本計畫係針對水泥窯作為資源循環中心進行相關評估，首先蒐集國內外廢棄物作為水泥替代原料之文獻報告與實務資料，瞭解廢棄物對水泥製成與產品性質之潛在影響，釐清實務上面臨的問題與困難。此外，本計畫亦蒐集各國水泥產品品質標準、水泥窯空氣污染排放標準、水泥替代原料相關允收標準等資料，對照歸納相互之間的關聯性，提出未來相關再利用管理之建議。另一方面，針對水泥替代原料前處理中心建置，參考各國類似實務案例，研擬前處理中心之任務目標與模式，並分析國內相關法規對於前處理中心建置申請之行政流程與差異。本計畫除了資料蒐集研析之外，另擇定水洗穩定化灰、焚化再生粒料、氟化鈣污泥、電弧爐煉鋼爐還原碴（石）等4種水泥替代原料進行實廠驗證及產品環境相容性評估，研究結果顯示，水泥廠再利用上述材料對於空氣污染排放及水泥產品性質均無不良影響。本計畫綜合歸納廢棄物作為水泥替代原料在技術上應具有相當的可行性，且是促進資源永續循環的正確方向，實務上可藉由增列公告再利用廢棄物種類、放寬水泥產品氯離子含量標準、簡化申請流程、建立相關業者媒合平台等措施，提升廢棄物作為水泥替代原料之量能。

The purpose of this project was to assess the feasibility of the cement kiln as a resource recycling center. First, this project collected the research papers and practical reports about alternative cement raw materials, and revealed the effects of wastes on the cement manufacturing and cement properties. The problems occurring in cement plants were also explored. Second, this project surveyed the cement specifications, the air pollutant emission limits of cement plants, and the acceptance criteria of alternative raw materials for Taiwan and other countries. A pre-processing facility of alternative cement raw materials was also studied in this project, and the model of pre-processing facility and the regulatory issues were examined. Another important work of this project was to select four wastes as alternative raw materials and to conduct a testing manufacturing. During the cement manufacturing with the four wastes, the exhaust gases and the ambient air quality were monitored, and the resulting cement products were studied using several leaching methods. The results showed that the air pollutant emissions and cement properties were not affected by the wastes reused. This project concluded that a cement kiln is highly feasible to be a resource recycling center, and this can promote the sustainable resources. In practice, listing more Type R wastes, increasing the limits of chloride in cement, simplifying the administrative procedure, and creating a platform for waste exchange can significantly increase the amount of alternative raw materials used in cement plants.
