00:45 A new method to break down plastic polymers

Plastic waste is an enormous problem, with much of it being incinerated or ending up in landfill. One way to give plastics another life is to break them down into their individual components using heat, but this method yields low amounts of usable product. Now, a team demonstrates a proof-of-concept method of heating that wicks the plastic like a candle through a layer of carbon material. They show that this method is more efficient and could be an additional way of breaking down waste plastics.
