the effects of different mix ratios and heat treatment parameters on the density, porosity, water absorption, and cylindrical crushing strength of the resulting foamed glass.

The results indicate that adding calcium carbonate waste can successfully initiate a foaming reaction. Among the materials, eggshells and chalk dust exhibited the best foaming performance. In contrast, oyster shells showed less effective foaming due to their impurities and lower calcium carbonate peak intensity. The foamed glass produced from eggshells and chalk dust demonstrated optimal density, open porosity, and cylindrical crushing strength at 850°C and 900°C. Overall, a foaming agent content of 3 wt% was found to be the most suitable. This study confirms the feasibility of producing foamed glass from waste glass and appropriate calcium carbonate sources, showing promising potential for application in the green building materials market.
