Aluminum Automotive Recycling and Materials Selection Issues

Different scenarios for aluminum usage in automotive body structure are examined with emphasis on the potential effects on recycling. Alloy selection issues are addressed with regard to the limits on absorption of recycled automotive scrap into new cast or wrought products. The difference between “open loop” and “closed loop” recycling is discussed. Possible impacts of increased aluminum usage on the needs for separation technology and recycling infrastructure are reviewed briefly.
