Abstract: A method for recovering fibers embedded in a composite material including loading a furnace chamber with a volume of the composite material; thermolyzing the composite material in the furnace chamber, resulting in a 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 thermolyzing operation, 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 thermolyzing is completed therein, to burn the char from the fibers in an exothermic combustion.
