Because of incomplete recycling resource management and technology development, inorganic sludge and slag has been misused in Taiwan. The recycling of inorganic sludge and slag is a pressing crisis. Resource materials with a sustainable use value are misplaced and have a significant impact on society and the environment, which greatly reduces industrial competitiveness. To solve the dilemma of EAF oxidizing slag recycled from the steel-making process, it is important to find solutions to improve the stability of EAF oxidizing slags based on the innovative thinking of the circular economy. We can improve the value of recycling resources and solve the contradiction between economic development and environmental impact. The project team intends to investigate the development and application of reclaiming EAF oxidizing slags blended with fire-retardant materials, which will integrate R&D work from four different aspects. First, a verification mechanism is carried out to establish stainless steel furnace materials. Suppliers must be assisted in conducting quality management for EAF oxidizing slags to ensure the quality of the materials provided. Next, high-value building materials must be developed using slag stabilization technology, and fire-retardant tests must be conducted on the recycled building materials. A comprehensive evaluation and verification of the recycled building materials must be undertaken, and high-value green building materials must be produced with fire-retardant and sound-proofing characteristics. Integration with national standards and regulations can drive the market integration of high-value building materials and the industrial chain. On the other hand, the applicability of existing regulations to facilitate the legal use of EAF oxidizing slags will be explored.
由于资源回收管理及技术发展不完整，台湾地区无机污泥及炉渣被不当利用。无机污泥及炉渣的回收是一项紧迫危机。具有可持续利用价值的资源材料被错置，对社会及环境产生重大影响，大幅降低产业竞争力。为解决炼钢过程中电弧炉氧化渣回收的困境，基于循环经济的创新思维寻找提高电弧炉氧化渣稳定性的解决方案很重要。我们可以提高回收资源的价值，解决经济发展与环境影响之间的矛盾。项目团队打算研究回收与阻燃材料混合的电弧炉氧化渣的开发及应用，这将从四个不同方面整合研发工作。首先，开展验证机制以建立不锈钢炉材料。必须协助供应商对电弧炉氧化渣进行质量管理，以确保所提供材料的质量。其次，必须利用炉渣稳定化技术开发高价值建筑材料，并对回收建筑材料进行阻燃测试。必须对回收建筑材料进行全面评估和验证，并生产具有阻燃和隔音特性的高价值绿色建筑材料。与国家标准和法规接轨可推动高价值建筑材料及产业链的市场整合。另一方面，将探索现有法规的适用性，以促进电弧炉氧化渣的合法利用。
