| Abstract Text | Electronic equipment (EE) contains important material resources, including bulk materials, precious metals, and critical raw materials such as indium (In) and neodymium (Nd). For an efficient management of these resources, it is important to know where the devices are located, how long they are used and when and how they are disposed of. In this article, we explore the fate of critical raw materials in EE and thus the suitability of their in-use stock for urban mining. With a special focus on the service lifetime, storage time and disposal pathways of different device types, we investigate the past and current quantities of EE containing In and Nd in the stock and quantify the flows between the use, storage and disposal phase. Results highlight the importance of the storage stock, which accounts for 25% of the mass of the total stock in 2014. Electronic devices in Switzerland represent an In stock of over 2 tons and a Nd stock of 38 tons. |
