Resource recycling is a pivotal measure for advancing environmental protection and fostering sustainable social development. East Asian countries and regions share geographical proximity and confront analogous challenges in resource utilization and environmental conservation. To facilitate the timely exchange of insights and propel resource recycling initiatives, collaborative efforts among pertinent organizations in these areas gave rise to the "International Symposium on East Asia Resource Recycling Technology" in 1991. This biennial conference rotates among the East Asian countries and regions and was successfully convened 16 times. The 17th International Symposium on East Asia Resource Recycling Technology (EARTH 2024) was slated for November 1-4, 2024, in Changsha, China. Organized by the Nonferrous Metal Society of China, Central South University, and other relevant entities, the symposium extends warm invitations to friends from diverse backgrounds to participate in this significant event in Changsha. 资源再生利用是实现环境保护和社会可持续发展的重要举措。中国大陆、日本、韩国、中国台湾和泰国等国家和东亚地区，地域相连、情况相近，在资源利用、环境保护等方面有许多共性问题。为了及时交流经验、推动资源的再生利用，上述国家和地区的相关组织联合发起，从1991年开始，每隔两年轮流在四地召开“东亚资源再生技术国际会议”，至今已成功召开了16次。第17届东亚资源再生技术国际会议(简称EARTH 2024)将于2024年11月1日-4日在中国长沙召开，由中国有色金属学会、中南大学等有关单位主办，热忱欢迎各界朋友莅临长沙，共襄盛会。
