Résumé :	Carbon fiber reinforced polymers (CFRP) are classified as materials with high development potential. CFRP has exceptional properties such as high stiffness and strength combined with low density. However, recovery of the carbon fibers from the surrounding matrix is difficult. Currently, industrial recycling is mainly carried out by pyrolysis. A biotechnological recycling process would be a complementary alternative. The feasibility of such a process was investigated on the basis of the metabolic activity of specific microorganisms that are able to recycle such complex materials.
