Recycling-oriented characterization of plastic frames and printed circuit boards from mobile phones by electronic and chemical imaging

Mechanical pre-treatment of mobile phones and its effect on the Printed Circuit Assemblies (PCAs)

“…Similar results have also been reported in the other studies (Huisman, 2004;UNEP, 2009bUNEP, , 2013.The Si originated mainly from the glass in the screen but also from the PCB's glass fibres and electrical components such as semiconductors (Palmieri et al, 2014;UNEP, 2013 Plastics are used mainly in the casing of mobile phones and in the epoxy resin of the PCB (UNEP, 2009b). The TOC content varied between the large and small mobile phone.…”

“…The research on the treatment of mobile phones has focused on the characterization of different types of mobile phones to identify their material composition, valuable metal concentrations as well as impurity levels Hakelüken and Buchert, 2008;Palmieri et al, 2014;UNEP, 2009a). In addition, research on the further treatment of the PCA to separate metals from organics as well as alternative metallurgical recovery methods for PCA has been carried out (Kasper et al, 2011;Yamane et al, 2011).…”

An innovative recycling process to obtain pure polyethylene and polypropylene from household waste

“…Several studies have been carried out also in waste recycling sector, i.e. glass recycling (Bonifazi and Serranti, 2006), compost product quality control (Dall'Ara et al, 2012), characterization of end-of life mobile phones (Palmieri et al, 2014) and characterization of different plastics (Serranti et al, 2011Ulrici et al, 2013;Luciani et al, 2013). Both MDS and HSI were applied to the same PO coming from Romanian and Dutch household waste (HW) to assess and validate the performances of such technologies for PO waste sorting and quality control.…”

Identification and thermomechanical characterization of polymers recovered from mobile phone waste

“…The mobile phone waste volume is accordingly escalating at a fast pace owing to their very short life cycles. It has been projected that the average life cycle of a mobile phone has come down to 6-18 months in developed countries, whereas this is slightly higher in developing countries [10]. This is attributed mainly to the rapid innovation in mobile phone technology, where an advanced featured phone is released every now and then, making the user to discard his old phone and buy the newest version [11].…”

“…By collective use of above-mentioned characterization techniques, most of the literature revealed that major share of plastics used in mobile phones is made up by engineering gradeplastics, such as PC, PC/ABS blends, HIPS and ABS, which may still possess high value in terms of performance and economy, making them ideal for reuse and recycling [10,12,13].…”
