營建廢棄物多屬安定且無害之資源，此類資源是世界各國推動資源循環再利用之主要標的，而建立有益的廢棄物管理是國家推動循環經濟政策之基礎。為了提升營建資源再利用之效益並建議合適策略，本計畫除了回顧國內外相關政策與規範外，亦根據既有系統及文獻資料，逐一盤點營建工程使用之資源、相關廢棄物產生量、再利用規範及含石綿廢棄物處理等資訊。在盤查政府公開資訊後發現，109年營建工程約莫消耗10,185萬噸混凝土及678萬噸金屬製品，同年產出營建廢棄物約205萬噸與7,564萬噸營建剩餘土石方；110年1月~8月，營建工程約莫消耗6,634萬噸混凝土，金屬製品尚未公告。除了資源與廢棄物盤查外，本年度其他工作成果摘要如下： 1.調查裝潢修繕工程常見板材之使用及處理現況，透過訪談與座談，深入分析裝潢修繕廢棄物流向與遭遇問題，並檢討矽酸鈣板及石膏板使用及廢棄處理情形。配合現況與需求，提出規劃裝潢修繕廢棄物申報專區、落實證明文件、檢討再利用管理規則等策略。 2.彙整無機再生粒料於道路工程與次要結構混凝土工程應用之品質標準，並初步研擬營建廢棄物於次要結構混凝土使用之品質建議，並提供自主檢核與品質規格表範例。 3.彙整國內外循環經濟認證系統、評估方法以及指標，並蒐集既有工程案例約20例，主要循環營建手法包含建材銀行、建材護照、模組化設計、以租代買、綠色能源及共享空間等。 4.完成含石綿廢棄物現況及流向調查，並檢討既有廢石綿處理機構之量能與方式。完成調查國內潛在以熱處理方式處理含石綿廢棄物之處理機構，研析其處理含石綿廢棄物之處理量、設備經費成本及相關管理規定，並提出石綿廢棄物處理建議等。 5.辦理三場專家諮詢會議，評估營建廢棄物管理策略，並檢討建立營建產業聯盟之策略。

Most construction and demolition wastes are stable and harmless substances, and these are also main recycling and reusing resources the whole world over. Therefore, establishing beneficial management and reuse strategies for construction and demolition waste had become significant toward the circular economy over the past few years. To improve the efficiency of resource circulation from construction and demolition waste, and assist to establish management strategies for that, the objective of this project was not only to review and analyze domestic and international regulations and strategies, but also to take an inventory of natural resources quantity for construction, relevant wastes generation situation, relevant reuse specifications, and asbestos-containing wastes treatment rules, and so on. According to the related official statistical data of resources and industrial wastes, among the primary utilized resources for construction in 2020, the metal products, including structural steel, reinforcement, etc., were used almost 6.89 million tons and concrete products, including ready-mixed concrete, concrete pipe and brick, etc., were used over 100 million tons. On the other hand, the construction wastes were generated around 2.05 million tons and surplus soils were generated even over 75.6 million tons after construction and demolition. In addition to inventory construction resources and wastes, the other major results of this project were as follows： 1. Investigated types, and treatment ways of wastes after interior renovation and upholstery, especially board materials, like calcium silicate and gypsum board. This project positively analyzed these encountered difficulties for reusing, recycling, and disposal of these wastes, and then discussed and suggested proper management strategies such as developing a unique declaration information system, certainly carrying source certification documents as well as reviewing current regulation of construction industrial waste. 2. Collected and analyzed each quality standard of utilizing inorganic recycled aggregates for road construction and products, and then, developed a secondary structural concrete products quality standard draft and self-checklists for reusing and recycling construction and demolition wastes. 3. Collected and reviewed domestic and international researches, indicators, and certification systems of the circular economy. Besides, this project also summarized construction circulation design strategies from 20 real construction cases, including a material bank, material passport system, reassembly design, green energy, renting as well as functional shared spaces. 4. Investigated the current situation of treatment or disposal of asbestos-containing wastes. Furthermore, this project also reviewed and evaluated the possibility, cost, and related regulations of the final disposal of asbestos-containing wastes by heat treatment. Lastly, the appropriate disposal suggestions were proposed. 5. Held 3 expert meetings to confirm the probable management benefits and suggestions for construction and demolition waste, and then evaluated the strategies for the construction relent industry alliance.
