This week's theme is the Circular Economy, Evelyn Lopez and the Earth911 team talk recycling swords, pet food packaging, and old deck stain and cleaners. You'll hear about Art From Scrap, a project of Santa Barbara, Calif.-based Explore Ecology that makes upcycling a citywide activity. We explore the introduction of lab-grown meat, which writer Vic Bondi described as "savory" but not exacly like meat, as well as the relaxation products that are environmentally friendly. Mitch Ratcliffe interviews John Atcheson, cofounder and CEO of Stuffstr, an app that will let you track what you buy at a retailer and resell it later at the touch of a button.
