REPURPOSED Season 3: Aluminum
REPURPOSED: Season 3 traces the aluminum life cycle from places like Sierra Recycling and Demolition in California to Toyota's manufacturing plant in Troy, Missouri, and Missouri Smelting Technology, a key supplier for the automotive industry. With each stop, the series demonstrates how recycled aluminum is not only more sustainable than virgin material, but essential to making engine blocks, transmission housings, and wheels found in millions of cars on the road today.
The series highlights the people and communities behind the scenes, those who operate the furnaces, pour the molten metal, and drive innovation through sustainability and skill. From high-tech manufacturing to real-world recycling, REPURPOSED continues to spotlight an industry that's shaping the future of manufacturing.
"This season proves recycled aluminum isn't just part of the process, it is the process," says John Sacco, president of Sierra International Machinery.
