The secondary raw materials restarted in the production process can consist of at least three qualitatively different categories of materials: - with the same characteristics as the original materials - with characteristics of new materials, replacing the traditional ones in the same applications from which they originated - with characteristics of new materials, replacing traditional ones in applications other than those from which they originated The first category includes those materials which, after having been separated in the treatment phase, can be added to the virgin material at any stage of its transformation process and are no longer distinguishable from it.
