Horizontal Recycling of Aluminum for High-Speed Rail: A World First for
the New N700S Shinkansen Train for the Tokaido Shinkansen Line
“From Shinkansen to Shinkansen”

Harita Metals Co., Ltd. (based in Takaoka City, Toyama; representative director
Makoto Harita) is proud to announce a horizontal recycling system establishedin collaboration with the Central Japan Railway Company, to provide materials
for new high-speed Shinkansen trains, made from decommissioned Shinkansentrains.

◆ Overview
To date, Harita Metal has performed research on horizontal recycling of aluminum,through demonstration projects for both the Ministry of Economy, Trade, and Industry(METI) and the New Energy and Industrial Technology Development Organization(NEDO).
To build on the results of this project, the Central Japan Railway Company; Nippon
Sharyo, Ltd.; Hitachi, Ltd.; and Sankyo Tateyama, Inc. have all come together to bringabout horizontal recycling of the aluminum materials used for the Shinkansen. In thehigh-speed railway industry, safety is of the utmost importance; in the world’s firstproject of its kind, we have horizontally recycled materials for use in new train cars.

Demonstration Project to Save Energy by Bringing About a Train
Car Recycling System Combining Arterial and Venous Industries
Through the development of technologies that enable horizontal aluminum recycling by sortingaluminum alloys by type, and efforts to develop an authentication standard for schemes thatcombine both arterial and venous industries, we have developed a train car recycling system.
<Background and Objectives>
Decommissioned
Recycling Processing
Roughly half of all train cars are made ofTrain Cars
aluminum in order to reduce their weight,
and after decommissioning, this aluminumis cascade-recycled for use in applications
such as automobile engine blocks. For highdegree applications of recycled aluminum,
it is necessary to develop technology toperform solid sorting by alloy; through this,Positive environment for materials & information
we aim to build an energy-saving closedloop, bringing about horizontal recycling.
<Details of Demonstration Project >We built an aluminum sorting system fortrain cars, using LIBS* sorting technology.
We have also established the Promotion
Committee for Horizontal Recycling ofAluminum Train Cars, which works with both Train Production

❖ Press Release ❖◆ Looking Ahead
By bringing about this aluminum horizontal recycling system for Shinkansen trains, andfurthering the technologies it uses, we aim to further develop recycling, such as byexpanding the range of materials eligible for this process. There is also a need for thesocietal system to transition from a linear economy to a circular economy. While ourproject has been focused mainly on aluminum alloys, we are also engaged in research onapplicability to other resources, such as steel and copper. This circular system andrecycling technology can be expanded to other materials and used products, which willserve a role in the construction of broader circular economy systems in the future. We
aim to maximize added value created through the efficient use of resources, and bringabout a sustainable society with continuous economic growth and a reduced impact onthe environment.
