In this episode of ShapeMakers, Lynn Brown and Rue Rogers discuss the intersection of aluminum extrusion and the circular economy. They explore how aluminum can be recycled effectively, the importance of maintaining materials in circulation, and the role of scrap in the industry. The conversation highlights the sustainability initiatives within the aluminum extrusion sector and the potential for increased recycling efforts.

Takeaways
The circular economy aims to keep materials in circulation indefinitely. Aluminum has a high recycling rate, with 75% still in use today. Recycling aluminum does not degrade its properties, allowing for high-quality applications. Aluminum can be used over and over without any degradation of properties. The industry uses a mix of virgin and recycled aluminum, typically around 25% virgin and 75% scrap. Recycled aluminum billet can be used just like billet made from prime or virgin aluminum; it does not need to be downgraded to be used in lower performance applications because of its scrap content like other materials. Post-consumer scrap includes materials from product end-of-life, such as old windows and doors, wheels, wire and other building components. Anodized aluminum can be recycled similarly to unfinished aluminum, while painted aluminum poses challenges. The infrastructure for collecting and processing aluminum scrap is well-established in North America. There is potential to increase the use of post-consumer scrap in the industry. Aluminum's corrosion resistance contributes to its long lifespan in applications. The aluminum extrusion industry is actively working on improving recycling processes.
