Circular Economy for Automotive Shredder Residue
- Oak Ridge National Laboratory (ORNL), Oak Ridge, TN (United States)
Vehicle production has grown substantially worldwide, and subsequently, End-of-Life (EoL) vehicles entering retirement will grow as well. For example, China, the largest passenger car market worldwide, is expected to have 26.3 million passenger vehicles retiring by 2030. Most vehicles are shredded at EoL to recover metals for the robust metal recycling industry, leaving behind a slew of unwanted materials called automotive shredder residue (ASR) on the order of millions of tonnes every year. Additionally, the average weight of vehicles has gone up to 2600 lbs (1180 Kg) for a small passenger internal combustion engine (ICE) vehicles, 4000 lbs (1814 Kg) for large ICE vehicles, and the electric vehicle (EV) versions are substantially heavier at 1000 lbs (454 Kg) or more compared to combustion engine counterparts. While the increase in weight in EVs is increasing primarily due to the batteries needed to power the car, the materials being substituted into either type of vehicle to reduce weight are polymers and composites.
