The afterlife of aerospace aluminum: Constellium and TARMAC’s flight path to circularity
Written by Nicholas Bell
Aluminum recycling in aerospace has long been an uphill battle. Even though aircraft are full of high-value aluminum, most of it never finds its way back into high-performance aerospace alloys as scrap. Instead, it’s “downcycled” – melted into automotive castings, industrial products, or ends up as DeOx for steel consumption.
But a new partnership involving Constellium and TARMAC Aerosave is trying to break that pattern, and it might have the right mix of players to do it.
