Abstract Scope Lighting emitting diodes (LED) have impacted lighting products market. Its efficiency turned them the best choice for lighting. Consume has increased and also the amount of waste. LED can be composed by some valuable and critical metals, such as silver, copper, yttrium and gallium. World demand for these metals in technological applications has attracted attention to urban mining, which also leads to circular economy. For this reason, LED recycling process can contribute with secondary source of critical metals and also has environmental benefit. This work aims the characterization analysis of wasted LED to define a recycling route. Methods such as SEM/EDS, ICP-OES, FTIR and EDX was executed to analyze LED lamps components and surface mounted device (SMD). Results showed the presence of copper, yttrium, gallium and silver in SMD and Pb/Sn as electric welding in lamps of some companies. Consecutively, recovery of metals may guarantee feasibility and reduce waste discharge.
