Recycling concepts for short-fiber-reinforced and particle-filled thermoplastic composites: A review

Short-fiber-reinforced thermoplastic composites (SFRTCs) and particle-filled (PFTCs) are widely used in various industrial sectors, from automotive to electronic appliances, building constructions domestic equipment. Their environmental impact could be significantly reduced through both open closed loop recycling, which allows a reduction of the usage new resources limit energy consumption CO2 release associated their production. The main challenges opportunities recycling SFRTCs PFTCs currently represented by i) reprocessing (also called mechanical recycling), use recycled matrices ii) fibers, iii) waste composites, iv) chemical recycling. Opportunities current limitations strategies technologies for here reviewed.
