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.

Andrew Dent: To eliminate waste, we need to rediscover thrift

Nanocellulose, a tree derivative, mirrors carbon fiber's strength, offering a sustainable, strong, and transparent material.

Revolutionary recycling method for plastics allows infinite reuse, potentially ending the material's environmental toll.

Reviving thrift: Embrace resource reuse to reduce the 1.3 billion tons of annual landfill waste and foster economic benefits.
