“…Dissipative losses may occur at every stage of the material's life cycle; however, the end-of life (EOL) stage is a noteworthy contributor. A screening of dissipative losses for critical materials has been performed by Zimmermann and Gößling-Reisemann [49]. They found that the majority of critical materials have dissipation rates of over 50%.…”

“…Recovery from the receiving medium later may be technically or economically unfeasible. Technical and economic feasibility is, however, a dynamic feature; materials might be less dissipative in future due to progress of technical knowledge, market situation, and/or destination of the dissipated materials [49].…”

Abstract:Raw material criticality studies are receiving increasing attention because an increasing number of elements of great economic importance, performing essential functions face high supply risks. Scarcity of key materials is a potential barrier to large-scale deployment of sustainable energy and clean-tech technologies as resorting to several critical materials. As physical scarcity and geopolitical issues may present a barrier to the supply of critical metals, recycling is regarded as a possible solution to substitute primary resources for securing the long-term supply of critical metals. In this paper, the main drivers and constraints for critical materials recycling are analyzed from literature, considering indium as a case study of critical materials. This literature review shows that waste electrical and electronic equipment (WEEE) could be a future source of critical metals; however, the reduction of dissipation of critical materials should have much higher priority. It is put forward that more attention should be paid to sustainable management of critical materials, especially improved practices at the waste management stage. This calls for not only more efficient WEEE recycling technologies, but also revising priorities in recycling strategies.

“…The presence of REE and other metals deemed critical have been described in sewage sludge (Kawasaki et al 1998), municipal solid waste (Morf et al 2013), incineration products of other wastes (Zhang et al 2001), metallurgical slags (Binnemans et al 2013b), in the so-called "red mud" bauxite residue generated by the alumina refining industries (Liu, Naidu 2014), in electrical and electronic waste (e.g. Mueller et al 2015;Sommer et al 2015) and in slags (Zimmermann, Gößling-Reisemann 2013).…”

Abstract. The recovery of valuable metals from metallurgical slag disposals is a promising option to protect natural resources, limited due to technology development and increased consumption. The Ad-hoc Working Group on Defining Critical Raw Materials within the Raw Materials Supply Group has proposed a list of critical elements which have the greatest economic importance and meet the requirements of sustainable development in Europe. The goal of this study was to examine steelmaking-and blast-furnace slags from metallurgical processes to determine concentrations of elements of the greatest criticality for Poland, e.g. Nb, Ta and REE, and to discuss the viability of their recovery. Slag analyses indicate enrichment of REE relative to UCC, NASC and average chondrite compositions in blast-furnace slags and Nb and Ta in steelmaking slags. To make recovery of these critical elements reasonable and profitable, it is recommended that they be recovered together with other useful raw materials.
