In the wonderful setting of the Council Hall of the Municipality of Asolo, on Saturday 24 September 2022 we were guests of the Traveler Festival, an event dedicated to "travellers" understood as those who undertake a physical journey but also of the intellect and the soul. Together with other fellow entrepreneurs we spoke with the "Center For Sustainability C4S" of the Ca' Foscari University Foundation of Venice, taking stock of sustainability, techniques and technologies in the context of the Circular Economy, models for evaluating economic, environmental and social impacts .
