Remanufacturing engineering is the industrialization of high technology maintenance of the waste productions, and it is important technology support of circular economy and energy saving & environmental protection industry. The remanufacturing engineering in China has experienced three periods, namely industrial emergence, scientific demonstration and governmental promotion. Based on performance improvement method and size restitution method, Chinese characteristic remanufacturing engineering takes advanced life assessment technology, nano surface engineering and automated surface engineering technologies as the key remanufacturing technologies, and the main character of which is that the performance and quality of remanufacturing products are at least as good as the new ones of the prototype, with cost at 50 %, energy saving 60 %, material saving 70 %, which will improve environmental protection obviously. The new remanufacturing mode with Chinese character has gradually established and obtained great achievements.
