Abstract: The escalating demand for rare metals, driven by their pivotal role in IoT and the energy transition, presents complex challenges for supply chains. This study explores rare metal management, focusing on the key drivers of consumer concern regarding ethical and environmental issues. Based on 18 in-depth interviews, the research examines how consumer perspectives influence the sustainability of rare metal supply chains. The central research question addresses: "Drawing on consumer perspectives, how can the key drivers and solutions identified be leveraged to enhance sustainability in the supply chain processes of rare metals?". Findings highlight solutions such as improved product design, substitution strategies, and enhanced recycling initiatives. An analysis chart links these consumer-driven solutions to sustainable supply chain practices. Using a Grounded Theory approach, this article contributes to the sustainable supply chain literature by offering actionable insights for firms seeking to align their practices with ethical and environmental expectations.

Keywords: rare metals; sustainability; SCM; supply chain management; drivers; issues; solutions.
