This paper is a literature review of challenges within the remanufacturing system. Thechallenges in the remanufacturing system has been categorised in a collection phase, aremanufacturing process phase and a redistribution phase which the challenges havebeen presented according to. The causes and effects of each challenge have beenexplored and are presented in this paper. The final result is a compilation figure with thechallenges for the whole remanufacturing system. In general uncertainties and complexitycan be seen as the main characteristics for the challenges within the remanufacturingsystem.CAN-REMA
