The Tetrapak project is a workshop on the use of Tetrapak for the Center for Contemporary Art Luigi Pecci in Prato. The five events of the laboratory allowed the participants to build different objects, from sculptures to jewels, designing shapes and specific solutions according to the chromatic range or the style of the containers of recycled polylaminate. The theme of waste as a resource involves men from all over the planet. The creation and development of a strict relation between virtuous behaviours and quality of life cannot be postponed. Needless to remember the thousands of square chilometres of the five garbage isles that are floating in the oceans. The involvement of the public in artistic projects tied to environmental causes, through the proposal of Public Art, has achieved great results, as attested by the main international events dedicated to contemporary arts.
