As plastic increasingly chokes the world’s landfills, and China announced last year it didn’t want to buy recycled plastic anymore, the what to do with it all has become a pressing question.

One European firm already is combining plastic pellets with hot-mix asphalt to resurface roadways. A U.S. company says that once it finds financial backing, its product “could be deployed within six months” with a process that combines asphalt milled from the road’s surface with plastic urethane.
