This game was designed to popularize plastic recycling in a time in which it was still pretty unusual, at least in Italy. Players must set a collection of 4 diofferent plastic objects, getting them from leftovers of plastic. Double objects can be either traded or destroyed to get more raw materials. Leftovers can also be burned to get energy. The game has been published as a large magazine to be diostributed for free in schools all over Italy. "Il gioco dei minerali" is reminescent of this game: Il Gioco dei Minerali
