Imagine wearing a T-shirt made out of ... spoiled milk. In our latest episode of Planet Forward, seen on PBS's Peril and Promise and produced in association with ASU's Global Futures Laboratory, we meet a young climate innovator who is taking the issue of food waste into his own hands. We speak with Robert Luo, a 24-year-old CEO who was inspired by — yes — expired milk. He saw a product that was going to waste, and, using science, he turned it into a fiber that he now weaves into sustainable T-shirts. We also meet Greta Hardy-Mittell, a sophomore at Carleton College, who highlights the work of students on campus to eliminate piles of plastic waste from dining services. It's a program that took just a year to get going — driven by students, propelled by the pandemic. Robert and Greta will impress you with great ideas, powered by imagination and innovation, that inspire action.
