The invention relates to a installation (4) for recycling composite materials comprising a horizontal reactor (5) with a first zone (1), second zone (2) and third zone (3), which are leak-tight and independent, aligned with and separated from one another by means of gates that allow the passage of the composite material to be recycled only when the process has ended in a previous zone. The first zone (1) comprises a rotation mechanism (9) for rotating the material and gas outlet means (8). The second zone (2) comprises air injectors (10) and gas outlet means (11). The third zone (3) comprises cooling means.
The invention also relates to a method for recycling composite materials comprising a first pyrolysis phase, a second gassing phase for gassing the material resulting from the first phase, and a third cooling phase for cooling the reinforcement material.
