本計畫蒐集日本、美國、荷蘭、澳洲與英國等國家之離場污染土壤再利用方式與技術。除了處理技術與製程管理，本計畫亦蒐集國外污染土壤及其他廢棄物再製產品中污染物含量限制與產品用途之相關法令規範。本計畫採集之污染土壤再製產品，經試驗與分析後，均符合土壤污染管制標準及有害事業廢棄物認定標準。在水泥產業中，重金屬鉻之溶出行為較為顯著。在紅磚產業，重金屬砷、銅、鉛、鎘等之溶出行為較為明顯。在土石清洗產業，需要測試不同酸性清洗劑與其濃度、酸性清洗槽固液接觸時間等，找出不同重金屬最佳去除操作條件。本計畫參考現行廢棄物再利用管制機制，除事業廢棄物來源、再利用用途、再利用機構應具備資格、運作管理等，並增加製造程序、檢測規定、流向管理及申報等作業準則。在污染土壤有機污染物方面，目前已通過申請為熱處理技術，可參考「事業廢棄物貯存清除處理方法及設施標準」採操作溫度管制，以確保有機污染物去除效率達99%以上。在土壤重金屬污染方面，主要參考歐盟已發展成熟的制度架構，再與國內現行的管理措施及公告檢驗方法加以比對檢討，以融合出適合我國污染土壤離場再製產品的評估流程。短中長期執行方向，短期：研析包括國內外土壤離場再製產品產業之技術清單、製程技術規範與作業準則、產品生命週期及產品應用之環境衝擊，及產品相關檢測方法使用程序與評估標準；中期：研析包括污染土壤離場再製產品品質標準值、產品使用規範，及產品驗證管理制度；長期：研析相關法規規範修正之方向及內容、研析污染土壤離場再製產品履歷及標章策略推動之可行性，及推廣並提升污染土壤再製產品之使用率。

This project collected information regarding the technologies of the reuse and recycle of the treated contaminated soils in Japan, the United States, Nederland, Australia, and the United Kingdom. Besides the technologies, the information regarding the regulations about the limitations of the contaminants and the associated leaching characteristics of the remanufactured product using contaminated soils was also included. In the cement manufacturing, the leaching of chromium was found to be significant. In the red brick industry, the leaching of the arsenic, copper, lead, and cadmium are of concern. In the soil washing method, it was found that various solutions with different concentration and contact time for different heavy metals was needed for test and verification. With the consideration of the current waste recycling mechanism, manufacturing process, quality assurance verification, product tracking, and reporting are recommended as the operation standards in addition to the source tracking of the industrial wastes used, recycling use, the certificate of the recycling manufacturer, and operation records. For the organic contaminants, the current certified method is thermal destruction. It would be necessary to set the lower limit of the operation temperature in order to meet the standard of 99% removal. For heavy metal contaminants, the analytical methods are suggested to follow the current standard methods with the consideration of the regulation structure of the Europe Union. With respect to the short, middle, and long terms suggestions for the future studies, the short term suggestions focus on the studies of onsite and offsite remediation technology list for soil pollution, regulations of the manufacturing procedures of the concerned industries, product use and its environmental impacts, etc. The middle term suggestions include establishing product quality standards, remanufactured product use guidance, and verification and regulation of the product quality, etc. The long term suggestions include the revision of the related laws and regulations, remanufactured product history, the feasibility of Safety Mark of Recycled Material, and the strategy of widening remanufactured product use.
