The participate institution in China in this project: Tongji University; Southeast University; Tokyo University; Shanghai Municipal Engineering Design Institute (Group) Co.,LTD.; Jiangsu Rongda New Material Co., LTD.; Shanghai SANME Mining Machinery Corporation.
Group leader of Chinese research team: Prof. Xiao Jianzhuang (Tongji University), Prof. Zhang Yamei (Southeast University).
Group leader of Japanese research team: Prof. Takafumi Noguchi (Tokyo University).
The group leaders of the Chinese research team and the Japanese research team are responsible for the overall arrangement of decision-making, implementation and daily work, and ensure the normal arrangement and deployment of the project.
The recycling and the municipal water supply and drainage system in Japan is more mature than the system in China. At the same time, The efficient industrial chain of the recycling and utilization of construction and industrial wastes in Japan from the legal, policy and other aspects.
The key point of the operation is to solve the problem of the disjunction of the various links in construction and industrial waste by learning from the Japanese experience in the condition of China’s situation. The recycling product will be available for the recycled concrete structure construction in the sponge city.
