Substitution and recycling of critical raw materials in optoelectronic, magnetic and energy devices III

Following the successful editions in 2016 and 2018, the Symposium is devoted to academic and industrial partners working on the substitution and recycling of critical raw materials (CRMs) in electronic, magnetic and energy harvesting devices. The objective is to strengthen the synergies in this community and promote the development of new efficient CRM-free/lean devices.


Raw materials are the basic, but fundamental, elements for a wealth of current technological applications. However, some of these materials (14 elements) have been defined since 2011 by the EU commission as “critical” due to the high risk of supply shortage expected in the next 10 years and for their importance to the European industry. Thus, their (total or partial) substitution and recycling are essential for Europe’s economy. This list has been updated to up to 27 elements in 2017.

Many technologies with a high impact on the quality of life rely on critical raw materials (CRMs) as key elements, from lighting devices (LED, OLED, CFL: rare earths, like Ce, Y, Eu and Tb, In  as CRMs) to energy harvesting devices (transparent conductive layers, solar absorbers, caloric materials), permanent magnets (SmCo, NdFeB), catalytic converters, electrode catalysts in fuel cells (Pt group metals (PGM) and Rh-based catalysts) and rechargeable batteries (rare earths, graphite, Co, Li and Ni as CRMs). New research and development activities are required to improve the fundamental understanding of new material solutions containing reduced or no critical content while maintaining or enhancing the performance of the materials, components and products. The design of the alternative compounds, the control of growth process coupled with accurate characterization are mandatory for further development of new CRM-free/lean devices.

The symposium provides an interdisciplinary and intersectoral platform to discuss about CRM alternatives from the modelling, synthesis, characterization, processing and device integration viewpoints. Bringing together researchers from academia and industry, we aim at increasing the interaction among scientists, engineers, and students working on different areas of the CRM field that are too often treated separately.
