The demands on plastics recycling are constantly increasing, as both legal requirements and economic interests are increasing the need to recycle plastic waste efficiently and sustainably. The industrial use of plastic waste in particular requires the development of suitable conveying systems that are able to handle the often inhomogeneous and light plastic particles. This master's thesis aims to develop a combined dosing and conveying system for a new processing plant that can recycle up to 200,000 tons of plastic waste per year. The material is to be reliably removed from a bunker and conveyed into an extruder with a defined mass flow. The material to be conveyed is shredded plastic fraction with a very low bulk density and problematic material properties. First, characteristic bulk material properties of the bulk material were determined experimentally. After a literature research and with knowledge of the flow properties, three suitable conveying concepts are developed and designed. The functionalities of the concepts are simulated and tested using the discrete element method (DEM). Due to the complexity of the particles, the high number of particles in the system and the associated computational load, the particles must be greatly simplified in order to be able to simulate the discharge and conveying behavior. Based on the simulation results, adjustments and optimizations of the designs are proposed.
