Mark Bowles, founder of the ecoATM, talks about the high-tech tools needed to turn flip phones and old electronics into a successful commercial enterprise that helps save the environment. They have kiosks placed all around the United States where people can turn in their unwanted electronics for cash. By recycling unwanted cell phones, ecoATM is able to cut down on the creation of new phones. Instead of purchasing and consuming endless numbers of new phones, ecoATM allows people to buy used or refurbished phones. Part of the Scientists and Engineers On Sofas Series.
