Novelis, the world’s largest aluminum recycler, showed Ford how it could afford the switch to higher-priced aluminum (adding about $750 per truck) by using recycled scrap instead of buying virgin aluminum mined from bauxite. Together they created an innovative supply chain that allows Ford to recover a big chunk of its aluminum costs by selling the scrap back to its suppliers and reusing it. The rest of the industry is watching closely. Tough new fuel-economy laws require automakers to double their fleetwide average to 54.5 mpg by 2025.
Here’s how it works: When a vehicle body panel is stamped, about 40% of the metal winds up as scrap. Instead of gathering up all the various metal scraps from its stamping plants, Ford installed pneumatic scrap-handling equipment that will separate the aluminum alloy on conveyors and deposit the scraps in dedicated containers. Novelis contracted a fleet of 150 trailers to ship the scrap back to its plant for reprocessing. The scrap is then melted in a 2,000-degree furnace. Once the molten metal is ready, it is cast into massive 30,000-pound ingots for subsequent processing. It’s then ready to be rolled into sheets 1/16 of an inch thick and shipped in giant coils back to Ford’s stamping plants, where the process begins anew.
Novelis’ goal is to have 70% recycled content in its automotive sheet by 2020, up from 10% five years ago.
