本計畫執行重點包含：(1) 研析國內外推動資源循環零廢棄，環境及經濟效益之成果及蒐集國內外資源循環相關法規，完成橫向整合資源循環相關法規及精進之研究。(2) 研析國內至少五項具代表性之產業資源物，成功之循環經濟商業模式，另完成產業轉型後資源循環零廢棄與轉廢為能關聯性探討及辦理產業有關資源循環零廢棄之轉型策略座談會3場次， 研提短期可行之執行措施。(3)完成辦理國內動靜脈產業座談會3場次，研析減量替代及再使用之創新案例與模式及辦理國內動靜脈產業能資源整合論壇2場次，建置產業合作溝通管道。計畫執行成果如以下說明： 國外資源循環相關法規涵蓋多種面向，包括延長產品壽命、延伸生產者責任、透過政策、計畫、倡議與獎勵措施增加再生物料需求、產品即服務、建置共享平台提供資訊的揭露與再利用管道。鋼鐵業製程有多種副產品如煤焦油、輕油、高爐石、轉爐石、氧化鐵粉、脫硫石及脫硫石著磁料等，經資源化加工後供應化學、營建、土木、電機及民生等產業使用。鋼鐵業的資源整合策略包括多元化資源來源、高效生產、節能減排、循環經濟和研發創新。水泥業透過協同處理技術，以晶圓廠、鋼鐵廠、淨水廠及公共工程等來源的污泥作為替代原物料，減少石灰石、黏土及低鹼砂等天然原物料之耗用、開採與購買。水泥業的營建廢棄物再利用可帶來明顯的減碳效益，歐盟碳定價制度的實施也相對使營建廢棄物經濟效益提升。電子業製程廢棄物含有較多的貴金屬物質，而電子業對於原料品質要求較高，因此提升資源化品質達到電子級是目前電子業廢棄物處理技術的發展方向。電子業實現資源整合的發展策略主要包括供應鏈優化、研發創新、節能減排和循環經濟。這包括提高供應鏈協同作業，降低能源和資源消耗，並採用環保製程。造紙業將回收紙再製為環保產品，此製程的轉換率與水資源循環率皆超過90%，而造紙過程產生的廢液則可作為生質燃料產製蒸汽與電力。造紙業實現資源整合的發展策略主要包括循環經濟、節能減排、原材料多元化和研發創新。包括提倡資源回收和再生紙材的使用，減少廢棄物並提高資源效益。紡織業利用機械法處理技術將廢紡織品重新製成聚酯纖維，另利用化學法處理技術回收聚酯寶特瓶以及混摻其他成分的廢棄聚酯產品，如紡織品、成衣、包裝材料等，轉換為聚酯的主要原料之一再生對苯二甲酸 (rPTA)。紡織業實現資源整合的發展策略主要包括綠色生產、節能減排、原材料多元化和研發創新。包括減少水和能源消耗，採用環保製程，降低環境衝擊。研發新技術和高性能紡織品有助於提高品質，減少環境影響。由五種產業之循環經濟商業模式可發現跨產業合作是共通點，一個產業製程的副產品或廢棄物可能是另一產業的資源，建立有效的跨產業合作機制可促進資源循環利用。國內外鋼鐵業皆積極發展廢熱回收技術，尤其是低溫廢熱回收技術「有機朗肯循環」，另研究指出鋼鐵業製程的轉爐階段的廢熱回收具有最高的技術與經濟潛力。經由情境分析結果，可發現轉廢為能的應用確實可顯著降低碳排放強度，然而若要與淨零排放的趨勢接軌，必須以情境三作為未來發展的方向本計畫以情境三：轉廢為能+綠氫產能情境為基礎，提出短、中、長期發展策略。1.短期（2023-2030年）：在現有的製程下，可增加低溫廢熱回收設備，將能源利用最大化。2.中期（2030-2040年）：2030年前須開始導入綠氫，逐步取代化石燃料，以因應2030年達到碳費高峰所帶來的高生產成本壓力。3.長期（2040-2050年）：2040年時綠氫產能應達到30%以上的能源占比，擴大部署碳捕捉與封存技術，移除少部分化石燃料使用所產生的碳排放。

The implementation priorities of this plan include: (1) studying and analyzing the achievements of promoting zero waste, environmental and economic benefits of resource recycling at home and abroad, collecting relevant laws and regulations of resource recycling at home and abroad, and completing the research on the relevant laws and regulations of horizontal integration of resource recycling. (2) To study and analyze at least five representative industrial resources on the island, successful circular economy business models, and complete the discussion on the correlation between zero waste and waste-to-energy resource recycling after industrial transformation, and handle 3 seminars on the transformation strategy of industry-related resource recycling and zero waste, and study and propose short-term feasible implementation measures. (3) Completed 3 domestic arteriovenous industry symposiums, studied and analyzed innovative cases and models of reduction, substitution and reuse, and handled 2 domestic arteriovenous industry energy resource integration forums, and established industrial cooperation communication channels. The results of the implementation of the plan are described as follows: Foreign regulations related to resource recycling cover a variety of aspects, including extending product life, extending producer responsibility, increasing demand for recycled materials through policies, programs, initiatives and incentives, products as a service, and establishing a shared platform to provide information disclosure and reuse channels. There are a variety of by-products in the steel industry, such as coal tar, light oil, blast furnace stone, converter stone, iron oxide powder, desulfurization stone and desulfurization stone magnetic material, etc., which are supplied to chemical, construction, civil, electrical and livelihood industries after resource processing. The steel industry's resource integration strategy includes diversification of resource sources, efficient production, energy conservation and emission reduction, circular economy and R＆D innovation. The cement industry uses sludge from wafer fabs, steel plants, water purification plants and public works as alternative raw materials to reduce the consumption, mining and purchase of natural raw materials such as limestone, clay and low alkali sand