There's no such thing as throwing something away, says Andrew Dent -- when you toss a used food container, broken toy or old pair of socks into the trash, those things inevitably end up in ever-growing landfills. But we can get smarter about the way we make, and remake, our products. Dent shares exciting examples of thrift -- the idea of using and reusing what you need so you don't have to purchase anything new -- as well as advances in material science, like electronics made of nanocellulose and enzymes that can help make plastic infinitely recyclable.
