The symposium scope extends from process fundamentals to operational practices, and also includes the important aspect of environmental issues. At the operations level, comprehensive reviews of the major applications of both metals are outlined. Emphasis will be placed on recent commercial developments with less energy intensive technologies which are in harmony with environmental conservation. At the research level, the emphasis is placed on the better understanding of existing technologies and the development of new processing concepts. Environmental concerns, associated with the processing of both metals, are considered along with acceptable treatment and handling of by-products, wastes and bleed streams by the industry. A highlight of the conference will be a series of plenary lectures by industry leaders. Various social events are scheduled, and these will allow informal discussions and networking among the delegates.

2020 TMS Annual Meeting & Exhibition: Recycling of Secondary, Byproduct Materials and Energy: Organized by Mingming Zhang; John Howarter; Elsa Olivetti; Alan Luo; Adam Powell; Ziqi Sun

There has been a significant mismatch between the technical needs for responsible treatment of secondary, byproduct materials and embodied energy of materials and the ability to achieve economically feasible and sustainable operations. These materials and their embodied energy are generally low value and can be quite complex due to the significant variation in properties leading to potential mismatch among complexity, regulations and available resources. This symposium will provide a forum for papers exploring the valorization of materials and their embodied energy including byproducts or coproducts from ferrous and nonferrous industries, batteries, electronics, and other complex secondary materials. Those papers providing perspective on both the technical as well as policy-based challenges are encouraged to submit.
