OPAK (OPtimized PAcKing logistics in the life cycle economy) was a project with a focus on the optimisation of the redistribution of plastic materials for recycling processes. With the RFID-system technology and the optimisation of available technological infrastructures, it was planned to improve the logistic process units of those materials. In the course of the project a research demonstrator providing identification and positioning of packing items was built with the aim of generating experiences with RFID-systems in real-life situations. During the project, a method for tracking and tracing with RFID as the corner stone technology for both identification and positioning was developed.
