Abstract Electrical and electronic equipment (EEE) generates very complex waste
due to the wide variety of components such as metals, polymers, ceramic materials,
and composite elements. In addition, the growing consumption of these devices due
to technological development increases the rate they are disposed of. When impropT. A. da Silveira · E. C. A. dos Santos · A. V. Colling
