2018 TMS Annual Meeting & Exhibition: Deriving Value from Challenging Waste Streams: Recycling and Sustainability Joint Session: Organized by Elsa Olivetti; John Howarter; Fiseha Tesfaye

For many products, there is a significant mismatch between the technical needs for responsible treatment of secondary and byproduct materials and the ability to achieve economically feasible operations. These feedstocks 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 secondary and byproduct feedstocks including for batteries, electronics, and other complex secondary materials as well as recycling technologies. Those papers providing perspective on both the technical as well as policy-based challenges are encouraged to submit.

2017 TMS Annual Meeting & Exhibition: Advances in Environmental Technologies: Recycling and Sustainability Joint Session: Organized by John Howarter; Mark Kennedy; Naiyang Ma; Elsa Olivetti; Randolph Kirchain

This symposium will provide a forum for papers that relate to advancements in all aspects of technology that aims to control pollution or address other environmental challenges in industrial settings for processing and production. The organizers are soliciting papers from authors who are engaged in scientific, governmental regulatory and engineering aspects of off-gas treatment such as: gas cleaning (wet or dry scrubbers, acid or SO2 plants), filtration (bag house and wet/dry ESP's), among others. Topics of interest also include the interaction of new process technology and the minimization of environmental impact in sustainable processing and operations., The management of recycled feedstocks are of particular interest, due to: (i) the complexity of the feedstocks and processing, (ii) the need in many cases to simultaneously apply new technology and (iii) the requirements for strict environmental protection. Authors are encouraged to submit papers that discuss technical and economic issues related to environmental compliance, associated with plant operations and industrial practices of both new and conventional metallurgical processing.

2017 TMS Annual Meeting & Exhibition: High Temperature Electrochemistry III: Organized by Prabhat Tripathy; Guy Fredrickson; Boyd Davis

Over last several years, increased research and development activities in the field of High Temperature Electrochemistry have been reported in several seminal publications in various journals dedicated to the discipline of electrochemical science and technology. These include battery science and technology, reactive and refractory metals, nuclear materials, light metals, and recycling industry. Of late, recycling industry has shown some remarkable developments in recovering valuable materials from recyclable materials that include spent batteries, magnets spent catalysts. Non-aqueous electrochemistry continues to play an important role in materials world. The time is rife to hold the third biennial symposium, titled, “High Temperature Electrochemistry III” to discuss many recent developments that have taken place in the domain of materials electrochemistry. The specific topics of interest for this symposium include the science and technology of molten salts, molten oxides and ionic liquids as applied to materials research including recycling of scraps, waste materials and manufacturing wastes. Papers covering all aspects of theoretical, experimental and modeling studies are being solicited for discussion in the conference.

2016 TMS Annual Meeting & Exhibition: 7th International Symposium on High Temperature Metallurgical Processing: Organized by Jiann-Yang Hwang; Tao Jiang; P. Chris Pistorius; Gerardo Alvear; Onuralp Y�cel; Liyuan Cai; Baojun Zhao; Dean Gregurek; Varadarajan Seshadri

This will be the seventh international symposium on thermal processing of minerals, metals and materials that intend to promote physical and chemical transformations in the materials to enable recovery of valuable metals, to produce or treat products such as pure metals, intermediate compounds, alloys (including steel), ceramics, and other materials. The symposium will be open to participants from both industry and academia and will entertain innovative high-temperature technologies including those based on non-traditional heating methods as well as their environmental aspects such as handling and treatment of emission gas and by-products. Since high-temperature processes require high energy input to sustain the temperature at which the processes take place, the symposium intends to address the needs for sustainable technologies with reduced energy consumption and reduced emission of pollutants. Papers that describe innovative methods for achieving impurity segregation and removal, by-product recovery, waste minimization and/or energy efficiency are particularly welcome. Also of interest are papers on the various technical, economic, and environmental issues associated with commercial-scale high temperature processing methods.

2015 TMS Annual Meeting & Exhibition: Drying, Roasting, and Calcining of Minerals: Organized by Thomas Battle

These are very common unit operations throughout the metallic and non-metallic mining industries. This can involve chemistry as simple as water removal at low temperatures, to the separation of moisture from bound hydrated compounds, to various high temperature chemical reactions to make subsequent operations easier. This type of unit operation has rarely been considered in a single symposium, so we have here a unique opportunity for interactions, both within TMS and with sister societies.
