Learning outcomes
The course provides in-depth elements, compared to the knowledge acquired in the Bachelor's degree, for analysis, concept design, final and construction of the plants. They provide expertise, technical and methodological level, for the student's education compared to the path that leads to the design of the plant. Are finally shown some significant research activities in the environmental and energy sector - with particular reference, for example, to energy recovery from renewable sources, such as biomass - with emphasis on the technical and scientific level as regards the engineering of experimental plants.
