Our team is deeply saddened to communicate that Professor Giuseppe Genon, our friend and collaborator, has passed away on Friday. Professor Genon had been suffering from illness while keeping up with his work at the Politecnico di Torino and in the ongoing course "Wastewater Treatment and Management of Urban Solid Waste" of Hydroaid. As many of you remember, he has been our collaborator for several years: preparing, delivering and tutoring outstanding training programs. In addition to this, those who had the privilege of meeting him in person know he was also a dedicate and kind person, who had his students truly at heart and strived for bringing real contributions with his profession. His passing is the loss of an exceptional individual who did a lot for many. We will all miss him and send our thoughts and prayers to his family at this time of grief.
