In 2004, cell phone manufacturers published more comprehensive life cycle assessments of cell phones [23, 24]. Other environmental assessment methods, like environmental footprint analysis and material input per unit service, were also explored but with mixed results [25, 26]. Huisman [27] applied his own environmental assessment methodology of e-waste recycling to cell phones, while Scharnhorst et al. [28] conducted life cycle assessments of an entire cell phone network with different recycling scenarios. Several leaching assessments of cell phones are also available in literature [29–31]. Uryu et al. [32] provide an assessment of gallium and arsenic releases due to cell phone incineration. In 2005 and 2006, Nokia published the final reports of its Integrated Product Policy Pilot Project with fairly comprehensive overviews of life cycle environmental assessments and improvement options [1, 33, 34]. At the same time, the Mobile Phone Partnership Initiative between the United Nations Environment Program’s Basel Convention and most cell phone manufacturers published a series of guidelines on environmentally sound cell phone end-of-use management [35].
