    • A degrading station and apparatus for degrading a material having long molecular chains and obtaining a fluid material having short molecular chains. It comprises: a chamber (2) comprising a first wall (20), a first opening (21 ) for inlet of an organic material having long chains, and a second opening (22) for outlet of a fluid organic material having short chains; a second wall (3) arranged in the chamber (2), facing the first wall (20) for defining a space (4), and dimensioned so as to enable communication between the openings. The first wall (20) and/or the second wall (3) is activatable in rotation so that the organic material in inlet crosses the space (4) in an advancement direction (Y) which goes from the first opening (21) to the second opening (22). The first wall (20), the second wall (3), the first opening (21) and the second opening (22) are reciprocally arranged and conformed in such a way that when one of the walls rotates, the tangential velocity perpendicular to the advancement direction (Y) at the rotating wall increases in the advancement direction (Y) along the whole space (4) so that a friction is determined between the molecular chains of the organic material which in turn determines a production of thermal energy internally of the material so as to degrade the material having long molecular chains and obtain the fluid material having short molecular chains.
