我國資源有限，隨著政策法規對於相關廢棄物處理與環境標準提升，國內高溫產業與熱處理機構產量龐大的無機廢棄物如集塵灰與爐渣，急需進一步開發其資源化技術，使環境成本得以降低。金屬冶煉產業於金屬煉製時，伴隨產生大量煉製產業廢棄物，例如：電弧爐煉鋼廠之還原碴與煉鋁廠之鋁渣，年產量分別為40萬噸與1萬噸以上；而玻璃產業，進行生料高溫熔解製造玻璃膏的製程，單一家玻璃業每年於袋式集塵設備收集650噸玻璃集塵灰，由於含重金屬需掩埋處理。熱處理機構方面，都市廢棄物以焚化為處理主流，每年產生20萬噸的飛灰，因重金屬含量高，歸類為有害事業廢棄物，亦僅能固化掩埋，產生之成本高昂。本計畫主要目標為開發上述所列高溫製程生產的廢棄物之資源化應用技術，使未來這些廢棄物得以去化，並降低堆置與掩埋之環境負荷與成本。本報告重點摘錄：1.矽鋁廢棄物部分完成2家煉鋼廠的還原碴取樣5件次，並完成鋁渣取樣6件次，其TCLP、硫化物與氯鹽分析皆符合法規標準，建立鋁渣與還原碴初步量體盤點與特性資料，將之進行粒徑分級與熱處理後，初步應用至鹼激發膠結材料配方，於特定條件下最佳試體抗壓強度可達400kgf/cm2以上，廢棄物含量於膠結材料占比可達30%以上，並完成小型水工試體之水中磨損率測試，完成其做為水工載具應用評估。 2.焚化飛灰處理方面，盤點垃圾廠焚化飛灰及具熱改質潛力廢棄物數量，並彙整具改質助熔潛力資源物至少包括玻璃及其製品類資源物、鋁系渣類資源物、含鐵氧化物資源物歷年產出量及處理與再利用情形，並進行基本特性分析，蒐集國際上經過熱處理程序後之焚化飛灰再利用現況、市場價值與技術研發近況；技術方面，節能燒結配方設計與12件次試驗與分析，已獲得符合4項環境標準、密度及吸水率標準之配方及燒製條件。 3.玻璃集塵灰方面，完成國內6大玻璃煉製廠集塵灰可回收之資源種類、數量與市場規模資料盤點，完成建築平板玻璃與色板玻璃等各種玻璃集塵灰採樣12件次，建立玻璃集塵灰7項成分分析與檢測方法，包括純度、無機鹽、重金屬、結晶水、平均粒徑、核磁共振與紅外線光譜，蒐集與探討國內外玻璃集塵灰與硫酸鈉相關純化技術與專利資料後，整合與測試溶解、化學去除、連續離心、低溫結晶與乾燥粉碎等純化單元，完成玻璃集塵灰濕法回收流程設計開發，進行每次10公斤共12批玻璃集塵灰回收製程測試，測試結果其中10批回收芒硝平均純度98%、回收率74%，回收芒硝成分與物性分析經第三方單位驗證通過，最後進行回收芒硝原料試熔測試與建築平板玻璃製程驗證，回用回收芒硝產製出平板玻璃外觀及規格符合產品需求，驗證玻璃集塵灰作為再生料循環再利用玻璃製程可行性。

摘要	Our country has limited resources. With the improvement of policies and regulations on the disposal of related waste and environmental standards, the domestic high-temperature industries and heat treatment facilities produce a significant amount of inorganic waste such as dust and slag. There is an urgent need to further develop resource utilization technologies for these waste materials to reduce environmental costs. In the metal smelting industry, a substantial amount of waste is generated during metal refining, such as reducible slag from electric arc steel plants and aluminum dross from aluminum refining plants, with annual production quantities exceeding 400,000 tons and 10,000 tons, respectively. In the glass industry, the process of high-temperature melting for glass production generates large amounts of glass dust that is collected using baghouse dust collectors. Due to the presence of heavy metals, this waste needs to be disposed of in landfills. Regarding heat treatment facilities, municipal solid waste is predominantly treated through incineration, producing 200,000 tons of fly ash annually. Due to its high heavy metal content, it is classified as hazardous industrial waste and can only be solidified and buried, resulting in high disposal costs. The main goal of this project is to develop resource utilization technologies for the waste produced from the aforementioned high-temperature processes. The aim is to effectively eliminate these wastes and reduce the environmental burden and costs associated with disposal and landfilling. This report highlights the following points： 1.For silicon-aluminum waste, sampling was conducted from the reducible slag of two steel plants five times and from aluminum dross six times. The analysis of TCLP, sulfides, and chlorides met regulatory standards. A preliminary inventory of aluminum dross and reducing slag was established, and after particle size classification and heat treatment, these materials were applied to the formula of alkali-activated cementitious materials. Under certain conditions, the optimal compressive strength of the test body can reach more than 400kgf/cm2, and the waste materials content can account for more than 30% of the cementitious material. The analysis of hydraulic concrete surface wear has been complete to evaluate its feasibility as a hydraulic structure application. 2.As for the incineration fly ash treatment, the quantity of the fly ash and the potential waste materials that are of thermal modification was conducted. The information regarding the annual production, treatment, and re-use of the potential waste materials including glass, aluminum dross, and steel slags were collected, and their basic characteristic was also analyzed. The information of the current thermal treatment technologies, marketing, and technology development of the incineration fly ash was collected as well. In technological issue, the energy saving composition design and the 12 tests of the sintering process were carried out and the 4 environmental standards, the density standard, and water content limit were achieved. 3. In terms of glass fly ash: Completed an inventory of recyclable resources from six major glass manufacturing factories in Taiwan, including the resources types, quantities, and market size in the glass fly ash. Completed 12 samples of various fly ash collections from architectural flat glass and tinted flat glass processes. Through characteristic analysis, establish 7 analysis and testing methods for glass fly ash, including purity, metal oxides (XRF), heavy metals (ICP), crystal water, particle size, NMR, and FT-IR spectroscopy. After collecting and discussing the purification technologies and scientific references related to glass fly ash and sodium sulfate production, we integrated, constructed, and tested different purification units such as dissolution filtration, chemical precipitation, centrifugation, crystallization, drying, and crushing. We completed the design and development of the wet chemical recovery process for glass fly ash and successfully tested the glass fly ash recovery process 12 times with 10 kg each time. The testing results showed that recyclable sodium sulfate products from fly ash had an average 98% purity and 74% yield. Through SGS inspection and analysis, it was verified that the composition and physical properties of the recyclable sodium sulfate products achieved target specifications. Finally, the recyclable sodium sulfate passed the glass raw material dissolution test and passed the reusing verification of the architectural flat glass process. The appearance and specifications of flat glass using recycled sodium sulfate comply with product requirements. Proves the feasibility of glass fly ash being recycled as a raw material in the glass manufacturing process.
