With the continuous increase in human energy demand and the rapid development of the economy and society, the production of electronic waste, represented by discarded batteries and various inorganic solid wastes, is also continuously increasing. This not only leads to the waste of resources but also causes serious pollution to the environment. Electronic waste has significant resource attributes and is a valuable secondary resource that can be utilized, as well as environmental attributes. With the advancement of the construction of " zero-waste city," the resource recovery process of electronic waste and the issue of secondary pollution are increasingly receiving widespread attention from all sectors of society. Scientific recycling can not only reduce resource waste but also avoid potential threats to the environment and human health. This sub-conference will provide a platform for the exchange of scientific research results and academic discussions, stimulate innovative thinking, and explore the path to ecological and environmental construction in the field of electronic waste recycling, contributing to environmental protection and promoting resource recycling.
