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

Following the successful edition in 2016, the Symposium is devoted to academic and industrial partners working on the substitution and recyclability of critical raw materials (CRM) 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 have been recently defined 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.

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), 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 alternatives 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 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. The symposium is organized by members of the EIP RESET commitment, and will therefore be included and publicised within the program of activities of the commitment.