through co-processing technology. The reuse of construction waste in the cement industry can bring significant carbon reduction benefits, and the implementation of the EU carbon pricing system will also improve the economic benefits of construction waste. The process waste of the electronics industry contains more precious metal substances, and the electronics industry has high requirements for the quality of raw materials, so improving the quality of resources to reach the electronic grade is the current development direction of the waste treatment technology of the electronics industry. The development strategy of the electronics industry to achieve resource integration mainly includes supply chain optimization, R＆D innovation, energy conservation and emission reduction, and circular economy. This includes improving supply chain collaboration, reducing energy and resource consumption, and adopting environmentally friendly processes. The paper industry recycles recycled paper into environmentally friendly products, with a conversion rate and water recycling rate of more than 90%, and the waste liquid from the papermaking process can be used as biomass fuel to produce steam and electricity. The development strategy of the paper industry to achieve resource integration mainly includes circular economy, energy conservation and emission reduction, raw material diversification and R&D innovation. This includes promoting resource recycling and the use of recycled paper to reduce waste and improve resource efficiency. The textile industry uses mechanical processing technology to reconvert waste textiles into polyester fibers, and uses chemical treatment technology to recycle polyester PET bottles and waste polyester products mixed with other ingredients, such as textiles, garments, packaging materials, etc., and convert them into recycled terephthalic acid (rPTA), one of the main raw materials of polyester. The development strategy of the textile industry to achieve resource integration mainly includes green production, energy conservation and emission reduction, raw material diversification and R&D innovation. This includes reducing water and energy consumption, adopting environmentally friendly manufacturing processes, and reducing environmental impact. R&D of new technologies and high-performance textiles can help improve quality and reduce environmental impact. From the circular economy business model of the five industries, it can be found that cross-industry cooperation is the common point, the by-products or waste of one industrial process may be the resources of another industry, and the establishment of an effective cross-industry cooperation mechanism can promote resource recycling. The domestic and international steel industries are actively developing waste heat recovery technology, especially the low-temperature waste heat recovery technology "Organic Rankine Cycle", and research has pointed out that waste heat recovery in the converter stage of the steel industry has the highest technical and economic potential. However, in order to align with the trend of net-zero emissions, it is necessary to take Scenario 3 as the direction of future development. 1. Short-term (2023-2030): Under the existing manufacturing process, low-temperature waste heat recovery equipment can be added to maximize energy utilization. 2. Medium-term (2030-2040): Green hydrogen must be introduced by 2030 to gradually replace fossil fuels to cope with the high production cost pressure caused by the peak of carbon bills in 2030. 3. Long-term (2040-2050): By 2040, green hydrogen production capacity should reach more than 30% of the energy share, expand the deployment of carbon capture and storage technology, and remove a small amount of carbon emissions from fossil fuel use.
