Second only to diapers when it comes to taking up landfill space, around 3.5 billion pounds of carpet are tossed each year in the U.S. And because carpets made up of such a complex array of chemicals, they’re next to impossible to recycle. That’s set to change after Dutch manufacturing company DSM teamed with tech startup Niaga to devise a way to manufacture fully recyclable carpets using just one material—polyester. The second-largest carpet distributor in the U.S., Mohawk, has now adapted that technology into a new line of carpets that will hit the consumer market later this year.
