The government has already managed data related to some domestic metals, chemicals, and waste resources. However, these data are currently managed by different government agencies, leading to dispersed information and inconsistent formats. Therefore, this project focuses on taking an inventory of the existing government management platforms and, based on the results of industry visits, establishing an integrated metal/chemical and recycling industry network platform system. The project also includes research on international recycling indicators and carbon emissions analysis. By connecting upstream and downstream stakeholders to provide information on resource flow and product reuse tracking in key industry chains, a resource recycling chain management platform will be established.
The work for this fiscal year includes four major tasks, which are planned to be carried out from March 30th to November 30th. The current progress is at 100% and aligns with the planned checkpoints. The project has four main components: (1) Taking an inventory of the government's various departmental resource recycling management information platforms and consolidating the current metal/chemical management framework and baseline data sources. This includes identifying three major breakpoints in information flow: differences in data items between departments, lack of clear information on resource flow during raw material use and manufacturing stages, and data and flow gaps during waste and reuse stages. Strategies are formulated to address these breakpoints. Site visits to 15 upstream and downstream companies in the recycling chain were conducted to clarify actual material flow, capacity, industry purification technology, and the state of recycled products. Quality conservation law inspection and estimation data accuracy were also introduced, and on-site visits verified the feasibility of the data estimation method in this project. However, for data accuracy and completeness, real data obtained through a tracking system can be validated in the future. In addition, to establish a predictive model for industry development trends as a reference for metal/chemical management and promotion, 55 economic statistical indicators from the Ministry of Economic Affairs' statistics department were collected and analyzed. These indicators were used as influencing factors for the statistical analysis of industry development trends, and modeling was conducted based on the collected data to predict the usage and disposal of five major industries in 2025, 2030, and 2050, focusing on basic metal manufacturing (large usage, large disposal). (2) Planning the database structure and operational mode of the metal/chemical related platform. The platform's structure is divided into three categories: data collection (database establishment, data connection), data analysis (material circulation flow, waste production capacity trend), and service functions (material management, visualization display, information inquiry, etc.). Execution planning is based on the feasibility of future planning and data connection. The development of the metal/chemical traceability system framework in this year's project focuses on domestic recycling management, with a focus on outside-the-factory recycling. Different materials, metals, and chemicals may have different considerations and approaches in digital traceability planning, but the goal is to comprehensively record the product life cycle, enhance traceability, and promote resource recycling. In the future, the power of a public association can be used to promote consensus among industry players on digital product traceability, reducing entry barriers. (3) Gathering data from the European Union's Circular Economy Action Plan and Taiwan's Resource Recycling Analysis System, compiling eight reference indicators, and using the EU's proposed specific waste recovery rates and circular material usage rate as reference data for domestic indicator formulation. Finally, three methods for estimating carbon reduction benefits—Process-Based Analysis (PB), Input-Output Analysis (IO), and Composite Analysis—are analyzed. The primary method used is Process-Based Analysis (PB), which was used to analyze the carbon emission differences for two chemical industries, isopropanol and sulfuric acid, as well as aluminum and nickel. Carbon reduction benefits were calculated at 16,400 tons/CO2e for isopropanol and 1,190 tons/CO2e for sulfuric acid. (4) Organizing three expert consultation meetings on metal and chemical recycling information-related issues, covering topics such as the methodology and framework for establishing metal/chemical recycling baseline data, methods for estimating carbon reduction benefits in chemical recycling, and the process framework for metal/chemical resource management traceability. A total of 45 participants and seven experts attended these meetings. Additionally, the project published an article in the October issue of "Industrial Materials Magazine" (Issue 442), discussing the purification technology and promotion status of chemicals (concentrated sulfuric acid, isopropanol) and metals (aluminum, nickel) industries and providing recommendations for the future.
