“…2 is 3 years, as given in all cited reports. However, lifetimes from other studies are often quoted as being shorter (Paiano et al 2013;Judl et al 2012;Osibanjo and Nnorom 2008;Wright et al 1998;Fishbein 2002;Geyer and Blass 2010;Franke et al 2006;Jang and Kim 2010;Li et al 2012;Yin et al 2014;Marukami et al 2010;Rathore et al 2011). There is a range of lifetimes presented in some of the articles, portions of which are longer than 3 years, but where a range is given, the average is stated as being less than 3 years and sometimes less than 2 years.…”

“…These include surveys of consumers' willingness to partake in, or pay towards, recycling Ongondo and Williams 2011a;Yin et al 2014;Polák and Drápalová 2012;Yang 2008;Jang and Kim 2010). As may be expected, these studies are highly dependent on regional and sociological factors, with the referenced studies being mainly relevant to the UK, China, Nigeria, Korea and the Czech Republic.…”

Purpose The aim of this study is to explore the literature surrounding the environmental impact of mobile phones and the implications of moving from the current business model of selling, using and discarding phones to a product service system based upon a cloud service. The exploration of the impacts relating to this shift and subsequent change in scope is explored in relation to the life cycle profile of a typical smartphone. Methods A literature study is conducted into the existing literature in order to define the characteristics of a Btypicalŝ martphone. Focus is given to greenhouse gas (GHG) emissions in different life cycle phases in line with that reported in the majority of literature. Usage patterns from literature are presented in order to show how a smartphone is increasingly responsible for not only data consumption but also data generation. The subsequent consequences of this for the balance of the life cycle phases are explored with the inclusion of wider elements in the potential expanded mobile infrastructure, such as servers and the network. Results and discussion From the available literature, the manufacturing phase is shown to dominate the life cycle of a Btypical^smartphone for GHG emissions. Smartphone users are shown to be increasingly reliant upon the internet for provision of their communications. Adding a server into the scope of a smartphone is shown to increase the use phase impact from 8.5 to 18.0 kg CO 2 -eq, other phases are less affected. Addition of the network increases the use phase by another 24.7 kg CO 2 -eq. In addition, it is shown that take-back of mobile phones is not effective at present and that prompt return of the phones could result in reduction in impact by best reuse potential and further reduction in toxic emissions through inappropriate disposal. Conclusions The way in which consumers interact with their phones is changing, leading to a system which is far more integrated with the internet. A product service system based upon a cloud service highlights the need for improved energy efficiency to make greatest reduction in GHG emissions in the use phase, and gives a mechanism to exploit residual value of the handsets by timely return of the phones, their components and recovery of materials.

“…The sales&new method is a new approach based on the principle of material conservation, while in some previous studies it was called the MFA method (Jang and Kim, 2010;Yu et al, 2010). We specialize the MFA method to estimate the generation of retired mobile phones and name it as sales&new method.…”

“…For instance, Fishbein (2002) estimated number of cell phones retired per year in the US using the classic market supply method, Eugster et al (2007) estimated the retired mobile phones generation in China in the same way; Gao et al (2010) and Polak and Drapalova (2012) forecasted the generation of end-of-life mobile phones in China and Czech Republic using the market supply A method, respectively; Liao and Zhang (2012) made a comparative study based on the estimation results of discarded mobile phones in China using the classic market supply method, time-step method and approximation, respectively. With MFA method, Yu et al (2010) and Jang and Kim (2010) estimated the generation of retired mobile phones in China and Korea, respectively. Moreover, Osibanjo et al (2008) modelled the waste generation by the telecom sector in Nigeria by regression analysis.…”

“…A typical joint reverse supply chain contains four areas of collaboration: (i) waste disposal, (ii) product/part/material in sales, (iii) cost sharing, and (iv) profit distribution (Nnorom et al 2009). Joint collaborations allow logistics operation models to be scaled and benefit from economies of scale as the number of returned mobiles phones increases (Jang and Kim 2010).…”

This study aims to examine the impact of reverse logistics capabilities on firm performance and mediating role logistics strategies. We reviewed three theories of reverse logistics capabilities: (a) Resource-based view of the firm, (b) Transaction cost economics, and (c) Institutional theory. We examined six reverse logistics capabilities: Logistics information management, close-loop capability, supply chain integration, supply chain coordination, conformity capability, and institutional incentives. We examined three reverse logistics strategies: Joint reverse logistics, manufacturer reverse logistics, third-party reverse logistics. We conducted a survey of Chinese mobile phone companies out of which we received 125 usable questionnaires with a response rate of 80%. The results of mediated hierarchical regression support the hypothesis that reverse logistics capabilities influence firm performance. Institutional factors were more significant than supply chain factors. Close-loop capability was the most significant factor. We provide managerial implications and suggestions for future research.
