Nissan Rogue built using a ‘closed-loop’ recycling system for aluminium

The all-new 2021 Nissan Rogue is the company’s first global model built using a ‘closed-loop’ recycling system for aluminium parts, Nissan says.

The ‘closed loop’ system helps reduce CO2 emissions compared with using parts made with primary alloys from raw materials, the Japan-based car firm says.

It says it also ‘promotes’ the use of materials that don’t rely on newly mined resources, as well as the reduction of waste from factories.

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.

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.

Recycling and reusing

At the core of 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 aluminium grades separate.

The separation ensures that Nissan can return ‘high-quality scrap’ to suppliers. The suppliers turn the separated and reprocessed aluminium scrap into aluminium alloy sheets and redeliver them to Nissan for use in production.

According to the US-based Aluminum Association, recycling scrap aluminium saves more than 90% of the energy needed to create a comparable amount from raw materials.

The organisation estimates that nearly 75% of all aluminium made is still in use.

Under the Nissan Green Program 2022, Nissan aims to replace 30% of the raw materials used in cars built in 2022 with materials that don’t rely on newly mined resources.

To achieve this, the company says it will use recycled materials and develop biomaterials, carry out recycling activities both at suppliers and in-house, and seek to reduce the weight of car bodies.
