ST-25 [Trans-Division Symposium]
Circular Economy Driven by Chemical Engineering (Changed to Virtual)

Organizers: Gotoh Takehiko (Hiroshima Univ.), Ogata Takeshi (AIST), Kawakita Hidetaka (Saga Univ.)

In recent years, a shift to a circular economy from the linear economy has attracted much attention. The shift from the society of mass production and mass disposal to the society of recovery and reuse is required for environmental and resource protection. In this symposium, we will discuss about the efficient separation and recovery process, the renewable material producing process, and the efficient recycling system for the efficient reuse of waste plastics and metals to produce the next product. This is trans-division symposium organized by the Separation Processes division, the Materials an Interfaces division, and the Environment division.

ST-25, SY-56, SY-64, SY-65, SY-70 were changed to Online session.
