JLR Targets Increased Use of Recycled Aluminum
Aluminum already is one of the most widely recycled materials in the world.
In fact, nearly 75% of all the aluminum ever produced in the U.S. and Europe still is in use today, Jaguar Land Rover says, citing data from the Aluminum Assn. This includes aluminum recycled from cars and trucks at the end of their lifecycles.
However, the carmaker notes, only a small amount of the aluminum content in new vehicles comes from recycled sources. JLR views this as an opportunity.
Closing the Loop
Currently, most aluminum from end-of-life vehicle scrap is re-used for low-end applications, such as beverage cans, bottle tops and foil food trays.

But JLR says new separation technologies allow aluminum car parts to be repurposed back into the automotive process. Under the REALITY Aluminum research program, the carmaker has demonstrated how recycled aluminum parts can be mixed with a lower amount of primary aluminum to form a prototype alloy with the comparable grade and quality of first-use material applications.
Creating parts from recycled aluminum requires as little as 10% of the energy as that derived from raw material production.
As a result, JLR estimates that it can cut carbon dioxide emissions generated from the production of aluminum by 26%.
“This project has allowed us, for the first time, to recover premium automotive-grade aluminum from scrapped vehicles and re-use its unique properties,” says Gaelle Guillaume, JLR’s lead project manager for the REALITY initiative.
Half of the Jaguar XE’s body structure is made of aluminum alloy grades that contain a significant amount of recycled aluminum, according to the carmaker. The company boasts that, over the last six years, about 300,000 metric tons of recycled aluminum have been repurposed that way.
It’s all part of JLR’s Destination Zero initiative. As the name implies, the goal is to eventually eliminate all CO2 emissions from automotive applications.
Future shared and autonomous vehicle fleets could lend themselves well to recycled materials. JLR says such applications likely will have faster turnover rates and make it easier to plan bulk material strategies.

How carbon fiber is utilized is as different as the vehicles on which it is used. From full carbon tubs to partial panels to welded steel tube sandwich structures, the only limitation is imagination.
The engineers at Zenos Cars have combined recycled carbon fiber, drinking straws and aluminum to create a chassis for a low-volume sports car.
