Depending on the states of polyurethane scraps generated in the production sites of polyurethane or recycling center of polyurethane scraps, appropriate recycling technologies can be employed for the recycling of resources. In this study, recycling technologies for the polyurethane scraps were classified into physical recycling, chemical recycling, and energy recycling and reports in the literatures were discussed.
