The company revealed the system helps reduce carbon dioxide emissions when compared with using parts made with primary alloys from raw materials. The new system also promotes the use of materials that don’t rely on newly mined resources, as well as the reduction of waste from factories.
In the statement, the company claims that the hood and doors of the 2021 Rogue are stamped from aluminium alloy, a material that reduces vehicle weight and helps improve fuel efficiency and power performance. The model is built in Kyushu, Japan, and Smyrna, Tennessee in the United States.
To support the process, Nissan has collaborated with Kobe Steel, Ltd. and UACJ Corp. in Japan, and with Arconic Corp. and Novelis Inc. in the U.S.
The closed-loop recycling system is a large pneumatic conveyance system. As hoods and doors are stamped into shape, scrap material is shredded and extracted, keeping aluminum grades separate.
Nissan claims that the separation ensures that the company can return high-quality scrap to suppliers. The suppliers turn the separated and reprocessed aluminum scrap into aluminum alloy sheets and redeliver them to Nissan for use in production.
According to the U.S.-based Aluminum Association, recycling scrap aluminum saves more than 90% of the energy needed to create a comparable amount from raw materials. The organization estimates that nearly 75% of all aluminum made is still in use.
