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.
