Be they powered by fossil fuels, batteries, or hydrogen, cars are here to stay. So what can be done to make tires greener? In this episode of  Stereo Chemistry, C&EN reporters Alex Scott and Craig Bettenhausen look at where the rubber meets the road, literally. Scott examined efforts to make tires more sustainable in a recent cover story for C&EN. He found people working on the movement and fate of tiny specks of tire-and-asphalt dust in the environment as well as large-scale efforts to shift to biobased and recycled raw materials when making new tires.      C&EN Uncovered, a project from C&EN’s podcast, Stereo Chemistry, offers another look at subjects from recent cover stories.
