Mobile phones can contain up to twenty types of metals, including aluminum, antimony, barium, chromium, cobalt, copper, iron, lead, nickel, tin, and zinc (Wu et al., 2008; Lim and Schoenung, 2010). Additionally, the presence of precious metals like silver, gold, and palladium introduces significant impacts into the life cycle due to mining and processing these metals (Silveira and Chang, 2010). Bromine-based flame retardants are also present in mobile phones, as part of the plastics used for the casing of the phone (Wu et al., 2008). Mobile phone batteries are now typically lithium-ion or nickel-metal hydride, which means these batteries contain cobalt, zinc, and copper (Silveira and Chang, 2010).
