2019 TMS Annual Meeting & Exhibition: REWAS 2019: Disruptive Material Manufacturing - Scaling and Systems Challenges: Organized by Kaka Ma; Iver Anderson; Sneha Prabha Narra; Fiseha Tesfaye; Elsa Olivetti; Gabrielle Gaustad

The landscape of material manufacturing has the potential for dramatic change as new design techniques (e.g. material genome) and new technologies (e.g. additive manufacturing) begin to scale to industrial production levels. As additive manufacturing reduces the needs for machining compared to conventional manufacturing, has the environmental impact of additive manufacturing been fully evaluated? How will the production of suitable feedstock for AM affect the environment? How will new technologies be scaled efficiently? How will disruptive technologies change the landscape of producing materials? What is the circularity potential for inputs and outputs of these new production routes? How can these systems be optimized? How does the massive scale-up of clean energy technologies affect process flow sheets and recycling (i.e. significant materials demand increases and the need to match the subsequent recycling processes/infrastructure). Other REWAS 2019 Symposia include: - Secondary and Byproduct Sources of Materials and Minerals - Rethinking Production - Cast Shop Recycling Technologies - Education and Workforce Development Proceedings note: There will be opportunities to submit to the Journal of Sustainable Metallurgy for in-scope submissions (Lead: Dr. Julie Schoenung, UC Irvine).

2019 TMS Annual Meeting & Exhibition: REWAS 2019: Education and Workforce Development: Organized by Adam Powell; Christina Meskers; Elsa Olivetti; Gabrielle Gaustad

Integrating sustainability work in the traditional disciplinary degree curriculum is important to advancing the field and training the next generation of material scientists. Also, transitioning knowledge from the research and academic sectors into applied work is critical to realizing sustainability. Papers here are encouraged in novel educational approaches like blended learning, flipped classrooms, MOOCs, etc. as well as approaches for integrating sustainability into traditional disciplinary curriculums like material science. Technology transition, applied learning, and workforce development initiatives will also be highlighted. Other REWAS 2019 Symposia include: - Disruptive Material Manufacturing- Scaling and Systems Challenges - Secondary and Byproduct Sources of Materials and Minerals - Rethinking Production - Cast Shop Recycling Technologies

2019 TMS Annual Meeting & Exhibition: REWAS 2019: Rethinking Production: Organized by John Howarter; Mingming Zhang; Gabrielle Gaustad; Elsa Olivetti

There are additional sustainability benefits with high potential in the production sector. How do we decrease emissions and effluents in production? How can we achieve sustainable process design? How will clean energy technologies be manufactured? How do we measure and quantify embodied energy (how do existing methods fall short and how do we align internationally)? How can we enable cost-effective and efficient collection and reprocessing of wastes? What are technologies and strategies for managing mixed materials. How can trace, tramp, and other unwanted contaminants be removed from secondary streams? What are opportunities for direct use of end of life products to make new products with minimal or no reprocessing? How to reach near zero waste production?

2019 TMS Annual Meeting & Exhibition: REWAS 2019: Secondary and Byproduct Sources of Materials, Minerals, and Metals: Organized by Gabrielle Gaustad; Camille Fleuriault; Neale Neelameggham; Elsa Olivetti

As scarcity and criticality concerns grow, attention has turned to alternative sources of important materials, metals, and minerals. Circular economy techniques, industrial symbiosis, and urban mining are sustainability strategies for obtaining these materials from industrial byproducts, end of life wastes, and other secondary sources. Which new extraction technologies will be needed to enable this material recovery? What are the latest developments made to the existing processes? What are the economic and environmental impact implications of such alternative routes? What kinds of material flow analysis and/or metric standardization is needed for tracking circularity at multiple scales? A specific session on electronic waste and batteries of all chemistries is planned.

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: Environmental Challenges and Opportunities for the Magnesium Industry: Recycling and Sustainability Joint Session: Organized by Elsa Olivetti; Neale Neelameggham

This symposium will provide a forum for papers exploring the current and upcoming challenges for magnesium production, processing and use from an environmental perspective. This might include exploring efficiency in production, use of cover gas in processing to benefits from use of magnesium, etc. Those papers providing perspective on both the technical as well as policy-based challenges are encouraged to submit. A paper submission is required.

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].
