As one of the most widely used thermosets due to its excellent performances, epoxy resin (EP) is in various fields and often employed as a component composite actuator devices, strengthening their mechanical properties. However, expanding production EP inevitably leads accumulation waste end-of-life equipment corresponding increasingly serious environmental problems. This review summarizes recycling strategies EP, divided into two perspectives: from wastes sources. Chemical expected be future treatment, we discuss chemical methods existing based on different mechanisms, including selective cleavage ester bonds, C–N C–O bonds. On other hand, vitrimer networks dynamic covalent linkages are also outlined, which can respond multiple external stimuli provide materials with recyclability origin. Therefore, use actuators prevent generation throughout whole lifecycle. We present some issues concern both waste-based source-based emphasize significance scaling-up. Finally, summarized current situation perspectives aim making practical contributions issues.
