I graduated in Chemical Engineering at the University of Pisa in May, 2023. The topic of my thesis was the valorization of the residues from waste-water industrial plants in order to achieve the goals of the circular economy. During University I had the possibility to experience team work in projects present in the courses of "Methods and management of plants" and "Reliability and safety in the process industry". For other courses ("Unitary operations", "Chemical plants project" and "Analysis and develop of projects") I worked on my own.
