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.
A child's passport costs Â£46. How long does it take to get a passport? It should usually take three weeks to renew a standard adult or child passport. If you need a new passport more urgently, you can pay extra to book an appointment at a Passport Customer Service Centre and get your passport on the same day for Â£128 or within a week for Â£103. However, ordering an adult passport for someone who has not had one before can take six weeks, and the fast-track service is unavailable. During busy times, including the run-up to Christmas and school holidays, waiting times can be longer.
