摘要

為因應提倡綠色能源，目前台灣大力推動太陽能產業發展，太陽能板製造量將大幅增加，而太陽能板之生命週期約為15年至25年，故可推估未來20年間將持續有大量廢棄物產生，因此，為降低環境負荷、有效的利用資源，將廢棄物資材化是未來處理的趨勢。本研究探討利用製坯燒結技術，將太陽能板廢玻璃取代黏土燒結製磚，可資源化再利用為有價值的營建工程材料。本研究以燒結溫度介於700－1000℃對試體進行燒結處理，加熱速率為10℃/min，持溫6小時。燒結後之燒結體進行各種測試，包括燒失量、體積收縮率、體比重、孔隙率和抗壓強度等。實驗結果顯示太陽能板廢玻璃經由毒性特性溶出程序試驗，重金屬溶出量皆低於法規標準值，故具有再利用資源化之潛力。燒結體隨著太陽能板廢玻璃添加量的提高導致燒結體吸水率的下降和抗壓強度的提升。當燒結溫度為1000℃時，太陽能板廢玻璃取代量為30%之燒結體的吸水率和抗壓強度均符合中國國家標準（CNS）所規範的第一級磚之標準。當燒結溫度為1000℃時，太陽能板廢玻璃取代量為40%之吸水率低於10%，而抗壓強度高達1381kgf／cm^2，此結果顯示，太陽能板廢玻璃取代部分黏土可燒製強度較高之紅磚，故太陽能板廢玻璃具有資材化的潛力。

Waste compromises environmental preservation as well human health in many countries. Recycling is an alternative that sometimes represents the only economical activity for a significant population in the big cities. The recycling waste glass of solar panels, therefore, is an important issue to be discussed. This study deals with the effect of solar panel waste glass on fired clay bricks. Brick samples were heated to temperatures which varied from 700 to 1000℃ for 6 hrs, with a heating rate of 10℃/min. The material properties of the resultant material then determined, including speciation variation, loss on ignition, shrinkage, bulk density, 24-hour absorption rate and compressive strength. Toxicity Characteristic Leaching Procedure tests were also conducted. The results indicate that the heavy metal concentrations in the leachates met the current regulatory thresholds. Increasing the amount of solar panel waste glass resulted in a decrease in the water absorption rate and an increase in the compressive strength of the solar panel waste glass bricks. The 24h-absorption rate and compressive strength of the solar panel waste glass brick made from samples containing 30% solar panel waste glass sintered at 1000℃ all met the Chinese National Standard (CNS) building requirements for 1st class brick. The addition of solar panel waste glass to the mixture reduced the degree of firing shrinkage. This indicates that solar panel waste glass is indeed suitable for the partial replacement of clay in bricks.
