The active lifetime of each phone is 2 − 3 years, after which it is out of use in drawers or landfills, or sent to non‐OECD nations for reuse or informal recycling [13,22,33]. The estimated ten billion units produced in total by 2010 would contain a total of 2,400 tonnes of Ag, 230 tonnes of Au, and 90 tonnes of Pd. As seen in Table 2, the Au and Ag contents of the combined 2010 sales volumes of mobile phones and computers are equivalent to ~4 % of the global mine production for Ag and Au and ~20% of that of Pd and Co.

Pre‐processing of the EoL products includes open‐sky incineration to remove plastics, ‘cooking’ of circuit Recycling Precious and Specialty Metals 19 boards over a torch for de‐soldering, cyanide leaching, and mercury amalgamation. Over and above their disastrous effects on health and environment, the efficiency of such activities is very low, as well. An investigation in Bangalore, India revealed that only 25% of the Au contained in circuit boards was recovered, compared to over 95% in integrated smelters [9].
