In closed-loop supply chain (CSLC) networks, low quality of returns reduces the number of usable cores and hence affects the strategic decision of facility location and sizing. This problem can be overcome by adding presorting centers in the CLSC network since presorting costs are typically lower than the costs incurred at subsequent processing stages. Presorting centers can separate poor quality products at the start of the reverse logistics cycle and reduce transportation costs and emissions. A deterministic mathematical model and its robust variant are proposed to investigate the effects of the quality of returns on the CLSC network under the carbon cap (CC) and carbon cap-and-trade (CCT) policies. Numerical experiments are conducted with realistic parameters to demonstrate the effects of varying return quality on total emissions and profit, the impact of presorting center efficiency and transportation cost on the opening of presorting centers, and the impacts of CC and CCT policies on the configuration of the CLSC network. The main insight of this talk is that the carbon cap policy affects the optimal network structure much more than carbon cap and trade.
