Obiettivi dell'insegnamento

The course fits into the overall program curriculum pursuing some of the defined general learning goals. In particular, the course contributes to the development of the following capabilities:

  • Understand context, functions, processes in a business and industrial environment and the impact of those factors on business performance

  • Design solutions applying a scientific and engineering approach (Analysis, Learning, Reasoning, and Modeling capability deriving from a solid and rigorous multidisciplinary background) to face problems and opportunities in a business and industrial environment

  • Develop new ideas and solutions in business and industrial scenarios evolving over time

Risultati di apprendimento attesi


  • Understand: The students will learn the key definitions of circular economy business processes, the underlying motivations, and the boundary conditions affecting the success of this business solution. Moreover, they will learn the key role of advanced de-and remanufacturing systems in view of the development of circular economy business models. Several real-life examples will be discussed in order to support the in-depth understanding of business practices.
  • Design: The students will learn scientific and engineering methods in support of an efficient design and management of advanced demanufacturing and remanufacturing systems. 
  • Develop: The students will learn the most relevant circular economy problems of the future and will be challenged with the analysis of future technology and business innovations to support these emerging needs.  

Argomenti trattati

The economical and environmentally sustainable treatment of end-of-life products and industrial waste by de-manufacturing processes is the core topic of this course. De-manufacturing includes the set of technologies, tools and knowledge-based methods to remanufacture and re-use functions and to recover materials from industrial waste and post-consumer high-tech products, under a circular economy perspective. This course provides competences related to mechanical de-manufacturing processes and systems, with the objective to design and operate these technologies in environmental and economical sustainable way, in different industrial settings. 

The course will be structured to cover the following topics:

-       De-manufacturing paradigm: definition of de-manufacturing systems and examples of industrial applications; de-manufacturing performance measures; integrated process and system view of the problem.

-       De-manufacturing technologies: description of mechanical de-manufacturing processes, including disassembly, re-manufacturing and recycling technologies; mechanical size-reduction and separation processes; the role of statistical and mechanical models in the design of de-manufacturing processes; advanced de-manufacturing technologies based on automated optical systems.

-       De-manufacturing systems: features of de-manufacturing systems; material mixtures and granular flow models; multi-stage de-manufacturing systems modeling; performance evaluation and design of de-manufacturing systems; flexibility in de-manufacturing systems.

The students will carry out laboratory activities to develop hands-on knowledge on specific processes and process-chains.

Modalità di valutazione
The course is based on lectures, integrated with exercise sessions, also in computer rooms, as well as laboratory sessions with hands-on and experimental activities at lab scale. Moreover, optional industrial visits will be organized.
The exam includes a written part and an oral part. Optional seminars and small projects will also be offered to deeply analyze specific topics of the course in small teams. The quality of this integrative work will be reflected in the final mark.
