Zusammenfassung:	A method for recovering fibers embedded in a composite material comprises the steps of: loading a furnace chamber (10) with a volume of the composite material; thermolyzing the composite material (18) in said furnace chamber, resulting in gaseous fraction that is continuously evacuated from the furnace chamber, and a residue of fibers covered with char that is left in the furnace chamber; cracking the gaseous fraction from the thermolysis step, resulting in a mixture of condensable and non-condensable gases that can be recycled; injecting a stream of an oxygen-containing gas into the still hot furnace chamber after the thermolysis is completed therein, in order to burn the char from the fibers in an exothermic combustion.
