Quick Summary
- Researchers have developed a new process to recycle aluminium scrap from cars,which could reduce waste and carbon emissions associated with producing virgin aluminium.
- Traditionally, scrap aluminium in vehicles is used for low-grade alloys like engine blocks in combustion engines. With the shift to electric vehicles,these materials risk becoming unusable.
- The method involves melting all the scrap aluminium alloys from vehicles in one go, including impurities, and reheating it at 500°C for 24 hours to transform its properties.
- The resulting material rivals standard automotive alloys in strength and can be used for components like chassis and frames using existing industrial processes.
- Challenges cited include proving its suitability for stringent tests required for car body parts,controlling alloy consistency given variable sources of vehicle scrap,and scaling up production effectively.
