The course complements and expands students' knowledge in the field of circular economy and methods of analysing recycled products. Lectures will be dedicated to an explanation of recycling methods of common municipal and industrial waste with a special focus on mechanical and chemical recycling methods. The main aim is to provide a comprehensive overview of what type of recycling method is suitable for recycling a particular municipal or industrial waste and how to analyse the products of chemical recycling methods, especially pyrolysis oils from plastics and biomass. The course consists of the following topics: 1. Introduction to circular economy, legislation, and terminology of recycling methods. 2. Definition and description of mechanical recycling - merits and demerits of recycling. 3. Selected application of mechanical recycling. 4. Definition and description of chemical recycling - thermal and chemical processes. 5. Thermal processes of chemical recycling (pyrolysis, gasification). 6. Selected application of thermal processes (pyrolysis). 7. Chemical processes of chemical recycling - solvolysis (glycolysis, hydrolysis), selective dissolution. 8. Selected application of solvolysis and selective dissolution. 9. Analysis of chemical recycling products, especially pyrolysis oils. 10. Corrosion in chemical recycling. 11. Modern trends in chemical recycling methods. Literature: 1. Harrison et al., Waste as a Resource (Issues in Environmental Science and Technology, RSC Publishing, (2013). 2. R.
