    Abstract: 工業產品高度量產時,伴隨產生大量廢棄物,若處置不當,將嚴重影響生活環境與企業發展。另一方面,天然砂石資源開採受到限制與供需不平衡,導致砂石價格不斷上漲。故將工業廢棄物資源化再利用並減少天然資源開發成為重要課題,部分工業廢棄物可製成再生粒料,用以取代天然粒料,因此擬定工業廢棄物應用推廣策略,可有效處理廢棄物,亦能紓緩砂石料源之不足。 本研究調查砂石供需與水泥銷售資料,以移動平均法預測未來五年全國、公共與民間工程之砂石需求。針對營建工程進行粒料需求調查與預測,包括道路工程基底層、CLSM、無筋混凝土、工程填地料及地質改良材料等用途,結果可用於應用推廣分析。目前資源化技術已相當成熟,亦有研究成果顯示再生粒料之可用性,但再生利用現處於發展階段,施工規範不健全與使用者信心不足,導致市場應用受到限制。研究中選定三種工業廢棄物(鈦鐵礦氯化爐碴、煉鋼爐碴與廢鑄砂之混合砂、焚化爐飛灰)進行應用策略規劃,運用SWOT分析評估各個案,擬定最佳應用推廣策略,尋求應用推廣方向,供資源化企業參考。依結果顯示,再生粒料取得環保性制度認證,可提高產品品質正面形象,為工業廢棄物再利用應用推廣重點。 When industrial products go mass production, it also brings a large amount of wastes need to be disposed of. If the recycling measure is insufficient, both the living environment and enterprise development will be badly affected. On the other hand, due to the limitation in mining natural aggregates, the demand in aggregates remains high and the cost keeps increasing. Therefore, the use of industrial wastes as a replacement for natural aggregates has became a critical issue. Many industrial wastes can be reprocessed as recycled aggregate, in order to replace natural aggregate. This will help to ease up the lacking in aggregate supplies. This research is to examine the supply and demand of aggregates for the construction industry. The moving average approach was used to predict the demand in aggregates for the next 5 years. The demand in aggregates was analyzed individually for various applications, including road base aggregate, CLSM, plain concrete, the engineering fills, and ground improvement material. The results can be used as an analyzing basis. Nowadays the recycling techniques has greatly improved, many studies have demonstrated the suitability of recycled aggregates in engineering applications. Although the recycling skills have progressed a great deal, the lack of construction specifications and of confidence by potential users has limited the market development for waste applications. Three industrial wastes (TCS, EAF slag, cast-iron scrap, and incinerator fly ash) were selected to conduct a strategic planning. SWOT technique was used to analyze and evaluate the 3 cases to come up with best strategy to promote the use waste materials as aggregates. The results show that an environmental certificate will help in promoting the application of wastes in a positive way.
