Considering the Risk of Spilled EOL
to Overseas

Abstract In recent years, the demand for rare resources used for high-tech products has been increased due to growing populations and industrial developments.
Since rare resources are limited in producing countries, countries that cannot produce
them at home are expected to become depleted. Therefore, it is important to keep
resources by recovering and regenerating rare resources from End-of-life product
(EOL). From this, the formation of a recycling-oriented society that considers regeneration to improve resource depletion and secure scarce resources is drawing attention. However, with a recycling business, the expense is required for recovery and
reproduction of EOL. Therefore, it is necessary to estimate the cost by determining
the location and recovery route of the recycling site. Furthermore, in order to maintain a high recovery rate, it is necessary to prevent and protect the risk of spilled
EOL to overseas. Therefore, in order to continue maintaining a recycling business,
after evaluating risk and economic efficiency in advance, it is necessary to design
a system. Furthermore, the overseas outflow of many used products is caused in
the pursuit of high profits in recent years. For that reason, the overseas outflow
of EOL also causes the outflow of rare earth indispensable to manufacture of the
high-tech machine included in used products. If foreign spills occur, countries that
cannot produce rare earth in their own country will run out of resources. This lack
of resources can reduce the productivity of high-tech products. In other words, if
it not only can pursue the present profits but the risk and economic efficiency of
a recycling business can be evaluated by taking future value into consideration, it
will become possible to build the maintainable recycling system which foresaw the
future. If it is possible to construct a recycling system for next-generation vehicles
whose production number is increasing with CO 2 emission regulations and the trend
of the times, overseas spills of rare earth such as neodymium are prevented and future
recycling Business will be better. This study considers collecting rare earths from a
next-generation car, and reproducing, and aims at performing economic efficiency
