無機資源循環材料技術研發與管理計畫

中文摘要 隨著淨零碳排已成為各國重要政策,國發會已於111年3月公布淨零排放路徑圖及淨零轉型12項關鍵戰略,作為各行各業從減碳、低碳邁向淨零永續共同努力的方向。其中,與廢棄物相關之「資源循環零廢棄」,亦被納為淨零轉型關鍵戰略之一,主要方法將透過「廢棄資源物質能資源化」、「強化資源永續循環利用」及「鏈結上中下游產業形成資源循環產鏈」等,推動廢棄物面向之淨零措施。 我國事業廢棄物中以無機廢棄物產生量最大且多為製程末端剩餘之碴(渣)類或污泥類物質,易含重金屬,部分尚有具膨脹性等不穩定成分,惟現行國內主要安定化技術之能耗高;另無機廢棄物去化現況又以預拌混凝土、控制性低強度回填材料(CLSM)等工程材料用途為主,其均需添加高碳排材料水泥,未來推動無機廢棄物循環利用,宜朝向可克服前述成分特性問題及降低碳排放量之技術發展。 緣此,本計畫運用「無機聚合」等低碳排技術,以鋼鐵業產生之「還原碴」、轉廢為能燃料混燒後之「混燒灰渣」及砂石碎解洗選場廢水處理設施產出「泥餅」3項具去化問題之無機資源物作為原料進行循環材料與應用產品開發。 本計畫成果重點包括: 1. 掌握3項無機資源物運作現況及主要資源化技術,彙整遭遇困難及提出技術面因應策略。 2. 採樣分析3項無機資源物之成分特性及環境安全性,透過實驗室以前述原料開發無機循環材料配比及試體試作,建立最佳摻配比,透過檢測分析掌握無機循環材料特性、限制及未來可評估開發之應用方向。 3. 於實驗室以無機循環材料優先產製4項開發之應用產品,包含:非構造物用混凝土、CLSM、人造粒料及高壓地磚,透過產品品質檢測掌握其應用之可行性,以及蒐集相關原料使用、價格、製程設備及品管需求、碳排係數等資訊,評估4項產品之應用潛勢及效益。 4. 媒合3項無機資源物產源事業及再利用機構,輔導提出再利用試驗計畫申請,完成廢棄物特性檢測、允收標準訂定、運輸路線及方式規劃、製程運作程序、產品品質標準訂定、衍生廢棄物處理及產品銷售規劃等,逐步落實技術實廠化推動。 5. 配合添加穩定液之皂土去化需求,辦理採樣、成分特性分析,評估運用無機聚合技術開發之可行性。

Research and Management of Inorganic Recycling Material

英文摘要 With net zero carbon emissions becoming a crucial policy for countries worldwide, National Development Council (NDC) announced the Net Zero Emissions Roadmap and 12 key strategies in March 2022. These strategies serve as a collective direction for various sectors to shift from carbon reduction and low-carbon practices towards sustainable net-zero goals. Among these strategies, "zero waste in resource circulation" related to waste management has been recognized as one of the pivotal strategies. The primary approach involves "waste-to-energy conversion," "enhancing sustainable resource circulation," and "connecting upstream, midstream, and downstream industries to create a resource supply chain." These initiatives aim to promote waste management measures aligned with the net-zero emissions objectives. Hence, this project utilizes low-carbon emission technologies such as "geopolymeric technology " to develop recycling materials and application products using three inorganic resources with disposal issues: "EAF reduction slag" generated from the steel industry, "co-fired ash" from waste-to-energy incineration, and "washing aggregate sludge" from the wastewater treatment facility of sand and gravel fragmentation and washing plant. Key points of this project include: 1. Gain an understanding of the current operational status and major recycling technologies for three inorganic resources, summarize the challenges faced, and propose technical strategies. 2. Sample and analyze the composition characteristics and environmental safety of three inorganic resources. Develop material compositions and conduct specimen trials in the laboratory by using these resources. Establish the optimal ratios and, through testing and analysis, grasp the characteristics, limitations, and potential application for these materials. 3. Produce four priority products by using inorganic recycling materials in the laboratory, including non-structural concrete, controlled low-strength material (CLSM), artificial aggregates, and Compressed concrete paving units. Determine the feasibility of their applications through product quality testing, and gather information on related raw material usage, pricing, process equipment, quality control requirements, carbon footprint, etc. Evaluate the potential and benefits of the four products. 4. Facilitate collaboration between three inorganic resource source businesses and reuse organizations, providing guidance on applying for trial plans. Complete waste characterization, establishment of acceptance standards, planning of transportation routes and methods, operational procedures, product quality standards, handling of derived waste, and product sales planning. Gradually implement the promotion of technology in actual production. 5. In response to the demand for the removal of bentonite with stabilizing agents, conduct sampling, analyze component characteristics, and assess the feasibility of using inorganic geopolymeric technology.
