Where Does Plastic And Other Trash Go After We Throw It Away?

Have you ever gotten to the end of, say, a jar of peanut butter and wondered if it should go in trash or recycling? If it’s worth rinsing out? And where will it actually end up?

Journalist Alexander Clapp had those same questions, and went to great lengths to answer them—visiting five continents to chronicle how our trash travels. Along the way, he discovered a multibillion dollar trash trade run by shady waste brokers, and a global industry powered by slimy spoons, crinkled plastic bags, and all the other stuff we throw away. It’s a putrid business that we’re a part of, and many of us know little about.

Host Flora Lichtman speaks with Clapp about the garbage business and his new book Waste Wars: The Wild Afterlife Of Your Trash.
