Abstract

The purpose of this paper is to estimate and assess a future state of domestic copper supply from a viewpoint of sustainability. The authors develop a simulation model of material flow of domestic copper resources and then estimate the demand and the supply toward 2030. A recycle flow with time series is considered as well for the estimation. Automobile, electric appliance and construction industries are considered in this paper under the scope of recycle laws in Japan. The simulation result illustrates that copper stock in market is estimated to be 4.1 million tons and the copper supply produced from scrap metal is 120 000 tons. Furthermore, the result prospects shortage of copper resources as much as 54 000-59 000 tons against the domestic demand in 2030 even considering improvement of the recycle system. Therefore, the authors conclude that domestic copper resource is not sustainable in Japan and thus emphasize two important countermeasures such as reducing copper usage for the next generation vehicle and further sharing of recycled resources among other industries.
