Recycling: Turning Trash into Treasure
Recycling used to just be called "scrap metal salvage" and it was thought of as an unsavory practice. That all changed as recently as the 1970s, when it became the curbside amenity it is today and part of a multi-billion-dollar industry. Now, the question isn't can we recycle, but can we recycle everything? Innovators in the field are trying to find out. Find out more about these innovators like Carl Zimring, Tom Szaky, Martin Bourque, Jim Puckett, Peter Christensen and Veena Sahajwalla on an all-new episode of Trailblazers.
