Summary
CHAPTER 1. INTRODUCTION ￜ CURRENT STATE OF RECYCLING IN FRANCE AND EUROPE (REGULATIONS, KEY FIGURES, ETC.): - Key figures - Regulations - Issues: Why recycle end-of-life materials? CHAPTER 2. THE DIFFERENT SORTING TECHNIQUES: - Mechanical sorting methods (screening, trommel, etc.) - Aeraulic separators - Hydraulic classification - Electrostatic and triboelectric separator - Sorting methods based on identification CHAPTER 3. CHEMICAL RECYCLING PROCESSES: - Pyrolysis - Solvolysis: glycolysis, hydrolysis, methanolysis, ammonolysis - Reactive extrusion CHAPTER 4. MECHANICAL RECYCLING PROCESSES: - Single-material vs. multi-material recycling - Degradation of polymers and remedies for degradation - Polymer mixtures - Examples of recovery: automotive sector CHAPTER 5. RECYCLING PROCESSES FOR COMPOSITE MATERIALS: - Thermal recovery of composites (incineration, thermolysis) - Material recovery (chemical recycling, grinding-micronisation) - Mixed recovery (co-combustion in cement works, heat treatment in fluidised bed boilers, high temperature pyrolysis) The practical work sessions associated with this theoretical course provide students with the opportunity to solve a problem in project mode. The problem is presented to students prior to the sessions (e.g. proposing a PET chemical recovery process) and is accompanied by a few examples of scientific articles proposing solutions. On the basis of these articles or articles from their own research, students will propose a plan of experiments that they will carry out in the practical work room. They must then carry it out while varying the parameters in order to validate a protocol and to be able to propose a solution that solves the problem and makes it possible to achieve the expected properties.
Educational goals
Introduce students to the recycling of plastics and composites, and the associated processes. At the end of this course, students will have a good understanding of issues related to the recycling of plastic materials, will have identified the challenges and will be able to propose recycling processes adapted to the planned flow (e.g. polypropylene from end-of-life vehicles).
Sustainable development goals
Knowledge control procedures
Continuous Assessment
Comments: The module is assessed based on the outcome of the practical work results. Students will present the approach followed and the results obtained to teachers and other groups. There will then be a critical discussion of the proposed solutions.
Online resources
PDF course materials are made available to students prior to the course on a sharing platform (Moodle, NextCloud, etc.). Printouts may be provided upon request.
Pedagogy
General concepts are covered using a traditional method (lectures). Carried out in project mode, practical work includes a simulation for creating a product based on specifications (delivered as presentations).
