Owing to technological advancements and energy-saving policies, the demand for LED is increasing, leading to rapid industry expansion. Consequently, efficient recycling of accumulated LED waste has become a growing social concern, and current recycling status of LED waste resources and future directions were reviewed. Currently, waste LED recycling is focused on Ga recovery. Therefore, the development of integrated recycling technologies such as pre-treatment and concentration/recovery of high valued materials is necessary. In this study, we investigated the status and recycling technologies of waste LED and presented prospects.

In general, recyclable items are separately discharged from households and then, hand-sorted into different types of valuables at materials recovery facilities (MRF). However, most of residues after hand-sorting are finally end up with landfill and/or incineration due to lack of separation technologies and economical reasons. In the present study, physical properties on recyclable items obtained from an MRF are investigated to improve the recovery of valuable items. The results of physical compositions based on the sizing tests are also presented.
