Located within Città Fiera, 1,000 square meters in the basement, a store selling second hand goods, under the brand "Mercatino", representing the non-industrial sector of the reuse of resources (RNI) carrying out an important ecological project: the reuse of used items as an ethical and social system in saving the environment. This ecological criterion has encouraged the spread of a real system of "territorial protection" that every year allows you to save objects that become resources, preserving them and therefore avoiding environmental impact.
A culture, that of the re-use, promoted and developed by Antonio Maria Bardelli and Simonetta Cappellari, owners of the store in Città  Fiera for many years. The store, present in the shopping center since 2004, has undoubtedly contributed to a process of development towards this kind of practice, which sits in nicely with the virtuous Friuli Venezia Giulia region, helping to encourage policies of environmental sustainability, underlying its social function and environmental benefits.
