A joint REWAS-LMD symposium Decarbonization and Sustainability in Aluminium
Primary Processing will be organized as a joint session with Aluminum Reduction
Technology. This session covers decarbonization efforts across the primary and
secondary industries via implementation of alternative, renewable energy
sources, and the optimization of fuel consumption.
Recent technologies or policies used for the purpose of reducing CO2 emissions
in particular, hydrogen reduction, inert anode smelting and alternative sources
of energy for production plants are of interest. Beyond the technologies

A joint REWAS-LMD symposium on Recycling and Sustainability will be organized
as a joint session with Cast Shop Technology. The usage of light metals in the
aerospace, automotive and packaging industries has been rising due to their
outstanding properties. The importance of recycling and sustainable metal
casting has risen in the last decades dramatically due to the increasing demand
on primary resources and environmental concerns. Innovative solutions are
needed to increase the efficiency in metal processing and treatment for complex
scraps. This joint session within the Cast Shop Technology explores novel and
improved recycling technologies for complex scraps, mechanical and thermal
pre-treatment of scraps, new recycling and refining processes, economic and
environmental impacts of recycling, incl. life cycle assessment.
Digitalization and automation are constantly changing the scene of material
processing. In this symposium, particular emphasis is given to the role of
modeling approaches in improving the recycling processes. Digital approaches
can enhance process control, evaluate processing parameters and the quality of
final products. More specifically, the role of process models and simulation
tools for the optimization and development of metallurgical processing will be
explored. Particular focus will be given to monitoring minor elements. Further,
modeling approaches, such as machine learning algorithms, and thermodynamic,
kinetic, and multiphase modeling tools for integrating secondary sources into
the production lines, will be highlighted.
With the electrification of society in general, and mobility and industry
sectors in particular, the volume of discarded batteries and energy materials
are rising. The pathways towards the end-of-life management of clean energy
technologies are essential for the more sustainable future. These encompass
among others, design for R approaches, lifetime extension, and recycling
solutions for current and future technology components.
This symposium covers the key aspects and advancements in, including but not
limited to: the recycling of lithium-ion batteries with a special focus on the
recovery of lithium, aluminum and graphite; recycling approaches for
alternative battery chemistries and types, recycling approaches for wind
turbines (REE magnets, carbon fibers, …) and photovoltaic systems (silicon,
perovskite, ...), as well as systemic perspectives on end of life management
and recycling, including metrics and value chain models.
The technological and societal advancements require the use of advanced
materials and the development of special alloys. Usually critical and strategic
raw materials including metals, minerals, and natural materials are required.
Strategic critical raw materials have economic importance, potential supply
risk, complex production requirements and a fast growth in demand. Therefore,
alternative sources are exploited, often called urban mining, to satisfy the
need of critical metals, to reduce the risk of supply interference, facilitate
industrial symbiosis and increase resource efficiency.
The symposium seeks to highlight the exploitation of secondary sources for
materials production and the utilization of those streams into production lines
while meeting process and products requirements. Research focusing on
understanding the fundamental mechanisms as well as the engineering aspects for
the integration of secondary sources are encouraged. Special focus will be
given on advanced extractive metallurgy methodologies, including sorting and
separation. Articles focusing on life cycle analysis, materials flow and supply
chain resilience analysis are encouraged.

The 21st century is an age of unprecedented opportunity in material science.
Global policymakers have instituted milestones for the reduction of carbon
emissions and refuse, with the goal of promoting a sustainable future. Material
science has enabled significant advances toward these targets, including the
development of fully electric vehicles, implementation of sustainable energy
production and storage technology, and minimization of commercial and domestic
waste streams. It is apparent that the entire lifecycle of a product, from
material extraction to disposal, is as important as the utility the product
offers during its lifespan. Presentations in this symposium will share
innovative ideas for the design of products and processes that will enable a
more sustainable future. Speakers will include professionals from industry who
facilitate processing and product improvements, as well as scientists who are
developing technologies for the next generation of manufacturing processes.
Solicited topics will include:
1. Challenges in designing long-lasting and high-utility products with
sustainable end-of-life plans
2. Design and manufacture of elegant and functional materials with tailored
optical, electronic, magnetic, mechanical, or corrosion properties
3. Developments in the transition from single-use to multi-use products
4. Production of energy and goods using sustainable material acquisition
practices that reduce carbon emissions and waste
5. New material design concepts that improve quality, performance, and
durability of products.
6. Novel engineering and scientific approaches, such as: high-resolution
microstructure characterization, computer aided modeling, and test techniques
that fill the gap between laboratory experiments and industrially relevant
processes.
The supply challenges for many materials and minerals which enable new
technologies has provided new opportunities in recycling of complex materials.
Likewise, the recycling of more conventional materials can also face
techno-economic barriers. This symposium is open to participants from both
industry and academia in areas including recycling of e-waste, energy/battery
materials, critical minerals, ferrous and non-ferrous metals, & process
modeling of recycling. Papers providing perspective on both technical as well
as policy-based challenges or broader materials science challenges toward
sustainability are also welcome.
The Lead – Zinc 2020 symposium builds on the successes of the original 1970
meeting, the subsequent conferences held in 1980, 1990, 2000 and 2010, the Zinc
– Lead symposia in Japan organized by MMIJ in 1995 and 2005, the Lead-Zinc
conference in Germany by GDMB in 2015, as well as the Canadian Lead – Zinc
conferences organized by MetSoc in 1998 and 2008. It will provide an
international forum for the lead and zinc processing industries bringing
together operators, engineers and researchers to exchange information about all
aspects of current processing technologies for primary and secondary lead and
zinc, as well as emerging technologies for both metals. 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. After the symposium, industrial tours are planned to various North
American lead and zinc processing operations.
Topics to be discussed at the symposium include:
* Global factors affecting the production of zinc and lead including the
economic aspects of the industries, product development and marketing
endeavors, and environmental and health issues,
* Surveys of existing smelters and refineries for primary and secondary lead
and zinc production,
* Zinc production technology (roast-leach-electrowinning route including iron
control, pyrometallurgical processes, ISP, slag fuming, Waelz furnace, TBRC and
new technologies including direct concentrate leaching and smelting,
pyrometallurgical refining and oxide ore processing),
* Lead production technology (pyrometallurgical processes such as the ISP,
blast furnace, QSL, KIVCET, SKS-RSKS and TSL, as well as pyrometallurgical
refining, electrorefining, slag fuming and new processes),
* Product applications and marketing (galvanization of steel, chemicals, ZnO,
lead-acid batteries) and new product development,
* Recycling technologies and product life cycle issues (e.g. electric arc
furnace dust treatment and direct de-zincing, secondary lead processing), and
* Fundamental research and basic studies related to new Pb and Zn processes and
to the understanding and basic theories of Pb and Zn processing.
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.

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)
