Due to the need to protect the environment and some circumstances beyond a manufacturer’s control (such as product recalls), product returns have been introduced to the supply chain. Introducing product returns has led to the formation of closed loop supply chains, that is, situations in which organisations both manufacture and remanufacture their own products. Closed loop supply chains have been known to be uncertain in the timing, quality and quantity of the returns. In addition to these uncertainties, most organisations lack the necessary infrastructure and technology to perform reverse logistics operations on their own. For this reason, they seek assistance from external parties. Whilst the rapid pace of e-commerce has led to manufacturers adopting dual channels for selling their products, in closed loop supply chains, the dual channel has been defined by more than just selling products both offline and online. This paper investigated how dual channel have been utilized to address issues in closed loop supply chains. A content-based analysis was carried out for 57 papers. The identified characteristics of these papers were classified into 9 categories. By reviewing literature on dual channel supply chains, the paper was able to identify the ways in which different channels are formed in closed loop supply chains. The purpose of the paper was threefold. Firstly, the literature review described the general characteristics of dual channel closed loop supply chains based on what was revealed by existing literature. The review also classified literature based on the definition of dual channel CLSC, research methodology and. Finally, the research proposed some meaningful gaps and directions for future research. The results of the review showed that there is need to expand literature on the competition of channels, greening strategies and carbon emmissions and supply chain dynamics and stability in dual channel closed loop supply chains. Future research should also consider relaxing some assumptions and incorporating real case studies.
