The growing popularity of recycled aluminum in the car manufacturing process

27 Mar 2018


As the world strives towards becoming more environmentally friendly, car manufacturers are seeking ways to be more sustainable in the production process. Leading manufacturers are increasing the use or adoption of recycled aluminum in the manufacturing of car bodies. This helps in the reduction of waste and carbon emission.

As high carbon emission has negative effects in the world we live in due to the impact on climate change. High carbon emissions are believed to have contributed to an increase in radioactive warming by 31% increase when compared with the previous decades. Transportation services in the form of cars or vehicles are believed to account for about 7% increase in greenhouse gas emissions from 1990-2008. Automobile manufacturers do understand that failing to reuse recycled parts such as aluminum will contribute to the increase of carbon emissions which leads to global warming and depletion of natural resources.

A leading automobile manufacturer in Jaguar launched a £2 million initiative, known as REALITY (Recycled Aluminum through innovative technology). To ensure this project is a success, a target has been set for the recycling of aluminum vehicles at the end of their life. As scraping of old vehicles gains popularity, the aluminum from body parts can easily be recycled towards the production of new vehicles. Aluminum is one of the most recycled parts in an end of life vehicle. Other useful recyclable parts from scrap vehicles include tires, windshield glass, batteries, car seats, radiators, oil filters and mats.

The REALITY project by Jaguar land rover is aimed at using recycled aluminum to produce high-performance cars. It is a 34-month project that should support the adoption of sensor-based scrap sorting technology that would lead to the easy separation of cast alloys and wrought. This advanced technology will lead to the further segregation of wrought alloys into different types in high numbers.  This is the first time a technology had been developed that can separate alloys on this scale.

As an advanced form of technology, the shredding of scrap cars will be efficiently sorted through the use of leading sensing and sorting applications. This leads to the generation of complete recycled scrap sheet and castings. The remnant wrought and cast strap recovered from the shredding and recycling process can be alloyed and released for large-scale casting production. The process is thorough as it uses a vacuum die casting that ensures all impurities are removed.

It is evident that leading automobile manufacturing companies understand the true impact of high carbon emissions and are now adopting advanced technological processes to recycle and use old car parts like aluminum. This will go a long way to reducing the carbon footprint we are confronted with in today’s environment.
