| Contents | In modern process engineering a central role is played by biological processes that lead to the sustainable exploitation of renewable natural resources to obtain new materials and/or energy, to the biological or chemical treatment of waste or effluents to obtain energy and/or new resources. The course program starts from the study of the chemical and chemical-physical characteristics of some types of recovered biomass, such as agricultural and agro-industrial waste, solid urban waste, sewage sludge, and then moves on to industrial applications of sustainable processes. Among these, some examples of biorefineries for the production of bioethanol, bio-oil will be examined; biodiesel. Furthermore, the anaerobic processes for the production of biogas from biomass of different nature and the integrated anaerobic-aerobic processes for the treatment of municipal solid waste which lead to the production of biomethane and composted fertilizers will be taken into consideration. As regards the polluted wastewater treatment plants, the activated sludge processes and the biological and chemical processes for the removal of nitrogen and phosphorus will be described. |
| Reference texts | Didactic material provided by the teacher. |
| Educational objectives | The aim of the course is to provide the student with scientific and engineering knowledge necessary for the understanding, analysis and design of industrial biological processes in a sustainable and circular economy scheme. |
| Prerequisites | Basics of the chemistry course. |
| Teaching methods | The course is organized as follow: - Lectures on all subjects of the course; - Classroom exercises aimed for a correct application of the concepts developed for the resolution of numerical exercises and problems of practical application. During the course the student is encouraged to work in a quantitative way over all the studied phenomena, using appropriately the involved physical and chemical quantities. This is done through theoretical frontal lessons and carrying out practical laboratory demonstrations and guided visits to prototype and industrial reactors. |
| Other information | Frontal lessons: three/four weekly hours. Tutorial discussions with experimental demonstrations in laboratory and numerical exercises. Guided tours to chemical industries of interest can be organized. The timetable and Classroom can be downloaded at the following Web address: http://www.ing1.unipg.it/didattica/studiare/orario-delle-lezioni |
| Learning verification modality | The exam consists of a written test and an oral test. The written test consists of the solution of 4-5 problems/multiple choice tests and/or 1-2 short compositions. The test has a duration of 1 hour and 30 minutes and is designed to evaluate tha ability to correctly apply the theoretical knowledge, the understanding of the proposed issues, and the ability to communicate in written form. The oral test consists on an interview of about 20-30 minutes long. |

| Educational objectives | The aim of the course is to provide the student with scientific and engineering knowledge necessary for the understanding, analysis and design of industrial chemical processes in a sustainable and circular economy scheme. The first part of the course is dedicated to learning and to the application of the fundamental laws of thermodynamics and chemical kinetics, for a proper understanding of heterogeneous catalytic phenomena. The second part is devoted to the study of transport phenomena of matter and energy, useful for understanding the working conditions of different types of industrial chemical reactors. In the final part, the course provides an overview of the main industrial sustainable processes through the study of the most recent innovative technologies in the production of hydrogen, ammonia and in carbon dioxide conversion into fuels in a circular economy scheme. |
