Ford recycles as much as 20 million pounds of aluminum stamping scrap per month, which could produce the equivalent of 30,000 F-150 bodies each month, according to Ford.

The scrap is used to create parts to build F-150s at Ford’s Dearborn Truck and Kansas City assembly plants.

The recycling is conducted at Ford’s stamping plant in Dearborn, Mich. by way of a closed-loop system, according to the company.

Weight savings from aluminum alloy helps F-150 reduce its lifetime emissions compared to the previous steel-body version. Between 30% and 40% of a typical aluminum coil is turned into scrap in the stamping process, which is recycled into new metal for the truck.

Recycled aluminum avoids 95% of the greenhouse gas emissions associated with primary aluminum production, and it uses significantly less energy and water.
