Contents The course aims to illustrate the main processes and methods for the recovery and recycling of polymeric materials: the aspects to be considered in the management of a plastics recycling process, the degradation phenomena in the processing and service life of plastics, the classification of recycling technologies (primary, secondary, tertiary and quaternary) and examples of applications of recycled plastics. Emphasis will be placed on the definition of sustainability of polymeric materials, processes and production of polymers from renewable sources, biodegradability of polymeric materials, use of natural polymers and synthesis of biodegradable polymers

Contents The course is aimed at learning the basic principles leading to the recovery of secondary raw materials from the industrial waste, waste and by-product cycle from the perspective of circular economy principles. The program focuses on the following topics: Waste management and regulatory context; Waste classification; Separate collection; Classification of different fractions; Treatments for recovery and recycling of different fractions.
Educational objectives The purpose of the course is to provide the student with the scientific and engineering knowledge necessary for the understanding, analysis and design of material recovery technologies in a logic sustainable and circular economy.
The course provides an overview of the main types of process
sustainable industrial chemicals through the study of the latest innovative technologies in the production of hydrogen, ammonia, and carbon dioxide conversion processes to fuels in a circular economy logic.
Prerequisites Knowledge acquired in Chemistry courses
Teaching methods The course is organized as follows: - Classroom lectures on all course topics.
Learning verification modality The examination includes an oral test
