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.

2018 TMS Annual Meeting & Exhibition: Solar Cell Silicon: Organized by Shadia Ikhmayies; Neale Neelameggham; York Smith

There is an expanding interest in silicon for solar energy and electronics. The past decade has seen an unsurpassed growth in the solar industry and despite the recession, growth has continued and costs have been cut dramatically along the production value chain. The most important feedstock for crystalline solar cells is high purity silicon. For the industry to mature and grow into green production, improvements in Si production, refining and crystallization processes, emission control and recycling needs to be carried out. Abstracts are being solicited for the following topics: - Silicon feedstock production (reduction of silica and silica ores, advances in furnace design and process intensification, novel techniques of silicon production, thermodynamic and kinetic modelling). - Silicon refining and behavior of impurities (all types of metallurgical upgrading approaches: solvent refining, slag refining, electrolysis/FCC Cambridge process, gas blowing/oxidation refining, plasma refining, vacuum refining, solidification techniques, optimization of the Siemens-like routes) - Advanced silicon separation and all types of wafering techniques, thin flexible silicon films, interaction of materials with silicon during the processes and novelties in ingot growth) - Life-cycle assessment of solar silicon processing - Recycling of solar silicon components, solar cells and electronic components - Characterization of silicon materials for solar cells

2018 TMS Annual Meeting & Exhibition: Stored Renewable Energy in Coal: Organized by Neale Neelameggham; Sarma Pisupati; John Howarter; Huimin Lu

The symposium will cover fundamentals of storing energy in nature in the form of coal, - such as photosynthesis and decay of life utilizing underused energies for endothermic biotic reductionsand the recovery of such stored energies . Examples of underused energies are solar photonic energy, lunar energy, wave power, decay reactions in soil etc. Recovery of energy will include how to effectively recover the stored energy for food production, by intermediate compounds formation prior to becoming CO2 and H2O vapor and regeneration which sustain human population growth, as well as other energy conversions. The symposium will cover subjects other than the conventional combustion reaction- energy conversions into motive power, electric power. The symposium will also include discussions on abiotic reactions leading to the formation of alloys of carbon, hydrogen, oxygen linked by nitrogen and sulfur in naturally found coal. [Some examples of naturally found solid elements familiar to metallurgists are native copper, diamond, graphite, silver, gold and sulfur].

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.

2016 TMS Annual Meeting & Exhibition: REWAS 2016: Organized by Randolph Kirchain; Bart Blanpain; Anne Kvithyld; Christina Meskers; Elsa Olivetti; Jeffrey S. Spangenberger; Diran Apelian; Brajendra Mishra; Neale Neelameggham; John Howarter

Every sector faces unique challenges in the transition to sustainability. Across each, materials will play a key role. For each respective sector, these sessions will explore the trends and drivers toward sustainability, the enabling materials technologies, and the tools to evaluate their implications. In particular, this session is seeking talks dealing with challenges and solutions in: - Transportation - Built environment (including buildings and infrastructure) - Electrical and electronic equipment and infrastructure (EEEI) - Energy production and storage This session will require the submission of a manuscript of three to six pages in length. In most cases, those articles will appear in the 2016 REWAS proceedings. If topically appropriate, the submission will instead appear in the Energy Technology, Magnesium Technology, or Aluminum proceedings. Approximately 10% of submissions will be invited to submit a revised and expanded manuscript for publication in a special edition of the Journal of Sustainable Metallurgy. REWAS 2016 – Towards Materials Resource Sustainability Society faces grand challenges today, as the status quo is not sustainable. New solutions need to be found and the materials community will be central to those solutions. Specifically, the materials and metallurgical industry is strategically positioned to contribute via the establishment and selection of sustainable processes, materials and recycling solutions. Realizing those solutions, however, will require collaboration and cooperation across disciplines and across the stages of the product life cycle. REWAS 2016 will provide an interdisciplinary platform where the materials and metallurgical professional can interact and exchange with other stakeholders and research fields to facilitate the transition to a more sustainable industry and society. The REWAS 2016 symposium will be organized along three themes: 1) Realizing sustainable products and systems 2) Enabling sustainability 3) Understanding sustainability
