In order to comply with the resource recovery incentive system scheduled to be implemented from 2026, we developed VIN number reading software using AI-OCR with the aim of accurately managing ELVs and removed parts. After reading the VIN numbers of approximately 1,000 vehicles, it became clear that VIN numbers were not standardized in Japan, and the number of digits and type of plates varied depending on the manufacturer, making them difficult to read. Furthermore, based on the results, we considered ways to further improve the accuracy of the software.

Battery closed loop recycling will be indispensable in the future, because there is a concern of the shortage of battery resources and the increasingly stringent regulations on recycling.
In this paper, the performance of battery using electrolyte solution with lithium extracted from used lithium-ion batteries is reported.

In order to realize a circular economy for automobiles, it is considered necessary to develop a strategy based on an evaluation that includes resource recycling and economic efficiency, in addition to CO2 emissions. In this study, we devised an evaluation index for automobiles that takes into account recycling and the economic costs on users.
