Gary Halada wants to find innovative approaches to recycling and repurposing the clothes Americans throw away. Host Heather Lynch and Halada, associate professor in the Department of Materials Science and Engineering, discuss the growing problem of textile waste globally. Halada shares his research on maintaining the valuable cotton fibers during recycling, creating sustainable building materials from recycled textiles, and the concept of circular economy. They also explore additive manufacturing (3D printing) as a more sustainable alternative to traditional manufacturing techniques.
