In this paper, we highlighted the importance of integrating environmental goals into the production system. We recommend the establishment of closed-loop production systems in a supply chain level. To realize closed-loop production systems, we introduced the concept of sustainable supply chain networks. With a SSCN, it is possible to shift successfully from a flow economy to a circular economy by combining environmental and economic issues, thereby improving eco-efficiency.
Standard passport processing generally takes between four to six weeks, but it can take longer during peak travel times.
