The Luminophorous Powder Recycling Plant utilises a patented chemical process to produce valuable rare earth metals by recycling lamp bulbs. The process produces high purity rare earth metal oxides such as Yttrium oxide and Europium oxide as well as non-toxic Mercury sulphide (cinnabar), from the fine residues (luminophorous powders) of the lamp. The sale of the rare earth metals can help to drastically reduce the treatment costs for the residues.
