Prospecting reusable small electrical and electronic equipment (EEE) in distinct anthropogenic spaces

Abstract

The generation of Waste Electrical and Electronic Equipment (WEEE) continues to escalate yearly because of high demand for state-of-the-art and affordable devices. This demand is particularly strong for small consumer electrical and electronic equipment whose usage cycle is waning due to fashion and technological obsolescence. As a result, there is potentially a large ‘pool’ of unused, reusable devices within urban spaces (anthroposphere). This study aimed to assess the magnitude of the reusable stock of EEE with the view to recovery and release into the circular economy. An online questionnaire survey was conducted within a regional group of universities in the United Kingdom to assess the prospects of reusable small EEE within this distinct urban mine (DUM) cluster. The study provides new, distinct definitions for types of DUM, hoarding and stockpiling, and new data for a ‘meso‑level’ DUM on ownership levels and hibernating stocks of reusable EEE. Results show that ownership levels were high, with multiple ownership of devices common and a high degree of product stockpiling and hoarding. Estimates show a stockpile of ∼400,000 small EEE within the survey zone and over 17 million devices across the UK with reuse values of >£13 million and >£571 million, respectively. The frequency of device stockpiling is likely due to perceived residual value. The study suggests that exploitation of reuse value requires prompt recovery of stockpiled items as extended periods in hibernation will result in technical obsolescence, particularly with information and communication technology (ICT) devices. Such recovery requires tailored protocols that considers DUM scale, product reusability, recyclability and redistribution.
