Project formed to recover gallium from lamps


Lighting industry WEEE compliance scheme Recolight has formed a consortium with five others to research practical methods of recovering gallium when LED lamps are recycled. The consortium comprises of Recolight, HSSMI, S2S Electronics, Envaqua, E.C. Williams, and the Institute of Material Finishing. The project, named Recovery of Gallium Ionic Liquid (or ReGAIL) is partly financed by Innovate UK, the UK’s Innovation Agency.

Currently there is no recovery of the gallium of gallium nitride when LED lamps are recycled, the consortium said, and the project aims to establish a “circular supply chain” for the metal. This will “reduce the need for extracting raw gallium, and increase the UK’s supply chain resilience and dependency on new resources,” the consortium added. Gallium is a type of metal found in many LED lights which helps them to shine brighter.

Due to a lack of natural sources of gallium in the UK, it says it is “vital to identify ways of capturing gallium through improved recycling”. Alternatively, as the demand for gallium increases, “the UK would need to resort to importing gallium from abroad”. The ReGAIL project therefore creates a “potential competitive advantage for the UK”, ReGAIL explained, by using waste LED lamps as a source of gallium.
