The research project was progressed as planned. In addition to direct aqueous carbonation, innovative indirect carbonation with circular concept was developed. The circular indirect carbonation of coal fly ash was investigated. The detailed mechanisms, including innovative electrochemical technology, bipolar membrane electrodialysis, were determined, and the comprehensive assessment based on several scenarios of energy supply was conducted. The results were successfully published as research paper in Journal of Environmental Chemical Engineering, which is reputable and in Q1 ranking (IF: 7.968). In addition, the CO2 emissions reduction potential by mineral carbonation of alkaline wastes and byproducts using Taiwan as a case was evaluated. The promising candidate materials and industries wastes were identified, and the significant factors affected the development strategy were pointed out. This study was published as review paper in Environmental Chemistry Letters, which is reputable, and not only in Q1 ranking but also top 5% journals (IF: 13.615).In addition, in this fiscal year, I attended two international conferences in the form of oral presentations. One is The 16th International Symposium on East Asian Resources Recycling Technology (EARTH 2022), hold in Tainan, Taiwan. Another one is International Conference on Green Energy and Applications (ICGEA 2023), hold in Singapore. In ICGEA 2023, I received the best presentation award.

研究项目按计划进行。除了直接水碳化外，还开发了具有循环概念的创新间接碳化。对燃煤飞灰的循环间接碳化进行了研究。确定了包括创新的电化学技术、双极膜电渗析在内的具体机理，并基于几种能源供应方案进行了综合评估。研究成果作为科研论文发表在《环境化学工程杂志》上，口碑良好，排名第一位(IF：7.968)。此外，以台湾地区为例，对碱废及副产品的矿物碳化二氧化碳减排潜力进行评估。确定了具有发展前景的候选材料和工业废弃物，指出了影响发展战略的重要因素。这项研究发表在《环境化学快报》上的综述论文，声誉良好，不仅在Q1排名中，而且在前5%的期刊中(IF：13.615)。此外，在本财年，我还参加了两次国际会议，以口头报告的形式。一是在台湾台南举行的第十六届东亚资源回收利用技术国际研讨会(地球2022)。另一个是在新加坡举行的绿色能源及应用国际会议(ICGEA 2023)。在ICGEA 2023年，我获得了最佳演示奖。
